Connect macppc's power button and lid to the SUSPEND stubs

A kernel with option SUSPEND now calls gosleep() if I run zzz(8),
press the power button (when machdep.pwraction=2), or close the lid
(when machdep.lidaction=1). Because gosleep() is an empty stub, the
macppc does not really suspend; it only suspends some devices and
immediately resumes.

The interrupt from the power button or the lid needs some thread
(other than systq) to call sleep_state(). Use taskq_create(9) to
create another thread.

Add a call to device_register_wakeup(). Without this call,
sleep_state() does nothing.

ok kettenis

when the MI suspend code encounters problems, we need a way to
reset the MD state before bailing out. New MD function sleep_abort()
does that.

MI disable_lid_wakeups() is not needed, x86 systems can do this
in sleep_resume(), which seems sensible for other future systems also

add MP stubs

for non-SUSPEND kernel, put the ioctl pieces entirely inside #ifdef

the sleep_clocks() hook is not needed because the architectures which
need to do this can do it a few moments later in a different hook

Add stubs for macppc suspend

These stubs don't work; they only pretend to suspend the machine.
SUSPEND + MULTIPROCESSOR doesn't build. zzz(8) stops giving an error
message, even in no-SUSPEND kernels.

Add intr_enable in <powerpc/cpu.h>, adapted from powerpc64, because
subr_suspend.c calls intr_enable().

Return EOPNOTSUPP for unsupported ioctls

Match what apm(4/macppc) says and make apmd(8) log an approiate warning when
unsupported power actions are requested.

Merge identical cases while here.

This syncs with the apm ioctl handlers on loongson and arm64.

Refactor klist insertion and removal

Rename klist_{insert,remove}() to klist_{insert,remove}_locked().
These functions assume that the caller has locked the klist. The current
state of locking remains intact because the kernel lock is still used
with all klists.

Add new functions klist_insert() and klist_remove() that lock the klist
internally. This allows some code simplification.

APM_IOC_{SUSPEND,STANDBY}_REQ: This is to fix an issue with apm suspend
where a call to zzz suspended the machine immediately, not giving anyone
listening for apm events (other than apmd) a chance to deal with the

needs to have time to idle the 3d engine and otherwise get the device
into a recoverable state. Such things are needed until we support
modesetting in the kernel.

Now, instead of forcing a suspend, using ioctl sends out an event similar
to if you had put the lid down, giving all userland applications a

Add a two new ioctls to the apm(4) interface.

APM_IOC_{SUSPEND,STANDBY}_REQ: This is to fix an issue with apm suspend
where a call to zzz suspended the machine immediately, not giving anyone
listening for apm events (other than apmd) a chance to deal with the
upcoming change. This hit X hard since the introduction of drm, since it
needs to have time to idle the 3d engine and otherwise get the device
into a recoverable state. Such things are needed until we support
modesetting in the kernel.

Now, instead of forcing a suspend, using ioctl sends out an event similar
to if you had put the lid down, giving all userland applications a
chance to reply.

Final __P removal plus some cosmetic fixups

First round of __P removal in sys

branches: 1.2.4; 1.2.6;
Add $OpenBSD$ tags which were removed when this code was copied.

apm support for macppc. This is not fully implemented, sleep modes
and power event are not handled, however it is enough support
to poll the battery/AC/charging states of the system.
Code by Alexander Guy.

add MP stubs

for non-SUSPEND kernel, put the ioctl pieces entirely inside #ifdef

the sleep_clocks() hook is not needed because the architectures which
need to do this can do it a few moments later in a different hook

Add stubs for macppc suspend

These stubs don't work; they only pretend to suspend the machine.
SUSPEND + MULTIPROCESSOR doesn't build. zzz(8) stops giving an error
message, even in no-SUSPEND kernels.

Add intr_enable in <powerpc/cpu.h>, adapted from powerpc64, because
subr_suspend.c calls intr_enable().

Return EOPNOTSUPP for unsupported ioctls

Match what apm(4/macppc) says and make apmd(8) log an approiate warning when
unsupported power actions are requested.

Merge identical cases while here.

This syncs with the apm ioctl handlers on loongson and arm64.

Refactor klist insertion and removal

Rename klist_{insert,remove}() to klist_{insert,remove}_locked().
These functions assume that the caller has locked the klist. The current
state of locking remains intact because the kernel lock is still used
with all klists.

Add new functions klist_insert() and klist_remove() that lock the klist
internally. This allows some code simplification.

needs to have time to idle the 3d engine and otherwise get the device
into a recoverable state. Such things are needed until we support
modesetting in the kernel.

Now, instead of forcing a suspend, using ioctl sends out an event similar
to if you had put the lid down, giving all userland applications a
chance to reply.

Factorize akbd and ams drivers between mac68k and macppc; while there, start
moving out common adb code as well, and merge adb_direct.c into adb.c to
simplify external header files.

No functional change; more cleanups to come.

- merge adb_direct.h bits into adbvar.h
- rename ADB_HW_PB to ADB_HW_PMU

Final __P removal plus some cosmetic fixups

First round of __P removal in sys

branches: 1.2.4; 1.2.6;
Add $OpenBSD$ tags which were removed when this code was copied.

apm support for macppc. This is not fully implemented, sleep modes
and power event are not handled, however it is enough support
to poll the battery/AC/charging states of the system.
Code by Alexander Guy.

Harmonize battery state thresholds accross platforms.

Use the same values hardcoded in sys/dev/acpi/acpi.c where possible.

OK visa@

Various printf claim to report the PID, so actually report that and not the TID

Build testing assistance from deraadt@

kqueue attach functions should return an errno or 0, not a plain 1. Fix
the obvious cases to return EINVAL and ENXIO.

Uses generic confargs to attach the apm(4) and piic(4) drivers instead of
the specifics adb arguments.
Now apm(4) no longer depends on adb stuff and piic(4) doesn't attach on a
via-cuda machine (e.g. my color G3 iMac).

ok miod@

Add a const char* as first member of struct adb_attach_args, so that we can
pass a struct confargs * on macppc for some specific children of the adb
node, and not confuse real adb device attachments.
ok mpi@

Add a two new ioctls to the apm(4) interface.

APM_IOC_{SUSPEND,STANDBY}_REQ: This is to fix an issue with apm suspend
where a call to zzz suspended the machine immediately, not giving anyone
listening for apm events (other than apmd) a chance to deal with the
upcoming change. This hit X hard since the introduction of drm, since it
needs to have time to idle the 3d engine and otherwise get the device
into a recoverable state. Such things are needed until we support
modesetting in the kernel.
