1.34	30-Nov-2024	christos	Create a new header lwp_private.h to contain _lwp_getprivate_fast, _lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that: 1. we don't need special hacks to hide them 2. we can include <lwp.h> where needed to get the necessary prototypes without redefining them locally.
1.33	19-Dec-2018	maxv	branches: 1.33.36; Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently, but also as discussed several times in the past.
1.32	12-Jul-2018	maxv	Remove the kernel PMC code. Sent yesterday on tech-kern@. This change: * Removes "options PERFCTRS", the associated includes, and the associated ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is good. * Removes the PMC code of ARM XSCALE. * Removes all the pmc.h files. They were all empty, except for ARM XSCALE. * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The definitions are put in sysarch.h. * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control and sys_pmc_get_info syscalls. They are marked as OBSOL in kern, netbsd32 and rump. * Removes the pmc_evid_t and pmc_ctr_t types. * Removes all the associated man pages. The sets are marked as obsolete.
1.31	29-Mar-2018	joerg	branches: 1.31.2; Move the complex logic for dynamically writing branches from ld.elf_so into a header for reuse in crt0.o for static ifunc support. Change the existing logic for sparc64 to use the Bicc variant of ba,a as it allows +-8MB displacement compared to the BPcc variant's +-1MB. Teach the sparc variant the same trick for using ba,a and not sethi+jmp when possible.
1.30	23-Jul-2014	alnsn	branches: 1.30.26; Rename sljitarch.h to sljit_machdep.h.
1.29	01-Feb-2014	nakayama	branches: 1.29.2; Make sljit usable on sparc64 32-bit kernels.
1.28	17-Jul-2011	joerg	branches: 1.28.2; 1.28.12; 1.28.16; Retire varargs.h support. Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.27	09-Jul-2011	dyoung	Don't install sparc64/bus.h any more.
1.26	13-Apr-2011	mrg	install <machine/intr.h> for crash(8). (we could avoid this, but it would require a lot of contortions that make the header files ugly. maybe someone else can figure out a less ugly way of doing this later.)
1.25	31-Jan-2011	christos	fenv support for sparc64 from Stathis Kamperis
1.24	09-Feb-2007	ad	branches: 1.24.70; 1.24.76; 1.24.78; Merge newlock2 to head.
1.23	26-Jul-2006	drochner	branches: 1.23.4; don't install <machine/db_machdep.h>, this is kernel only
1.22	11-Dec-2005	christos	branches: 1.22.4; 1.22.8; merge ktrace-lwp.
1.21	07-Jul-2004	drochner	branches: 1.21.12; also add <machine/joystick.h> to alpha and amd64, to allow compilation of certain multimedia applications
1.20	08-May-2004	kleink	Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.
1.19	26-Aug-2003	uwe	Drop fbvar.h from INCS now that it's been cvs rm'ed here.
1.18	18-Jan-2003	thorpej	branches: 1.18.2; Merge the nathanw_sa branch.
1.17	26-Nov-2002	lukem	Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.
1.16	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.15	07-Aug-2002	briggs	Implement pmc(9) -- An interface to hardware performance monitoring counters. These counters do not exist on all CPUs, but where they do exist, can be used for counting events such as dcache misses that would otherwise be difficult or impossible to instrument by code inspection or hardware simulation. pmc(9) is meant to be a general interface. Initially, the Intel XScale counters are the only ones supported.
1.14	19-Sep-2001	thorpej	branches: 1.14.4; 1.14.8; 1.14.12; Use <dev/sun/fbio.h>, not our own copy.
1.13	15-Apr-2001	kleink	branches: 1.13.2; 1.13.4; Add definitions of C99 integer format conversion macros. XXX Fastest minimum-width integer types haven't been decided upon yet.
1.12	15-Apr-2001	kleink	Add definitions of C99 specified-width integer type limits. XXX Fastest minimum-width integer types haven't been decided upon yet.
1.11	14-Apr-2001	kleink	Add definitions of C99 integer constant macros. Tidy Makefiles up a little.
1.10	14-Apr-2001	kleink	Add definitions of C99 minimum-width and greatest-width integer types. XXX Fastest minimum-width integer types haven't been decided upon yet.
1.9	16-Aug-2000	mrg	branches: 1.9.2; backout previous; unintentional.
1.8	16-Aug-2000	mrg	include the sparc loadfile_machdep.h as-is; we can blow this header away completely later.
1.7	26-Jun-2000	kleink	Add <machine/int_types.h>, which provides namespace-pure definitions of exact-width integer types.
1.6	29-Apr-2000	thorpej	Oops, install <machine/lock.h> on these systems, too.
1.5	17-Mar-2000	tron	Install "machineendian_machdep.h".
1.4	23-Dec-1999	kleink	C99: Define a NAN macro in <math.h> which evaulates to a constant expression of a single-precision quiet NaN; only to be defined on platforms that do support this value.
1.3	27-Nov-1999	mrg	these files were removed years ago (exec.h was not even installed).
1.2	15-Jan-1999	bouyer	branches: 1.2.8; 1.2.14; Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.

1.19	07-May-2019	kamil	Switch all users (except ia64) of custom machine/ansi.h to common_ansi.h Deduplicate the code among ports and poll definitions of types directly from a compiler. This fixes miscompilation of certain programs that instruct compilers to generate code for different types. This bug has been detected with -fshort-wchar in EFI firmware. Proposed and discussed on a mailing list (twice). Itanium uses custom !ELF fallback switch, temporarily leave it as it is.
1.18	17-Jun-2015	martin	branches: 1.18.18; Make clock_t unsigned
1.17	17-Jul-2011	joerg	branches: 1.17.12; 1.17.28; 1.17.30; Retire varargs.h support. Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.16	27-Mar-2010	tnozaki	1. {wctype,wctrans,mbstate}_t: switch MD to MI like other libc implementation (such as BSD and glibc2). 2. don't typedef void wc{type,trans}_t, suggested by soda@-san. it may pass through compiler type check, it's harmful. so i introduce dummy struct __tag_wc{type,trans}_t(iconv_t already does). no ABI change was made.
1.15	11-Jan-2009	christos	branches: 1.15.4; 1.15.6; merge christos-time_t
1.14	17-Oct-2007	garbled	branches: 1.14.16; 1.14.18; 1.14.22; 1.14.30; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.13	03-Sep-2007	drochner	clean up some definitions around rune_t which are not needed anymore
1.12	04-Oct-2006	tnozaki	branches: 1.12.8; 1.12.16; 1.12.22; 1.12.26; 1.12.28; fix gcc -Werror -Wmissing-braces problem mbstate_t(this is opaque object)'s initializer should be ``{ 0 }'', so changed 1st field of union from character array to integer.
1.11	11-Dec-2005	christos	branches: 1.11.20; 1.11.22; merge ktrace-lwp.
1.10	20-Apr-2005	matt	branches: 1.10.2; For GCC3 and later, use the __builtin_va* constructs.
1.9	07-Aug-2003	agc	branches: 1.9.8; 1.9.14; 1.9.18; Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.8	02-Mar-2003	tshiozak	branches: 1.8.2; add some ISO C 1995 I18N functions and types: btowc, wctrans, towctrans, wcscoll, wcsxfrm, wctype_t and wctrans_t.
1.7	03-Jan-2001	takemura	replace 'long long' with int64_t to compile stand alone program with compiler other than GCC.
1.6	26-Dec-2000	itojun	make mbstate_t bigger (32 -> 128 bytes). XXX if you have libc after citrus locale import, please recompile libc, and your applications that use mbstate_t (rather rare). really sorry for the mess.
1.5	21-Dec-2000	itojun	populate _BSD_MBSTATE_T_. add warning regarding to rune_t.
1.4	27-Jun-2000	kleink	G/c _BSD_INTPTR_T_ and _BSD_UINTPTR_T_.
1.3	31-Jul-1998	ross	branches: 1.3.12; 1.3.20; Following discussions with eeh and mrg, change most of these types so that they should make an ILP32 setup with an ILP32 compiler and an LP64 setup if run through an LP64 compiler. None of the data sizes actually change right now, and any type errors that show up would have to be fixed eventually anyway.
1.2	07-Jul-1998	eeh	branches: 1.2.2; General update: Added genassym.cf Removed lderr which should never have gotten in Removed lots of dead code from locore.s Added some softint stuff to intr.c Added support for halt -p esp and le both use bus_dmamap_*() functions now instead of kdvma_mapin() groundwork for PCI (but we still have no drivers for any sun4u PCI devices)

1.1	20-Jun-1998	eeh	branches: 1.1.1; Initial revision
1.1.1.1	20-Jun-1998	eeh	branches: 1.1.1.1.28; 1.1.1.1.32; 1.1.1.1.40; Import of sparc64.

1.1.1.1.28.1	06-Sep-2002	jdolecek	sync kqueue branch with HEAD
1.22	17-Oct-2015	nakayama	Move LP64 and ILP32 conversion macros COMBINE, SPLIT from locore.h to asm.h, and provide SPLIT_RETL for the case SPLIT and then retl immediately.
1.21	28-Apr-2013	nakayama	branches: 1.21.12; Use macros in machine/asm.h instead of locally defined, and introduce CASPTRA for casxa/casa.
1.20	16-Mar-2013	christos	move the useful macros somewhere where they can be used in userland.
1.19	20-Jul-2002	mrg	branches: 1.19.146; 1.19.156; use <sparc/foo.h> where appropriate. now these files become very very difficult to get out of sync. add bootinfo.h and promlib.h (using the same method) so that sparc64 headers can build sparc stand (not yet finished.)
1.18	24-Jun-2002	thorpej	Add ENTRY_NOPROFILE().
1.17	14-Jan-2002	eeh	branches: 1.17.8; Use a more efficient PIC_PROLOG().
1.16	03-Nov-2001	thorpej	branches: 1.16.2; Changes from Martin Husemann and myself: - Make the 32-bit SPARC profile support work with the GCC 2.95.3 SPARC ELF compiler, which uses a different name for mcount. - Make the 64-bit SPARC profile support header look more like the 32-bit SPARC header (no functional change -- 64-bit SPARC already used the correct mcount name).
1.15	02-Aug-2000	eeh	branches: 1.15.4; 1.15.6; Get kernel profiling to work. Now if only gprof worked....
1.14	01-Aug-2000	eeh	Pull in <machine/frame.h> to define BIAS and CC64FSZ.
1.13	23-Jul-2000	eeh	Include <machine/frame.h> to get the definition of BIAS and CC64FSZ.

1.7	02-Dec-1998	thorpej	Argh, fix the ANSI CPP version of the a.out WARN_REFERENCES().
1.6	02-Dec-1998	thorpej	Implement WARN_REFERENCES().
1.5	06-Oct-1998	eeh	Fix PIC code initialization.
1.4	13-Sep-1998	eeh	Fixup signal changes (hopefully). However SUN_COMPAT is likely broken by this and I don't know how to fix it. We can now exec a 64-bit init through a really ugly hack (don't ask.)
1.3	13-Aug-1998	eeh	Merge paddr_t changes into the main branch.
1.2	07-Jul-1998	eeh	branches: 1.2.2; General update: Added genassym.cf Removed lderr which should never have gotten in Removed lots of dead code from locore.s Added some softint stuff to intr.c Added support for halt -p esp and le both use bus_dmamap_*() functions now instead of kdvma_mapin() groundwork for PCI (but we still have no drivers for any sun4u PCI devices)
1.1	20-Jun-1998	eeh	branches: 1.1.1; Initial revision
1.1.1.1	20-Jun-1998	eeh	Import of sparc64.

1.9.12.2	26-Jul-2000	mycroft	Approved by thorpej: Enable pulling this into user-level code to get some definitions (e.g. CC64FSZ). syssrc/sys/arch/sparc64/include/asm.h 1.11 -> 1.13 syssrc/sys/arch/sparc64/include/frame.h 1.6 -> 1.7
1.9.12.1	18-Jul-2000	mrg	pullup the contents of -current arch/sparc64. this gives us significant ultrasparc PCI support (ultra5, ultra10, AXi, and E250 tested so far), plus many other small fixes. netbooting is now supported.
1.9.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.26	26-Sep-2006	martin	branches: 1.26.28; 1.26.34; Rework boot device matching to get rid of lots of special case code and tables to map fimware names to driver names. Based on a suggestion from Eduardo (quite some time ago). Each device (on busses we can handle and care about) gets a device property storing the devices OpenFirmware package handle. To match the boot device, the phandle of the chosen bootpath is compared against this property, plus some additional string matching for disk/cd devices (where OF only provides a node for the device class, not each instance).

This allows the bootloader to detect those kernels which are aware of the new boot scheme - Due to the changes in kernel mapping code, alter secondary CPU bootstrap code to use trampoline just like FreeBSD does (some FreeBSD code is used here as well)

From within the bootloader, when we have readily accessible instance handles of the boot device, it is easy to query more details like SCSI LUN, target, and FC-AL wwn from the firmware.

Add a dmat64 field to various PCI attach structures, and pass it down where needed. Implement a simple new function called pci_dma64_available(pa) to test if 64bit DMA addresses may be used. This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>, and there is more than 4G of memory.
1.44	05-May-2003	martin	Make all non-trivial bus space functions "static __inline" (consistently) and turn all macros with local blocks and declarations into functions. This fixes PR 19975.
1.43	30-Jan-2003	martin	Sparc64 already had a BUS_DMA_NOCACHE - remove one of the two definitions. Fortunately the old (local) one had the same semantics as the new one.
1.42	28-Jan-2003	kent	Introduce BUS_DMA_NOCACHE, and bus_dmamem_map() of i386 supports it.
1.41	10-Dec-2002	pk	Remove the `flags' argument from bus_intr_establish().
1.40	10-Dec-2002	pk	bus_intr_establish() signature change. The additional `fast trap' argument is ignored in these drivers. BUS_INTR_ESTABLISH_FASTTRAP and BUS_INTR_ESTABLISH_SOFTINTR are no longer used.
1.39	21-Mar-2002	eeh	Parenthesise macro arguments.
1.38	20-Mar-2002	eeh	Overhaul bus space. bus_space_handle_t now holds an address and two ASIs, one for normal accesses and one for streaming accesses. This allows to map individual handles different ways, so some can use MMU bypass accesses and others use virtual addresses. bus_space_map() will now create handles that use bypass accesses unles BUS_SPACE_MAP_LINEAR is passed in. So only pass in BUS_SPACE_MAP_LINEAR if you absolutely need to use bus_space_vaddr(). This removes at least one extra level of indirection and should reduce TLB misses. 32-bit kernels have problems accessing 64-bit addresses, so they always use virtual addresses.
1.37	15-Mar-2002	eeh	Get PCI working with the new bus_space*.
1.36	14-Mar-2002	eeh	Get rid of bus_space_map2().
1.35	01-Mar-2002	martin	For aesthetical reasons use bus_addr_t instead of paddr_t in the BUS_ADDR makro. Requested by uwe.
1.34	01-Mar-2002	martin	Cast the "io" parameter of BUS_ADDR to paddr_t before it gets shifted. This makes this makro work with smaller values passed for io. No functional change.
1.33	07-Feb-2002	eeh	Make bus_space_barrier() an inline instead of a function vector.
1.32	24-Sep-2001	eeh	branches: 1.32.4; Change bus_space_mmap() signature to the official one.
1.31	21-Sep-2001	wiz	Update copyright, fix typo and remove too many '/'. Ok'd by eeh.
1.30	21-Sep-2001	eeh	Handle DMA boundaries a bit better.
1.29	10-Sep-2001	eeh	Change some debug printfs to make gcc happy.
1.28	19-Jul-2001	thorpej	branches: 1.28.2; Add BUS_DMA_READ and BUS_DMA_WRITE flags, that hint the back-end at dmamap load time that the mapping will be used for a unidirectional transfer of the specified direction.
1.27	07-Mar-2001	thorpej	branches: 1.27.2; Add the BUS_DMA_STREAMING flag.
1.26	11-Feb-2001	eeh	branches: 1.26.2; Add some extra fields to a dmamap to track what's being mapped.
1.25	22-Sep-2000	eeh	Define __BUS_SPACE_HAS_STREAM_METHODS now we have them.
1.24	16-Sep-2000	eeh	Add bus_spacestream() methods. I hope they work.
1.23	14-Jul-2000	eeh	Make all the inline functions static.
1.22	13-Jul-2000	mrg	remove old (bogus) comment.
1.21	09-Jul-2000	pk	Add a `device class' interrupt level argument (from machine/intr.h) to bus_interrupt_establish(). It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt level to devices in PCI slots.
1.20	07-Jul-2000	eeh	Handle bus_dma aligment properly.
1.19	29-Jun-2000	pk	Fix bus_space_read_region_{2,4,8}().
1.18	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.17	12-Jun-2000	eeh	branches: 1.17.2; More debugging support.
1.16	02-Jun-2000	eeh	Use all 64 address bits in lda()/sta() macros so physical device addresses work. (Also add some bus_space_*() debug hooks).
1.15	22-Apr-2000	mrg	branches: 1.15.2; whole bunch of changes: - merge IOMMU DVMA code from sbus/psycho into iommu.c. this code was identical and a few minor inconsistencies had crept in. this way keeps them all in sync. - with this code gone from psycho, merge the psycho.c and psycho_bus.c files. same with ebus/ebus_bus.c. delete the _bus.c files. - add a _ds_boundary member to the dma segment structure, so that later dma mappings can find this value. - set _ds_boundary in machdep.c:_bus_dmamem_alloc(). - kill much dead code.
1.14	25-Jan-2000	drochner	define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that device accesses are idempotent (but should not be cached by the CPU)
1.13	07-Jun-1999	eeh	branches: 1.13.2; Another general cleanup: Remove the entire idea of fasttrap interrupts since V9 traps are really cheap, the CPUs are really fast, and the completely different trap frames would make these handlers really difficult to implement. pmap_changeprot() was only used by the clock and one other place; deprecate it. probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we can probe IO locations by physical addresses. Some pmap cleanup. Some more copyright cleanup.
1.12	05-Jun-1999	eeh	Fix things up so they compile again.
1.11	22-May-1999	eeh	Fix bus_type_t properly and enable ASI accesses for bus_space_{read,write}*()
1.10	23-Mar-1999	drochner	branches: 1.10.4; Add a macro to check for sufficient pointer alignment in bus.h context, "BUS_SPACE_ALIGNED_POINTER()". Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)
1.9	31-Jan-1999	drochner	make the last fix work as intended
1.8	30-Jan-1999	eeh	Fix problems with bus_space*() macros (thanks M.Drochner).
1.7	06-Sep-1998	eeh	32-bit fixup.
1.6	05-Sep-1998	eeh	It slices. It dices. It does everything except exec a sparc32_compat init.
1.5	02-Sep-1998	eeh	Periodic update: now starts probing devices.
1.4	30-Aug-1998	eeh	Some more 64-bit cleanup. Now everything compiles.
1.3	13-Aug-1998	eeh	Merge paddr_t changes into the main branch.
1.2	07-Jul-1998	eeh	branches: 1.2.2; General update: Added genassym.cf Removed lderr which should never have gotten in Removed lots of dead code from locore.s Added some softint stuff to intr.c Added support for halt -p esp and le both use bus_dmamap_*() functions now instead of kdvma_mapin() groundwork for PCI (but we still have no drivers for any sun4u PCI devices)

1.1	01-Jul-2011	dyoung	Per discussion at <http://mail-index.netbsd.org/tech-kern/2010/04/02/msg007941.html>, divide each machine's bus.h into bus_defs.h (constants & data types) and bus_funcs.h (macro implementations of bus_space(9) routines and MD prototypes). Note that some bus_space(9) routines' implementation will move to .c files from inline subroutines or macros in .h files. I've only made the split for machine architectures where there is PCI. All of the non-PCI-having architectures will require a similar split. These #include files are not referenced by any (committed) Makefiles or header files, yet. Changes to Makefiles, to <sys/bus.h>, and to some more machine-dependent files will dribble in before I throw the switch.

