1.39	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.
1.38	04-Nov-2024	christos	Undo previous lwp.h change.
1.37	03-Nov-2024	christos	Split __lwp_getprivate_fast and __lwp_*tcb from mcontext.h into a separate lwp.h file.
1.36	17-May-2020	ad	branches: 1.36.26; Install sparc/intr.h
1.35	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.
1.34	29-Mar-2018	joerg	branches: 1.34.2; 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.
1.33	23-Jul-2014	alnsn	branches: 1.33.26; Rename sljitarch.h to sljit_machdep.h.
1.32	05-Nov-2012	alnsn	branches: 1.32.10; Add sljitarch.h on sparc.
1.31	17-Jul-2011	joerg	branches: 1.31.2; 1.31.12; 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.
1.30	20-May-2011	nakayama	Add fenv support for sparc. Mostly copied from sparc64 and share with it.
1.29	09-Feb-2007	ad	branches: 1.29.70; 1.29.76; Merge newlock2 to head.
1.28	11-Dec-2005	christos	branches: 1.28.20; merge ktrace-lwp.
1.27	08-May-2004	kleink	branches: 1.27.12; Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.
1.26	11-Apr-2003	jdc	branches: 1.26.2; Install (new) cpuconf.h. From Christopher SEKIYA in PR port-sparc/21093.
1.25	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.24	26-Nov-2002	lukem	Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.
1.22	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.
1.21	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.
1.20	19-Sep-2001	thorpej	branches: 1.20.4; 1.20.8; 1.20.12; Don't do the symlink hack for fbio.h. Just use <dev/sun/fbio.h>.
1.19	15-Apr-2001	kleink	branches: 1.19.2; 1.19.4; Add definitions of C99 integer format conversion macros. XXX Fastest minimum-width integer types haven't been decided upon yet.
1.18	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.
1.17	14-Apr-2001	kleink	Add definitions of C99 integer constant macros. Tidy Makefiles up a little.
1.16	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.
1.15	20-Aug-2000	pk	branches: 1.15.2; fbio.h moded to sys/dev/sun. Retain symlink from /usr/include/machine.
1.14	26-Jun-2000	kleink	Add <machine/int_types.h>, which provides namespace-pure definitions of exact-width integer types.
1.13	29-Apr-2000	thorpej	Oops, install <machine/lock.h> on these systems, too.
1.12	17-Mar-2000	tron	Install "machineendian_machdep.h".
1.11	10-Jan-2000	pk	Cleanup the list of exported headers a bit.
1.10	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.
1.9	20-Dec-1999	jdc	Added tctrl.h
1.8	11-Aug-1999	matt	branches: 1.8.2; 1.8.8; Add <machine/apmvar.h> for sparc so that apmd can be built. Eventually this allow it work on Tadpole SPARCbook 3 laptops (and/or other sparc with power management).
1.7	02-May-1999	christos	Add bootinfo.h
1.6	28-Apr-1999	christos	Support for installboot
1.5	15-Jan-1999	bouyer	branches: 1.5.4; 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.
1.4	22-Aug-1998	mrg	bsd_audioio.h is not used.
1.3	28-Jul-1998	pk	Remove mbppio.h from the list. Also stop installing db_machdep.h, fbvar.h, z8530.h.
1.2	20-Jun-1998	mrg	moved <machine/sun_disklabel.h> to <dev/sun/disklabel.h>
1.1	12-Jun-1998	cgd	Rework the way kernel include files are installed. In the new method, as with user-land programs, include files are installed by each directory in the tree that has includes to install. (This allows more flexibility as to what gets installed, makes 'partial installs' easier, and gives us more options as to which machines' includes get installed at any given time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_ still supported, though at least one bug in the 'symlinks' case is fixed by this change. Include files can't be build before installation, so directories that have includes as targets (e.g. dev/pci) have to move those targets into a different Makefile.

1.2	12-Sep-2020	isaki	Improve am7930 family drivers to share more code. audioamd(4) on sparc, vsaudio(4) on vax, and bba(4) are. - Remove complex and useless callbacks: onopen, onclose, and indirect_{read,write}. This makes audioamd and vsaudio almost the same. - Remove (already disabled) assembly fast interrupt path from audioamd(4). cf. http://mail-index.netbsd.org/source-changes/2009/12/19/msg004585.html - Use trigger_* method rather than start_* method. It's more suitable. vsaudio(4) was tested by naru@, bba(4) was tested by tsutsui@.
1.1	14-Mar-1999	jonathan	Use bus_space tags and handles, embedded in MD hooks AM7930_{READ_WRITE}_REG to handle MD delay and bus padding. Tested on sparc2 by David Brownlee. Should use regmaps, but that breaks sparc pDMA assembly code.
1.25	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.
1.24	17-Jun-2015	martin	branches: 1.24.18; Make clock_t unsigned int everywhere. Ok: matt@, mrg@
1.23	17-Jul-2011	joerg	branches: 1.23.12; 1.23.28; 1.23.30; Retire varargs.h support.

Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.22	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.
1.21	11-Jan-2009	christos	branches: 1.21.4; 1.21.6; merge christos-time_t
1.20	17-Oct-2007	garbled	branches: 1.20.16; 1.20.18; 1.20.22; 1.20.30; 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.
1.19	03-Sep-2007	drochner	clean up some definitions around rune_t which are not needed anymore
1.18	04-Oct-2006	tnozaki	branches: 1.18.8; 1.18.16; 1.18.22; 1.18.26; 1.18.28; 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.
1.17	11-Dec-2005	christos	branches: 1.17.20; 1.17.22; merge ktrace-lwp.

1.15	07-Aug-2003	agc	branches: 1.15.8; 1.15.14; 1.15.18; Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.14	02-Mar-2003	tshiozak	branches: 1.14.2; add some ISO C 1995 I18N functions and types: btowc, wctrans, towctrans, wcscoll, wcsxfrm, wctype_t and wctrans_t.
1.13	03-Jan-2001	takemura	replace 'long long' with int64_t to compile stand alone program with compiler other than GCC.
1.12	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.
1.11	21-Dec-2000	itojun	populate _BSD_MBSTATE_T_. add warning regarding to rune_t.
1.10	27-Jun-2000	kleink	G/c _BSD_INTPTR_T_ and _BSD_UINTPTR_T_.
1.9	05-Jun-1999	pk	branches: 1.9.2; 1.9.10; 64-bit safety to help sharing compilation tools with sparc64.
1.8	27-Apr-1998	kleink	branches: 1.8.10; Provide definitions for intptr_t and uintptr_t, signed resp. unsigned integral types large enough to hold any pointer.
1.7	23-Nov-1997	kleink	Add _BSD_SUSECONDS_T_ and _BSD_USECONDS_T_; do some space vs. tab formatting cleanup
1.6	15-Nov-1996	jtc	Define _BSD_CLOCKID_T_ and _BSD_TIMER_T_
1.5	31-Mar-1996	pk	Various cleanup; mostly trailing spaces/tabs.
1.4	16-Mar-1996	jtc	Add _BSD_WINT_T_ definition so we can handle wint_t type added in NA1.

1.40	31-May-2005	christos	- sprinkle const - remove parameter names from function declarations
1.39	28-Jun-2004	pk	Rename bus_translate_address_generic => bus_space_translate_address_generic() and move prototype to <machine/bus.h>.
1.38	27-Jun-2004	pk	Always use `full bus space'. In order to implement this more efficiently, require that all bus tags have pointers to bus_space_read/write functions, i.e. no run-time hunting for the first "upstream" implementation. Since this changes the way bus tags should be constructed it makes sense to do the same thing for the rest of the bus space methods. So, now bus space tags are generally constructed by copying the parent's bus tag and then overriding the methods that the bus driver needs to handle, instead of starting with an empty bus tag and fiiling in only the fields needed.
1.37	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.

1.21	25-Jan-1998	pk	bus_map() & bus_untmp() are only used for sun4/obio devices.
1.20	24-May-1997	pk	Always use `rr_iospace' to track the MMU page type bits. This obsoletes the `bustype' argument in map[io]dev().
1.19	18-May-1997	pk	Remove bus_tmp().
1.18	08-Apr-1997	pk	Move "range" property description out of generic `romaux'.
1.17	10-Dec-1996	pk	Comply with recent autoconfiguration changes. Diffs graciously supplied by Chris Demetriou.
1.16	10-Apr-1996	pk	Make room for another `value' in struct bootpath. Drop the global `bootdv' in favour of storing the device pointer in the bootpath[] element corresponding to the boot device. This also allows the opportunity to get to "intermediate" devices (e.g. busses) should the need for this ever arise.

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.
1.57	17-Jul-2011	dyoung	Switch sparc and sparc64 to new-style <sys/bus.h>.

1.55	16-Apr-2009	macallan	Add sparc_bus_map_large() to map large bus ranges like framebuffers and apertures outside the IODEV range. ZX for example needs 8MB for the framebuffer alone while the IODEV range provides only 16MB.
1.54	28-Apr-2008	martin	branches: 1.54.8; 1.54.10; 1.54.14; 1.54.18; Remove clause 3 and 4 from TNF licenses

1.52	21-Feb-2007	mrg	add a pair of new bus_dma(9) functions: int _bus_dmatag_subregion(bus_dma_tag_t tag, bus_addr_t min_addr, bus_addr_t max_addr, bus_dma_tag_t *newtag, int flags) void _bus_dmatag_destroy(bus_dma_tag_t tag) that allow a (normally broken/limited) device to restrict the bus address range it can talk to. this is used by bce(4) to limit DMA addresses to 1GB range, the maximum the chip can address. all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several people on tech-kern. XXX: bus_dma(9) needs an update still.

