Revision	Date	Author	Comments
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	12-Jul-2018	maxv	branches: 1.38.36; 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.
1.37	24-Dec-2015	christos	branches: 1.37.16; 1.37.18; fenv for m68k
1.36	19-Nov-2011	isaki	branches: 1.36.10; 1.36.28; Obsolete pow(4) and rtcalarm(8). Discussed in port-x68k@. Probably the combination of pow(4) ioctl and rtcalarm(8) does not work for a long time, and nobody uses them. I'll rewrite a part about power switch handler as a new device.
1.35	21-Jul-2011	joerg	branches: 1.35.2; machine/stdarg.h and machine/varargs.h are gone
1.34	11-Jul-2011	joerg	Sort
1.33	01-Jun-2008	isaki	Remove x68k/include/pci_machdep.h. x68k does not have PCI-bus, and no one refers to it.
1.32	11-Mar-2007	isaki	branches: 1.32.38; 1.32.40; 1.32.42; 1.32.44; Stop installing <machine/intr.h> on x68k. Suggested by simonb@ and tsutsui@.
1.31	09-Feb-2007	ad	branches: 1.31.2; 1.31.6; Merge newlock2 to head.
1.30	26-Jul-2006	drochner	branches: 1.30.4; don't install <machine/db_machdep.h>, this is kernel only
1.29	11-Dec-2005	christos	branches: 1.29.4; 1.29.8; merge ktrace-lwp.
1.28	12-May-2004	minoura	branches: 1.28.12; Populate kbdmap-related definitions to the userland. Also g/c unused ioctls. Pointed out by he.
1.27	08-May-2004	kleink	Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.
1.26	08-May-2004	minoura	An unexported header file was #included from an exported header file. Introduce <machine/opmreg.h> and move some definitions useful to userland progs.
1.25	18-Jan-2003	thorpej	branches: 1.25.2; Merge the nathanw_sa branch.
1.24	26-Nov-2002	lukem	Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.
1.23	14-Oct-2002	isaki	Sort.
1.22	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.
1.21	24-Mar-2002	isaki	branches: 1.21.2; bsd_audioio.h was obsolated by vs0
1.20	28-Nov-2001	kleink	No point in installing svr4_machdep.h.
1.19	12-Jun-2001	minoura	branches: 1.19.2; 1.19.8; Remove unneeded whitespace.
1.18	15-Apr-2001	kleink	Add definitions of C99 integer format conversion macros. XXX Fastest minimum-width integer types haven't been decided upon yet.
1.17	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.
1.16	14-Apr-2001	kleink	Add definitions of C99 integer constant macros. Tidy Makefiles up a little.
1.15	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.
1.14	26-Jun-2000	kleink	branches: 1.14.2; Add <machine/int_types.h>, which provides namespace-pure definitions of exact-width integer types.
1.13	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>.
1.12	17-Mar-2000	tron	Install "machineendian_machdep.h".
1.11	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.
1.10	19-Apr-1999	kleink	branches: 1.10.2; Add COMPAT_SVR4 for m68k.
1.9	16-Mar-1999	minoura	branches: 1.9.4; Merged minoura_x68k_bus_h branch.
1.8	15-Mar-1999	minoura	Pullin m68k/ieee.h.
1.7	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.
1.6	14-Dec-1998	itohy	branches: 1.6.2; Added intr.h
1.5	01-Sep-1998	itohy	Added an include file on port dependent boot information.
1.4	07-Aug-1998	minoura	Moved parioctl.h to the system header directory.
1.3	06-Aug-1998	minoura	Moved grfioctl.h and iteioctl.h to the public include directory.
1.2	12-Jul-1998	veego	Add elf_machdep.h to the INCS list.
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	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.