1.12	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.11	16-Aug-2002	petrov	Add sab.

1.9	26-Mar-2001	lukem	branches: 1.9.2; 1.9.8; - add dev_noimpl(xxx,yyy) macro to replace "(dev_type_xxx(())) yyy", and use appropriately - create more helper macros: . cdev__xyz_init(c,n), such as cdev__ocri_init() for / open, close, read, ioctl /, etc. . cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out method `R' and the comments now read / xxx (read) yyy / instead . cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t as well - use seltrue instead of dev_noimpl(poll,), as (IIRC) cdevsw.d_poll should always DTRT WRT returning a valid result. (a few devices previously incorrectly returned ENODEV) - use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty == 0, because it doesn't matter if dev_type_stop isn't implemented in that case, and it allows the use of the cdev__xyz_init macros. certain ports (sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few drivers, whereas everything else uses enodev - ensure that the comments are accurate WRT the behaviour of a given entry
1.8	21-Sep-2000	eeh	branches: 1.8.2; Remove some unsupported devices and add support for the `com' device.
1.7	19-May-2000	eeh	Fix the sparc64 console. Unlike the other Sun machines, UltraSPARCs can have consoles run on different chips than zs, so we need to support them. So, here we go: Add a new PROM console driver with a major number and everything. This is the default driver if nothing else attaches. It does not use the keyboard driver since the PROM translates keystrokes itself. (Unfortunately it also swallows L1-A). Have the keyboard driver take over the console when it attaches on a serial port. When a serial port detects a keyboard and attaches the keyboard driver, it needs to provide a set of consdev vectors. They keyboard driver will use those to send I/O to the keyboard and mouse.

1.134	13-Jul-2023	riastradh	branches: 1.134.6; Break cycle by using `struct kmutex ' instead of `kmutex_t '. sys/sched.h included sys/mutex.h which includes sys/intr.h which includes machine/intr.h which on cats includes arm/footbridge/footbridge_intr.h which includes arm/cpu.h which includes sys/cpu_data.h which includes sys/sched.h But there was never any real need for sys/mutex.h in sys/sched.h, because it only uses pointers to the opaque struct kmutex. Cycle broken by using `struct kmutex *' instead of pulling in sys/mutex.h for the definition of kmutex_t. Side effect: This revealed that sys/cpu_data.h needed sys/intr.h (which was pulled in accidentally by sys/mutex.h via sys/sched.h) for SOFTINT_COUNT. Also revealed some other machine/cpu.h header files were missing includes of sys/mutex.h for kmutex_t.
1.133	14-Aug-2021	ryo	branches: 1.133.4; Improved the performance of kernel profiling on MULTIPROCESSOR, and possible to get profiling data for each CPU. In the current implementation, locks are acquired at the entrance of the mcount internal function, so the higher the number of cores, the more lock conflict occurs, making profiling performance in a MULTIPROCESSOR environment unusable and slow. Profiling buffers has been changed to be reserved for each CPU, improving profiling performance in MP by several to several dozen times. - Eliminated cpu_simple_lock in mcount internal function, using per-CPU buffers. - Add ci_gmon member to struct cpu_info of each MP arch. - Add kern.profiling.percpu node in sysctl tree. - Add new -c <cpuid> option to kgmon(8) to specify the cpuid, like openbsd. For compatibility, if the -c option is not specified, the entire system can be operated as before, and the -p option will get the total profiling data for all CPUs.
1.132	05-Apr-2021	nakayama	Fix build w/o options SUN4V.
1.131	03-Apr-2021	palle	Improve cpu_idle() by allowing a platform specific implementaion (same logic as the sparc implementation) - currently only used by sun4v
1.130	10-Mar-2020	christos	branches: 1.130.4; 1.130.6; kill extra curproc/curlwp definitions that have no chance of working.
1.129	29-Dec-2019	martin	Simplify some macros: if we only ever use them on the local cpu, there is no need to do another pointer derefernence to go via the global address of our cpu info. Pointed out by ad.
1.128	01-Dec-2019	ad	Fix false sharing problems with cpu_info. Identified with tprof(8). This was a very nice win in my tests on a 48 CPU box. - Reorganise cpu_data slightly according to usage. - Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc). - On x86, put some items in their own cache lines according to usage, like the IPI bitmask and ci_want_resched.
1.127	23-Nov-2019	ad	cpu_need_resched(): - Remove all code that should be MI, leaving the bare minimum under arch/. - Make the required actions very explicit. - Pass in LWP pointer for convenience. - When a trap is required on another CPU, have the IPI set it locally. - Expunge cpu_did_resched().

1.124	16-Jan-2018	mrg	branches: 1.124.2; 1.124.4; implement cpuctl identify for sparc and sparc64. sparc: - move enum vactype and struct cacheinfo into cpu.h - move the cache flags from cpuinfo.flags into CACHEINFO.c_flags (this allows the new cache_printf_backend() to see them.) remove unused CPUFLG_CACHEIOMMUTABLES and CPUFLG_CACHEDVMA. - align xmpsg to 64 bytes - move cache_print() into cache_print.h so it can be shared with cpuctl. it only depends upon a working printf(). - if found, store the CPU node's "name" into cpu_longname. this changes the default output to show the local CPU not the generic CPU family. eg: cpu0 at mainbus0: mid 8: Ross,RT625 @ 90 MHz, on-chip FPU vs the generic "RT620/625" previously shown. - for each CPU export these things: - name - fpuname - mid - cloc - freq - psr impl and version - mmu impl, version, and number of contexts - cacheinfo structure (which changed for the first time ever with this commit.) sparc64: - add a minimal "cacheinfo" structure to export the i/d/e-cache size and linesize. - store %ver, cpu node "name" and cacheinfo in cpu_info. - set cpu_info ver, name and cacheinfo in cpu_attach(), and export them via sysctl, as well as CPU ID and clock freq cpuctl: - add identifycpu_bind() that returns false on !x86 as their identify routines do not need to run on a particular CPU to obtain its information, and use it to avoid trying to set affinity when not needed. - add sparc and sparc64 cpu identify support using the newly exported values.
1.123	10-Feb-2017	palle	sun4v: Added handling of trap type 0x034 (address alignment error) + fixed typo mmfsa -> mmufsa. Verified for both sun4u and sun4v using qemu.

1.91	24-May-2010	martin	Make C declarations match assembler reality: ipi functions get two arguments (which most of them (partly) ignore, but anyway).
1.90	28-Mar-2010	mrg	- add a kmutex_t ci_ctx_lock to struct cpu_info, and initialise it in cpu_pmap_init() and replace pmap_ctx_lock usage with this new ci_ctx_lock - replace smp_dcache_flush_page_all() with smp_dcache_flush_page_cpuset(), that flushes only on the set of CPUs not, everyone. add new dcache_flush_page_cpuset() to flush this page from the D$ only on the specified set of CPUs. - add a cpuset to pmap_free_page() and use it when freeing PTE pages when a pmap is destroyed - introduce pmap_free_page_noflush(), and use it when we allocated a page for PTEs but didn't use it and don't need to flush it - don't bother with pmap_lock in pmap_extract(), the only potential issue is pseg_get() which is already safe tested on sb2000, sb2500 and ultra80 with a bunch of various heavy workloads, and seems to give a clear 1-2% speed up for high-forking / short lived processes, such as ./configure.
1.89	06-Mar-2010	mrg	branches: 1.89.2; clean up a bunch of MULTIPROCESSOR: - always include ci_ipi_evcnt[] in cpuinfo - #define sparc_ncpus 1 for !MULTIPROCESSOR - make struct pmap::pm_list an pm_ctx always be an array, and simplify several functions and lookups to always be the same tested on U60 and SB2500 before and after with one and two cpus in an MP kernel, and UP kernels, and i can't find anything besides noise for benchmark issues. (infact, i can't really tell the difference between GENERIC and GENERIC.MP on these systems...)

1.87	21-Oct-2009	rmind	Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.
1.86	30-May-2009	martin	cpu_setfunc() can not use lwp_trampoline, as that has additional lwp startup semantics. Use a simpler setfunc_trampoline instead.

1.67	17-Oct-2007	garbled	branches: 1.67.2; 1.67.4; 1.67.6; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.55	13-Sep-2006	mrg	SMP cleanup. provide support for multiple CPUs in DDB. (SMP itself is still not working.) cpu.h: - add a pointer for DDB regs in SMP environment to struct cpu_info - remove the #defines for mp_pause_cpus() and mp_resume_cpus() cpuset.h: - remove CPUSET_ALL() and rename CPUSET_ALL_BUT() to CPUSET_EXCEPT() from petrov. db_machdep.h: - rename the members of db_regs_t to be the same as sparc - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - redo DDB_REGS to no longer be a pointer to a fixed data structure but to one allocated per-cpu when ddb is entered - move a bunch of prototypes in here intr.h: - remove SPARC64_IPI_ macros, no longer used db_interface.c: - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - make "nil" a 64 bit entity - change the ddb register access methods to work in multiprocessor environment, it is now very much like sparc does it - in kdb_trap() avoid accessing ddb_regp when it is NULL - update several messages to include the cpu number - unpause other cpus much later when resuming from ddb - rename db_lock() to db_lock_cmd(), as the sparc-like code has db_lock as a simple lock - remove "mach cpus" command, and replace it with "mach cpu" (which does the same) and also implement "mach cpu N" to switch to another cpus saved trapframe db_trace.c: - update for the ddb_regs -> ddb_regp change genassym.cf: - add TF_KSTACK as offsetof(struct trapframe64, tf_kstack) ipifuncs.c: - overhaul extensively - remove all normal interrupt handlers as IPI's, we now handle them all specially in locore.s:interrupt_vector - add a simplelock around all ipi functions - it's not safe for multiple cpus to be sending IPI's to each other right now - rename sparc64_ipi_pause() to sparc64_ipi_pause_thiscpu() and, if DDB is configured, enable it to save the passed-in trapframe to a db_regs_t for this cpu's saved DDB registers. - remove the "ipimask" system (SPARC64_IPI_ macros) and instead pass functions directly - in sparc64_send_ipi() always set the interrupt arguments to 0, the address and argument of the to be called function. (the argument right now is the address of ipi_tlb_args variable, and part of the reason why only one CPU can send IPI's at a time.) don't wait forever for an IPI to complete. some of this is from petrov. - rename sparc64_ipi_{halt,pause,resume}_cpus() to mp_{halt,pause,resume}_cpus() - new function mp_cpu_is_paused() used to avoid access missing saved DDB registers - actually broadcast the flush in smp_tlb_flush_pte(), smp_tlb_flush_ctx() and smp_tlb_flush_all(). the other end may not do anything yet in the pte/ctx cases yet... kgdb_machdep.c: - rework for changed member names in db_regs_t. locore.s: - shave an instruction from syscall_setup() (set + ld -> sethi + ld) - remove some old dead debug code - add new sparc64_ipi_halt IPI entry point, it just calls the C vector to shutdown. - add new sparc64_ipi_pause IPI entry point, which just traps into the debugger using the normal breakpoint trap. these cpus usually lose the race in db_interface.c:db_suspend_others() and end up calling the C vector sparc64_ipi_pause_thiscpu(). - add #if 0'ed code to sparc64_ipi_flush_{pte,ctx}() IPI entry points to call the sp_ version of these functions. - in rft_kernel (return from trap, kernel), check to see if the %tpc is at the sparc64_ipi_pause_trap_point and if so, call "done" not "retry" - rework cpu_switch slightly: save the passed-in lwp instead of using the one in curlwp - in cpu_loadproc(), save the new lwp not the old lwp, to curlwp - in cpu_initialize(), set %tl to zero as well. from petrov. - in cpu_exit(), fix a load register confusion. from petrov. - change some "set" in delay branch to "mov". machdep.c: - deal with function renames pmap.c: - remove a spurious space trap.c: - remove unused "trapstats" variable - add cpu number to a couple of messages

1.41	04-Jan-2004	jdolecek	Rearrange process exit path to avoid need to free resources from different process context ('reaper'). From within the exiting process context: * deactivate pmap and free vmspace while we can still block * introduce MD cpu_lwp_free() - this cleans all MD-specific context (such as FPU state), and is the last potentially blocking operation; all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free() * process is now immediatelly marked as zombie and made available for pickup by parent; the remaining last lwp continues the exit as fully detached * MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same for both 'process' and 'lwp' exit uvm_lwp_exit() is modified to never block; the u-area memory is now always just linked to the list of available u-areas. Introduce (blocking) uvm_uarea_drain(), which is called to release the excessive u-area memory; this is called by parent within wait4(), or by pagedaemon on memory shortage. uvm_uarea_free() is now private function within uvm_glue.c. MD process/lwp exit code now always calls lwp_exit2() immediatelly after switching away from the exiting lwp. g/c now unneeded routines and variables, including the reaper kernel thread

1.35	05-Feb-2003	nakayama	branches: 1.35.2; Switch to use cycle counter (%tick) based microtime(). This is derived from alpha/microtime.c and i386/tsc_microtime.c, and will share with both ports. This should fix PR port-sparc64/18452. (approved by martin)
1.34	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.33	27-Nov-2002	pk	Sync machdep sysctls with sparc.
1.32	29-Sep-2002	chs	remove some vestigial FPU and cache code that's not need on ultrasparcs. misc tidiness.
1.31	14-May-2002	eeh	branches: 1.31.4; Have CLKF_BASEPRI() always return false for now to prevent hardclock from being blocked by softclock.
1.30	09-Feb-2002	eeh	Correctly take into account the satck bias in CLKF_INTR().
1.29	03-Sep-2001	mrg	branches: 1.29.6; don't explicitly size the intrhand[] array; fixes PR#13859 from <martti.kuparinen@iki.fi>
1.28	14-Jun-2001	thorpej	branches: 1.28.2; Don't need to prototype child_return() here, it's in <sys/proc.h>.
1.27	15-Jan-2001	thorpej	branches: 1.27.2; Make softclock a generic soft interrupt of the API is available, adding the requisite void * argument to softclock().
1.26	29-Sep-2000	eeh	This seems to fix the interrupt lossage of non-debug kernels.
1.25	28-Sep-2000	eeh	probeget() actually handles 64-bit values so fix the prototype.
1.24	25-Aug-2000	thorpej	Make need_resched() take a "struct cpu_info *" argument. This causes gives a primitive form of processor affinity. Its use in roundrobin() still needs some work.
1.23	03-Jul-2000	eeh	Prevent interrupts from being posted if they are active and deprecate polled interrupts. This seems to eliminate the spurious interrupts.
1.22	02-Jul-2000	eeh	Clean up interrupt handling some more.
1.21	30-Jun-2000	eeh	Fix interrupt delivery on UltraSPARC IIi machines.
1.20	19-Jun-2000	eeh	branches: 1.20.2; Have separate data and text segments, make text read-only.
1.19	12-Jun-2000	eeh	Start reorganizing the kernel for MULTIPROCESSOR support.
1.18	12-Jun-2000	mrg	ih_map & ih_clr are volatile.
1.17	26-May-2000	thorpej	branches: 1.17.2; First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state: - Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future. - Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU). - Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate. - All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made. Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.
1.16	16-Mar-2000	eeh	Revamp interrupts again: Fix a bug causing interrmittent panics in interrupt dispatch. Use interrupt vectors for softints. Add a new send_softint interface. Improved D$ flushing. Improve traptrace and other debugging enhancements.
1.15	30-Dec-1999	eeh	Make CLKF_INTR() more intelligent.
1.14	06-Nov-1999	eeh	Provide explicit 64-bit and 32-bit types for compatibility with sparc userland.
1.13	11-Oct-1999	eeh	branches: 1.13.2; 1.13.4; Update to post 1.4.
1.12	10-Aug-1999	thorpej	branches: 1.12.2; Define cpu_number() as discussed on tech-smp.
1.11	20-Jun-1999	eeh	Move the DVMA mapin/mapout functions from the SBus driver to the iommu driver.
1.10	07-Jun-1999	eeh	Another general cleanup: Remove the entire idea of fasttrap interrupts since V9 traps are really cheap, the CPUs are really fast, and the completely different trap frames would make these handlers really difficult to implement. pmap_changeprot() was only used by the clock and one other place; deprecate it. probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we can probe IO locations by physical addresses. Some pmap cleanup. Some more copyright cleanup.
1.9	05-Jun-1999	eeh	Make pbrobeget() and probeset() work for 64-bit values as well. To do this the arguments are changed so the address is first and the ASI second so we can have the address in %o0:%o1 and not worry about unused registers. Also a bit of copyright cleanup.
1.8	05-Jun-1999	eeh	Fix things up so they compile again.
1.7	30-May-1999	eeh	Add code to support using %tick as the system clock if no "counter-timer" node is found.
1.6	30-May-1999	mrg	clone intr.h from the SPARC.
1.5	24-Nov-1998	mrg	branches: 1.5.6; add protos for switchtoctx, fixalign and emulinstr. XXX should all these be here?
1.4	11-Nov-1998	thorpej	Changes to support fork_kthread(): - cpu_set_kpc() now takes void *arg third argument, passed to the entry point. - cpu_fork() allows parent to be non-curproc iff parent is proc0. When forking non-curproc, assume its state has already been saved. - Adjust various pieces of machine-dependent code to account of all of this.
1.3	05-Oct-1998	thorpej	cpu_set_kpc() prototype is already in <sys/systm.h>.
1.2	05-Sep-1998	eeh	It slices. It dices. It does everything except exec a sparc32_compat init.
1.1	20-Jun-1998	eeh	branches: 1.1.1; Initial revision