1.45	09-Mar-2005	matt	branches: 1.45.4; Add a dm_maxsegsz public member to bus_dmamap_t. This allows a user of the API to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to bus_dmamap_create when the dmamap is unloaded.

1.42	28-Jun-2004	pk	Rename bus_translate_address_generic => bus_space_translate_address_generic() and move prototype to <machine/bus.h>.
1.41	27-Jun-2004	pk	Always use `full bus space'. In order to implement this more efficiently, require that all bus tags have pointers to bus_space_read/write functions, i.e. no run-time hunting for the first "upstream" implementation. Since this changes the way bus tags should be constructed it makes sense to do the same thing for the rest of the bus space methods. So, now bus space tags are generally constructed by copying the parent's bus tag and then overriding the methods that the bus driver needs to handle, instead of starting with an empty bus tag and fiiling in only the fields needed.
1.40	16-Nov-2003	pk	Use __insn_barrier() in all bus_space read/write operations.
1.39	15-Jun-2003	fvdl	branches: 1.39.2; Handle 64bit DMA addresses on PCI for platforms that can (currently only enabled on amd64). 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.

1.37	03-Jan-2003	martin	Make the _stream_ methods always use the *_real accessors. Define __BUS_SPACE_HAS_STREAM_METHODS.
1.36	03-Jan-2003	mrg	part one of bus_space(9) fixes to enable bus spaces to override the bus_space_{read,write}_[1248]() functions, which will allow 16-bit PCMCIA support to work without additional hacks in MI drivers. this option is not enabled yet.
1.35	10-Dec-2002	pk	Remove the `flags' argument from bus_intr_establish().
1.34	10-Dec-2002	pk	bus_intr_establish() now takes an optional `fast trap' handler argument. BUS_INTR_ESTABLISH_FASTTRAP and BUS_INTR_ESTABLISH_SOFTINTR are no longer used.
1.33	25-Aug-2002	thorpej	Put a bus's ranges in the bus space tag, and make sparc_bus_map() perform the translation and recursion if t->ranges != NULL. Make sbus, cpuunit, and bootbus inherit the parent's map/mmap routines, and delete the now-unused mapping functions. Update all places where bus space tags are statically allocated.

1.22	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.

1.18	09-May-2000	pk	The bus_dma(9) implementation now allocates DVMA addresses in bus_dmamap_load_*() routines only. Note that DMA memory buffers allocated with bus_dmamem_alloc() _must_ be loaded by bus_dmamap_load_raw().
1.17	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)

The __warn_references semicolon change has to be made so that __warn_references can be defined into nothing. (A ; all by itself isn't a great idea.) The __indr_reference change was made for consistency.

This will make it easier for ports that are being bootstraped with ELF and ECOFF based toolchains. This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands its argument, an identifier, to a character string of the identifier name as it is represented in an object file. For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports _C_LABEL(x) will expand to "x".

1.20	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.

(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
1.17	15-Dec-1999	garbled	branches: 1.17.6; Add new spl level for tadpole devices splts102. Device entrypoints for tctrl device (tadpole micro controller) add header for direct-access ioctl to the tadpole microcontroller.
1.16	01-Aug-1999	matt	branches: 1.16.2; 1.16.8; Initial stab at a P9100 console FB driver for the Tadpole 3GX. It supports RASTERCONSOLE only and the colormap support is broken (the hardware doesn't seem to be doing what the tech. docs. say it should be doing). But it is usable as a console (but with blue on white as the only color choice). I figured I'd check it in since it is somewhat usable and someone else might figure what I screwed up in the color map support.
1.15	30-Jul-1999	matt	Add preliminary support for the built-in modem on Tadpole 3GX/S laptops. There is currently something wrong with the interrupt code but it does attach and sense a 16550a. (anyways the built in modem is only a 14.4Kb and you'd really want to use a PCMCIA modem to get faster dialup rates).

1.111	13-Jul-2023	riastradh	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.
1.110	14-Aug-2021	ryo	branches: 1.110.4; 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.

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.
1.102	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().

