Revision	Date	Author	Comments
1.38	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.
1.37	04-Nov-2024	christos	Undo previous lwp.h change.
1.36	03-Nov-2024	christos	Split __lwp_getprivate_fast and __lwp_*tcb from mcontext.h into a separate lwp.h file.
1.35	14-Jan-2024	thorpej	branches: 1.35.2; Add a common m68k interrupt dispatch implementation.
1.34	27-Dec-2023	thorpej	Add a header file for 68030-specific MMU definitions, specifically the Transparent Translation registers, that do not exist on the 68851. A big comment at the top of the file describes the differences between the 68851 and the 68030's MMU.
1.33	27-Dec-2023	thorpej	Add new headers that describe the 68851 (and 68030) MMU and 68040 (and 68060) MMU structures using names that more closely align with Motorola's documentation. The definitions here automagically adapt to 4K or 8K pages, based on the value of PGSHIFT, which must be a compile-time constant.
1.32	01-Feb-2020	tsutsui	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.
1.31	22-Aug-2018	msaitoh	branches: 1.31.4; 1.31.6; - 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.
1.30	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.
1.29	24-Dec-2015	christos	branches: 1.29.16; 1.29.18; fenv for m68k
1.28	17-Jul-2013	matt	branches: 1.28.8; Export fpreg.h for libc
1.27	17-Jul-2011	joerg	branches: 1.27.2; 1.27.12; 1.27.16; Retire varargs.h support. Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.
1.26	09-Feb-2007	ad	Merge newlock2 to head.
1.25	26-Jul-2006	drochner	branches: 1.25.4; don't install <machine/db_machdep.h>, this is kernel only
1.24	13-Apr-2006	oster	Populate /usr/include/m68k with both pmap_motorola.h and pte_motorola.h. /usr/include/m68k/pmap.h expects to find pmap_motorola.h, and /usr/include/machine/pte.h wants pte_motorola.h.
1.23	11-Dec-2005	christos	branches: 1.23.4; 1.23.6; 1.23.8; 1.23.10; 1.23.12; merge ktrace-lwp.
1.22	08-May-2004	kleink	branches: 1.22.12; Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.
1.21	22-Sep-2003	cl	SA_SIGINFO support for m68k
1.20	17-Jan-2003	thorpej	branches: 1.20.2; Merge the nathanw_sa branch.
1.19	26-Nov-2002	lukem	Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.
1.18	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.
1.17	13-Jul-2002	scw	m68k syscall rototill: - Switch all m68k-based ports over to __HAVE_SYSCALL_INTERN. - Add systrace glue. - Define struct mdproc in <m68k/proc.h> instead of <machine/proc.h>. (They were all defined exactly the same anyway, other than a couple of the MDP_* flags.)
1.16	10-Apr-2002	briggs	branches: 1.16.2; bus_dma(9) pulled pretty much verbatim from next68k.
1.15	28-Nov-2001	kleink	No point in installing svr4_machdep.h.
1.14	15-Apr-2001	kleink	branches: 1.14.2; 1.14.8; Add definitions of C99 integer format conversion macros. XXX Fastest minimum-width integer types haven't been decided upon yet.
1.13	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.
1.12	14-Apr-2001	kleink	Add definitions of C99 integer constant macros. Tidy Makefiles up a little.
1.11	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.
1.10	06-Apr-2001	tsutsui	Install byte_swap.h on make includes.
1.9	26-Jun-2000	kleink	branches: 1.9.2; Add <machine/int_types.h>, which provides namespace-pure definitions of exact-width integer types.
1.8	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>.
1.7	17-Mar-2000	tron	Install "machineendian_machdep.h".
1.6	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.
1.5	19-Apr-1999	kleink	branches: 1.5.2; Add COMPAT_SVR4 for m68k.
1.4	09-Feb-1999	is	branches: 1.4.4; Provide a minimal instruction/data cache synchronization C binding. (The function has always been in the kernels as special trap #12). In response to PR 4951 by Hauke Fath.
1.3	15-Jan-1999	bouyer	Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.
1.2	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.