1.13.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.29.6.6	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

Shows who's waiting for which locks and what the owner is up to. Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>. And thus out of <sys/param.h>, which is exceedingly overused and fragile and delenda est. Should fix (some) issues with the recent inclusion of machine/lock.h in various machine/mutex.h files. arm/mutex.h: Need machine/intr.h, machine/lock.h. For ipl_cookie_t and __cpu_simple_lock_t. evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL. Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which should really be fixed. opencrypto/cryptodev.h: Fix includes. - Move sys/condvar.h under #ifdef _KERNEL. - Add some other necessary includes and forward declarations. - Sort. hp300/intr.h: Fix missing includes. linux/idr.h: Need <sys/mutex.h> for kmutex_t. amiga/intr.h: Don't define spl() functions if !_KERNEL. This is used by crash(8) now, and what's important is ipl_cookie_t. cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8). cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER. Probably not necessary but let's be a little more cautious about this. atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8). arm/cpu.h: Need sys/param.h for COHERENCY_UNIT. Nix machine/param.h -- not meant to be used directly, pulled in by sys/param.h. Move the definition of ipl_cookie_t out of the kernel-only sections, some _KMEMUSER applications need it. ddb: Cast pointer to uintptr_t first before db_expr_t. hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). news68k/intr.h: Fix includes. Put some definitions under _KERNEL. next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). sys/ksem.h: Hack around fstat(8) abuse of _KERNEL. sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). x68k/intr.h: Put functions under _KERNEL so crash(8) can use this. Make ipl_cookie_t visible for _KMEMUSER userland applications. fix editor mishap in previous Explicitly include <sys/mutex.h> for kmutex_t. Replace kmutex_t (which may be undefined here) with struct kmutex , suggested by Taylor. hp300/intr.h: Put most of this under #ifdef _KERNEL. Only ipl_cookie_t really needs to be exposed now, for crash(8). mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). Make inclusion of sys/intr.h explicit for spl. fix hppa and vax builds. machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in sys/types.h. avoids cpu_data.h vs sched.h include order issues. move the hppa ipl_t typedef with the moved usage of it. machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h. Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which always comes from sys/types.h. And, really, sys/types.h (or at least sys/stdint.h) is needed for uintN_t and uintptr_t. ddb: Cast pointer to uintptr_t, then to db_expr_t. Avoids warnings about conversion between pointer and integer of different size on some architectures. re-fix hppa builds. this file uses __cpu_simple_lock(), not just the underlying type, so it does need machine/lock.h. Break cycle by using `struct kmutex ' instead of `kmutex_t '. sys/sched.h included sys/mutex.h which includes sys/intr.h which includes machine/intr.h which on cats includes arm/footbridge/footbridge_intr.h which includes arm/cpu.h which includes sys/cpu_data.h which includes sys/sched.h But there was never any real need for sys/mutex.h in sys/sched.h, because it only uses pointers to the opaque struct kmutex. Cycle broken by using `struct kmutex *' instead of pulling in sys/mutex.h for the definition of kmutex_t. Side effect: This revealed that sys/cpu_data.h needed sys/intr.h (which was pulled in accidentally by sys/mutex.h via sys/sched.h) for SOFTINT_COUNT. Also revealed some other machine/cpu.h header files were missing includes of sys/mutex.h for kmutex_t. ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t. explicitly include no longer implicitly included sys/mutex.h. arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz. Sidesteps namespace collision with `#define bits ...' in net/zlib.c. complete the previous - there were two calls to find_first_bit() to fix. arm/xscale: Missed a spot with previous find_first_bit commit. evbarm/g42xxeb: Fix off-by-one in previous. The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x), which is equivalent to fls32(x) - 1, not to fls32(x). Note that fls32 is 1-based and returns 0 for x=0.

1.5	17-Oct-2007	garbled	branches: 1.5.16; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.5	13-Sep-2006	mrg	branches: 1.5.30; 1.5.36; 1.5.44; SMP cleanup. provide support for multiple CPUs in DDB. (SMP itself is still not working.) cpu.h: - add a pointer for DDB regs in SMP environment to struct cpu_info - remove the #defines for mp_pause_cpus() and mp_resume_cpus() cpuset.h: - remove CPUSET_ALL() and rename CPUSET_ALL_BUT() to CPUSET_EXCEPT() from petrov. db_machdep.h: - rename the members of db_regs_t to be the same as sparc - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - redo DDB_REGS to no longer be a pointer to a fixed data structure but to one allocated per-cpu when ddb is entered - move a bunch of prototypes in here intr.h: - remove SPARC64_IPI_ macros, no longer used db_interface.c: - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - make "nil" a 64 bit entity - change the ddb register access methods to work in multiprocessor environment, it is now very much like sparc does it - in kdb_trap() avoid accessing ddb_regp when it is NULL - update several messages to include the cpu number - unpause other cpus much later when resuming from ddb - rename db_lock() to db_lock_cmd(), as the sparc-like code has db_lock as a simple lock - remove "mach cpus" command, and replace it with "mach cpu" (which does the same) and also implement "mach cpu N" to switch to another cpus saved trapframe db_trace.c: - update for the ddb_regs -> ddb_regp change genassym.cf: - add TF_KSTACK as offsetof(struct trapframe64, tf_kstack) ipifuncs.c: - overhaul extensively - remove all normal interrupt handlers as IPI's, we now handle them all specially in locore.s:interrupt_vector - add a simplelock around all ipi functions - it's not safe for multiple cpus to be sending IPI's to each other right now - rename sparc64_ipi_pause() to sparc64_ipi_pause_thiscpu() and, if DDB is configured, enable it to save the passed-in trapframe to a db_regs_t for this cpu's saved DDB registers. - remove the "ipimask" system (SPARC64_IPI_ macros) and instead pass functions directly - in sparc64_send_ipi() always set the interrupt arguments to 0, the address and argument of the to be called function. (the argument right now is the address of ipi_tlb_args variable, and part of the reason why only one CPU can send IPI's at a time.) don't wait forever for an IPI to complete. some of this is from petrov. - rename sparc64_ipi_{halt,pause,resume}_cpus() to mp_{halt,pause,resume}_cpus() - new function mp_cpu_is_paused() used to avoid access missing saved DDB registers - actually broadcast the flush in smp_tlb_flush_pte(), smp_tlb_flush_ctx() and smp_tlb_flush_all(). the other end may not do anything yet in the pte/ctx cases yet... kgdb_machdep.c: - rework for changed member names in db_regs_t. locore.s: - shave an instruction from syscall_setup() (set + ld -> sethi + ld) - remove some old dead debug code - add new sparc64_ipi_halt IPI entry point, it just calls the C vector to shutdown. - add new sparc64_ipi_pause IPI entry point, which just traps into the debugger using the normal breakpoint trap. these cpus usually lose the race in db_interface.c:db_suspend_others() and end up calling the C vector sparc64_ipi_pause_thiscpu(). - add #if 0'ed code to sparc64_ipi_flush_{pte,ctx}() IPI entry points to call the sp_ version of these functions. - in rft_kernel (return from trap, kernel), check to see if the %tpc is at the sparc64_ipi_pause_trap_point and if so, call "done" not "retry" - rework cpu_switch slightly: save the passed-in lwp instead of using the one in curlwp - in cpu_loadproc(), save the new lwp not the old lwp, to curlwp - in cpu_initialize(), set %tl to zero as well. from petrov. - in cpu_exit(), fix a load register confusion. from petrov. - change some "set" in delay branch to "mov". machdep.c: - deal with function renames pmap.c: - remove a spurious space trap.c: - remove unused "trapstats" variable - add cpu number to a couple of messages

This avoids SIRs caused by double kernel_data_faults, caused by spills of obsolete user windows after the context for that user pmap is gone.
1.42	20-Feb-2006	cdi	branches: 1.42.18; 1.42.20; 1.42.24; 1.42.26; Use ANSI-style function definitions and declarations.
1.41	16-Feb-2006	perry	Change "inline" back to "__inline" in .h files -- C99 is still too new, and some apps compile things in C89 mode. C89 keywords stay. As per core@.
1.40	11-Feb-2006	cdi	ANSIfication: u_intN_t -> uintN_t, use ANSI function declarations/definitions instead of K&R ones.
1.39	24-Dec-2005	perry	branches: 1.39.2; 1.39.4; 1.39.6; __asm__ -> __asm __const__ -> const __inline__ -> inline __volatile__ -> volatile
1.38	24-Dec-2005	perry	Remove leading __ from __(const\|inline\|signed\|volatile) -- it is obsolete.
1.37	11-Dec-2005	christos	merge ktrace-lwp.
1.36	01-Jul-2004	petrov	branches: 1.36.12; Added UPA_MID definitions and macros(similar to FreeBSD). Added membar_store, membar_load macros. No need to set %asi _after_ alternate space use in corresponding functions. Enable(unifdef) casa functions for __arch64__.
1.35	01-Jul-2004	heas	typo in define name, littie -> little
1.34	24-Jun-2004	martin	Add missing ; in inline assembler for 32bit kernels
1.33	17-Jun-2004	petrov	clean-up, reformat __asm statements.
1.32	22-Mar-2004	nakayama	Eliminate cast 64-bit address to u_long.
1.31	14-Mar-2004	chs	checkpoint of MP work from dennis and myself. includes cross-processor interrupt framework, a sledgehammer TLB invalidation and misc MP fixes. doesn't work at all yet.
1.30	24-Apr-2002	eeh	branches: 1.30.10; Don't need to flush the d$ for MMU bypass accesses.
1.29	14-Jan-2002	eeh	Make PHYS_ASI() also recognize little-endian ASIs.
1.28	06-Aug-2001	eeh	branches: 1.28.6; Add some alternate spellings for ASIs. Make sure ASI_PRIMARY_NOFAULT is always restored. Garbage collect some old code.
1.27	19-Jul-2001	eeh	Don't bother flushing cache lines for un-cached accesses.
1.26	29-Jun-2001	eeh	branches: 1.26.2; Add the shorter version of block ASIs used by Sun.
1.25	29-Dec-2000	eeh	Fix some 32-bit assembly code.
1.24	04-Dec-2000	fvdl	Comment out caxsa, it's not used. Avoids 32 bit compile errors.
1.23	31-Aug-2000	eeh	Fix register sheduling bug in st?a() routines and add casxa().
1.22	14-Jul-2000	eeh	Tell gcc that stores clobber "memory". Probably makes no difference since they should not be used to access normal memory anyway.
1.21	24-Jun-2000	eeh	With these changes the kernel seems almost stable again.
1.20	24-Jun-2000	eeh	More VM cleanup: Move the cpu_info structure above the interrupt stack so it won't get corrupted if the stack overflows. Flush the D$ before and after all MMU bypass accesses since the D$ latches all of those.
1.19	20-Jun-2000	eeh	lda is unsigned, ldswa is signed. Fixes a 32-bit sign extension bug.
1.18	19-Jun-2000	eeh	branches: 1.18.2; Have separate data and text segments, make text read-only.
1.17	10-Jun-2000	eeh	Only use 32-bit addresses for all accesses that don't bypass the MMU. Makes SBus work again.

1.15	07-Jun-2000	pk	Add a couple of missing semi-colons.
1.14	02-Jun-2000	eeh	Use all 64 address bits in lda()/sta() macros so physical device addresses work. (Also add some bus_space_*() debug hooks).
1.13	10-Apr-2000	mrg	branches: 1.13.2; - IRSR_BUSY is bit 5 not bit 4. - IRSR_MID(x) is &'d with 0x1f (5 bits) not 0xf.
1.12	08-Jun-1999	mrg	branches: 1.12.2; mmm, missing return types make gcc unhappy.
1.11	05-Jun-1999	eeh	Make pbrobeget() and probeset() work for 64-bit values as well. To do this the arguments are changed so the address is first and the ASI second so we can have the address in %o0:%o1 and not worry about unused registers. Also a bit of copyright cleanup.
1.10	31-May-1999	eeh	Fix some bugs in some more of those asm macros.
1.9	30-May-1999	eeh	Re-write ASI load/stores to use full 64-bit addresses so we can use device register addresses with MMU bypass ASIs.
1.8	22-May-1999	eeh	Fixup argument confusion to __asm() statements. long long is two registers wide in 32-bit mode. Doh!.
1.7	11-May-1999	eeh	Don't clobber any input regs in __asm statements.
1.6	22-Mar-1999	eeh	branches: 1.6.4; Flush D$ on bypass accesses.

1.4	13-Nov-1998	eeh	Fix 32-bit gcc scheduling problems.
1.3	05-Sep-1998	eeh	It slices. It dices. It does everything except exec a sparc32_compat init.

1.36	10-Mar-2020	christos	Don't provide things that don't make sense in userland. We don't provide access to registers crash(8)...
1.35	06-Nov-2017	christos	branches: 1.35.4; Cleanup and clarify the ELFSIZE mess: We now have 2 variables automatically set in elf_machdep.h: ARCH_ELFSIZE: the size for userland binaries KERN_ELFSIZE: the size for the kernel binaries DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the same values DB_ELFSIZE used to have. In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE for the kernel and ARCH_ELFSIZE for userland. These defaults should eliminate the need for most manual ELFSIZE setting.
1.34	31-Oct-2015	nakayama	Remove #define SUN4U since machine/frame.h doesn't check SUN4U anymore.
1.33	12-Jul-2011	mrg	branches: 1.33.12; 1.33.30; rename sparc64 BLOCK_SIZE and BLOCK_ALIGN to have SPARC64_ prefixes. for the assembler files, define the old names to the new names since using the new names cause ugliness due to longer identifer names, and reduces churn. fixes build issues in dtv and vaguely makes <machine/psl.h> slightly less name-space invasive.
1.32	20-Jun-2011	nakayama	Remove frame32 hack with using the same trick in netbsd32_machdep.c.
1.31	27-May-2011	nakayama	branches: 1.31.2; Fix 32-bit kernel build.
1.30	26-May-2011	joerg	Introduce DDB_EXPR_FMT and replace the logic around DB_EXPR_T_IS_QUAD.