1.100	16-Jan-2018	mrg	branches: 1.100.2; 1.100.4; 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.
1.99	02-Dec-2017	macallan	- return early in xcall() if the function is sparc_noop() instead of triggering the IPI and then ignoring responses ( or lack thereof ) - write the .tag field last to avoid a race when polling for an incoming IPI - add event counters for IPIs being caught with the mutex not held, and for messages that are already marked as completed With this my SS20 made it through 48 hours of pkgsrc with MAKE_JOBS=3 and a pair of SM81s. Hypersparcs still crash but instead of craziness we get actual error messages, apparently one CPU will occasionally do a watchdog reset, which according to the manual is caused by catching a trap with traps disabled. Now to figure out how that can even happen...

1.82	17-Oct-2007	garbled	branches: 1.82.2; 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.

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.

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.

1.45.4.6	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).

1.45.4.3	08-Dec-2001	thorpej	Add a cpu_proc_fork(), called from uvm_proc_fork(), which takes care of machine-dependent handling a fork() time (this is different from forking the actual context in an LWP world). #define it away on platforms which do not need it. Problem noted by Gregory McGarry.

Hypersparcs still crash but instead of craziness we get actual error messages, apparently one CPU will occasionally do a watchdog reset, which according to the manual is caused by catching a trap with traps disabled. Now to figure out how that can even happen...

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	08-Oct-2016	joerg	Macros expanding to defined() expression is not actually correct ISO C behavior. Since it is not clear whether someone might decide to define the macros to random non-1 values, introduce a level of indirection and count the same of the helper macros.

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.

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.

1.9	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.

It supports RASTERCONSOLE only and the colormap support is broken (the hardware doesn't seem to be doing what the tech. docs. say it should be doing). But it is usable as a console (but with blue on white as the only color choice).

1.7	27-Feb-1996	thorpej	First-cut support for P4 framebuffers. Currently supports P4 variants of bwtwo, cgfour, cgsix, and cgeight. Includes support for attaching the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la SunOS). P4 register descriptions, cgfour driver, and cgeight driver partially derived from OpenBSD. This code may still need polishing.

Fix for issue reported in PR lib/35401 as well as related overflow bugs. deal with hex doubles. Instead of abusing stdio to get a signal-safe version of sprintf, provide one. remove __SAFE add long double and hex double support from freebsd. make this compile. add new prototypes. add the new files to the build. Note I am not bumping libc now, because these are not used yet. Merge the int bit with the high fraction bit. Add constants/macros needed by gdtoa. add constants used by gdtoa since the int bit is merged, do the explicit math. ext_int bit is no more. ext_int bit is no more. - merge change from freebsd - add support for building as vfprintf.c - XXX: we strdup to simplify the freeing logic. This should be fixed for efficiency in the vfprintf case. use vfwprintf.c enable wide doubles. some int -> size_t deal with sparc64 that has 112 bits of mantissa. make extended precision gdtoa friendly. int/size_t changes make this gdtoa friendly. remove dup definition use dtoa() instead of returning empty when we don't have extended precision information. Fix previous, add forgotten pointer dereference in the call to dtoa(). Add a cheesy workaround marked XXX for the situation where the strtod() implementation available in the environment does not handle hex floats. Discussed with and suggested by christos From Christos: gdtoa fixes for m68k. M68k ports should build now, but printing extended precision is a little off. vax does not have <machine/ieee.h> or long double It would be nice if the compiler provided something like __IEEE_MATH__ bring in FreeBSD's vfscanf() to gain multi-byte/collation support. Unfortunately it is too difficult to make vfwscanf and this share the same code like I did with printf, because for string parsing the code is too different.

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.

C99 requires that these definitions promote to (signed/unsigned) integer the same way as the types the definition is for.

C99 requires that these definitions promote to (signed/unsigned) integer the same way as the types the definition is for. And since unsigned char/short fit into an "int" on all our archs and thus promote to signed int, the definitions must not be unsigned. Fixes PR lib/31306 by Neil Booth.

1.14	28-Apr-2003	bjh21	branches: 1.14.2; Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

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.

1.14	15-Feb-2018	kamil	Introduce _UC_MACHINE_FP() as a macro _UC_MACHINE_FP() is a helper macro to extract from mcontext a frame pointer. 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@. Sponsored by <The NetBSD Foundation>
1.13	12-Sep-2012	manu	branches: 1.13.32; 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@
1.12	25-Feb-2011	joerg	branches: 1.12.4; Be nicer to software that insists on -ansi and use __inline.
1.11	24-Feb-2011	joerg	Allow storing and receiving the LWP private pointer via ucontext_t on all platforms except VAX and IA64. Add fast access via register for AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace the stack based pthread_self(). Implement skeleton support for Alpha, HPPA, PowerPC, SPARC and SPARC64, but leave it disabled. Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in machine/types.h and a corresponding __lwp_getprivate_fast in machine/mcontext.h. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.

