 1.13 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.
 1.12 12-Jul-2018  maxv branches: 1.12.36;
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.

fenv for m68k

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.
 1.9 09-Feb-2007  ad Merge newlock2 to head.

 1.5 26-Nov-2002  lukem Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.
 1.4 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.

Initial import of the known working kernel bits for the NetBSD/cesfic
port. cesfic is a VME board with one or two mc68040 processors. See
the README file for details.
The port is working well with a.out userland, there are some problems
with ELF still, like applications running out of memory where it is not
expected. Some parts, in particular the pmap (which was taken from hp300
four years ago), need updating, but this is easier done within the NetBSD
CVS tree.

 1.2 07-May-2012  tsutsui branches: 1.2.40;
Add dummy bus_dma(9) typedefs (enabled by __HAVE_NO_BUS_DMA) in <sys/bus.h>
for ports which don't bother to have unnecessary bus_dma(9) implementation
to appease MI driver modules that require bus_dma_tag_t.

For amiga, move <m68k/bus_dma.h> inclusion from <machine/pci_machdep.h>
to <machine/bus.h> since amiga will want actual bus_dma(9) in future
for PCI devices.

Fixes builds on sys/modules/if_axe etc on ancient ports.

"Sounds good" from martin@ on port-m68k@.
 1.1 02-Jan-2011  tsutsui branches: 1.1.6; 1.1.10; 1.1.14;

 1.37 20-Jan-2024  thorpej Largely unify the <machine/cpu.h> headers on the m68k platforms.
 1.36 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).
 1.35 15-Jan-2024  thorpej Switch cesfic over to the common interrupt dispatch code.
 1.34 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.
 1.33 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().
 1.32 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!)
 1.31 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.

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>.

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.

 1.9 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@.
 1.8 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
 1.7 07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.

Initial import of the known working kernel bits for the NetBSD/cesfic
port. cesfic is a VME board with one or two mc68040 processors. See
the README file for details.
The port is working well with a.out userland, there are some problems
with ELF still, like applications running out of memory where it is not
expected. Some parts, in particular the pmap (which was taken from hp300
four years ago), need updating, but this is easier done within the NetBSD
CVS tree.

 1.2 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.

 1.8 11-Mar-2007  thorpej branches: 1.8.16; 1.8.18; 1.8.24;
- Shrink ipl_cookie_t from 32-bits to 16-bits (large enough to hold
an SR value or an IPL_* constant).
- Take advange of the smaller ipl_cookie_t to shrink kmutex_t from
16 bytes to 8 bytes by overlapping storage where possible.
- Implement a RAS-based _lock_cas() for mc68010 systems (Sun2). See
sun68k/sun68k/isr.c.

Tested on various m68k platforms, but NOT Sun2. In any case, at least
Sun2 compiles now.

sys/rwlock.h: Make this more self-contained for bool.

machine/mutex.h: Sprinkle includes so this can be used by crash(8).

ddb: New `show all tstiles' command.
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.

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.
 1.9 09-Dec-2009  tsutsui Fix wrong NBSEG values for all hp300 pmap derived m68k ports.
They were incorrect since 1997 on amiga and atari, and since 2002
on other ports, but fortunately they don't look so fatal.

Anyway, these values will be moved into <m68k/pmap_motorola.h> soon
since they are quite pmap implementation dependent.

 1.4 10-Sep-2001  chris branches: 1.4.4;
Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

is another story, but that's always been true).

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.

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.

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.

 1.19 01-Feb-2020  tsutsui branches: 1.19.30;
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.