1.27	14-Jan-2011	rmind	branches: 1.27.2; Retire struct user, remove sys/user.h inclusions. Note sys/user.h header as obsolete. Remove USER_TO_UAREA/UAREA_TO_USER macros. Various #include fixes and review by matt@.
1.26	25-Nov-2008	nakayama	branches: 1.26.8; Make DDB shows right register values on 32-bit sparc64 kernels. - define db_expr_t as int64_t. - %gsr is 32-bit, so use db_sparc_intop. - sync arguments with function prototype. - ansify.
1.25	10-Jul-2008	nakayama	branches: 1.25.2; 1.25.4; sparc64_ipi_save_fpstate: - use primary MMU context for consistency with other trap/interrupt handlers. sparc64_ipi_save_fpstate, savefpstate: - avoid storing fp registers as we can. sparc64_ipi_save_fpstate, savefpstate, loadfpstate: - remove unaligned case since buffers allocated with pool_cache are ensured 64-byte aligned. Ok by martin@.
1.24	29-Feb-2008	martin	branches: 1.24.4; 1.24.6; 1.24.8; 1.24.10; Rearange ddb saved register values slightly. While there fix completely bogus register access ops for < 64 bit values.
1.23	22-Feb-2007	matt	branches: 1.23.22; 1.23.38; 1.23.42; More boolean_t -> bool
1.22	21-Feb-2007	thorpej	Replace the Mach-derived boolean_t type with the C99 bool type. A future commit will replace use of TRUE and FALSE with true and false.
1.21	07-Oct-2006	rjs	branches: 1.21.4; Allow kernel to build with KGDB enabled.
1.20	13-Sep-2006	mrg	branches: 1.20.2; SMP cleanup. provide support for multiple CPUs in DDB. (SMP itself is still not working.) cpu.h: - add a pointer for DDB regs in SMP environment to struct cpu_info - remove the #defines for mp_pause_cpus() and mp_resume_cpus() cpuset.h: - remove CPUSET_ALL() and rename CPUSET_ALL_BUT() to CPUSET_EXCEPT() from petrov. db_machdep.h: - rename the members of db_regs_t to be the same as sparc - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - redo DDB_REGS to no longer be a pointer to a fixed data structure but to one allocated per-cpu when ddb is entered - move a bunch of prototypes in here intr.h: - remove SPARC64_IPI_ macros, no longer used db_interface.c: - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - make "nil" a 64 bit entity - change the ddb register access methods to work in multiprocessor environment, it is now very much like sparc does it - in kdb_trap() avoid accessing ddb_regp when it is NULL - update several messages to include the cpu number - unpause other cpus much later when resuming from ddb - rename db_lock() to db_lock_cmd(), as the sparc-like code has db_lock as a simple lock - remove "mach cpus" command, and replace it with "mach cpu" (which does the same) and also implement "mach cpu N" to switch to another cpus saved trapframe db_trace.c: - update for the ddb_regs -> ddb_regp change genassym.cf: - add TF_KSTACK as offsetof(struct trapframe64, tf_kstack) ipifuncs.c: - overhaul extensively - remove all normal interrupt handlers as IPI's, we now handle them all specially in locore.s:interrupt_vector - add a simplelock around all ipi functions - it's not safe for multiple cpus to be sending IPI's to each other right now - rename sparc64_ipi_pause() to sparc64_ipi_pause_thiscpu() and, if DDB is configured, enable it to save the passed-in trapframe to a db_regs_t for this cpu's saved DDB registers. - remove the "ipimask" system (SPARC64_IPI_ macros) and instead pass functions directly - in sparc64_send_ipi() always set the interrupt arguments to 0, the address and argument of the to be called function. (the argument right now is the address of ipi_tlb_args variable, and part of the reason why only one CPU can send IPI's at a time.) don't wait forever for an IPI to complete. some of this is from petrov. - rename sparc64_ipi_{halt,pause,resume}_cpus() to mp_{halt,pause,resume}_cpus() - new function mp_cpu_is_paused() used to avoid access missing saved DDB registers - actually broadcast the flush in smp_tlb_flush_pte(), smp_tlb_flush_ctx() and smp_tlb_flush_all(). the other end may not do anything yet in the pte/ctx cases yet... kgdb_machdep.c: - rework for changed member names in db_regs_t. locore.s: - shave an instruction from syscall_setup() (set + ld -> sethi + ld) - remove some old dead debug code - add new sparc64_ipi_halt IPI entry point, it just calls the C vector to shutdown. - add new sparc64_ipi_pause IPI entry point, which just traps into the debugger using the normal breakpoint trap. these cpus usually lose the race in db_interface.c:db_suspend_others() and end up calling the C vector sparc64_ipi_pause_thiscpu(). - add #if 0'ed code to sparc64_ipi_flush_{pte,ctx}() IPI entry points to call the sp_ version of these functions. - in rft_kernel (return from trap, kernel), check to see if the %tpc is at the sparc64_ipi_pause_trap_point and if so, call "done" not "retry" - rework cpu_switch slightly: save the passed-in lwp instead of using the one in curlwp - in cpu_loadproc(), save the new lwp not the old lwp, to curlwp - in cpu_initialize(), set %tl to zero as well. from petrov. - in cpu_exit(), fix a load register confusion. from petrov. - change some "set" in delay branch to "mov". machdep.c: - deal with function renames pmap.c: - remove a spurious space trap.c: - remove unused "trapstats" variable - add cpu number to a couple of messages

1.15	18-May-2003	martin	branches: 1.15.2; My reading of the gdb code seems to indicate it expects 125 registers from sparc64, not 72 (sparc value). Bump kgdb buffer size a bit too.
1.14	29-Apr-2003	scw	Add a BKPT_ADDR() macro which gives MD code a chance to munge a breakpoint address before it's used. Currently a no-op on all but sh5. This is useful on sh5, for example, to mask off the instruction type encoding in the bottom two address bits, and makes it possible to do "db> break $rXX" instead of manually munging the address.

1.3	12-Jun-2005	dyoung	Make disklabel(8) and fdisk(8) into "host tools " last step: build and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel, ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/. To avoid clashes with a build-host's header files, especially on *BSD, the host-tools versions of fdisk and disklabel search for #includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h, and bootinfo.h in a new #includes namespace, nbinclude/. That is, they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>, <nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and such. I have also updated the system headers to #include from nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
1.2	20-Jul-2002	mrg	branches: 1.2.6; use <sparc/foo.h> where appropriate. now these files become very very difficult to get out of sync. add bootinfo.h and promlib.h (using the same method) so that sparc64 headers can build sparc stand (not yet finished.)

1.14	06-Nov-2017	christos	Cleanup and clarify the ELFSIZE mess: We now have 2 variables automatically set in elf_machdep.h: ARCH_ELFSIZE: the size for userland binaries KERN_ELFSIZE: the size for the kernel binaries DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the same values DB_ELFSIZE used to have. In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE for the kernel and ARCH_ELFSIZE for userland. These defaults should eliminate the need for most manual ELFSIZE setting.
1.13	12-Aug-2017	joerg	Add sparc/sparc64 support for irelative relocations.
1.12	31-Jan-2017	martin	PR port-sparc64/51925: remove EM_SPARC32PLUS from the 64 bit ELF machine ids we accept for our executables - that combination makes no sense at all (probably copy&pasto).
1.11	14-Nov-2013	martin	branches: 1.11.6; 1.11.10; 1.11.14; Allow TOPDOWN-VM only for binaries compiled with appropriate code model. No change yet, as __HAVE_TOPDOWN is not yet defined.

1.6	16-Mar-2000	mycroft	Foolish consistency. Mainly, always use underscores and sys/endian.h.
1.5	21-Aug-1999	simonb	branches: 1.5.2; Include <sys/endian.h> after defining whether where are little- or big-endian. i386, pc532 and vax still include <machine/byte_swap.h> and define macros for the {n,h}to{h,n}*() functions. mips also defines some endian-independent assembly-code aliases for unaligned memory accesses.
1.4	24-Jan-1999	mycroft	Mark [hn]to[nh][ls]() with __const__, so they are subject to CSE.
1.3	15-Jan-1999	bouyer	Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.

1.27	01-Feb-2010	mrg	branches: 1.27.2; - add a PDB_CTX_FLUSHALL debug type to pmap.c, and also log the cpu_number() in a bunch more cases - make sparc64_ipi_halt_thiscpu() and sparc64_ipi_pause_thiscpu() return void, their callers never checked anyway. - remove prototypes for sparc64_ipi_flush_ctx() and sparc64_ipi_flush_all(), there are no such functions
1.26	30-Nov-2009	nakayama	sparc64_ipi_flush_ctx and sparc64_ipi_flush_all have been removed, so remove its event counters as well.
1.25	28-Apr-2008	martin	Remove clause 3 and 4 from TNF licenses
1.24	22-Apr-2008	nakayama	branches: 1.24.2; #include "opt_multiprocessor.h" #include <machine/psl.h> Make sparc64 kernel build again.
1.23	14-Apr-2008	nakayama	branches: 1.23.2; Remove sparc64_ipi_sync_tick. Since we can use counter-timer as timecounter instead of %tick on SMP kernel, it is not necessary to sync all CPUs %tick registers.
1.22	14-Mar-2008	nakayama	Improve IPI handling: - make IPI takes two arguments. - add IPI event counters per-CPU. - implement IPI functions which were missing or broken. - insert DELAY while halting primary CPU in IPI handler.
1.21	02-Mar-2008	martin	Make ddb's "mach cpu" command do the right thing: run ddb on the requested cpu. There is a tiny bit of cheating involved, but I assume we won't run parallel + recursive ddb scripts to play towers of hanoi. This fixes the wrong prompt, and (more importantly) makes things like "mach dtlb" display the registers of the right MMU.
1.20	15-Jan-2008	martin	branches: 1.20.2; 1.20.6; Rename cpuset_t for now to sparc64_cpuset_t, to avoid a name clash with <sys/pset.h>. Mid-term we should probably convert to the MI cpuset_t.
1.19	03-Dec-2007	ad	branches: 1.19.6; Interrupt handling changes, in discussion since February: - Reduce available SPL levels for hardware devices to none, vm, sched, high. - Acquire kernel_lock only for interrupts at IPL_VM. - Implement threaded soft interrupts.
1.18	17-Oct-2007	garbled	branches: 1.18.2; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.17	17-May-2007	yamt	branches: 1.17.8; 1.17.10; merge yamt-idlelwp branch. asked by core@. some ports still needs work. from doc/BRANCHES: idle lwp, and some changes depending on it. 1. separate context switching and thread scheduling. (cf. gmcgarry_ctxsw) 2. implement idle lwp. 3. clean up related MD/MI interfaces. 4. make scheduler(s) modular.
1.16	06-Oct-2006	jnemeth	branches: 1.16.4; 1.16.8; 1.16.10; 1.16.16; Initial support for floppy drives on sparc64. This has been tested on an Ultra 2 and works fine, apart from formatting which is known to be broken. It failed to work on an ebus machine. The ebus support compiles fine, but I don't have hardware for testing. This code is based on the sparc driver with hints from OpenBSD on how to do the sbus and ebus attachments, along with help from martin@ and mrg@. Initial commit approved by martin@ TODO: - fix ebus support - fix XXX issues - check resource deallocation - fix formatting - merge remaining differences from sparc driver - split out back end chip support - have sparc driver use new common back end chip support - adapt to newlock when branch is ready - adapt to "disk-info" property dictionary
1.15	18-Sep-2006	martin	branches: 1.15.2; Lazy FPU handling for the MULTIPROCESSOR case
1.14	13-Sep-2006	mrg	SMP cleanup. provide support for multiple CPUs in DDB. (SMP itself is still not working.) cpu.h: - add a pointer for DDB regs in SMP environment to struct cpu_info - remove the #defines for mp_pause_cpus() and mp_resume_cpus() cpuset.h: - remove CPUSET_ALL() and rename CPUSET_ALL_BUT() to CPUSET_EXCEPT() from petrov. db_machdep.h: - rename the members of db_regs_t to be the same as sparc - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - redo DDB_REGS to no longer be a pointer to a fixed data structure but to one allocated per-cpu when ddb is entered - move a bunch of prototypes in here intr.h: - remove SPARC64_IPI_ macros, no longer used db_interface.c: - change "db_regs_t ddb_regs" to "db_regs_t ddb_regp" and change all references to suit - make "nil" a 64 bit entity - change the ddb register access methods to work in multiprocessor environment, it is now very much like sparc does it - in kdb_trap() avoid accessing ddb_regp when it is NULL - update several messages to include the cpu number - unpause other cpus much later when resuming from ddb - rename db_lock() to db_lock_cmd(), as the sparc-like code has db_lock as a simple lock - remove "mach cpus" command, and replace it with "mach cpu" (which does the same) and also implement "mach cpu N" to switch to another cpus saved trapframe db_trace.c: - update for the ddb_regs -> ddb_regp change genassym.cf: - add TF_KSTACK as offsetof(struct trapframe64, tf_kstack) ipifuncs.c: - overhaul extensively - remove all normal interrupt handlers as IPI's, we now handle them all specially in locore.s:interrupt_vector - add a simplelock around all ipi functions - it's not safe for multiple cpus to be sending IPI's to each other right now - rename sparc64_ipi_pause() to sparc64_ipi_pause_thiscpu() and, if DDB is configured, enable it to save the passed-in trapframe to a db_regs_t for this cpu's saved DDB registers. - remove the "ipimask" system (SPARC64_IPI_ macros) and instead pass functions directly - in sparc64_send_ipi() always set the interrupt arguments to 0, the address and argument of the to be called function. (the argument right now is the address of ipi_tlb_args variable, and part of the reason why only one CPU can send IPI's at a time.) don't wait forever for an IPI to complete. some of this is from petrov. - rename sparc64_ipi_{halt,pause,resume}_cpus() to mp_{halt,pause,resume}_cpus() - new function mp_cpu_is_paused() used to avoid access missing saved DDB registers - actually broadcast the flush in smp_tlb_flush_pte(), smp_tlb_flush_ctx() and smp_tlb_flush_all(). the other end may not do anything yet in the pte/ctx cases yet... kgdb_machdep.c: - rework for changed member names in db_regs_t. locore.s: - shave an instruction from syscall_setup() (set + ld -> sethi + ld) - remove some old dead debug code - add new sparc64_ipi_halt IPI entry point, it just calls the C vector to shutdown. - add new sparc64_ipi_pause IPI entry point, which just traps into the debugger using the normal breakpoint trap. these cpus usually lose the race in db_interface.c:db_suspend_others() and end up calling the C vector sparc64_ipi_pause_thiscpu(). - add #if 0'ed code to sparc64_ipi_flush_{pte,ctx}() IPI entry points to call the sp_ version of these functions. - in rft_kernel (return from trap, kernel), check to see if the %tpc is at the sparc64_ipi_pause_trap_point and if so, call "done" not "retry" - rework cpu_switch slightly: save the passed-in lwp instead of using the one in curlwp - in cpu_loadproc(), save the new lwp not the old lwp, to curlwp - in cpu_initialize(), set %tl to zero as well. from petrov. - in cpu_exit(), fix a load register confusion. from petrov. - change some "set" in delay branch to "mov". machdep.c: - deal with function renames pmap.c: - remove a spurious space trap.c: - remove unused "trapstats" variable - add cpu number to a couple of messages

for pthreads. port-sparc64/37534 - ktrace firefox gives kernel trap 30: data access expection GDB changes: - delete gdb53 - enable gdb6 on all architectures - add support for amd64 crash dumps - add support for sparc64 crash dumps - add support for /proc pid to executable filename for all archs - enable thread support for all architectures - add a note section to kernels to all platforms - support detection/unwinding of signals for most architectures. - Fix PTHREAD_UCONTEXT_TO_REG / PTHREAD_REG_TO_UCONTEXT on sh3. - Apply fix from binutils-current so that sparc gdb can be cross built on a 64bit host. SA/pthread changes: Pre-allocate memory needed for event delivery. Eliminates dropped interrupts under load. Deliver intra-process signals to running threads Eliminate some deadlock scenarios Fix intra-process signal delivery when delivering to a thread waiting for signals. Makes afs work again!
1.4.76.1	01-Feb-2008	riz	Pull up following revision(s) (requested by martin in ticket #983): sys/arch/sparc64/include/kcore.h: revision 1.5 lib/libkvm/kvm_sparc64.c: revision 1.11 sys/arch/sparc64/sparc64/pmap.c: revision 1.201 Extend the sparc64 cpu kcore segment so that it records all kernel mappings done via locked 4 MB pages. The old format could only record physically continous kernel text mappings. For compatibility reasons, just extend the structure and fill in all the old fields as well. Use the new sparc64 kcore cpu segment extensions to properly map VA/PAs on kernels with more then 4 MB text/rodata segment.

1.10	20-Jul-2002	mrg	use <sparc/foo.h> where appropriate. now these files become very very difficult to get out of sync. add bootinfo.h and promlib.h (using the same method) so that sparc64 headers can build sparc stand (not yet finished.)
1.9	03-May-2002	thorpej	branches: 1.9.2; Don't define _LP64 here.
1.8	08-Aug-2000	tshiozak	branches: 1.8.4; 1.8.8; Preparation for the future introduction of multibyte locale. - MB_LEN_MAX is increased to 32. - To ensure binary compatibility for old executables under multibyte locale, versioned setlocale is added. - __mb_len_cur definision is added in setlocale.c and enable it in stdlib.h . It is also important for multibyte locale stuffs, but I just forgot.
1.7	07-Mar-2000	kleink	branches: 1.7.2; 1.7.4; Define ISO C99 (unsigned) long long (min, max) symbols.

1.5	31-Jan-1999	mrg	branches: 1.5.8; 1.5.14; retire _LP64; use compiler provided __arch64__, but still defined _LP64 where we used to anyway.
1.4	08-Oct-1998	eeh	Fix more syscall32 and signal breakage.
1.3	11-Sep-1998	eeh	Add support for 64-bit types if _LP64 is defined.

1.5.14.1	27-Dec-1999	wrstuden	Pull up to last week's -current.
1.5.8.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.3	28-Apr-2008	martin	branches: 1.3.44; 1.3.60; Remove clause 3 and 4 from TNF licenses
1.2	27-Jan-2006	cdi	branches: 1.2.72; 1.2.74; 1.2.76; Alter sparc64 bootstrap, catch up to ofwboot v1.9: - Accept bootinfo structure passed down from ofwboot v1.9 - Drop kernel re-mapping code - Use permanent 4MB mappings provided by the loader instead - Change kernel entry address to point directly at the code instead of pointing at the trap table's first slot. This allows the bootloader to detect those kernels which are aware of the new boot scheme - Due to the changes in kernel mapping code, alter secondary CPU bootstrap code to use trampoline just like FreeBSD does (some FreeBSD code is used here as well)
1.1	16-Aug-2000	mrg	branches: 1.1.2; 1.1.4; 1.1.44; 1.1.56; include the sparc loadfile_machdep.h as-is; we can blow this header away completely later.

1.6	01-May-2000	thorpej	Fix a declaration inside __ldstub().
1.5	29-Apr-2000	thorpej	Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files are also required to supply inline functions __cpu_simple_lock(), __cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be supported on that platform (i.e. if MULTIPROCESSOR is defined in the _KERNEL case). Change these functions to take an int * (&alp->lock_data) rather than the struct simplelock * itself. These changes make it possible for userland to use the locking primitives by including <machine/lock.h>.

N.B. Need to decide what to do with sparc64/sparc64/asm.h which has name conflicts with sparc64/include/asm.h. So far most of sparc64/sparc64/asm.h has been moved to ctlreg.h.