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@. Sponsored by <The NetBSD Foundation> -- Improve _UC_MACHINE_FP() for SPARC/SPARC64 Introduce a static inline function _uc_machine_fp() that contains improved caluclation of a frame pointer. Algorithm: uptr stk_ptr; # if defined (__arch64__) stk_ptr = (uptr ) (sp + 2047); # else stk_ptr = (uptr ) sp; # endif bp = stk_ptr[15]; Noted by <mrg> -- Make _UC_MACHINE_FP() compile again and fix it so that it does not add the offset twice. -- 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. -- Add new tests in lib/libc/sys/t_ucontext New tests: - ucontext_sp - ucontext_fp - ucontext_pc - ucontext_intrv They test respectively: - _UC_MACHINE_SP - _UC_MACHINE_FP - _UC_MACHINE_PC - _UC_MACHINE_INTRV These tests attempt to access and print the values from ucontext, without interpreting the values. This is a follow up of the _UC_MACHINE_FP() introduction. These tests use PRIxREGISTER, and require to be built with -D_KERNTYPES. Sponsored by <The NetBSD Foundation>

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.

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.

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.

1.74	01-May-2020	isaki	Move machine dependent AUDIO_BLK_MS default value to <machine/param.h>. If the port has __AUDIO_BLK_MS in <machine/param.h>, it will be used. Otherwise the default value (currently 10 msec) defined in audio.c will be used. This mechanism is for very old ports which cannot satisfactorily handle 10 msec block. Currently hppa, m68k, sh3, sparc(!64) and vax are. For port maintainers, if general models in your port cannot satisfactorily handle 10 msec block, please consider to define your suitable longer period (40 msec would be a good first choice). But please don't be eager to make the default value shorter. <machine/param.h> was discussed in source-changes-d. It's better than ifdef storm, or adding 60+ new header files in every arch/*/include/ directories for this. Thanks mrg@, ad@, and everyone. http://mail-index.netbsd.org/source-changes-d/2020/05/01/msg012572.html

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.
1.67	08-Feb-2010	joerg	branches: 1.67.10; 1.67.14; 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.

1.54	17-Jul-2002	thorpej	Instead of using a matrix of configured CPU types, first count how many CPU types are configured into the kernel. Then, use this information to define the CPU predicate macros according to the following rules: 1. If support for a CPU type is not configured into the kernel, then the test is always false. 2. Otherwise, if only one CPU type is configured into the kernel, then the test is always true. 3. Otherwise, we have to reference the cputyp variable. Use a similar strategy for short-cutting the page size related definitions.
1.53	17-Jul-2002	thorpej	Remote CPU_ISSUN4OR4C and CPU_ISSUN4COR4M, and instead express them as (CPU_ISSUN4 \|\| CPU_ISSUN4C) and (CPU_ISSUN4C \|\| CPU_ISSUN4M), respectively. The compiler can still optimize as desired by expressing them this way, and it simplifies adding new tests. While here, just remove CPU_ISSUN4MOR4U; it's not used by anything.

1.50	11-Dec-2001	uwe	microSPARC-IIep is a sun4m but with an integrated PCI controller. In a lot of places (like pmap &c) we want it to be treated as SUN4M. But since various low-level things are done very differently from normal sparcs (and since for now it requires a relocated kernel anyway), the MSIIEP kernels are not supposed to support any other system.

And remove the option from GENERIC. - It's not good idea to set such parameter in individual GENERICs. - 4msec is (probably no problem for most modern real hardware but) too aggressive to be default. - 10msec is too severe for antique machines but it's hard to draw a line. Set AUDIO_BLK_MS 40 msec on other old(slow) architectures not only m68k. Thanks tsutsui@ for comment about architecture choice. And move it from audiodef.h to audio.c as suggested by joerg@. Move machine dependent AUDIO_BLK_MS default value to <machine/param.h>. If the port has __AUDIO_BLK_MS in <machine/param.h>, it will be used. Otherwise the default value (currently 10 msec) defined in audio.c will be used. This mechanism is for very old ports which cannot satisfactorily handle 10 msec block. Currently hppa, m68k, sh3, sparc(!64) and vax are. For port maintainers, if general models in your port cannot satisfactorily handle 10 msec block, please consider to define your suitable longer period (40 msec would be a good first choice). But please don't be eager to make the default value shorter. <machine/param.h> was discussed in source-changes-d. It's better than ifdef storm, or adding 60+ new header files in every arch/*/include/ directories for this. Thanks mrg@, ad@, and everyone. http://mail-index.netbsd.org/source-changes-d/2020/05/01/msg012572.html

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.

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.