1.25	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. 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.
1.22	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.

1.20	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.

1.15	04-Oct-1997	thorpej	Copyright assigned to The NetBSD Foundation.
1.14	14-Jul-1997	thorpej	branches: 1.14.2; Don't have kernel vs. non-kernel versions of _ENTRY(); there's no reason to omit the .type directive in the kernel case.
1.13	24-Apr-1997	thorpej	Add several useful macros: - ENTRY_NOPROFILE() and ASENTRY_NOPROFILE(), similar to ENTRY() and ASENTRY(), but without the profiling prologue. - GLOBAL()/ASGLOBAL() and LOCAL()/ASLOCAL(), for defining global and local variables with C and ASM labels. - BSS()/ASBSS(), for defining items in the BSS segment, with C or ASM labels. - PANIC("panic message") - shorthand for calling panic() from assembly code. - VECTOR(), ASVECTOR(), VECTOR_UNUSED - shorthand for defining entries in the vector table. Also, change RCSID() to pad out the string to even boundary.
1.12	30-Nov-1996	jtc	PROF -> GPROF
1.11	24-Sep-1996	jtc	Added new macro _PROF_PROLOG which contains the code sequence needed to call mcount(). This is needed because the ``link a6,#0'' insn used trips up gcc's ANSI preprocessor (A # in a function-type macro must be followed by a macro argument). _PROF_PROLOG is also used in the i386 asm.h. Solaris' asm_linkage.h has a MCOUNT macro similar to _PROF_PROLOG except it expands to different code sequences based on whether a function is being compiled with "prof" or "gprof" instrumentation. I also discovered that the m68k ALTENTRY is very different than the implementation used by other NetBSD ports. Usually ALTENTRY simply provides an alternate function entry point. The m68k version takes a second argument and jumps inside the second function when profiling is enabled. The m68k behavior is similar to the ENTRY2 macro found in solaris. Providing ENTRY2 and changing all the code that uses ALTENTRY to use it would be a desirable change.

1.10	17-Oct-2007	garbled	branches: 1.10.16; 1.10.18; 1.10.20; 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.

1.14	17-Oct-2007	garbled	branches: 1.14.16; 1.14.18; 1.14.20; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.13	13-Jun-2007	he	branches: 1.13.10; Fix the 060 variants to not have conflicting definitions for the cache ops common to 060 and 040. Also remove the now-redundant definitions for the 060 variant which simply pointed to the 040 variants. This fixes the build of the mvme68k VME172 kernel.
1.12	08-Jun-2007	tsutsui	DCFA(), DCPA(), ICPL(), ICPP(), DCPL(), DCPP, DCFL(), and DCFP() cache ops are identical between M68040 and M68060 and they are not available on M68020 and M68030, so no need to check cputype even on multi CPU kernels and they can always be inlined.

1.4	04-Nov-1997	thorpej	Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>: - fix _C_LABEL so that it actually works. - make __RENAME use _C_LABEL. - fix __RENAME so that it expects an unquoted argument. - fix __indr_reference and __warn_references so that they supply their own final semicolon. - define __warn_references to nothing if not GNU C (required by the way it's used). 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.
1.3	22-Oct-1997	thorpej	Implement __RENAME() in <machine/cdefs.h>
1.2	23-Mar-1995	jtc	branches: 1.2.18; Changed name of __weak_reference() to __indr_reference(). They really are indirect references, and I want to add a real __weak_reference() macro to <machine/cdefs.h> soon.
1.1	19-Jan-1995	jtc	This file, which will be included by <sys/cdefs.h>, will contain macros such as __warn_references() and __weak_reference() which are actually machine dependant. 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".