1.11	18-May-2024	thorpej	Clean up the <sys/ucontext.h> <-> <machine/mcontext.h> interface up a little: - Define _UC_MD_BIT* constants for the available machine-dependent bits, and use those constants to define the machine-dependent bits as well as the machine-independent bits that have machine-dependent values. - Explicitly generate an error if _UC_TLSBASE, _UC_SETSTACK, or _UC_CLRSTACK are not defined by <machine/mcontext.h>.
1.10	19-Feb-2018	mrg	fix _UC_MACHINE32_FP() -- use 32 bit pointer value so that [15] is the right offset. do this by using __greg32_t, which is only in the sparc64 version, and these are only useful there, so move them.
1.9	12-Sep-2012	manu	branches: 1.9.32; setcontext() used to be incompatible with -lpthread since it affected the TLS pointer, therefore wrecking the pthread environement. Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha) that controlled whether setcontext() would change the TLS pointer. This change let libpthread override setcontext() with its own version that unsets _UC_TLSBASE, enabling safe usage of setcontext() with -lpthread. We also have the following required changes here: - rename alpha's _UC_UNIQUE into _UC_TLSBASE - add _UC_TLSBASE definition in header file for all ports (powerpc, sh3, sparc and sparc64 lack the implementation for now) - introduce a libc stub that can be overriden for setcontext() - modify MD libcs swapcontext() implementations so that they use the setcontext() libc stub instead of doing a plain system call. While we are there: - document various MD _UC_* flags in header file - add libc and libpthread tests for swapcontext() behavior (hopefully helpful to spot MD problems introduced with this change) Future work: - Deciding whether kernel support or _UC_TLSBASE should be added for powerpc, sh3, sparc and sparc64 is left to portmasters sparc64 Approved by core@

Don't rely on this interface as a compiler might strip frame pointer or optimize it making this interface unreliable. For hppa assume a small frame context, for larger frames FP might be located in a different register (4 instead of 3). For ia64 there is no strict frame pointer, and registers might rotate. Reuse 79 following: ./gcc/config/ia64/ia64.h:#define HARD_FRAME_POINTER_REGNUM LOC_REG (79) Once ia64 will mature, this should be revisited. A macro can encapsulate a real function for extracting Frame Pointer on more complex CPUs / ABIs. For the remaining CPUs, reuse standard register as defined in appropriate ABI. The direct users of this macro are LLVM and GCC with Sanitizers. Proposed on tech-userlevel@.

Shows who's waiting for which locks and what the owner is up to. Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>. And thus out of <sys/param.h>, which is exceedingly overused and fragile and delenda est. Should fix (some) issues with the recent inclusion of machine/lock.h in various machine/mutex.h files. arm/mutex.h: Need machine/intr.h, machine/lock.h. For ipl_cookie_t and __cpu_simple_lock_t. evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL. Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which should really be fixed. opencrypto/cryptodev.h: Fix includes. - Move sys/condvar.h under #ifdef _KERNEL. - Add some other necessary includes and forward declarations. - Sort. hp300/intr.h: Fix missing includes. linux/idr.h: Need <sys/mutex.h> for kmutex_t. amiga/intr.h: Don't define spl() functions if !_KERNEL. This is used by crash(8) now, and what's important is ipl_cookie_t. cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8). cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER. Probably not necessary but let's be a little more cautious about this. atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8). arm/cpu.h: Need sys/param.h for COHERENCY_UNIT. Nix machine/param.h -- not meant to be used directly, pulled in by sys/param.h. Move the definition of ipl_cookie_t out of the kernel-only sections, some _KMEMUSER applications need it. ddb: Cast pointer to uintptr_t first before db_expr_t. hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). news68k/intr.h: Fix includes. Put some definitions under _KERNEL. next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). sys/ksem.h: Hack around fstat(8) abuse of _KERNEL. sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). x68k/intr.h: Put functions under _KERNEL so crash(8) can use this. Make ipl_cookie_t visible for _KMEMUSER userland applications. fix editor mishap in previous Explicitly include <sys/mutex.h> for kmutex_t. Replace kmutex_t (which may be undefined here) with struct kmutex , suggested by Taylor. hp300/intr.h: Put most of this under #ifdef _KERNEL. Only ipl_cookie_t really needs to be exposed now, for crash(8). mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). Make inclusion of sys/intr.h explicit for spl. fix hppa and vax builds. machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in sys/types.h. avoids cpu_data.h vs sched.h include order issues. move the hppa ipl_t typedef with the moved usage of it. machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h. Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which always comes from sys/types.h. And, really, sys/types.h (or at least sys/stdint.h) is needed for uintN_t and uintptr_t. ddb: Cast pointer to uintptr_t, then to db_expr_t. Avoids warnings about conversion between pointer and integer of different size on some architectures. re-fix hppa builds. this file uses __cpu_simple_lock(), not just the underlying type, so it does need machine/lock.h. Break cycle by using `struct kmutex ' instead of `kmutex_t '. sys/sched.h included sys/mutex.h which includes sys/intr.h which includes machine/intr.h which on cats includes arm/footbridge/footbridge_intr.h which includes arm/cpu.h which includes sys/cpu_data.h which includes sys/sched.h But there was never any real need for sys/mutex.h in sys/sched.h, because it only uses pointers to the opaque struct kmutex. Cycle broken by using `struct kmutex *' instead of pulling in sys/mutex.h for the definition of kmutex_t. Side effect: This revealed that sys/cpu_data.h needed sys/intr.h (which was pulled in accidentally by sys/mutex.h via sys/sched.h) for SOFTINT_COUNT. Also revealed some other machine/cpu.h header files were missing includes of sys/mutex.h for kmutex_t. ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t. explicitly include no longer implicitly included sys/mutex.h. arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz. Sidesteps namespace collision with `#define bits ...' in net/zlib.c. complete the previous - there were two calls to find_first_bit() to fix. arm/xscale: Missed a spot with previous find_first_bit commit. evbarm/g42xxeb: Fix off-by-one in previous. The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x), which is equivalent to fls32(x) - 1, not to fls32(x). Note that fls32 is 1-based and returns 0 for x=0.
1.1	19-Mar-2002	thorpej	branches: 1.1.2; file mutex_impl.h was initially added on branch newlock.
1.1.2.5	22-Mar-2002	thorpej	Wrap the stuff that manipulates the guts of a mutex in __MUTEX_PRIVATE.
1.1.2.4	22-Mar-2002	thorpej	Add debug info structures if MUTEX_DEBUG or RWLOCK_DEBUG is defined. XXX Revisit, so that the structure doesn't change when debugging is turned on; do it out-of-band?
1.1.2.3	20-Mar-2002	thorpej	mtx_dummy needs to be unsigned.
1.1.2.2	19-Mar-2002	thorpej	Shuffle the mutex structure around and change types such that the mutex now 8 bytes instead of 16. Note we need a different layout for LP64 vs ILP32, since we want one particular field to overlap with the LSB of the "mtx_owner" field.
1.1.2.1	19-Mar-2002	thorpej	First draft of mutex and rwlock implementation for sparc64.
1.29	19-Oct-2016	skrll	PR kern/51514: ptrace(2) fails for 32-bit process on 64-bit kernel Updated from the original patch in the PR by me.
1.28	04-Jan-2014	dsl	branches: 1.28.6; 1.28.10; Remove __HAVE_PROCESS_XFPREGS and add the extra parameter for the size of the fp save area to all the process_read_fpregs() and process_write_fpregs() functions. None of the functions have been modified to use the new parameters. The size is set for all the writes, but some of the arch-specific reads just pass NULL. The amd64 (and i386) need variable sized fp register save areas in order to support AVX and other enhanced register areas. These functions are rarely called - so the extra argument won't matter.
1.27	29-May-2008	mrg	branches: 1.27.32; 1.27.42; 1.27.48; remove clause #3 from my license where there are no other copyright holders involved.
1.26	27-Jan-2008	dsl	branches: 1.26.6; 1.26.8; 1.26.10; 1.26.12; Remove NETBSD32_OFF_T_RETURN() netbsd32_lseek() now uses MI code to return all 64 bits of the new position.
1.25	17-Oct-2007	garbled	branches: 1.25.2; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.24	16-Sep-2007	dsl	Fix previous, 'long long' is 8 byte aligned on sparc32
1.23	16-Sep-2007	dsl	Define netbsd32_uint64 for 64bit integers with the alignment requirement of the corresponding 32bit architecture. Use it for the 64bit items in netbsd32_statvfs so that the structure doesn't collect 8byte alignment (and 4 bytes of trailing padding). This replaces the 'packed' attribute which wasn't architecture specific and would cause massive overheads accessing every member of sparc64. Should allow the MIPS64 port do DTRT.
1.22	16-Mar-2007	dsl	branches: 1.22.4; 1.22.12; 1.22.14; Use NETBSD32PTR64() and NETBSD32PTR32() throughout.
1.21	14-Mar-2006	cube	branches: 1.21.16; 1.21.20; 1.21.22; 1.21.24; Add the sparc64 MD bits to get usable coredumps for COMPAT_NETBSD32 binaries.
1.20	11-Feb-2006	cdi	branches: 1.20.2; 1.20.4; ANSIfication: u_intN_t -> uintN_t, use ANSI function declarations/definitions instead of K&R ones.
1.19	11-Dec-2005	christos	branches: 1.19.2; 1.19.4; 1.19.6; merge ktrace-lwp.
1.18	27-Sep-2005	chs	remove unnecessary includes.
1.17	12-Jul-2005	martin	When returning 64bit values (from netbsd32_lseek) fix up the return value vector (of 32bit values, most likely) via a MD macro.
1.16	20-Feb-2004	drochner	branches: 1.16.16; provide a definition NETBSD32_MID_MACHINE which tells for the a.out MID to look for in 32-bit emulation
1.15	26-Sep-2003	christos	move MI stuff to the MI include
1.14	29-Jun-2003	fvdl	branches: 1.14.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.13	29-Jun-2003	martin	struct proc * -> struct lwp *
1.12	16-Apr-2003	dsl	change 'data' arg of fo_ioctl to void * to match file.h
1.11	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.10	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.9	04-Jul-2002	thorpej	Add kernel support for having userland provide the signal trampoline: * struct sigacts gets a new sigact_sigdesc structure, which has the sigaction and the trampoline/version. Version 0 means "legacy kernel provided trampoline". Other versions are coordinated with machine- dependent code in libc. * sigaction1() grows two more arguments -- the trampoline pointer and the trampoline version. * A new __sigaction_sigtramp() system call is provided to register a trampoline along with a signal handler. * The handler is no longer passed to sensig() functions. Instead, sendsig() looks up the handler by peeking in the sigacts for the process getting the signal (since it has to look in there for the trampoline anyway). * Native sendsig() functions now select the appropriate trampoline and its arguments based on the trampoline version in the sigacts. Changes to libc to use the new facility will be checked in later. Kernel version not bumped; we will ride the 1.6C bump made recently.

1.5	02-Sep-1998	eeh	Periodic update: now starts probing devices.
1.4	27-Aug-1998	eeh	Add 64-bit pmap support: Moved from a two level 512/1024 entry setup mapping 32 (9/10/13) bits respectively to a three level 1024/1024/1024 entry setup mapping 43 (10/10/10/13) bits. In 32-bit mode we waste about 1/12 pages mapping the high 11 bits. We also only manage 43 of the possible 44 bits of virtual address space, wasting half of it. Oh well, maybe we'll do better next revision.
1.3	13-Aug-1998	eeh	Merge paddr_t changes into the main branch.
1.2	07-Jul-1998	eeh	branches: 1.2.2; General update: Added genassym.cf Removed lderr which should never have gotten in Removed lots of dead code from locore.s Added some softint stuff to intr.c Added support for halt -p esp and le both use bus_dmamap_*() functions now instead of kdvma_mapin() groundwork for PCI (but we still have no drivers for any sun4u PCI devices)

1.62	31-May-2021	simonb	branches: 1.62.18; Include "opt_param.h" (ifdef _KERNEL_OPT) everywhere that MSGBUFSIZE is referenced since some sources include <machine/param.h>.
1.61	28-Sep-2019	christos	branches: 1.61.12; remove local version of mstohz() now that <sys/param.h> provides it.
1.60	15-May-2019	christos	From: Tobias Ulmer. Unbreak zfs module build on sparc{,64} by hiding DELAY. ZFS has a conflicting definition of delay() and tries to hide it by defining __HIDE_DELAY.
1.59	07-Jan-2019	jdolecek	move DEV_BSIZE, DEV_BSHIFT out of MD param.h, they are same on all ports also move BLKDEV_IOSIZE, MAXPHYS, but allow override since some ports have different value (powerpc uses NBPG for BLKDEV_IOSIZE, sun2/sun3 have lower MAXPHYS)

1.55	08-Oct-2014	macallan	branches: 1.55.2; Ths has been sitting in my tree for years... Allow the Xserver to map PCI IO space. Not needed for Sun-branded graphics cards but Xorg can actually cold boot a few others, which will need it. ( if only to access standard VGA registers )
1.54	10-Jul-2014	jdc	Increase maximum MSGBUFSIZE to 248k. While here, remove 2 sparc(32)-only entries (from mrg@).
1.53	21-Feb-2014	palle	branches: 1.53.2; sun4v: Rename TLB_ defines to SUN4U_TLB_ so entries created using TSB_DATA() are properly setup for sun4u and sun4v. Relocate the cputyp variable from autoconf.c to locore.s and make it const in param.h so optimized code can be generated. Parts from OpenBSD. Optimization suggested by nakayama@. OK martin@, mrg@, nakayama@
1.52	16-Dec-2013	palle	Updates to pmap_bootstrap() for sun4v - parts from OpenBSD - OK martin@
1.51	03-Jan-2013	martin	branches: 1.51.2; Rearange VA layout for 64 bit kernels, as suggested by Lars Heidieker: move the dynamic kernel memory past 4GB (basically unlimiting it) and use the now freed address range past kernel data upto 2GB for modules.
1.50	10-Mar-2012	nakayama	branches: 1.50.2; Fix previous, which causes an integer overflow error in uvm_km.c on 32-bit kernels.
1.49	09-Mar-2012	jdc	Restrict NKMEMPAGES to 2.5GB, otherwise we will run out of space in the kernel_map on machines with 8GB (or more) main memory. XXX: Moving KERNBASE/KERNEND is a better long term solution, but this allows those machines to boot now.
1.48	04-Feb-2012	para	branches: 1.48.2; improve sizing of kmem_arena now that more allocations are made from it don't enforce limits if not required ok: riz@
1.47	24-Jan-2012	christos	Use and define ALIGN() ALIGN_POINTER() and STACK_ALIGN() consistently, and avoid definining them in 10 different places if not needed.
1.46	20-Jan-2012	joerg	Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions again. This was changed in sys/socket.h r1.51 to work around fallout from the IPv6 aux data migration. It broke the historic ABI on some platforms. This commit restores compatibility for netbsd32 code on such platforms and provides a template for future changes to the CMSG_* alignment. Revert PCC/Clang workarounds in postfix and tmux.
1.45	12-May-2011	mrg	branches: 1.45.4; 1.45.8; first steps towards fujitsu SPARC64 support: - add CPU_SUN4US and CPU_SUN4V defines - re-introduce "cputyp" and use it for sun4u/sun4us/sun4v
1.44	08-Feb-2010	joerg	branches: 1.44.2; 1.44.4; Remove separate mb_map. The nmbclusters is computed at boot time based on the amount of physical memory and limited by NMBCLUSTERS if present. Architectures without direct mapping also limit it based on the kmem_map size, which is used as backing store. On i386 and ARM, the maximum KVA used for mbuf clusters is limited to 64MB by default. The old default limits and limits based on GATEWAY have been removed. key_registered_sb_max is hard-wired to a value derived from 2048 clusters.
1.43	26-Aug-2008	rjs	branches: 1.43.14; Set MACHINE to sparc for 32bit kernels. Approved by martin.
1.42	17-Oct-2007	garbled	branches: 1.42.16; 1.42.20; 1.42.22; 1.42.26; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.41	06-Sep-2007	martin	Remove the (now unused) second 64k page mapped per CPU. From matthew green, with small changes by me. All bugs are mine.
1.40	25-Aug-2007	martin	branches: 1.40.2; Remove INITSTACK completely - at the time we used to switch to it, we already have access to all of lwp0 and it's uarea - so we can switch to the correct lwp0 stack easily before calling main.
1.39	17-May-2007	yamt	branches: 1.39.4; 1.39.8; merge yamt-idlelwp branch. asked by core@. some ports still needs work. from doc/BRANCHES: idle lwp, and some changes depending on it. 1. separate context switching and thread scheduling. (cf. gmcgarry_ctxsw) 2. implement idle lwp. 3. clean up related MD/MI interfaces. 4. make scheduler(s) modular.
1.38	24-Jan-2007	hubertf	branches: 1.38.2; 1.38.6; 1.38.8; 1.38.14; Remove duplicate #includes, patch contributed in private mail by Slava Semushin <slava.semushin@gmail.com>. To verify that no nasty side effects of duplicate includes (or their removal) have an effect here, I've compiled an i386/ALL kernel with and without the patch, and the only difference in the resulting .o files was in shifted line numbers in some assert() calls. The comparison of the .o files was based on the output of "objdump -D". Thanks to martin@ for the input on testing.
1.37	17-Oct-2006	mrg	allocate 128KB (as opposed to 64KB) per-cpu, and place the interrupt stack, cpu_info structure, panicstack, idle uarea and normal kernel stack in here. the idle uarea and kernel stack are in the 2nd 64KB page. the interrupt stack and cpu_info structure are as the same place in the 1st 64KB page, and the panicstack grows down from the top of this page. update comments in param.h to suit (XXX: a lot of these constants should move to a header file that will not pollute the name space so much.) map these pages identically between cpu_initialise() and cpu_mp_startup(), and deal with the two 64KB pages in pmap_extract(). keep an unmapped 64KB page between them. don't initialise the unused "ci_eintstack" member of the cpu_info structure use constants to initialise many addresses in the cpu_info structure, consolidating these assignments from cpu0 and cpu>0 delete u0/estack0/panicstack from locore.s clean up some wrong comments in locore.s fix a 32bit-only bug in cpu_mp_startup(). delete 'u0' entirely. this fixes recent random lossage seen on port-sparc64: processes stuck in RUN state, data faults, and hangs.
1.36	28-Aug-2006	yamt	branches: 1.36.2; 1.36.4; - remove unused bdbtofsb. - move the following macros from MD headers to sys/param.h. ctod dtoc ctob btoc dbtob btodb

1.30	18-Apr-2002	eeh	branches: 1.30.2; Calculate NBPG from PGSHFT.
1.29	08-Apr-2002	eeh	Add a nice 64-bit mstohz() and clean out some cruft.
1.28	26-Feb-2002	simonb	Purge CLSIZE, CLSIZELOG2 and MCLOFSET. Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS are defined. Remove old VM constants from cesfic port. Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).
1.27	09-Feb-2002	eeh	Increase NMBCLUSTERS.
1.26	04-Dec-2001	darrenr	defopt "options SUN4*", put #define for each of SUN4, SUN4C, SUN4M and SUN4U into opt_arch_sparc.h and include this wherever they are used.
1.25	30-May-2001	mrg	branches: 1.25.2; 1.25.8; use _KERNEL_OPT
1.24	11-Feb-2001	eeh	branches: 1.24.2; Increase NKMEMPAGES to a more useful value.
1.23	28-Sep-2000	eeh	Separate user and kernel address spaces and move the kernel down to 0x0000000001000000 -- 0x00000000f0000000, below the PROM where the PROM thinks we should be.
1.22	30-Jun-2000	itojun	raise MSIZE from 128 to 256. - for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small already (less than 80) and there are chances for unwanted packet loss due to m_pullup restriction. - for other cases, the change should avoid allocating clusters in most cases (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of extension header) portmasters: if your arch chokes with the change (high memory usage or whatever), please backout the change for your arch.
1.21	24-Jun-2000	eeh	Get rid of vaddrs.h.
1.20	19-Jun-2000	eeh	branches: 1.20.2; Have separate data and text segments, make text read-only.