1.20	19-Mar-2010	tsutsui	bus_space_write_region_N() should also take a const buffer.
1.19	19-Mar-2010	he	Constify the buffer pointer argument of the _bus_space_write_multi_<n> inline functions, so that this builds again. (Otherwise, ne2000.c driver would now fail to build.)
1.18	28-Apr-2008	martin	branches: 1.18.20; 1.18.22; Remove clause 3 and 4 from TNF licenses
1.17	04-Mar-2007	christos	branches: 1.17.40; 1.17.42; 1.17.44; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.16	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.
1.15	16-Feb-2006	perry	branches: 1.15.20; 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@.
1.14	11-Dec-2005	christos	branches: 1.14.2; 1.14.4; 1.14.6; merge ktrace-lwp.
1.13	09-Mar-2005	matt	branches: 1.13.4; 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.
1.12	18-Jan-2005	chs	branches: 1.12.2; de-__P, remove register, ansify.
1.11	15-Jun-2003	fvdl	branches: 1.11.2; 1.11.10; 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.
1.10	28-Jan-2003	kent	Introduce BUS_DMA_NOCACHE, and bus_dmamem_map() of i386 supports it.
1.9	11-Nov-2001	isaki	Support BUS_SPACE_MAP_SHIFTED_EVEN for bus_space_map(). Now BUS_SPACE_MAP_SHIFTED means BUS_SPACE_MAP_SHIFTED_ODD. It is needed for Nereid Ethernet.
1.8	19-Jul-2001	thorpej	branches: 1.8.4; 1.8.6; 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.
1.7	07-Mar-2001	thorpej	branches: 1.7.2; Add the BUS_DMA_STREAMING flag.
1.6	29-Jan-2001	itohy	branches: 1.6.2; Performance hack. Mainly for the Neptune-X Ethernet adaptor, and improves ftp(1) speed by ~10%. get: 219 KB/s -> 246 KB/s put: 226 KB/s -> 247 KB/s (X68030, MC68030 25MHz)
1.5	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.
1.4	25-Jan-2000	drochner	branches: 1.4.4; define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that device accesses are idempotent (but should not be cached by the CPU)
1.3	23-Mar-1999	drochner	branches: 1.3.8; 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)
1.2	16-Mar-1999	minoura	Merged minoura_x68k_bus_h branch.
1.1	23-Dec-1998	minoura	branches: 1.1.2; file bus.h was initially added on branch minoura_x68k_bus_h.
1.1.2.4	14-Mar-1999	minoura	Use a single (inline) function instead of refering the bus_space switch.
1.1.2.3	13-Feb-1999	minoura	Implemented BUS_SPACE_MAP_SHIFTED. Some of the devices are mapped only on the odd addresses for hardware simplicity. To share drivers with other platforms, this should be made transparent through the bus_space layer.
1.1.2.2	30-Jan-1999	minoura	Added DMAC driver.
1.1.2.1	23-Dec-1998	minoura	First import of bus_space implementation for x68k port.