Maybe one day we can look at this again. Fixes PR kern/21517.
1.67	08-May-2003	thorpej	Simplify the way the bounds of the managed kernel virtual address space is advertised to UVM by making virtual_avail and virtual_end first-class exported variables by UVM. Machine-dependent code is responsible for initializing them before main() is called. Anything that steals KVA must adjust these variables accordingly. This reduces the number of instances of this info from 3 to 1, and simplifies the pmap(9) interface by removing the pmap_virtual_space() function call, and removing two arguments from pmap_steal_memory(). This also eliminates some kludges such as having to burn kernel_map entries on space used by the kernel and stolen KVA. This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code, this giving MD code greater flexibility over the bounds of the managed kernel virtual address space if a given port's specific platforms can vary in this regard (this is especially true of the evb* ports).
1.66	02-Mar-2003	pk	pmap_changeprot() is not a UVM <-> PMAP interface function; make it internal. Provide pmap_kprotect() for MD code to change protection on a range of kernel addresses (cuurent users: intr.c and mkclock.c).

1.54	22-Apr-2001	thorpej	Remove pmap_kenter_pgs(). It was never really adopted by anything, and the interface itself wasn't as flexible as callers would have probably liked.
1.53	22-Apr-2001	thorpej	Undo a misguided previous change to the pmap_update() API.
1.52	22-Apr-2001	thorpej	Give pmap_update() an argument (a pmap_t) so that it knows which pmap it should be updating.
1.51	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).
1.50	26-Mar-2001	pk	pmap_release(), pmap_pinit() and the `pm_regstore' field are obsolete.
1.49	01-Mar-2001	pk	branches: 1.49.2; Drop the managed() macro; it is no longer used. State the intended use of the vm_{first,last,num}_phys variables that are still exported from pmap.c.
1.48	31-May-2000	pk	Remove obsolete function declarations. Move switchexit() to cpu.h
1.47	31-May-2000	pk	Fix a couple of typos.
1.46	01-May-2000	pk	branches: 1.46.2; Implement HyperSPARC specific pmap_{zero,copy}_page functions.
1.45	30-Apr-2000	pk	Allow for CPU specific page clear and page copy functions.
1.44	13-Mar-2000	soren	Fix doubled 'the's in comments.
1.43	14-Nov-1999	thorpej	Update for pmap API change.
1.42	04-Oct-1999	pk	branches: 1.42.2; 1.42.4; 1.42.8; Each process (i.e. each `pmap') needs a region table for each CPU. Implement this by making the fields `pm_reg_ptp' and `pm_reg_ptp_pa' pointers to an array of `ncpu' region table pointers and corresponding physical addresses. This is a somewhat unfortunate side effect of having the per-CPU data addressable by the same virtual address on each CPU.
1.41	12-Sep-1999	chs	eliminate the PMAP_NEW option by making it required for all ports. ports which previously had no support for PMAP_NEW now implement the pmap_k* interfaces as wrappers around the non-k versions.
1.40	08-Jul-1999	thorpej	Change the pmap_extract() interface to: boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *); This makes it possible for the pmap to map physical address 0.
1.39	28-Jun-1999	pk	mmu_pagein() prototype: change address argument to `vaddr_t'.
1.38	17-Jun-1999	thorpej	pmap_change_wiring() -> pmap_unwire().
1.37	17-Jun-1999	thorpej	Remove pmap_pageable(); no pmap implements it, and it is not really useful, because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire()) communicate the information in greater detail.
1.36	26-Mar-1999	mycroft	branches: 1.36.2; 1.36.4; 1.36.6; Changes for modified pmap_enter() API: * Map the message buffer with access_type = VM_PROT_READ\|VM_PROT_WRITE `just because'. * Map the file system buffers with access_type = VM_PROT_READ\|VM_PROT_WRITE to avoid possible problems with pagemove(). * Do not use VM_PROT_EXEC with either of the above. * Map pages for /dev/mem with access_type = prot. Also, DO NOT use pmap_kenter() for this, as we DO NOT want to lose modification information. * Map pages in dumpsys() with VM_PROT_READ. * Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with access_type = prot. * For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use access_type = 0. This should probably be revisited.
1.35	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).
1.34	21-Aug-1998	pk	Convert to [pv]addr_t & [pv]size_t.
1.33	02-Mar-1998	fvdl	Make this compile again.
1.32	08-Jan-1998	thorpej	Update a comment relative to the vm_bootstrap_steal_memory() change, and don't include pmap_free_pages() or pmap_next_page() in the new non-contig case.
1.31	02-Jan-1998	thorpej	Implement pmap_activate().
1.30	04-Aug-1997	pk	Prototype pmap_writetext().
1.29	06-Jul-1997	pk	branches: 1.29.2; Follow lock changes (DEBUG => LOCKDEBUG).
1.28	06-Jul-1997	pk	Adjust for generic lock changes.
1.27	28-Jun-1997	pk	Remove __VM_PMAP_HACK.
1.26	24-May-1997	pk	Define macros for encoding I/O space bits into the physical address passed to pmap_enter().
1.25	16-May-1997	gwr	Add #define __VM_PMAP_HACK as a temporary measure.
1.24	27-May-1996	pk	prototype mmu_pagein4m() #if DEBUG is on.
1.23	27-May-1996	pk	No longer need to call mmu_pagein() through a pointer.
1.22	20-May-1996	thorpej	branches: 1.22.4; RCS Id police.
1.21	16-May-1996	abrown	Copyright police (s/Harvard University/Harvard College/).
1.20	31-Mar-1996	pk	Add SRMMU/sun4m support. Size and layout of `struct pmap' has changed.
1.19	14-Mar-1996	christos	Add missing prototypes and fix the fp struct for svr4.
1.18	28-Feb-1996	gwr	update PMAP_PREFER
1.17	05-Jul-1995	pk	Prototype pmap_dumpsize() and pmap_dumpmmu().
1.16	13-Apr-1995	pk	Make size of `struct pmap' independent of `MMU3_L', so libkvm is usable on all machines.
1.15	13-Apr-1995	pk	3-level MMU changes: software MMU data structures now display a VM model consisting of `regions', `segments' and `page maps'.
1.14	10-Apr-1995	mycroft	Bring back pmap_kernel(), for now always inlined as a pointer to kernel_pmap_store.
1.13	28-Mar-1995	jtc	KERNEL -> _KERNEL
1.12	10-Mar-1995	pk	Prototype for pmap_pa_exists().
1.11	10-Jan-1995	pk	pmap_init() already declared elsewhere.
1.10	09-Jan-1995	mycroft	Validate /dev/mem addresses again.