1.25	28-Feb-2024	thorpej	Fix up the mac68k interrupt handlers to work with the new style common clockframe layout and remove the CLOCK_FORMAT0 work-around. As a nice side-effect, this also eliminates the super-sketchy stack unwinding used by rtclock_intr to get at the interrupt stack frame.
1.24	27-Feb-2024	nat	Use proper clockframe size for those platforms that require it. XXX This is a tempory measure, better to fix clock interrupts to take the common clockframe size. OK thorpej@.
1.23	20-Jan-2024	thorpej	What good are comments, really, if you can't have a little color? Add a note above CLKF_INTR() about why NetBSD will likely never switch to using the "master" stack for the kernel, and thus why the not-enabled version of CLKF_INTR() will never be enabled. (Adding the comment here, rather than just deleting the code, has value, I think, for future retrocomputing archeologists.)
1.22	20-Jan-2024	thorpej	Largely unify the <machine/cpu.h> headers on the m68k platforms.

1.20	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).
1.19	03-Jan-2024	thorpej	G/C some bit defs that are redundant with mmu_{51,40}.h
1.18	27-Dec-2023	thorpej	Re-factor the 680x0 Function Code definitions into their own separate file (as was done on the sun2/sun3 ports ages ago) and switch everyone to the common header.
1.17	01-Dec-2019	ad	Fix false sharing problems with cpu_info. Identified with tprof(8). This was a very nice win in my tests on a 48 CPU box. - Reorganise cpu_data slightly according to usage. - Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc). - On x86, put some items in their own cache lines according to usage, like the IPI bitmask and ci_want_resched.
1.16	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.
1.15	19-Sep-2011	rkujawa	branches: 1.15.52; 1.15.54; Move CACHELINE_* from bus_dma.c to cpu.h (needed for PCI configuration on amiga port).

1.12	22-Dec-2010	matt	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.

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.

1.15	21-Aug-1999	simonb	branches: 1.15.2; Include <sys/endian.h> after defining whether where are little- or big-endian. i386, pc532 and vax still include <machine/byte_swap.h> and define macros for the {n,h}to{h,n}*() functions. mips also defines some endian-independent assembly-code aliases for unaligned memory accesses.
1.14	24-Jan-1999	mycroft	Mark [hn]to[nh][ls]() with __const__, so they are subject to CSE.
1.13	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.

1.7	29-Mar-1996	briggs	Make NTOH[SL] and HTON[SL] (void) (x) instead of (x) to get around compiler warnings. Followed the lead set in the sparc port.

1.10	30-Oct-2024	riastradh	Sprinkle <sys/featuretest.h> where __SOURCE macros are consulted. Otherwise, the feature tests might come out wrong. For example, header files that check for _NETBSD_SOURCE won't get the default when no other __SOURCE macros are defined; header files that check for _POSIX_C_SOURCE might miss _XOPEN_SOURCE, which is supposed to imply a corresponding _POSIX_C_SOURCE.

1.27	07-Oct-2025	nat	Get the constants right for m68k softfloat. Now the libm test results are 0 failures, 1 expected failure.
1.26	04-Oct-2025	riastradh	x86, m68k <machine/float.h>: `Significand', not `mantissa'. The IEEE 754 standard uses `significand' and has since its first edition in 1985; Kahan and Knuth both use `significand' and explicitly reject `mantissa'; `significand' doesn't have a conflicting definition in logarithms; and in actual usage in the floating-point and numerical analysis literature, `significand' dominates. No functional change intended -- comment-only.
1.25	04-Oct-2025	nat	Increase LDL_MIN_EXP for softfloat. An exponent of zero(-16382) has special signifiance for softfloat. Found by atf-tests testing exponent values lower than the possible minimum.
1.24	30-Oct-2024	riastradh	Sprinkle <sys/featuretest.h> where __SOURCE macros are consulted. Otherwise, the feature tests might come out wrong. For example, header files that check for _NETBSD_SOURCE won't get the default when no other __SOURCE macros are defined; header files that check for _POSIX_C_SOURCE might miss _XOPEN_SOURCE, which is supposed to imply a corresponding _POSIX_C_SOURCE. PR lib/58752: various header files test _*_SOURCE macros but don't include sys/featuretest.h

In cpu_getcontext(), set the flag for all frame formats >= FMT4 such that cpu_setcontext() does The Right Thing with both user and kernel saved contexts. Make null FP frame detection work for the 68060's FPU, and ensure we always do at least an fsave/frestore when saving/restoring FPU regs. Both kernel and user-level get/set context calls pass all Nathan's context tests now.