1.16	11-Feb-2000	thorpej	Update for the NKMEMPAGES changes.
1.15	04-Dec-1999	ragge	CL* discarding.
1.14	27-Nov-1999	mrg	minor cosmetic merges; long way to go here.
1.13	21-Nov-1999	eeh	Move KERNBASE down from 0xf8000000 to 0xf1000000, just beyond the PROM.
1.12	20-Nov-1999	eeh	Limit buffers to 1/4 of the kernel address space.
1.11	07-Jun-1999	eeh	branches: 1.11.2; 1.11.8; Another general cleanup: Remove the entire idea of fasttrap interrupts since V9 traps are really cheap, the CPUs are really fast, and the completely different trap frames would make these handlers really difficult to implement. pmap_changeprot() was only used by the clock and one other place; deprecate it. probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we can probe IO locations by physical addresses. Some pmap cleanup. Some more copyright cleanup.
1.10	05-Jun-1999	eeh	Make pbrobeget() and probeset() work for 64-bit values as well. To do this the arguments are changed so the address is first and the ASI second so we can have the address in %o0:%o1 and not worry about unused registers. Also a bit of copyright cleanup.
1.9	31-Jan-1999	mrg	branches: 1.9.4; retire _LP64; use compiler provided __arch64__, but still defined _LP64 where we used to anyway.
1.8	06-Oct-1998	eeh	It seems taht 64-bit kernels need bigger stacks.
1.7	09-Sep-1998	thorpej	If _LP64, set MID_MACHINE to MID_SPARC64, else MID_SPARC. This allows us to uniquely identify ILP32 vs. LP64 core files, and prevents an LP64 kernel from incorrectly choosing emul_netbsd when it should choose emul_sparc32.
1.6	09-Sep-1998	eeh	Change to MACHINE_ARCH=sparc64 for LP64 machines.
1.5	06-Sep-1998	eeh	32-bit fixup.
1.4	02-Sep-1998	eeh	Periodic update: now starts probing devices.

1.11.8.1	21-Dec-1999	wrstuden	Initial commit of recent changes to make DEV_BSIZE go away. Runs on i386, needs work on other arch's. Main kernel routines should be fine, but a number of the stand programs need help. cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512 byte block devices. vnd, raidframe, and lfs need work. Non 2**n block support is automatic for LKM's and conditional for kernels on "options NON_PO2_BLOCKS".

1.11.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.17.2.1	22-Jun-2000	minoura	Sync w/ netbsd-1-5-base.

1.31	23-Jun-2024	riastradh	pci: Pass cookie through pci_find_device, pci_enumerate_bus, take 2. New functions pci_find_device1 and pci_enumerate_bus1 have the cookie argument. Existing symbols pci_find_device and pci_enumerate_bus are now wrappers for the cookieless version. This will allow pci_find_device callers to pass a cookie through to the match function so they can keep state or pass in extra parameters like b/d/f numbers, which will allow us to nix some horrible kludges in the Linux PCI API emulation for drm (and, perhaps, Intel wifi). This change drops the symbol pci_probe_device, in favour of a new pci_probe_device1 with the cookie argument. But I don't think that requires a revbump because it's only called by MD pci_enumerate_bus1 implementations, which don't live in modules anyway. Take 2: Make sure to handle NULL match function.
1.30	20-May-2024	riastradh	Revert "pci: Pass cookie through pci_find_device, pci_enumerate_bus." Evidently something is wrong with this, to be diagnosed and redone once the builds and tests are in better shape.

1.25	04-Apr-2011	dyoung	branches: 1.25.4; 1.25.14; Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9), pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match predicate passed to pciide_compat_intr_establish() should ever modify their pci_attach_args argument, so make their pci_attach_args arguments const and deal with the fallout throughout the kernel. For the most part, these changes add a 'const' where there was no 'const' before, however, some drivers and MD code used to modify pci_attach_args. Now those drivers either copy their pci_attach_args and modify the copy, or refrain from modifying pci_attach_args: Xen: according to Manuel Bouyer, writing to pci_attach_args in pci_intr_map() was a leftover from Xen 2. Probably a bug. I stopped writing it. I have not tested this change. siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args. Probably a bug. I use a temporary variable. I have not tested this change. slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args. Probably a bug. Use a local pci_attach_args. I have not tested this change. viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the caller's pci_attach_args. Probably a bug. Make a local copy of the caller's pci_attach_args and modify the copy. I have not tested this change. While I'm here, make pci_mapreg_submap() static.

1.13	16-May-2002	thorpej	branches: 1.13.2; * Add "pcitag_t pba_bridgetag" to pci_attach_args. This is set to NULL for root PCI busses. For busses behind a bridge, it points to a persistent copy of the bridge's pcitag_t. This can be very useful for machine-dependent PCI bus enumeration code. Implement a machine-dependent pci_enumerate_bus() for sparc64 which uses OFW device nodes to enumerate the bus. When a PCI bus that is behind a bridge is attached, pci_attach_hook() allocates a new PCI chipset tag for the new bus and sets it's "curnode" to the OFW node of the bridge. This is used as a starting point when enumerating that bus. Root busses get the OFW node of the host bridge (psycho). * Garbage-collect "ofpci" and "ofppb" from the sparc64 port.
1.12	15-May-2002	thorpej	Let machine-dependent code specify how to enumerate the bus. Currently, everyone uses pci_enumerate_bus_generic().

1.5	28-Dec-2000	sommerfeld	Change pci_intr_map to get interrupt source information from a "struct pci_attach_args *" instead of from four separate parameters which in all cases were extracted from the same "struct pci_attach_args". This both simplifies the driver api, and allows for alternate PCI interrupt mapping schemes, such as one using the tables described in the Intel Multiprocessor Spec which describe interrupt wirings for devices behind pci-pci bridges based on the device's location rather the bridge's location. Tested on alpha and i386; welcome to 1.5Q
1.4	04-Jun-2000	cgd	Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
1.3	01-Jun-2000	cgd	kill __P in these files. (I had to look at them anyway with an eye for adding some protos... and adding them with __P seems wrong, but mixing __P and not __P in the same file seems wrong too, so...)
1.2	24-May-2000	eeh	branches: 1.2.2; Use the PCI function code to distinguish simba bus A from bus B instead of the current hack.
1.1	04-Jun-1999	mrg	branches: 1.1.2; 1.1.4; PCI driver for the UltraSPARC. this only works on the Ultra5/10 machines (`SUNW,sabre') for now, and it doesn't really quite work there yet anyway. the bus space/dma code is cloned from the sbus driver. the IOMMU code also is cloned from the sbus code, but separated out into iommu.c so that we can share it with the sbus driver. hopefully, much of the bus space/dma code can also be re-shared with the sbus driver and the ebus driver but for now these copies will do. support for the real UltraSPARC PCI (`SUNW,psycho') is unwritten, though most of this code is shared with it. we can probe PCI config space and try to configue devices, but interrupts don't work yet...

sys/external/bsd/drm2/dist/drm/drm_gem.c: revision 1.24 sys/arch/xen/xen/xpci_xenbus.c: revision 1.29 drm: Eliminate __HAVE_ATOMIC_AS_MEMBAR conditionals. Discussed on tech-kern: https://mail-index.netbsd.org/tech-kern/2023/02/23/msg028729.html linux asm/barrier.h: Fix !MULTIPROCESSOR build. remove "nouveau" from a comment. noted by jmcneill. drm: KASSERT(A && B) -> KASSERT(A); KASSERT(B) comment a function that has a clear overbounds read but it isn't used. found by GCC 12. nix the NetBSD specific GEM_BUG_ON(). avoids GCC 12 warnings, and matches upstream closer. avoid uninitialised variable usage in drm_gem_cma_create_internal(). in the case nothing has returned 'error', 'nsegs' and the dma info are (potentially) uninitialised, so consider this an error. found by GCC 12. avoid a GCC 12 warning. there's a 1-element long array and a loop conditional that tries to see if indexes for it are not identical. as these indexes will always both be 0, the only valid index, the condition is always false. GCC 12 triggers a strange warning on this code that can never run (see below), so simply assert the array size is 1 and comment the rest. amdgpu_dc_stream.c:470:55: error: array subscript [0, 0] is outside array bounds of 'struct dc_writeback_info[1]' [-Werror=array-bounds] 470 \| stream->writeback_info[j] = stream->writeback_info[i]; convert a KASSERT() into an if () panic() sequence to appease GCC 12. OK riastradh@. drm: Fix conditionals around drmkms_pci and agp. Kernel should build now with all pci drm drivers stripped out but DRM_LEGACY still enabled. (Might not be very useful, but it'll build. Maybe we should also have DRM_LEGACY_PCI so those drivers can be modloaded later.) drmkms: Fix module build. avoid an unlikely array bounds issue picked up by GCC 12. nvkm_pcie_speed() can return -1, which is then used as an array index, so make this default return PCIe 1.0 speeds. drm: enable almost all PCIe functionality linux_pci.c revisions 1.24 and 1.25 implemented most of the remaining missing PCIe backends, but only enabled them for some amdgpu portions. this enables all code marked with "XXX amdgpu pcie", "XXX radeon pcie", and "XXX pcie speed". for most of it, simply removing #ifndefs __NetBSD__ to enable compliation was required, once the new "bus->max_bus_speed" member was added to struct pci_bus. add an "always fails" backend for pci_enable_atomic_ops_to_root() which seems to only be necessary for virtual GPU functionality (and could be implemented if needed.) tested on radeon 5450, 7750, R7 240 [radeon], and RX 550 [amdgpu], and nvidia 750 and 1030 [nouveau]. this still does not quite work on nvidia cards. there are two problems that remain: - the call to set the link speed is skipped because the speed is set to the default value of "-1". nvkm_pcie_set_link() will actually determine the right value for this and for some cards, calling this function if the current speed is -1 helps set the link speed. it may be that on linux other paths we don't have enabled properly would set this (there's one via debugfs, and a jetson specific one, though perhaps setting either AC or DC speed values as boot options (after hooking up these for netbsd) would currently work. - worse, cards newer than kepler - geforce 900, 1000, and newer, are all lacking the backing support to set pcie link speed. the GT 1030 card i have been testing with remains at pcie 1.0. radeon: fix and enable ACPI methods for getting ROM BIOS The hacky way of getting the BIOS mapped only works on x86. ACPI should be preferred if available. Makes BIOS reading though VFCT work on aarch64 with EDK2. (But only if EDK2 has POSTed the GPU.) XXX amdgpu should get the same treatment. drm: put_cpu() should enable preemption, not disable it again drm(4): make pr_debug equivalent to aprint_debug significantly reduces the default spam from amdgpu(4). drm: Set CONFIG_ACPI in linux/acpi.h and make it build. Leave a little ACPI-related functionality disabled for now, like getting EDID out of ACPI -- needs a bit more work to make this work, and I don't have hardware to work on that. Should help with failures of the forms: - unable to locate a BIOS ROM - bios: unable to locate usable image on various machines. radeon_acpi.c: ifdef out unused function on NetBSD. Should fix syzkaller build. drm(4): Fix st_rdev in stat. dminor->index already has the 64*type adjustment, as allocated in drm_minor_alloc. PR kern/58180 linux_sync_file: Fix missing init/fini steps.

Should fix crash on boot with amdgpu now that the ACPI business is enabled. i915: Fix dmabuf mmap object. drm: Fix missing bounds checks in dma buf mmap. drm_gem.c: Fix sense of assertion. This is the opposite of WARN_ON. Noted by rjs@. drm_gem.c: Enable drm_gem_fence_array_add now that we emulate xa. linux_xa: Delete and replace collision in xa_store as intended. Don't free the colliding node that's still in the tree. Noted by rjs@. i915_gem_mman.c: Apply mmap types via pmap flags. This way, userland gets buffers mapped write-combining or uncached as needed. PR xsrc/58307 x86: Teach bus_dmamem_map about BUS_DMA_PREFETCHABLE. PR port-amd64/58308 bus_dma(9): Document BUS_DMA_PREFETCHABLE. Like BUS_DMA_NOCACHE. Doesn't absolve you of the need for bus_dmamap_sync, but if you later pass the vaddr to bus_dmamap_load, the DMA map might notice the mapping is write-combining and use this to make bus_dmamap_sync cheaper. PR kern/58309 nouveau_nvkm_subdev_instmem_gk20a.c: Use BUS_DMA_PREFETCHABLE. Matches Linux's pgprot_writecombine. Unclear where the appropriate bus_dmamap_sync happens, or is supposed to happen -- not using it would be wrong, but asking for a prefetchable mapping may paper over symptoms, at least! ttm: Sync more with Linux. Add the original copyright and attribution since this is now, intentionally, a modified copy of the original and not just roughly the same algorithm. ttm: Respect PGO_ALLPAGES. Not sure this is useful but it reduces XXX's and makes this match udv_fault better so it's easier to understand. ttm: Sync cacheability flag logic with Linux. ttm: Add XXX about readahead fault failures. pci: Pass cookie through pci_find_device, pci_enumerate_bus, take 2. New functions pci_find_device1 and pci_enumerate_bus1 have the cookie argument. Existing symbols pci_find_device and pci_enumerate_bus are now wrappers for the cookieless version. This will allow pci_find_device callers to pass a cookie through to the match function so they can keep state or pass in extra parameters like b/d/f numbers, which will allow us to nix some horrible kludges in the Linux PCI API emulation for drm (and, perhaps, Intel wifi). This change drops the symbol pci_probe_device, in favour of a new pci_probe_device1 with the cookie argument. But I don't think that requires a revbump because it's only called by MD pci_enumerate_bus1 implementations, which don't live in modules anyway. Take 2: Make sure to handle NULL match function. linux_pci: Nix pci enumeration kludges. Now that we can pass a cookie through, this stuff will be a little less fragile. i915: Omit needless i915_gem_object_pin/unpin_pages cycle in fault. vm_fault_cpu and vm_fault_gtt, called by i915_gem_fault, already do the pinning and unpinning internally, so there is no need for i915_gem_fault to do it. No functional change intended, except that the transient pin count will be one lower than before during the fault routine (but it will still be positive). i915: Match Linux fault routine return code actions. Omit needless EINTR interception -- this is now handled by i915_error_to_vmf_fault. Earlier revert was over a false alarm -- bisection shows the new warnings arose from linux_pci.c 1.29 here: https://mail-index.netbsd.org/source-changes/2024/06/23/msg151929.html linux_pci: Fix shifto in pci_get_class. It looks like Linux's pci_get_class also matches the interface part of the PCI class register (but not the revision part), and I hadn't noticed that in the previous shim structured differently. With GCC12 kernel ALL/amd64 triggers "'sor' may be used uninitialized". If "sublinks & 3" is zero GCC is right and sor[1] may be returned unitialized. Fix by initializing "sor" to zero to return -1 instead of uninitialized value. Ok: Taylor R Campbell <riastradh@> amdgpu: Map BAR 2, not BAR 5, on pre-bonaire chips.