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.

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.

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.

1.17	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.

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.

1.9	08-May-1995	pk	#define VA_INHOLE() - to test a VA for being in an MMU hole (and PG_VSHIFT should 29).
1.8	13-Apr-1995	pk	3-level MMU changes: software MMU data structures now display a VM model consisting of `regions', `segments' and `page maps'.

1.16	14-Sep-2020	kamil	Switch from register_t to unsigned long int Removes dependency on _KERNTYPES.
1.15	24-Dec-2019	kamil	Introduce PT_LWPSTATUS + PT_LWPNEXT, obsolete PT_LWPINFO PT_LWPINFO is a legacy ptrace(2) operation that was originally intended to retrieve the thread (LWP) information inside a traced process. It has a number of flaws and is confused with PT_LWPINFO from FreeBSD. PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename, removal of pl_event) and introduces new features: signal context (pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address (pl_private). The private pointer was so far missing information for a debugger. PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific information, so far missed in the core(5) files. PT_LWPSTATUS retrieves LWP information for the prompted thread. PT_LWPNEXT retrieves LWP information for the next thread, borrowing the semantics from NetBSD specific PT_LWPINFO. PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for the foreseeable future, without plans of removing it. Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT. Keep ATF tests for PT_LWPINFO. Switch GDB to new API. Proposed on tech-kern@.
1.14	18-Jun-2019	kamil	Introduce PTRACE_REG_FP() a helper macro to retrieve the frame pointer The macro is dummy for ia64 (the FP register is unknown and can change freely) and sparc/sparc64 (not stored in struct reg).
1.13	17-Apr-2019	martin	Make the illegal instruction macro safe, so the compiler does not fear it would be an illegal instruction when compiling with certain cpu options.
1.12	16-Apr-2019	martin	Add PTRACE_ILLEGAL_ASM
1.11	12-Apr-2017	kamil	branches: 1.11.12; Add new macro PTRACE_BREAKPOINT_ASM in <sys/ptrace.h> MD part This macro ships with a MD-specific assembly instruction triggering a software breakpoint. Missing instruction for powerpc targets. This code is used in ATF tests (lib/libc/sys/t_ptrace_wait). Original patch by Nick Hudson, thanks!
1.10	25-Nov-2016	christos	branches: 1.10.2; cast to register_t because not all 'struct reg' members are the right type.

1.24	26-Oct-2021	christos	Merge all MD __sigaction14_sigtramp.c copies into one: - sparc and sparc64 were not using version 0 sigcontext when there were no arguments in the signal version. This was probably a bug. - vax is using +1 the version numbers of the other archs. - Only hppa was defining __LIBC12_SOURCE__ so it was getting a working sigcontext before. all the other ports that supported sigcontext had the compat code disabled. [pointed out by thorpej, thanks!] If we want to remove sigcontext support from userland at least now there is less work to do so.