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.

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.

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.

1.5	26-Sep-2003	nathanw	Move __cpu_simple_lock_t and __SIMPLELOCK_{UN,}LOCKED to machine/types.h so that they can be used in a namespace-friendly way.
1.4	17-Jan-2003	thorpej	branches: 1.4.2; Merge the nathanw_sa branch.
1.3	02-May-2000	thorpej	branches: 1.3.6; 1.3.14; On the m68k, the most efficient type for __cpu_simple_lock_t is an unsigned char, since that is what the `tas' instruction uses. While I'm here, implement the __cpu_simple_lock family of routines. Why? One, because they're easy. Two, so Steve can get master/slave MVME systems talking across the backplane. :-)
1.2	02-May-2000	thorpej	Let each platform typedef the new __cpu_simple_lock_t, which should be the most efficient type used for the atomic operations in the simplelock structure, and should also be __volatile.
1.1	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>.
1.3.14.2	25-Nov-2001	scw	Oops, got a bit too enthusiastic in the last change. Drop the volatile qualifier from __rv, otherwise the compiler generates even worse code than normal. ;)
1.3.14.1	25-Nov-2001	scw	In __cpu_simple_lock_try(), move the initialisation of __rv down into the asm code otherwise the compiler optimises it away...

The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe). Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.

1.10	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>
1.9	22-Nov-2011	joerg	branches: 1.9.42; Add TLS support for m68k.
1.8	24-Feb-2011	joerg	branches: 1.8.4; 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.

1.1.2.3	25-Nov-2001	scw	When restoring thread context, check the _UC_USER bit and DTRT when checking frame format and fpu saved state. The whole `full fpu state cannot be saved/restored from userland' needs more thought. XXX: _UC_USER really ought to be defined in <sys/ucontext.h> ...
1.1.2.2	21-Nov-2001	scw	Add an MD flag for uc_flags which indicates if the exception frame area of m68k's mcontext_t structure has valid contents. In cpu_getcontext(), set the flag for all frame formats >= FMT4 such that cpu_setcontext() does The Right Thing with both user and kernel saved contexts. Make null FP frame detection work for the 68060's FPU, and ensure we always do at least an fsave/frestore when saving/restoring FPU regs. Both kernel and user-level get/set context calls pass all Nathan's context tests now.

1.11	25-Aug-2021	thorpej	branches: 1.11.4; - In kern_mutex.c, if MUTEX_CAS() is not defined, define it in terms of atomic_cas_ulong(). - For arm, ia64, m68k, mips, or1k, riscv, vax: don't define our own MUTEX_CAS(), as they either use atomic_cas_ulong() or equivalent (atomic_cas_uint() on m68k). - For alpha and sparc64, don't define MUTEX_CAS() in terms of their own _lock_cas(), which has its own memory barriers; the call sites in kern_mutex.c already have the appropriate memory barrier calls. Thus, alpha and sparc64 can use default definition. - For sh3, don't define MUTEX_CAS() in terms of its own _lock_cas(); atomic_cas_ulong() is strong-aliased to _lock_cas(), therefore defining our own MUTEX_CAS() is redundant.