1.54	12-Jun-2011	rmind	Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

1.29	24-Aug-2003	chs	add support for non-executable mappings (where the hardware allows this) and make the stack and heap non-executable by default. the changes fall into two basic catagories: - pmap and trap-handler changes. these are all MD: = alpha: we already track per-page execute permission with the (software) PG_EXEC bit, so just have the trap handler pay attention to it. = i386: use a new GDT segment for %cs for processes that have no executable mappings above a certain threshold (currently the bottom of the stack). track per-page execute permission with the last unused PTE bit. = powerpc/ibm4xx: just use the hardware exec bit. = powerpc/oea: we already track per-page exec bits, but the hardware only implements non-exec mappings at the segment level. so track the number of executable mappings in each segment and turn on the no-exec segment bit iff the count is 0. adjust the trap handler to deal. = sparc (sun4m): fix our use of the hardware protection bits. fix the trap handler to recognize text faults. = sparc64: split the existing unified TSB into data and instruction TSBs, and only load TTEs into the appropriate TSB(s) for the permissions. fix the trap handler to check for execute permission. = not yet implemented: amd64, hppa, sh5 - changes in all the emulations that put a signal trampoline on the stack. instead, we now put the trampoline into a uvm_aobj and map that into the process separately. originally from openbsd, adapted for netbsd by me.
1.28	10-Aug-2003	chs	remove some leftover cruft.
1.27	14-Apr-2003	petrov	branches: 1.27.2; clean-up unused definition.
1.26	02-Apr-2003	thorpej	Use PAGE_SIZE rather than NBPG.
1.25	31-Jan-2003	martin	Make the pmap count resident/wired mappings on the fly instead of walking the page tables whenever this information is needed. Add an option PMAP_COUNT_DEBUG to assert the new counts and the page table walk agree. The old solution had very bad performance impact, for example by the high CPU load when running top(1). Thanks to Simon Burge for pointing at the cause of the problem and to Valeriy E. Ushakov for optimizing my simple minded assembler code.
1.24	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.23	22-Sep-2002	chs	many improvements: - use struct vm_page_md for attaching pv entries to struct vm_page - change pseg_set()'s return value to indicate whether the spare page was used as an L2 or L3 PTP. - use a pool for pv entries instead of malloc(). - put PTPs on a list attached to the pmap so we can free them more efficiently (by just walking the list) in pmap_destroy(). - use the new pmap_remove_all() interface to avoid flushing the cache and TLB for each pmap_remove() that's done as we are tearing down an address space. - in pmap_enter(), handle replacing an existing mapping more efficiently than just calling pmap_remove() on it. also, skip flushing the TSB and TLB if there was no previous mapping, since there can't be anything we need to flush. also, preload the TSB if we're pre-setting the mod/ref bits. - allocate hardware contexts like the MIPS pmap: allocate them all sequentially without reuse, then once we run out just invalidate all user TLB entries and flush the entire L1 dcache. - fix pmap_extract() for the case where the va is not page-aligned and nothing is mapped there. - fix calculation of TSB size. it was comparing physmem (which is in units of pages) to constants that only make sense if they are in units of bytes. - avoid sleeping in pmap_enter(), instead let the caller do it. - use pmap_kenter_pa() instead of pmap_enter() where appropriate. - remove code to handle impossible cases in various functions. - tweak asm code to pipeline a little better. - remove many unnecessary spls and membars. - lots of code cleanup. - no doubt other stuff that I've forgotten. the result of all this is that a fork+exit microbenchmark is 34% faster and a fork+exec+exit microbenchmark is 28% faster.
1.22	16-Apr-2002	eeh	We want pages modulo 16K not modulo 32K.
1.21	24-Sep-2001	eeh	branches: 1.21.4; Change bus_space_mmap() signature to the official one.
1.20	23-Sep-2001	chs	implement pmap_wired_count().
1.19	10-Sep-2001	chris	Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.
1.18	31-Aug-2001	martin	branches: 1.18.2; Move struct segmap declaration inside #ifndef _LOCORE to make locore.s compilable again.
1.17	30-Aug-2001	mrg	add some sun4/sun4c/sun4m compat code so we can build 32 bit kvm. (these files are not even vaguely syncable.)
1.16	22-Apr-2001	thorpej	branches: 1.16.2; Undo a misguided previous change to the pmap_update() API.
1.15	22-Apr-2001	thorpej	Give pmap_update() an argument (a pmap_t) so that it knows which pmap it should be updating.
1.14	21-Apr-2001	thorpej	#define away pmap_update() in <machine/pmap.h> so that no function call overhead is incurred as we start sprinkling pmap_update() calls throughout the source tree (no pmaps currently defer operations, but we are adding the infrastructure to allow them to do so).
1.13	29-Oct-2000	eeh	branches: 1.13.2; Add pmap_growkernel().
1.12	11-Sep-2000	eeh	Add locking to pmap operations and support multiple physical memory segments.
1.11	30-Dec-1999	eeh	branches: 1.11.4; Implement PMAP_PREFER().
1.10	07-Jun-1999	eeh	branches: 1.10.2; Another general cleanup: Remove the entire idea of fasttrap interrupts since V9 traps are really cheap, the CPUs are really fast, and the completely different trap frames would make these handlers really difficult to implement. pmap_changeprot() was only used by the clock and one other place; deprecate it. probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we can probe IO locations by physical addresses. Some pmap cleanup. Some more copyright cleanup.
1.9	28-Mar-1999	eeh	branches: 1.9.4; Fix fault handling code to correctly report access_type and fault_type and get rid of pmap_enter_phys().
1.8	22-Sep-1998	eeh	More fixup in the signal area. 64-bit syscall cleanup. Add emulation for some new FPU insns: conversion to 64-bit long int and conditional moves.
1.7	13-Sep-1998	eeh	Fixup signal changes (hopefully). However SUN_COMPAT is likely broken by this and I don't know how to fix it. We can now exec a 64-bit init through a really ugly hack (don't ask.)
1.6	09-Sep-1998	thorpej	Adjust for the new "reaper" kernel thread: do not free the vmspace and u-area in machine-dependent code. Instead, call exit2() to schedule the reaper to free them for us, once it is safe to do so (i.e. we are no longer running on the dead proc's vmspace and stack).
1.5	30-Aug-1998	eeh	Some more 64-bit cleanup. Now everything compiles.
1.4	27-Aug-1998	eeh	Add 64-bit pmap support: Moved from a two level 512/1024 entry setup mapping 32 (9/10/13) bits respectively to a three level 1024/1024/1024 entry setup mapping 43 (10/10/10/13) bits. In 32-bit mode we waste about 1/12 pages mapping the high 11 bits. We also only manage 43 of the possible 44 bits of virtual address space, wasting half of it. Oh well, maybe we'll do better next revision.
1.3	13-Aug-1998	eeh	Merge paddr_t changes into the main branch.

1.2	12-Jul-2018	maxv	Remove the kernel PMC code. Sent yesterday on tech-kern@. This change: * Removes "options PERFCTRS", the associated includes, and the associated ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is good. * Removes the PMC code of ARM XSCALE. * Removes all the pmc.h files. They were all empty, except for ARM XSCALE. * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The definitions are put in sysarch.h. * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control and sys_pmc_get_info syscalls. They are marked as OBSOL in kern, netbsd32 and rump. * Removes the pmc_evid_t and pmc_ctr_t types. * Removes all the associated man pages. The sets are marked as obsolete.
1.1	07-Aug-2002	briggs	branches: 1.1.2; 1.1.4; 1.1.6; 1.1.202; 1.1.204; Implement pmc(9) -- An interface to hardware performance monitoring counters. These counters do not exist on all CPUs, but where they do exist, can be used for counting events such as dcache misses that would otherwise be difficult or impossible to instrument by code inspection or hardware simulation. pmc(9) is meant to be a general interface. Initially, the Intel XScale counters are the only ones supported.

This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.64	02-Sep-2023	jdc	sparc64: fix interrupt level mapping for disk and and parallel devices on SBUS-based machines Change the mapping from PIL_SCSI to PIL_BIO, so that they interrupt above the highest soft interrupt (softserial) Remove unused PIL_SCSI, PIL_FDSOFT, PIL_AUSOFT and fix the printf in fdc.c Add "socal" and "SUNW,bpp" to the interrupt map.
1.63	11-Jul-2023	martin	Move the definition of ipl_cookie_t out of the kernel-only sections, some _KMEMUSER applications need it.
1.62	02-Nov-2021	ryo	branches: 1.62.4; In order to prevent _mcount() from being recursively called when built with COPTS=-O0, sprinkle `__always_inline' to make _mcount() be generated as a single function.
1.61	13-Nov-2019	nakayama	Revert workarounds for clang. In-tree clang can now handle the "r" asm constraint for 64-bit values properly.
1.60	06-Apr-2019	nakayama	The real cause for removing asm inline code on clang is that the "r" constraint cannot handle 64-bit and is treated as 32-bit. So code that refers to the upper 32-bit (manuf or impl) of the %ver register is removed by optimization. Use 32-bit kernel code as a workaround when referring to the %ver register.
1.59	05-Apr-2019	nakayama	Put "memory" to asm inline reading privilege registers for clang to prevent it from being removed by excessive optimization.

1.56	25-Dec-2014	nakayama	Put "memory" to asm inline for reading privilege registers on sun4v to avoid issuing rdpr %ver before checking cputyp as a result of code moving by compiler optimization.
1.55	05-Dec-2014	nakayama	Use GETVER_CPU_* macros.
1.54	05-Dec-2014	nakayama	Make getver() into a constant function since Version Register (%ver) is read only and its value is constant. This change reduces multipule %ver reads to one in the functions which uses a number of CPU_IS_* macros.
1.53	18-Aug-2013	martin	branches: 1.53.4; 1.53.6; Remove ancient spl* variants no longer used
1.52	09-Nov-2012	nakayama	branches: 1.52.2; Make setstick() and getstick() to inline functions.

1.48	25-May-2011	mrg	define MANUF_FUJITSU (and fix CPU_IS_SPARC64_V_UP()) and MANUF_SUN. use CPU_IS_SPARC64_V_UP() to choose some US-III versions of some cache functions.
1.47	12-May-2011	mrg	first steps towards fujitsu SPARC64 support: - add IMPL_* defines for fujitsu SPARC64 processors (mostly from openbsd) - rename CPU_IS_JALAPENO() as CPU_IS_USIIIi() - add GETVER_CPU_MANUF() - add CPU_IS_SPITFIRE() and CPU_IS_SPARC64_V_UP()
1.46	01-Feb-2010	mrg	branches: 1.46.4; 1.46.6; add some macros to check cpu type: GETVER_CPU_IMPL() CPU_IS_JALAPENO() CPU_IS_USIII_UP() and use them in a couple places to choose the right method/index
1.45	15-Jan-2010	nakayama	Add processor implementation codes, from OpenBSD.
1.44	15-Jan-2010	nakayama	Add function names defined by macro in comment for reference.
1.43	04-Dec-2009	nakayama	Bring together similar definitions of inline functions manipulating privileged registers using macro. no functional change.
1.42	25-Nov-2009	rmind	Remove IPL_LPT and IPL_IPI aliases, use the actual IPLs. Fix some broken comments.
1.41	16-May-2009	nakayama	- move definition of tick() from ctlreg.h to psl.h and rename to gettick() for consistency with other functions for reading/writing ASRs. - move definition of tl() from trap.c to psl.h as same as above. - define settick() in psl.h and use it in clock.c. - cosmetic chages in psl.h.
1.40	02-Mar-2008	nakayama	branches: 1.40.4; Correct TSTATE_KERN and TSTATE_USER macros.
1.39	25-Feb-2008	nakayama	Fix macro to convert CCR field between PSR and TSTATE. CCR filed in PSR starts from bit 20, not from bit 19.
1.38	11-Dec-2007	martin	branches: 1.38.4; 1.38.8; Make sure the compiler does not reorder stores accross spl...() calls [or, for completeness, calls changing the processor state]. The mutex code has small race windows otherwise.
1.37	03-Dec-2007	ad	branches: 1.37.2; 1.37.4; 1.37.6; Interrupt handling changes, in discussion since February: - Reduce available SPL levels for hardware devices to none, vm, sched, high. - Acquire kernel_lock only for interrupts at IPL_VM. - Implement threaded soft interrupts.
1.36	16-Feb-2007	ad	branches: 1.36.6; 1.36.22; 1.36.24; 1.36.30; Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts via a soft interrupt. In the near future, softclock will be run from process context.
1.35	26-Dec-2006	ad	Define ipl_t as uint8_t so that it can be packed into a word with a lock byte. Ok yamt@.
1.34	21-Dec-2006	yamt	merge yamt-splraiseipl branch. - finish implementing splraiseipl (and makeiplcookie). http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html - complete workqueue(9) and fix its ipl problem, which is reported to cause audio skipping. - fix netbt (at least compilation problems) for some ports. - fix PR/33218.
1.33	04-May-2006	yamt	branches: 1.33.8; 1.33.10; pull splraiseipl() for sparc64 from newlock branch. reviewed by Martin Husemann.

1.31	16-Feb-2006	perry	Change "inline" back to "__inline" in .h files -- C99 is still too new, and some apps compile things in C89 mode. C89 keywords stay. As per core@.
1.30	24-Dec-2005	perry	branches: 1.30.2; 1.30.4; 1.30.6; Remove leading __ from __(const\|inline\|signed\|volatile) -- it is obsolete.

1.20	13-Apr-2001	thorpej	branches: 1.20.2; 1.20.8; 1.20.12; 1.20.18; Remove the use of splimp() from the NetBSD kernel. splnet() and only splnet() is allowed for the protection of data structures used by network devices.
1.19	02-Mar-2001	mrg	branches: 1.19.2; clean up slightly.
1.18	14-Jan-2001	thorpej	Make sure everybody has an splvm() and equate it with splimp() (splimp() is the historical name for this interrupt level, and the historical name is going to go away in the near future).
1.17	29-Dec-2000	eeh	Lower PIL_SCHED below the zs interrupt so we don't get silo overflows.
1.16	23-Aug-2000	eeh	Update the scheduler to the new locking scheme.
1.15	22-Aug-2000	thorpej	Add spllock(). See spl(9) for details.
1.14	21-Aug-2000	thorpej	Make sure we provide splsched() as described in spl(9).
1.13	23-Jul-2000	eeh	Give 64-bit processes access to a full 64-bit address space (90% of which they can't use anyway, but that's another issue.)
1.12	09-Jul-2000	eeh	Use TSO memory model for 32-bit userland.
1.11	05-Aug-1999	thorpej	branches: 1.11.2; 1.11.12; Fix the raise/lower semantics of splsoftclock()/spllowersoftclock().
1.10	05-Aug-1999	thorpej	Change the semantics of splsoftclock() to be like other spl() functions, that is priority is rasied. Add a new spllowersoftclock() to provide the atomic drop-to-softclock semantics that the old splsoftclock() provided, and update calls accordingly. This fixes a problem with using the "rnd" pseudo-device from within interrupt context to extract random data (e.g. from within the softnet interrupt) where doing so would incorrectly unblock interrupts (causing all sorts of lossage). XXX 4 platforms do not have priority-raising capability: newsmips, sparc, XXX sparc64, and VAX. This platforms still have this bug until their XXX spl() functions are fixed.
1.9	18-Jul-1999	eeh	Lower spl for softints.
1.8	05-Jun-1999	eeh	Fix things up so they compile again.
1.7	26-Mar-1999	eeh	branches: 1.7.4; COMPAT_SPARC32 -> COMPAT_NETBSD32
1.6	31-Jan-1999	mrg	retire _LP64; use compiler provided __arch64__, but still defined _LP64 where we used to anyway.
1.5	05-Sep-1998	eeh	It slices. It dices. It does everything except exec a sparc32_compat init.
1.4	30-Aug-1998	eeh	Some more 64-bit cleanup. Now everything compiles.
1.3	28-Jul-1998	eeh	That last change to reduce warnings wasn't quite right.
1.2	27-Jul-1998	mrg	don't provide a static splx prototype if SPLDEBUG. avoids warnings...
1.1	20-Jun-1998	eeh	branches: 1.1.1; Initial revision

