List some obvious remaining items to-do

Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and
intr_unmask().

XXX ARM and IA64 implementations of acpi_md_intr_mask() and
acpi_md_intr_unmask() are just stubs for now.

change "InterruptNumber" to "irq" to fix compilation

Add MD functions for establishing and disestablishing interrupt handlers.

branches: 1.7.2;
Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing
the xname. I extend the API with AcpiOsInstallInterruptHandler_xname()
for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".

Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.

Follow IA-64 with the x86-specific ACPI MD functions and move these where
they belong to. Remove an unused function. Minor KNF. No functional change.

Move the evaluation of the _PDC control method out from the acpicpu(4)
driver to the main acpi(4) stack. Follow Linux and evaluate it early.
Should fix PR port-amd64/42895, possibly also PR kern/42583, and many
other comparable bugs.

A common sense explanation is that Intel supplies additional CPU tables to
OEMs. BIOS writers do not bother to modify their DSDTs, but instead load
these extra tables dynamically as secondary SSDT tables. The actual Load()
happens when the _PDC method is invoked, and thus namespace errors occur
when the CPU-specific ACPI methods are not yet present but referenced in the
AML by various drivers, including, but not limited to, acpitz(4).

branches: 1.3.6;
Move the function that counts the CPUs from acpicpu(4) to the MD layer.

Move ACPI_FLUSH_CPU_CACHE() (a.k.a. WBINVD on x86) to MD headers where it
belongs to. Let IA-64 define its own function/instruction instead of
requiring a dummy wbinvd() to satisfy the definition in a MI header.

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

branches: 1.19.8;
mark nsmb major obsolete

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

branches: 1.17.6;
Systematize handling of removed drivers.

- Every driver that was removed and whose number hasn't already been
reused is now listed with a commented-out "obsolete" line.
- The format of these has been systematized. Future format changes can
probably be safely done with a script.
- This does not include a few cases of assignments that only lasted a
couple days, or stuff from before major reorgs. Some of these may
be included nonetheless, because there was a lot of ground to cover
and therefore not a lot of time to dig into history in detail.

Note that the obsolete listings do not mean the major numbers can
never be reused; that's up to portmasters and/or core. It does mean
that they won't be reused by accident, however, which in some cases
(depending on the driver, how widely used it was, its family of device
nodes, their default permissions, etc.) can be quite dangerous.

Note that some of the things now explicitly listed as obsolete are
really ancient history. My scan went back as far as when the majors
files were added. (But not before that.)

Restore satlink's majors entries commented out and marked obsolete.
Otherwise they might accidentally get reused later and cause a
security problem.

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

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.

Don't check for unsigned variables being less than 0 in

It would probably be better to change the call signature so the

really know exactly what this code is trying to do I'm not comfortable
changing it.

Do this for all architectures, even if the trapframe is fully

correct, and most likely (with the exception of sh3 which has an
intermediate call to ufetch_int in the middle) the compiler can
eliminate redundant stores in these routines.

madt.c & mainbus.c: fix build with acpica 20221020

AcpiTbChecksum() was renamed AcpiUtChecksum() during code consolidation.

Merge thorpej-cfargs2.

branches: 1.12.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional

pa_flags) without changing name. Correct that.

Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and
PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names
consistent with the other PCI flags and poisoning 3rd-party driver
sources that use the flags in the old bad way.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

sys: Use membar_release/acquire around reference drop.

This just goes through my recent reference count membar audit and
changes membar_exit to membar_release and membar_enter to
membar_acquire -- this should make everything cheaper on most CPUs
without hurting correctness, because membar_acquire is generally
cheaper than membar_enter.

sys: Membar audit around reference count releases.

If two threads are using an object that is freed when the reference
count goes to zero, we need to ensure that all memory operations
related to the object happen before freeing the object.

Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one
thread takes responsibility for freeing, but it's not enough to
ensure that the other thread's memory operations happen before the
freeing.

Consider:

Thread A Thread B
obj->foo = 42; obj->baz = 73;
mumble(&obj->bar); grumble(&obj->quux);
/* membar_exit(); */ /* membar_exit(); */
atomic_dec -- not last atomic_dec -- last
/* membar_enter(); */
KASSERT(invariant(obj->foo,
obj->bar));
free_stuff(obj);

The memory barriers ensure that

obj->foo = 42;
mumble(&obj->bar);

in thread A happens before

KASSERT(invariant(obj->foo, obj->bar));
free_stuff(obj);

in thread B. Without them, this ordering is not guaranteed.