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.
1.24	31-May-2021	simonb	Include "opt_param.h" (ifdef _KERNEL_OPT) everywhere that MSGBUFSIZE is referenced since some sources include <machine/param.h>.
1.23	01-May-2020	isaki	branches: 1.23.6; 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
1.22	07-Jan-2019	jdolecek	branches: 1.22.4; move DEV_BSIZE, DEV_BSHIFT out of MD param.h, they are same on all ports also move BLKDEV_IOSIZE, MAXPHYS, but allow override since some ports have different value (powerpc uses NBPG for BLKDEV_IOSIZE, sun2/sun3 have lower MAXPHYS)
1.21	24-Jan-2012	christos	branches: 1.21.46; 1.21.48; Use and define ALIGN() ALIGN_POINTER() and STACK_ALIGN() consistently, and avoid definining them in 10 different places if not needed.
1.20	20-Jan-2012	joerg	Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions again. This was changed in sys/socket.h r1.51 to work around fallout from the IPv6 aux data migration. It broke the historic ABI on some platforms. This commit restores compatibility for netbsd32 code on such platforms and provides a template for future changes to the CMSG_* alignment. Revert PCC/Clang workarounds in postfix and tmux.
1.19	05-Mar-2011	matt	branches: 1.19.4; 1.19.8; If _KERNEL is not defined, force MACHINE to be "m68k". Userland should be using uname/sysctl to get this value.
1.18	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@.
1.17	08-Feb-2010	joerg	branches: 1.17.2; 1.17.4; 1.17.6; 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.
1.16	11-Dec-2009	tsutsui	branches: 1.16.2; Refactoring MD segment related definitions on m68k ports: - move macro SEGSHIFT, NBSEG, and SEGOFSET from <machine/param.h> to <m68k/pmap_motorola.h> where they should belong - also simplify NBSEG macro for both 020/030 and 040/060 cases - also move m68k_trunc_seg(), m68k_round_seg(), and m68k_seg_offset() (that use SEGOFSET) from <m68k/param.h> to <m68k/pmap_motorola.h> - add comments about each segment size value used on pmap_motorola implementation - add TIA_SIZE, TIA_SHIFT, TIB_SIZE, and TIB_SHIFT macro which can be used for ste/pte index sizes - use proper vaddr_t cast instead of unsigned for SEGOFSET/PGOFSET macro Tested on atari, hp300, and news68k.
1.15	28-Aug-2006	yamt	branches: 1.15.60; - remove unused bdbtofsb. - move the following macros from MD headers to sys/param.h. ctod dtoc ctob btoc dbtob btodb
1.14	11-Dec-2005	christos	branches: 1.14.4; 1.14.8; merge ktrace-lwp.
1.13	30-Oct-2003	mycroft	branches: 1.13.16; Allow a port to override MAXPHYS.
1.12	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.
1.11	26-Feb-2002	simonb	branches: 1.11.16; Purge CLSIZE, CLSIZELOG2 and MCLOFSET. Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS are defined. Remove old VM constants from cesfic port. Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).
1.10	30-May-2001	mrg	branches: 1.10.2; 1.10.8; use _KERNEL_OPT
1.9	03-May-2001	fredette	Now only define MACHINE_ARCH, _MACHINE_ARCH, and MID_MACHINE if they haven't already been defined.
1.8	30-Jun-2000	itojun	branches: 1.8.2; raise MSIZE from 128 to 256. - for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small already (less than 80) and there are chances for unwanted packet loss due to m_pullup restriction. - for other cases, the change should avoid allocating clusters in most cases (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of extension header) portmasters: if your arch chokes with the change (high memory usage or whatever), please backout the change for your arch.
1.7	12-Dec-1999	scottr	branches: 1.7.4; Add m68k_seg_offset() and m68k_page_offset() to complement m68k_trunc_seg() m68k_trunc_page(), respectively. Motivated primarily by a desire for code clarity and symmetry.
1.6	04-Dec-1999	ragge	CL* discarding.
1.5	29-Apr-1998	thorpej	branches: 1.5.14; 1.5.20; Pull in opt_gateway.h as appropriate.
1.4	20-Sep-1997	leo	Move the definition of MSGBUFSIZE up to the machine-arch level if possible. Pointed out by Bernd Ernesti.
1.3	10-Jul-1997	veego	branches: 1.3.2; Move the defines of UPAGES and NPTEPG back to the MD param.h, execpt that the sun3[x] doesn't use NPTEPG.
1.2	10-Jun-1997	veego	Add the 'Mach derived conversion macros' from <arch>/include/param.h.
1.1	10-Jun-1997	veego	New MI include file. Based on the param.h from all m68k ports.
1.3.2.1	22-Sep-1997	thorpej	Update marc-pcmcia branch from trunk.
1.5.20.2	27-Dec-1999	wrstuden	Pull up to last week's -current.
1.5.20.1	21-Dec-1999	wrstuden	Initial commit of recent changes to make DEV_BSIZE go away. Runs on i386, needs work on other arch's. Main kernel routines should be fine, but a number of the stand programs need help. cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512 byte block devices. vnd, raidframe, and lfs need work. Non 2**n block support is automatic for LKM's and conditional for kernels on "options NON_PO2_BLOCKS".
1.5.14.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.7.4.1	23-Jul-2000	itojun	pullup from main trunc (approved by releng-1-5) raise MSIZE from 128 to 256. - for sizeof(void *) == 8 arch, this is mandatory.