Shows who's waiting for which locks and what the owner is up to. Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>. And thus out of <sys/param.h>, which is exceedingly overused and fragile and delenda est. Should fix (some) issues with the recent inclusion of machine/lock.h in various machine/mutex.h files. arm/mutex.h: Need machine/intr.h, machine/lock.h. For ipl_cookie_t and __cpu_simple_lock_t. evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL. Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which should really be fixed. opencrypto/cryptodev.h: Fix includes. - Move sys/condvar.h under #ifdef _KERNEL. - Add some other necessary includes and forward declarations. - Sort. hp300/intr.h: Fix missing includes. linux/idr.h: Need <sys/mutex.h> for kmutex_t. amiga/intr.h: Don't define spl() functions if !_KERNEL. This is used by crash(8) now, and what's important is ipl_cookie_t. cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8). cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER. Probably not necessary but let's be a little more cautious about this. atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8). arm/cpu.h: Need sys/param.h for COHERENCY_UNIT. Nix machine/param.h -- not meant to be used directly, pulled in by sys/param.h. Move the definition of ipl_cookie_t out of the kernel-only sections, some _KMEMUSER applications need it. ddb: Cast pointer to uintptr_t first before db_expr_t. hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). news68k/intr.h: Fix includes. Put some definitions under _KERNEL. next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). sys/ksem.h: Hack around fstat(8) abuse of _KERNEL. sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). x68k/intr.h: Put functions under _KERNEL so crash(8) can use this. Make ipl_cookie_t visible for _KMEMUSER userland applications. fix editor mishap in previous Explicitly include <sys/mutex.h> for kmutex_t. Replace kmutex_t (which may be undefined here) with struct kmutex , suggested by Taylor. hp300/intr.h: Put most of this under #ifdef _KERNEL. Only ipl_cookie_t really needs to be exposed now, for crash(8). mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8). Make inclusion of sys/intr.h explicit for spl. fix hppa and vax builds. machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in sys/types.h. avoids cpu_data.h vs sched.h include order issues. move the hppa ipl_t typedef with the moved usage of it. machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h. Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which always comes from sys/types.h. And, really, sys/types.h (or at least sys/stdint.h) is needed for uintN_t and uintptr_t. ddb: Cast pointer to uintptr_t, then to db_expr_t. Avoids warnings about conversion between pointer and integer of different size on some architectures. re-fix hppa builds. this file uses __cpu_simple_lock(), not just the underlying type, so it does need machine/lock.h. Break cycle by using `struct kmutex ' instead of `kmutex_t '. sys/sched.h included sys/mutex.h which includes sys/intr.h which includes machine/intr.h which on cats includes arm/footbridge/footbridge_intr.h which includes arm/cpu.h which includes sys/cpu_data.h which includes sys/sched.h But there was never any real need for sys/mutex.h in sys/sched.h, because it only uses pointers to the opaque struct kmutex. Cycle broken by using `struct kmutex *' instead of pulling in sys/mutex.h for the definition of kmutex_t. Side effect: This revealed that sys/cpu_data.h needed sys/intr.h (which was pulled in accidentally by sys/mutex.h via sys/sched.h) for SOFTINT_COUNT. Also revealed some other machine/cpu.h header files were missing includes of sys/mutex.h for kmutex_t. ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t. explicitly include no longer implicitly included sys/mutex.h. arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz. Sidesteps namespace collision with `#define bits ...' in net/zlib.c. complete the previous - there were two calls to find_first_bit() to fix. arm/xscale: Missed a spot with previous find_first_bit commit. evbarm/g42xxeb: Fix off-by-one in previous. The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x), which is equivalent to fls32(x) - 1, not to fls32(x). Note that fls32 is 1-based and returns 0 for x=0.
1.65.2.1	02-Aug-2025	perseant	Sync with HEAD
1.29	07-Jan-2025	andvar	s/bitfeilds/bitfields/ in comment.
1.28	04-Nov-2016	macallan	branches: 1.28.52; add plumbing to support bus_space_mmap() with: - write combining allowed via BUS_SPACE_MAP_PREFETCHABLE - byte order translation via BUS_SPACE_MAP_LITTLE
1.27	03-Apr-2015	palle	branches: 1.27.2; sun4v: There is no L-bit (Locked) in the sun4v tte
1.26	03-Mar-2014	palle	branches: 1.26.6; sun4v: SUN4V_TLB_TSB_LOCK define should have the same LL (instead of UL) as the other defines
1.25	21-Feb-2014	palle	sun4v: Rename TLB_ defines to SUN4U_TLB_ so entries created using TSB_DATA() are properly setup for sun4u and sun4v. Relocate the cputyp variable from autoconf.c to locore.s and make it const in param.h so optimized code can be generated. Parts from OpenBSD. Optimization suggested by nakayama@. OK martin@, mrg@, nakayama@
1.24	16-Dec-2013	palle	Updates to pmap_bootstrap() for sun4v - parts from OpenBSD - OK martin@
1.23	08-Dec-2013	palle	Add support for running ofwboot on sun4v. Please note that the kernel on sun4v will be loaded properly but when the kernel takes over it will crash immediately since the kernel is not sun4v ready yet
1.22	15-Jan-2010	nakayama	branches: 1.22.12; 1.22.22; 1.22.26; Fix typo in previous.
1.21	05-Dec-2009	mrg	- update the TLB_SOFT2_MASK and TLB_DIAG_MASK definitions for USIII. partly from openbsd. - rename TLB_DIAG_MASK to TLB_RESERVED_MASK. from openbsd. - fix the TLB_PA_MASK definition to be correct. our old one was 4 bits too wide. - fix various errors in the #if 0 bitfield version of struct sun4u_tag_fields. tested on U60 and SB2500.
1.20	14-Mar-2008	nakayama	branches: 1.20.4; Complete per-CPU TSBs and MMU contexts changes.
1.19	22-Feb-2008	martin	Get rid of the IPI simple_lock.
1.18	08-Sep-2006	mrg	branches: 1.18.30; 1.18.50; 1.18.54; make this idempotent.
1.17	20-Feb-2006	cdi	branches: 1.17.2; 1.17.14; Use ANSI-style function definitions and declarations.
1.16	11-Feb-2006	cdi	ANSIfication: u_intN_t -> uintN_t, use ANSI function declarations/definitions instead of K&R ones.
1.15	11-Dec-2005	christos	branches: 1.15.2; 1.15.4; 1.15.6; merge ktrace-lwp.
1.14	22-Feb-2005	martin	branches: 1.14.4; Cleanup: the PG_SZ macro was buggy (pointed out by Tim Newsham). It was only used by (the also buggy/not ready for prime time) PMAP_PAGE_SIZE, which in turn only was used in one place. Get rid of all this and hardcode the result at the single place of use.
1.13	14-Mar-2004	chs	branches: 1.13.8; 1.13.10; checkpoint of MP work from dennis and myself. includes cross-processor interrupt framework, a sledgehammer TLB invalidation and misc MP fixes. doesn't work at all yet.
1.12	06-Jan-2003	wiz	branches: 1.12.2; writable, not writeable.
1.11	22-Sep-2002	chs	many improvements: - use struct vm_page_md for attaching pv entries to struct vm_page - change pseg_set()'s return value to indicate whether the spare page was used as an L2 or L3 PTP. - use a pool for pv entries instead of malloc(). - put PTPs on a list attached to the pmap so we can free them more efficiently (by just walking the list) in pmap_destroy(). - use the new pmap_remove_all() interface to avoid flushing the cache and TLB for each pmap_remove() that's done as we are tearing down an address space. - in pmap_enter(), handle replacing an existing mapping more efficiently than just calling pmap_remove() on it. also, skip flushing the TSB and TLB if there was no previous mapping, since there can't be anything we need to flush. also, preload the TSB if we're pre-setting the mod/ref bits. - allocate hardware contexts like the MIPS pmap: allocate them all sequentially without reuse, then once we run out just invalidate all user TLB entries and flush the entire L1 dcache. - fix pmap_extract() for the case where the va is not page-aligned and nothing is mapped there. - fix calculation of TSB size. it was comparing physmem (which is in units of pages) to constants that only make sense if they are in units of bytes. - avoid sleeping in pmap_enter(), instead let the caller do it. - use pmap_kenter_pa() instead of pmap_enter() where appropriate. - remove code to handle impossible cases in various functions. - tweak asm code to pipeline a little better. - remove many unnecessary spls and membars. - lots of code cleanup. - no doubt other stuff that I've forgotten. the result of all this is that a fork+exit microbenchmark is 34% faster and a fork+exec+exit microbenchmark is 28% faster.
1.10	20-Mar-2002	eeh	Add PTE_WIRED bit to keep track of wired pages.
1.9	04-Dec-2001	darrenr	defopt "options SUN4*", put #define for each of SUN4, SUN4C, SUN4M and SUN4U into opt_arch_sparc.h and include this wherever they are used.
1.8	30-Aug-2001	mrg	branches: 1.8.6; add some sun4/sun4c/sun4m compat code so we can build 32 bit kvm. (these files are not even vaguely syncable.)
1.7	31-Jul-2001	eeh	Dump some enums that make lint unhappy and we never really use anyway.
1.6	21-Jun-2001	eeh	branches: 1.6.2; Allow multiple 4MB pages for both kernel text and kernel data. Note: DEBUG checks will not allow accesses to the hole between text and data segments, so you may need to update programs that use libkvm before relocating the start of kernel data.
1.5	05-Jun-1999	eeh	Make pbrobeget() and probeset() work for 64-bit values as well. To do this the arguments are changed so the address is first and the ASI second so we can have the address in %o0:%o1 and not worry about unused registers. Also a bit of copyright cleanup.
1.4	30-May-1999	eeh	Make pmap_enter() handle little-endian mappings properly.
1.3	05-Sep-1998	eeh	branches: 1.3.8; It slices. It dices. It does everything except exec a sparc32_compat init.

1.14	17-Jul-2011	joerg	Retire varargs.h support. Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.13	20-Jul-2002	mrg	use <sparc/foo.h> where appropriate. now these files become very very difficult to get out of sync. add bootinfo.h and promlib.h (using the same method) so that sparc64 headers can build sparc stand (not yet finished.)

1.5	09-Jan-1999	eeh	Don't use `long' instead of `int64_t' since the latter may not be in scope.
1.4	13-Sep-1998	eeh	Fixup signal changes (hopefully). However SUN_COMPAT is likely broken by this and I don't know how to fix it. We can now exec a 64-bit init through a really ugly hack (don't ask.)

1.12	19-Dec-2018	maxv	Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently, but also as discussed several times in the past.
1.11	01-Apr-2015	palle	branches: 1.11.16; 1.11.18; sun4v: Implement handling of cpu_mondo trap - from OpenBSD - tested using the Legion simulator
1.10	08-Jun-2014	palle	branches: 1.10.4; sun4v: make tlb_flush_pte() work on sun4v - parts from OpenBSD - ok martin@
1.9	27-Mar-2011	martin	branches: 1.9.14; 1.9.28; On second thought do not use bit 13 as a flag for syscall numbers, userland typically sets those from a 13bit signed integer immediate field in the instruction, so would need to jump through hoops (ok, small hoops) to avoid sign extension. Use a combination of the existing syscall flags instead.
1.8	23-Mar-2011	martin	Add a syscall variant passing the return address in %g5 (we need %g7 for pthread_self and %g2 is an application register, so we can not use those anymore).
1.7	13-Dec-2010	mrg	branches: 1.7.2; add definitions for T_DATA_MMU_MISS, T_FAST_ECC_ERROR, T_DC_PAR_ERR and T_IC_PAR_ERR, all are >= USIII only.
1.6	19-Sep-2006	mrg	branches: 1.6.78; normalise case in some macro values to be all the same (lower case)
1.5	21-Jan-2003	martin	branches: 1.5.18; 1.5.48; 1.5.50; Rename the DIV0 traps to avoid confusion with the usage on the sparc port: T_IDIV0 is the hardware trap generated on integer division by zero, T_DIV0 is the software trap used to signal the same event. This makes 32 bit kernels able to run sparc code with the v7 multiply/ divide library. Spotted by Valeriy E. Ushakov.
1.4	07-Jun-1999	eeh	Another general cleanup: Remove the entire idea of fasttrap interrupts since V9 traps are really cheap, the CPUs are really fast, and the completely different trap frames would make these handlers really difficult to implement. pmap_changeprot() was only used by the clock and one other place; deprecate it. probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we can probe IO locations by physical addresses. Some pmap cleanup. Some more copyright cleanup.
1.3	05-Jun-1999	eeh	Make pbrobeget() and probeset() work for 64-bit values as well. To do this the arguments are changed so the address is first and the ASI second so we can have the address in %o0:%o1 and not worry about unused registers. Also a bit of copyright cleanup.
1.2	07-Sep-1998	eeh	branches: 1.2.8; Add new 64-bit specific traps and 64-bit Solaris syscall.

1.28	06-Apr-2019	thorpej	branches: 1.28.16; Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe). Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives. Welcome to NetBSD 8.99.37.
1.27	26-Jan-2017	christos	branches: 1.27.14; provide __HAVE_COMPAT_NETBSD32 and fix multiple include protection consistently.

1.22	20-Jul-2002	mrg	branches: 1.22.6; use <sparc/foo.h> where appropriate. now these files become very very difficult to get out of sync. add bootinfo.h and promlib.h (using the same method) so that sparc64 headers can build sparc stand (not yet finished.)
1.21	03-May-2002	thorpej	branches: 1.21.2; Revert revision 1.20.

1.18	04-Dec-2001	darrenr	defopt "options SUN4*", put #define for each of SUN4, SUN4C, SUN4M and SUN4U into opt_arch_sparc.h and include this wherever they are used.
1.17	12-May-2001	kleink	branches: 1.17.2; 1.17.8; Delint my previous change.
1.16	28-Apr-2001	kleink	* Move definitions of exact-width integer types from <machine/types.h> to <sys/types.h> and <sys/stdint.h>. * Add a new C99 <stdint.h> header, which provides integer types of explicit width, related limits and integer constant macros. * Extend <inttypes.h> to provide <stdint.h> definitions and format macros for printf() and scanf(). * Add C99 strtoimax() and strtoumax() functions. * Use the latter within scanf(). * Add C99 %j, %t and %z printf()/scanf() conversions for intmax_t, pointer-type and size_t arguments.
1.15	14-Jan-2001	thorpej	branches: 1.15.2; Rename __GENERIC_SOFT_INTERRUPTS to __HAVE_GENERIC_SOFT_INTERRUPTS, and place the definition in <machine/types.h>. This can now be used as a flag to indicate whether or not <machine/intr.h> can be included to get the generic soft interrupt API.
1.14	03-Jan-2001	takemura	replace 'long long' with int64_t to compile stand alone program with compiler other than GCC.
1.13	04-Dec-2000	mrg	Remove __BROKEN_CONFIG_UNIT_USAGE. (sync with sparc)
1.12	05-Feb-2000	cgd	add __BROKEN_CONFIG_UNIT_USAGE #define, becuase these ports do very wrong things with device configuration data "cf_unit" information.
1.11	01-Feb-2000	danw	#define __HAVE_DEVICE_REGISTER on ports that have it, and check for that, rather than a list of architecture defines, in config_attach
1.10	27-Nov-1999	eeh	Apparently sys/sysctl.h includes vm/vm_map.h which makes use of vaddr_t,

1.8	31-Jan-1999	mrg	branches: 1.8.8; 1.8.14; retire _LP64; use compiler provided __arch64__, but still defined _LP64 where we used to anyway.
1.7	07-Sep-1998	eeh	Make register32_t unsigned so we don't have sign extension problems.
1.6	30-Aug-1998	eeh	Some more 64-bit cleanup. Now everything compiles.
1.5	22-Aug-1998	eeh	Fix typo in previous fix.
1.4	22-Aug-1998	eeh	64-bit-ify this. Depend on _lp64.
1.3	13-Aug-1998	eeh	Merge paddr_t changes into the main branch.
1.2	20-Jun-1998	kleink	branches: 1.2.2; Merge in recent changes: GC the unused `physadr' type, which was not able to hold a complete physical address on 2 architectures anyhow. Also, move the definition of the `label_t' type inside _KERNEL protection, since it is specific to the in-kernel setjmp()/longjmp() implementations.

1.39	03-Sep-2018	riastradh	branches: 1.39.4; 1.39.6; Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

1.36	22-Nov-2015	martin	Reduce the "MAXDSIZ" limit for bottom-up-VA (i.e. old binaries) processes to the old limit of 1 GB. Some old binaries can not deal with more.

Use the same limits as native sparc for netbsd32 emulation - we need to revisit this, but currently automatic test runs in this environment fail big time, so there is no easy way to verify any changes.

Add a new function pointer to struct emul, pointing at a function that will return the default VM map address. The default function is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS macro. This gives emulations control over the default map address, and allows things to be mapped at the right address (in 32bit range) for COMPAT_NETBSD32. * Add code to adjust the data and stack limits when a COMPAT_NETBSD32 or COMPAT_SVR4_32 binary is executed. * Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr instead (emulations might have set it differently) * Since this changes struct emul, bump kernel version to 3.99.2 Tested on amd64, compile-tested on sparc64.

1.21	22-Sep-2002	chs	many improvements: - use struct vm_page_md for attaching pv entries to struct vm_page - change pseg_set()'s return value to indicate whether the spare page was used as an L2 or L3 PTP. - use a pool for pv entries instead of malloc(). - put PTPs on a list attached to the pmap so we can free them more efficiently (by just walking the list) in pmap_destroy(). - use the new pmap_remove_all() interface to avoid flushing the cache and TLB for each pmap_remove() that's done as we are tearing down an address space. - in pmap_enter(), handle replacing an existing mapping more efficiently than just calling pmap_remove() on it. also, skip flushing the TSB and TLB if there was no previous mapping, since there can't be anything we need to flush. also, preload the TSB if we're pre-setting the mod/ref bits. - allocate hardware contexts like the MIPS pmap: allocate them all sequentially without reuse, then once we run out just invalidate all user TLB entries and flush the entire L1 dcache. - fix pmap_extract() for the case where the va is not page-aligned and nothing is mapped there. - fix calculation of TSB size. it was comparing physmem (which is in units of pages) to constants that only make sense if they are in units of bytes. - avoid sleeping in pmap_enter(), instead let the caller do it. - use pmap_kenter_pa() instead of pmap_enter() where appropriate. - remove code to handle impossible cases in various functions. - tweak asm code to pipeline a little better. - remove many unnecessary spls and membars. - lots of code cleanup. - no doubt other stuff that I've forgotten. the result of all this is that a fork+exit microbenchmark is 34% faster and a fork+exec+exit microbenchmark is 28% faster.

These macros are mandatory, but ports may #define them to nothing if they are not needed/used. This deprecates struct pmap_physseg. As a transitional measure, allow a port to #define PMAP_PHYSSEG so that it can continue to use it until its pmap is converted to use VM_MDPAGE_MEMBERS. Use all this stuff to eliminate a lot of extra work in the Alpha pmap module (it's smaller and faster now). Changes to other pmap modules will follow.

1.6	30-Sep-2002	abs	#include "kbd.h" for NKBD and only override cn_isconsole to check cn_hw if set. Fixes compilation without kbd.
1.5	11-Mar-2002	chs	branches: 1.5.6; override cn_trap() with zs_abort() so we can drop to the monitor if there's no DDB. fixes PR 12547.
1.4	08-Nov-2000	eeh	branches: 1.4.4; 1.4.8; Support for MI console magic framework.
1.3	09-Jul-2000	eeh	Upgrate interrupt handling: 1) use interrupt vectors for specific zs chips rather than polling all of them. 2) use softintr_schedule() and schedule it for a particular device rather than poll all devices.
1.2	19-May-2000	eeh	branches: 1.2.4; Fix the sparc64 console. Unlike the other Sun machines, UltraSPARCs can have consoles run on different chips than zs, so we need to support them. So, here we go: Add a new PROM console driver with a major number and everything. This is the default driver if nothing else attaches. It does not use the keyboard driver since the PROM translates keystrokes itself. (Unfortunately it also swallows L1-A). Have the keyboard driver take over the console when it attaches on a serial port. When a serial port detects a keyboard and attaches the keyboard driver, it needs to provide a set of consdev vectors. They keyboard driver will use those to send I/O to the keyboard and mouse.

1.1.1.1.14.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.2.4.1	18-Jul-2000	mrg	pullup the contents of -current arch/sparc64. this gives us significant ultrasparc PCI support (ultra5, ultra10, AXi, and E250 tested so far), plus many other small fixes. netbooting is now supported.