1.1	05-May-1996	oki	branches: 1.1.1; Initial revision
1.1.1.1	05-May-1996	oki	NetBSD/x68k, by Masaru Oki.
1.67	20-Jan-2024	thorpej	Largely unify the <machine/cpu.h> headers on the m68k platforms.
1.66	19-Jan-2024	thorpej	Switch the x68k port to use the same clockframe layout as the other m68k ports.
1.65	18-Jan-2024	thorpej	Make the M68K_MMU_* defines real kernel options, available in opt_m68k_arch.h. For 68030, 68040, and 68060, infer M68K_MMU_MOTOROLA. For 68010 and 68020, it must be an explicit option (set in std.${MACHINE} or, in the case of hp300, inferred from the specific model option).
1.64	09-Jan-2024	thorpej	Remove duplicated / slightly-tweaked loadustp() (load user segment table) routines from all of the m68k ports using the shared pmap. Instead, in pmap_init(), set up a function pointer to the appropriate mmu_load_urp*() function in mmu_subr.s.
1.63	07-Jan-2024	isaki	TAB/space/indent cleanup.
1.62	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().
1.61	18-Feb-2019	thorpej	Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port. Tested by rjs@ on a Quadra 950. (Thanks!)
1.60	22-Aug-2018	msaitoh	- Cleanup for dynamic sysctl: - Remove unused _NAMES macros for sysctl. - Remove unused _MAXID for sysctls. - Move CTL_MACHDEP sysctl definitions for m68k into m68k/include/cpu.h and use them on all m68k machines.
1.59	17-Dec-2016	flxd	branches: 1.59.14; 1.59.16; Fix typo "one the" and architecture where appropriate.
1.58	31-Jul-2014	isaki	branches: 1.58.4; 1.58.8; Remove the variable not used anymore. sync with x68k/pmap_bootstrap.c,v 1.21 (in 2001).
1.57	19-Oct-2013	christos	branches: 1.57.2; make cpu_need_resched() macros consistent; __USE flags
1.56	02-Feb-2012	tsutsui	branches: 1.56.6; 1.56.10; Always include <m68k/cpu.h> (i.e. outside #if defined(_KERNEL)) for crash(8) as amiga and sun3. There are _KERNEL protections in it. Briefly tested by "build.sh -m news68k -U build". Further possible botch will be fixed later.
1.55	15-Nov-2011	tsutsui	branches: 1.55.4; Merge copy-and-pasted fpu_probe() function (to share it among more m68k ports). Tested on TT030, Sun3/80, and X68030.
1.54	16-May-2011	tsutsui	branches: 1.54.4; - merge and move pasted m68k MD setreg() functions into m68k/m68k_machdep.c - move m68881_save() and m68881_restore() declarations into <m68k/m68k.h> Briefly tested and no obvious breakage on atari, sun3, and x68k.
1.53	12-May-2011	tsutsui	Make intiobase and intiolimit unsigned for consistency.
1.52	08-Feb-2011	rmind	Remove clause 3 (UCB advertising clause) from the University of Utah copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks! Also, merge UCB and Utah copyright texts back into one, as they originally were. Extra verification by snj@.
1.51	22-Dec-2010	matt	branches: 1.51.2; 1.51.4; Collect cpu_info and friends and move to m68k/include/cpu.h Add a define __HAVE_CPU_DATA_FIRST which means that cpu_data is the first member in struct cpu_info.
1.50	06-Jun-2010	mrg	fix PR 6724 - convert m68k options to defflag's. this means that M680[12346] are now available from opt_m68k_arch.h. FPSP meantioned in the PR has already been fixed, and i could not find any more. i built these kernels to ensure i did not break their builds: amiga: GENERIC DRACO atari: HADES FALCON MILAN-PCIIDE mac68k: GENERIC sun2: GENERIC sun3: GENERIC GENERIC3X cesfic: attempted GENERIC, does not build due to lack of machine/bus.h hp300: GENERIC luna68k: GENERIC mvme68k: GENERIC news68k: GENERIC next68k: GENERIC x68k: GENERIC
1.49	21-Oct-2009	rmind	branches: 1.49.2; 1.49.4; 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>.
1.48	17-Jan-2009	isaki	Purge x68k_config_found() to simplify consinit routine. config_console() calls initialization of grf, ite, mfp directly, instead of tracing special device tree with an emulated 'struct device'.
1.47	18-Dec-2008	isaki	Sync with other m68k ports. - Remove PHYS_IODEV, PHYS_INTIODEV. These are real copy of INTIOBASE. - Define IIOV() (and IIOP()) and use it, rather than INTIO_ADDR().
1.46	18-Dec-2008	isaki	Move external decl. of intiobase: dev/intiovar.h -> include/cpu.h Move definition of intiobase: x68k/pmap_bootstrap.c -> x68k/locore.s These synchronize code with other m68k ports.
1.45	27-Feb-2008	xtraeme	branches: 1.45.4; 1.45.12; Remove CTL_MACHDEP_NAMES, it's not used anywhere. Ok by martin@.