1.22.4.1	18-May-2020	martin	Pull up following revision(s) (requested by isaki in ticket #911): sys/dev/audio/audiodef.h: revision 1.13 sys/dev/audio/audiodef.h: revision 1.14 sys/arch/sparc/include/param.h: revision 1.74 sys/arch/evbarm/conf/GENERIC64: revision 1.148 sys/arch/sh3/include/param.h: revision 1.25 sys/arch/evbarm/conf/GENERIC: revision 1.75 sys/arch/m68k/include/param.h: revision 1.23 sys/arch/amd64/conf/GENERIC: revision 1.564 sys/arch/hppa/include/param.h: revision 1.27 sys/dev/audio/audio.c: revision 1.68 sys/arch/vax/include/param.h: revision 1.63 sys/dev/audio/audio.c: revision 1.69 Reduce default AUDIO_BLK_MS from 40msec to 10msec on all platform except m68k (m68k uses 40msec default as before). 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.

1.42	27-Dec-2023	thorpej	Stop using magic numbers for the MMU root pointer attributes and the Translation Control register, and also get rid of "#if PGSHIFT == ..." where those magic numbers are used. Instead, define new macros: MMU51_SRP_BITS, MMU51_CRP_BITS, MMU51_TCR_BITS, and MMU40_TCR_BITS, in terms of the definitions in mmu_{40,51}.h. These automagically adapt to 8K and 4K pages based on the machine-specific value of PGSHIFT.
1.41	26-Dec-2023	thorpej	Move active_pmap() and active_user_pmap() macros into pmap_motorola.c
1.40	26-Dec-2023	thorpej	- G/C the PMAP_ACTIVATE() macro, just call loadustp() directly. - In pmap_activate(), rather than checking for an idle LWP and skipping the loadustp() in that case, just check if the pmap being activate is the kernel pmap. Also, KASSERT() that the specified lwp is the current lwp.
1.39	25-Dec-2023	thorpej	loadustp(): Optimize for the overwhelmingly common case of "not the HP MMU". Rather than converting the level 1 table address to a page number before calling loadustp() only to have loadustp() convert it back to an address for the '851, '030, '040, and '060, instead pass the address and convert to a page number only in the case of the HP MMU. This is a wash on HP MMU machines (9000/320 and 9000/350), and saves at least 4 instructions (2x moveq + 2x lsXl) on every context switch on everything else.
1.38	26-Sep-2023	tsutsui	Remove trailing spaces and TABs.