So in general it is necessary to do

membar_exit();
if (atomic_dec_uint_nv(&obj->refcnt) != 0)
return;
membar_enter();

to release a reference, for the `last one out hit the lights' style
of reference counting. (This is in contrast to the style where one
thread blocks new references and then waits under a lock for existing
ones to drain with a condvar -- no membar needed thanks to mutex(9).)

I searched for atomic_dec to find all these. Obviously we ought to
have a better abstraction for this because there's so much copypasta.
This is a stop-gap measure to fix actual bugs until we have that. It
would be nice if an abstraction could gracefully handle the different
styles of reference counting in use -- some years ago I drafted an
API for this, but making it cover everything got a little out of hand
(particularly with struct vnode::v_usecount) and I ended up setting
it aside to work on psref/localcount instead for better scalability.

I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I
only put it on things that look performance-critical on 5sec review.
We should really adopt membar_enter_preatomic/membar_exit_postatomic
or something (except they are applicable only to atomic r/m/w, not to
atomic_load/store_*, making the naming annoying) and get rid of all
the ifdefs.

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.

From scole_mail:
So here is a patch to get basic ski console output working. The ski
simulator was decoding the wrong registers in ssccnputc() due to
automagically inlined ssc() which contains a "break" simulated system
call.

The ski loader "skiload" has almost exactly the same inline assembly
call for ssc(), but for whatever reason, (maybe ssc() and
ski_cons_putchar() are in different files?), the ssc() function didn't
get inlined and I/O worked fine.

Make copystr() a MI C function, part of libkern and shared on all
architectures.

Notes:

- On alpha and ia64 the function is kept but gets renamed locally to avoid
symbol collision. This is because on these two arches, I am not sure
whether the ASM callers do not rely on fixed registers, so I prefer to
keep the ASM body for now.
- On Vax, only the symbol is removed, because the body is used from other
functions.
- On RISC-V, this change fixes a bug: copystr() was just a wrapper around
strlcpy(), but strlcpy() makes the operation less safe (strlen on the
source beyond its size).
- The kASan, kCSan and kMSan wrappers are removed, because now that
copystr() is in C, the compiler transformations are applied to it,
without the need for manual wrappers.

Could test on amd64 only, but should be fine.

Remove some unused assembly and other variables to reduce compile warnings

implemented consistently across all platforms. The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

correct enough as there are more entry points to forking code. Instead of
making it too good, just settle with plain SYS_fork for all ports.

Rework the fork(2)/vfork(2) event signalling under ptrace(2)

Remove the constraint of SIGTRAP event being maskable by a tracee.

Now all SIGTRAP TRAP_CHLD events are delivered to debugger.

This code touches MD specific logic and the child_return routine.
It's an intermediate step with a room for refactoring in future and
right now the least invasive approach. This allows to assert expected
behavior in already existing ATF tests and make the code prettier
in future keeping the same semantics. Probably there is a need for a MI
wrapper of child_return for shared functionality between ports.

- When forking, use own register stack for each thread
- For UAREA, arrange layout same as FreeBSD for now to hopefully
ease porting woes. add some related macros
locore.S is incorrectly assuming same layout and seems painful
to change bspstore in startup
- use ia64_init_return same as FreeBSD
- change some "printf" to "panic" for incompleted items

Arrange to update cached LWP credentials in userret() rather than during

This wasn't possible in the 3.99.x timeframe when l->l_cred came about

a remote CPU into the kernel (which is just about the only new thing in
this scheme).

Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and
intr_unmask().

acpi_md_intr_unmask() are just stubs for now.

Add MD functions for establishing and disestablishing interrupt handlers.

Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing
the xname. I extend the API with AcpiOsInstallInterruptHandler_xname()
for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".

Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.

Follow IA-64 with the x86-specific ACPI MD functions and move these where

Move the evaluation of the _PDC control method out from the acpicpu(4)
driver to the main acpi(4) stack. Follow Linux and evaluate it early.
Should fix PR port-amd64/42895, possibly also PR kern/42583, and many
other comparable bugs.

A common sense explanation is that Intel supplies additional CPU tables to
OEMs. BIOS writers do not bother to modify their DSDTs, but instead load
these extra tables dynamically as secondary SSDT tables. The actual Load()
happens when the _PDC method is invoked, and thus namespace errors occur
when the CPU-specific ACPI methods are not yet present but referenced in the
AML by various drivers, including, but not limited to, acpitz(4).

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.