1.44	17-Oct-2007	garbled	branches: 1.44.12; 1.44.16; 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.
1.43	04-Aug-2007	ad	branches: 1.43.2; Add ci_cpuid where it's missing.
1.42	21-May-2007	tsutsui	branches: 1.42.2; 1.42.4; 1.42.8; Move declarations of m68k common functions from <machine/cpu.h> to <m68k/m68k.h>. While here, remove some obsolete function decls.
1.41	20-May-2007	mhitch	Add missing call to lwp_startup() in lwp_trampoline() (which was renamed from proc_trampoline to match the other ports). A DIAGNOSTIC kernel will now boot and run. LOCKDEBUG still doesn't work yet. Also, my amiga no longer loses time.
1.40	19-May-2007	isaki	Use do { } while (0) to macro.
1.39	19-May-2007	isaki	Adapt to the merge of yamt-idlelwp branch. tested on my X68030.
1.38	04-Mar-2007	christos	branches: 1.38.2; 1.38.4; 1.38.10; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.37	16-Feb-2007	ad	branches: 1.37.2; Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts via a soft interrupt. In the near future, softclock will be run from process context.
1.36	09-Feb-2007	ad	Merge newlock2 to head.
1.35	11-Dec-2005	christos	branches: 1.35.20; merge ktrace-lwp.
1.34	13-Jun-2005	he	branches: 1.34.2; Change the signature of badaddr() and badbaddr() from taking a caddr_t to taking a volatile void*. This gets rid of a number of casts to make this compile under -Wcast-qual. Add some volatiles and consts in other places to make this build under -Wcast-qual. Also rename a few variables to make this build under -Wshadow. Also get rid of duplicated declarations of badaddr() and badbaddr() in machdep.c, they're already there from <machine/cpu.h>.
1.33	18-Jan-2005	chs	de-__P, remove register, ansify.
1.32	26-Sep-2004	yamt	branches: 1.32.4; don't expose cpu_info to userland.
1.31	22-Sep-2004	yamt	move some per-cpu data definitions to MI place so that they can be modified without touching all ports. discussed on tech-kern@.
1.30	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
1.29	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.
1.28	18-Jan-2003	thorpej	branches: 1.28.2; Merge the nathanw_sa branch.
1.27	28-Oct-2002	chs	untangle includes a bit: don't include cpu.h in pmap.h, nor cacheops.h in cpu.h. instead, include cpu.h and cacheops.h in just those .c files that need them.
1.26	30-May-2001	mrg	branches: 1.26.8; use _KERNEL_OPT
1.25	19-Dec-2000	scw	branches: 1.25.2; Unification of the m68k syscall() function.
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	26-May-2000	thorpej	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.
1.22	23-Apr-2000	minoura	Do not include opt_m680x0 in LKM.
1.21	18-Apr-2000	minoura	defopt M680[2346]0.
1.20	23-Sep-1999	minoura	branches: 1.20.2; Use m68k common cacheops.c.
1.19	10-Aug-1999	thorpej	Define cpu_number() as discussed on tech-smp.
1.18	05-May-1999	minoura	Use mvme68k-derived delay routine. Now that we support various models, the old constant-loop delay routine may cause problems.
1.17	24-Mar-1999	minoura	branches: 1.17.2; 1.17.4; 1.17.6; Shut up gcc -Wall.
1.16	16-Mar-1999	minoura	Merged minoura_x68k_bus_h branch.
1.15	26-Feb-1999	is	synchronize types, and s/curproc/p/ in one forgotten place
1.14	26-Feb-1999	is	x68k specific part of fix for PR 6152
1.13	13-Dec-1998	minoura	branches: 1.13.2; Splitted out the interrupt handling code to a separate file. Disallow getting down the interrupt level by splXX.
1.12	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.
1.11	07-Oct-1998	thorpej	Oops, back out a buglet I didn't intend to commit in the last change.
1.10	06-Oct-1998	thorpej	configure() prototype is in <sys/device.h>
1.9	22-Aug-1998	minoura	Eliminated vm_offset_t and vm_size_t.
1.8	13-Feb-1998	scottr	Avoid declaring the "astpending" and "want_resched" globals in cpu.h, as this breaks C++ code that happens to indirectly include this header. Both Matthias Scheler and I noticed this, independently. This problem notably does not affect the atari and sun3/sun3x ports, which have already implemented a similar solution.
1.7	26-Oct-1997	is	Make these compile after m68k/m68k.h 1.4->1.5.
1.6	10-Oct-1997	oki	Add prototypes.
1.5	03-Feb-1997	oki	branches: 1.5.8; Remove #ifdef GENERIC ... #endif
1.4	08-Jan-1997	oki	Add fpu_probe prototype.
1.3	11-Sep-1996	thorpej	Use <m68k/cpu.h>.
1.2	21-May-1996	oki	Some cleanup. - Add missing return-type of function. - Add missing prototype. - some gcc -Wall printf warning.