1.36	14-Mar-2020	ad	pmap_remove_all(): Return a boolean value to indicate the behaviour. If true, all mappings have been removed, the pmap is totally cleared out, and UVM can then avoid doing the work to call pmap_remove() for each map entry. If false, either nothing has been done, or some helpful arch-specific voodoo has taken place.
1.35	01-Feb-2020	tsutsui	Use "__nothing" macro defined in <sys/cdefs.h> for empty pmap_update(). Suggested by pgoyette@ in PR/54869.
1.34	29-Oct-2011	tsutsui	branches: 1.34.54; 1.34.60; Use pool(9) for struct pv_entry allocations rather than uvm_km_alloc(9)/uvm_km_free(9) and ancient homegrown pv_page_info structures. Calling uvm_km_free(9) during pmap_remove(9) could cause rw_lock error in uvm_unmap1() as noted in PR port-m68k/45519. NetBSD/x68k (both real X68030 and XM6i emulator) still gets weird panic (corrupted kernel stack pointer?) on some heavy load: --- panic: MMU fault Stopped in pid 363.1 (X68k) at netbsd:cpu_Debugger+0x6: unlk a6 db> tr cpu_Debugger(4012004,8,1cbb528,2a618e0,2a5b000) + 6 db> --- but it also occurs without this change so there might be some more bugs in m68k pmap...

1.26	11-Dec-2009	tsutsui	Refactoring MD segment related definitions on m68k ports: - move macro SEGSHIFT, NBSEG, and SEGOFSET from <machine/param.h> to <m68k/pmap_motorola.h> where they should belong - also simplify NBSEG macro for both 020/030 and 040/060 cases - also move m68k_trunc_seg(), m68k_round_seg(), and m68k_seg_offset() (that use SEGOFSET) from <m68k/param.h> to <m68k/pmap_motorola.h> - add comments about each segment size value used on pmap_motorola implementation - add TIA_SIZE, TIA_SHIFT, TIB_SIZE, and TIB_SHIFT macro which can be used for ste/pte index sizes - use proper vaddr_t cast instead of unsigned for SEGOFSET/PGOFSET macro Tested on atari, hp300, and news68k.
1.25	08-Dec-2009	tsutsui	Remove unused M68K_SEG_SIZE macro. All sources use NBSEG directly. XXX: It looks NBSEG definitions in <machine/param.h> XXX: for all m68k port are incorrect, since 1997 or 2002.
1.24	06-Dec-2009	tsutsui	Move initialization of protection_codes[] and kernel_pmap() from MD pmap bootstrap sources to common pmap_bootstrap_finalize(). Tested on atari, hp300, mac68k, and news68k. XXX: Why is protection_codes[] array initialized at run time?
1.23	06-Dec-2009	tsutsui	pm_stfree in struct pmap is a bitmap value so make it unsigned.
1.22	02-Dec-2009	tsutsui	Add a common pmap_bootstrap_finalize() function which initializes lwp0 uarea, curlwp, and curpcb after MMU is turned on, using lwp0uarea variable saved during pmap_bootstrap() (or equivalent functions) for pmap_motorola based ports. Discussed with rmind@.
1.21	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	17-Jan-2009	tsutsui	Move extern decls for Sysseg, Sysptmap, Sysptsize, mem_size, virtual_avail, virtual_end, and protection_codes[] to common <m68k/pmap_motorola.h>, and also make protection_codes[] unsigned. XXX: avail_start and avail_end should also be moved, but it causes XXX: -Wshadow warnings in uvm/uvm_page.c:uvm_page_physload() and XXX: I don't have a good idea of alternative names for now.
1.19	28-Dec-2008	tsutsui	Use the global kernel_pmap_ptr pointer in each MD pmap_bootstrap.c (where MMU is not enabled yet) and make kernel_pmap_store static again. Also consistently use uintptr_t on address conversion in RELOC() macro. Tested on hp300 (PA != VA) and news68k (PA == VA).
1.18	10-Dec-2008	tsutsui	Restore kernel_pmap_store declaration since it's still used by most m68k ports in pmap_bootstrap.c.

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.

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.

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.

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.