1.11	28-Apr-2003	bjh21	branches: 1.11.2; Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

1.8.12.3	16-Jan-2003	martin	Fix typo.
1.8.12.2	16-Jan-2003	thorpej	* Include <sys/sigtypes.h> rather than <sys/signal.h> in <sys/ucontext.h>. * Define _UCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_UCONTEXT() macros for converting a ucontext -> sigcontext and back again. These macros in turn use machine-dependent macros _MCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_MCONTEXT() provided by <machine/signal.h>. The conversion process is not 100% accurate, but should be close enough. Also note that the mcontext conversion may not be enough for all platforms (m68k is a good example of this). These macros should be used only if you really know what you're doing.

Busy time is now stored as a timeval, and transfer count in bytes. - Storage for disklabels is now dynamically allocated, so that the size of the disk structure is not machine-dependent. - Several new functions for attaching and detaching disks, and handling metrics calculation. Old-style instrumentation is still supported in drivers that did it before. However, old-style instrumentation is being deprecated, and will go away once the userland utilities are updated for the new framework. For usage and architectural details, see the forthcoming disk(9) manual page.

1.73	20-Mar-2023	martin	__HAVE_HASHLOCKED_ATOMICS needs to be visible to userland
1.72	30-Jul-2022	riastradh	sys/atomic.h: Fix atomic_store_* on sparcv7, sparcv8. These did not cooperate with the hash-locked scheme of the other atomic operations, with the effect that, for instance, a typical naive spin lock based on atomic_, volatile unsigned locked = 0; lock() { while (atomic_swap_uint(&locked, 1)) continue; membar_acquire(); } unlock() { membar_release(); atomic_store_relaxed(&locked, 0); } would fail to achieve mutual exclusion. For this case, we need to use atomic_swap_ (or, for 8- or 16-bit objects, atomic_cas_32 loops, since there is no atomic_swap_8 or atomic_swap_16). The new machine/types.h macro __HAVE_HASHLOCKED_ATOMICS says whether these contortions are necessary. Note that this _requires_ the use of atomic_store_(p, v), not regular stores p = v, to work with the r/m/w atomic operations.

1.64	06-Oct-2015	martin	Do not use #ifdef SUN4U when testing for cpu features of post-v8 CPUs, it is not good for SUN4V-only kernels. Instead use __sparc_v9__ (which is also defined by the sparc compiler when called with cpu=ultrasparc). ok: mrg@
1.63	27-Aug-2015	pooka	Fix PTHREAD_FOO_INITIALIZER for C++ by not using volatile in the relevant pthread types in C++ builds, attempt 2. The problem with attempt 1 was making assumptions of what the MD __cpu_simple_lock_t (declared volatile) looks like. To get a same type except non-volatile, we change the MD type to __cpu_simple_lock_nv_t and typedef __cpu_simple_lock_t as a volatile __cpu_simple_lock_nv_t. IMO, __cpu_simple_lock_t should not be volatile at all, but changing it now is too risky. Fixes at least Rumprun w/ gcc 5.1/5.2. Furthermore, the mpd application (and possibly others) will no longer require NetBSD-specific patches. Tested: build.sh for i386, Rumprun for x86_64 w/ gcc 5.2. Based on the patch from Christos in lib/49989.

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.

1.56	24-Feb-2011	joerg	Allow storing and receiving the LWP private pointer via ucontext_t on all platforms except VAX and IA64. Add fast access via register for AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace the stack based pthread_self(). Implement skeleton support for Alpha, HPPA, PowerPC, SPARC and SPARC64, but leave it disabled. Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in machine/types.h and a corresponding __lwp_getprivate_fast in machine/mcontext.h. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.

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.

This is true of sparc, so define __HAVE_NWSCONS, and remove the code in pckbc_machdep_cnattach() that was conditional on its not being defined and that is no longer needed (since with __HAVE_NWSCONS, pckbc_cnattach() will call pckbd_cnattach() itself if necessary).

OKed by acorn26, hpcarm and sparc port masters.
1.32	28-Apr-2003	bjh21	branches: 1.32.2; Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) \|\| !defined(_POSIX_C_SOURCE) \|\| !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

1.10	23-Nov-2019	ad	Looks like sparc clears want_ast with interrupts enabled, so check+clear it and call mi_userret() in a loop.
1.9	21-Nov-2019	ad	mi_userret(): take care of calling preempt(), set spc_curpriority directly, and remove MD code that does the same.

1.7	17-Oct-2007	garbled	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.

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.

1.27	29-Apr-2001	thorpej	Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this data when pages are initialized by UVM. 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.

1.40.2.1	23-Feb-2010	uebayasi	Convert all VM_MDPAGE_INIT()'s to take struct vm_page_md * and paddr_t.