1.3	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.

1.6	30-Aug-2011	bouyer	Add getlabelusesmbr(), as proposed in http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html This is used by disk tools such as disklabel(8) to dynamically decide is the undelyling platform uses a disklabel-in-mbr-partition or not (instead of using a compile-time list of ports). getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the machdep #define LABELUSESMBR. For evbmips, make LABELUSESMBR 1 if the platform uses pmon as bootloader, and 0 (the previous value) otherwise.
1.5	23-Nov-2009	pooka	If cpu_disklabel includes struct dkbad, define __HAVE_DISKLABEL_DKBAD. This allows use of subr_disk_mbr on all archs. Default to it for the rump disk component. No functional change for regular kernels. (The other option would've been to include dkbad in disklabels everywhere, but arguably this approach has less possible side-effects, especially given that wedges and related magic will take over the world any second now).
1.4	11-Dec-2005	christos	branches: 1.4.78; merge ktrace-lwp.
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.

See sun68k/sun68k/isr.c. Tested on various m68k platforms, but NOT Sun2. In any case, at least Sun2 compiles now.

1.3	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.
1.2	16-Mar-1999	minoura	Merged minoura_x68k_bus_h branch.

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.

Add xxboot_?fsv?. Change to the 2-clauses license. Tweak SUBDIR build order and add comments about each dir. Fix a bug in check_getchar() (called from awaitkey_1sec()). It didn't clear input key data when non ASCII keys (CTRL, OPT.1 etc) were pressed so it couldn't detect further key inputs and "any other key for boot menu" interrupt during boot didn't work in that case. The problem was tracked by Y.Sugahara, and tested on X68030 and XM6i by me. Bump version to denote check_getchar() bug fix. First cut at x68k network bootloader via NE2000 on Neptune-X and Nereid. Written by isaki@ back in 2003 based on x86's NE2000 netboot, and misc debug and improvements by tsutsui@ and Y.Sugahara. Tested on XM6i (emulating Nereid Ethernet) and X68030 + Neptune-X by me, also on X68030 + Nereid and X68000 PRO-II + Xellent30 + Nereid by isaki@. Note: - X680x0 IPLROM doesn't support bootstrap from Neptune-X or Nereid, so this network bootloader needs to be loaded from floppy or harddisk. - Currently netboot support is not merged into the secondary Multi-boot (/usr/mdec/boot) due to size restriction. - Primary loaders assumes that the secondary bootloader name is /boot, so /usr/mdec/netboot needs to be installed as /boot into the target bootstrap device. Add new /usr/mdec/netboot. Check lp->d_npartitions before calling dkcksum() (which is in src/sbin/disklabel/dkcksum.c) because it doesn't check range and could cause coredump during installboot against floppy that includes garbage in LABELSECTOR.

1.1	29-Apr-2000	thorpej	branches: 1.1.6; 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>.

Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.

1.14.2.1	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.

1.23.4.3	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).
1.23.4.2	18-Nov-2001	scw	MD Scheduler Activation bits for X68k. Compile-tested only.

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.

1.4	20-Dec-2008	isaki	branches: 1.4.14; x68k pow(4) now uses MI sysmon_pswitch framework. suggested by tsutsui@. - Make MD poffd(8) retire, and use MI powerd(8) instead of it. - Make /dev/pow1 retire, because nobody holds /dev/pow0 any longer. Use /dev/pow0 for pow(4) ioctl. - POWIOCSSIGNAL ioctl which is for poffd(8) is also obsoleted.