1.12	12-Apr-2017	kamil	branches: 1.12.12; 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!
1.11	08-Apr-2017	kamil	Add new ptrace(2) API: PT_SETSTEP & PT_CLEARSTEP These operations allow to mark thread as a single-stepping one. This allows to i.a.: - single step and emit a signal (PT_SETSTEP & PT_CONTINUE) - single step and trace syscall entry and exit (PT_SETSTEP & PT_SYSCALL) The former is useful for debuggers like GDB or LLDB. The latter can be used to singlestep a usermode kernel. These examples don't limit use-cases of this interface. Define PT_*STEP only for platforms defining PT_STEP. Add new ATF tests setstep[1234]. These ptrace(2) operations first appeared in FreeBSD. Sponsored by <The NetBSD Foundation>

1.21	27-Oct-2019	rin	Expose register difinitions for _STANDALONE. Fix build failure in arch/luna68k/stand/boot.
1.20	26-Oct-2019	christos	Hide the register definitions that should eventually be removed (or prefixed with _REG_ with #ifdef _KERNEL. This avoids conflicts with let's say PC in <termcap.h>.
1.19	04-Jan-2014	dsl	branches: 1.19.30; Remove __HAVE_PROCESS_XFPREGS and add the extra parameter for the size of the fp save area to all the process_read_fpregs() and process_write_fpregs() functions. None of the functions have been modified to use the new parameters. The size is set for all the writes, but some of the arch-specific reads just pass NULL. The amd64 (and i386) need variable sized fp register save areas in order to support AVX and other enhanced register areas. These functions are rarely called - so the extra argument won't matter.

1.5	28-Apr-2008	martin	branches: 1.5.88; Remove clause 3 and 4 from TNF licenses
1.4	05-Apr-2008	tsutsui	branches: 1.4.2; 1.4.4; Use generic atomic_cas_uint() for mutex(9) and rwlock(9), and remodel old RAS based _lock_cas() implementation for m68010 into genereic atomic_cas_32().

1.5	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.28	29-Oct-2021	thorpej	Define __HAVE_STRUCT_SIGCONTEXT regardless of its current visibility.
1.27	27-Oct-2021	thorpej	Make sigcontext13 visible only to _KERNEL.
1.26	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.
1.25	27-Jan-2009	martin	Centralize fpu exception to siginfo code encoding for all m68k archs, fixes a failure in the lib/libc/ieeefp/except regression test.
1.24	19-Nov-2008	ad	Make the emulations, exec formats, coredump, NFS, and the NFS server into modules. By and large this commit: - shuffles header files and ifdefs - splits code out where necessary to be modular - adds module glue for each of the components - adds/replaces hooks for things that can be installed at runtime

1.13	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.
1.12	28-Apr-2003	bjh21	branches: 1.12.2; 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.
1.11	17-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.10	04-Jul-2002	thorpej	During signal delivery, arrange to have the signal handler invoked directly, using the trampoline only for the return path. Saves a "jsr" in the trampoline. Reviewed, tested and OK'd by Steve Woodford.
1.9	23-Jun-2002	thorpej	Swap the order of the sigcontext and hardware state in the sigframe.
1.8	30-Sep-1998	thorpej	branches: 1.8.26; 1.8.30; 1.8.38; Pull in <m68k/frame.h> if __M68K_SIGNAL_PRIVATE, for sigstate.

1.8.30.2	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.

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.

1.31	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.

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.

1.6	01-Feb-2024	andvar	s/Prototol/Protocol/ and s/Umimplemented/Unimplemented/ in comments.
1.5	19-Jan-2024	thorpej	Ensuire VECO_TO_VECI() returns an 8-bit index.
1.4	14-Jan-2024	thorpej	Provide NAUTOVECTORS and NUSERVECTORS constants.
1.3	13-Jan-2024	thorpej	Expose saved_vbr directly.
1.2	13-Jan-2024	thorpej	Provide some vector table override hooks and interfaces needed by the sun68k platforms.
1.1	13-Jan-2024	thorpej	Add a common vector table implementation for m68k platforms.
1.1	01-Feb-2020	tsutsui	branches: 1.1.2; 1.1.4; 1.1.8; 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.