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.

1.41	08-Feb-2025	tsutsui	Bump DFLSSIZ from 512KB to 2MB on all hp300 pmap m68k ports. Some modern applications could require 512KB buffer on stack and no particular comment on port-m68k@: https://mail-index.netbsd.org/port-m68k/2025/02/02/msg000893.html
1.40	01-Feb-2020	tsutsui	branches: 1.40.30; Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3). Background: - All m68k ports have fixed PAGE_SIZE value in their kernels, but each port uses different PAGE_SIZE value (4096 or 8192) due to historical reasons. - Currently module(7) binaries are built per each port so all m68k kernel sources don't support run-time variable PAGE_SIZE. - MI <uvm/uvm_param.h> assumes that the port supports a variable PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE are defined and they have different values. - On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h for internal optimization. - m68k ports share userland binaries (especially pkgsrc binaries) among all ports, so we need to define MAX_PAGE_SHIFT as 13 to support m68k ports where PAGE_SIZE==8192. (though this would affect only if static binaries built on 4k page hosts are executed on 8k page hosts) To solve these inconsistency on PAGE_SIZE definitions, we should have an independent PAGE_SIZE related definitions for userland, but it requires major reorganization. For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case. Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@: https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035 https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954 Should be pulled up to netbsd-9.

1.36	25-Jan-2014	tsutsui	branches: 1.36.6; 1.36.10; 1.36.14; Increase VM_KERNEL_PT_PAGES from 2 to 4 for x68k. X68030 with 8MB or 12MB RAM (which is default for most X68030s) now gets "pmap_enter_ptpage: can't get KPT page" panic again with VM_KERNEL_PT_PAGES=2 while it works with >=14MB. 3 is enough to boot for now, but I also add a spare. I guess this is because the post netbsd-6 vmem(9) bootstrap changes require more kernel memory before MD pmap_init(). Note1: netbsd-6 (which also pulls physmem detection changes that affect nptpages) doesn't have this problem. Note2: other hp300 pmap based m68k ports might have the same issue, but at least 12MB luna68k works with VM_KERNEL_PT_PAGES=2 so I think it depends on kernel size and/or iomapsize.
1.35	21-Jan-2012	tsutsui	branches: 1.35.6; 1.35.10; Give higher priority to faster local memory on uvm_page_physload(). Tested by Y.Sugahara on his 060turbo with 128MB local memory and this improved even simple benchmark. Ok'ed by isaki@.

The previous values might be derived from (0 - UPAGES * PAGE_SIZE), but there is no particular reason to have different values among m68k ports.

1.30	26-Aug-2009	thorpej	Minor tweak to the pv_table management in the Hibler-derived m68k pmaps: The head of the list is now a pv_header, which contains the first pv_entry as well as a 16-bit attributes field (replaces the pmap_attributes array plus the pv_entry::pv_flags field) as a 16-bit count of caller-specified cache-inhibited mappings. Tested on hp300 (shared pmap_motorola.c), changes to atari and amiga copies are purely mechanical.

1.20	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.

Background: - All m68k ports have fixed PAGE_SIZE value in their kernels, but each port uses different PAGE_SIZE value (4096 or 8192) due to historical reasons. - Currently module(7) binaries are built per each port so all m68k kernel sources don't support run-time variable PAGE_SIZE. - MI <uvm/uvm_param.h> assumes that the port supports a variable PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE are defined and they have different values. - On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h for internal optimization. - m68k ports share userland binaries (especially pkgsrc binaries) among all ports, so we need to define MAX_PAGE_SHIFT as 13 to support m68k ports where PAGE_SIZE==8192. (though this would affect only if static binaries built on 4k page hosts are executed on 8k page hosts) To solve these inconsistency on PAGE_SIZE definitions, we should have an independent PAGE_SIZE related definitions for userland, but it requires major reorganization. For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case. Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@: https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035 https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954 Should be pulled up to netbsd-9.
