ece50487e9 Disable sleep requests for 5 sec after wakeup. This is needed for
some Toshiba and Thinkpad laptops.
Wakeup event is generated by power button or sleep button on some
laptops but this also generates SCI interrupt, and shutdown the system
as result.  So this is introduced so that acpi driver ignore given
requests for certain period.

931a10c9d2 Add a couple of minor changes.
- set sc->acpi_s4bios to 1 by default for hibernation until
   OS-initiated S4 transition is implemented.
 - change the behavior of acpi_sleep_state_sysctl() if new value is
   the same as old one, do nothing instead of EINVAL.

964679ce58 Fix re-enabling ACPI on wakeup from hibernation. The problem was that
acpi_Disable() cleared all GPE events.
Some old ACPI implementaions still need current re-enabling code.

e0157e3edc Two minor changes.
- Change _ACx sysctl oid from ten of _AC[0-9] to one _ACx.

b8670bed9b Remove "S4B" from sleep_state_names and add "NONE" instead.
Now you can say;
 # sysctl hw.acpi.lid_switch_state=NONE
instead of specifying unsupported _Sx object in the system.

Actually, S4B is going to disappear in ACPICA and we already have
hw.acpi.s4bios to distinguish BIOS hibernation or OS hibernation.

1611ea8727 Add S4BIOS sleep (BIOS hibernation) and DSDT overriding support.
- Add S4BIOS sleep implementation.  This will works well if MIB
   hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
   is enabled correctly).
 - Add DSDT overriding support which is submitted by takawata originally.
   If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
   acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
   ACPI CA core loads DSDT from given file rather than BIOS memory block.
   DSDT file can be generated by iasl in ports/devel/acpicatools/.
 - Add new files so that we can add our proposed additional code to Intel
   ACPI CA into these files temporary.  They will be removed when
   similar code is added into ACPI CA officially.

f9390180fe Some fix for the recent apm module changes.
- Now that apm loadable module can inform its existence to other kernel
   components  (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
 - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
 - Add simple arbitration mechanism for APM vs. ACPI.  This prevents
   the kernel enables both of them.
 - Remove obsolete `#ifdef DEV_APM' related code.
 - Add abstracted interface for Powermanagement operations.  Public apm(4)
   functions, such as apm_suspend(), should be replaced new interfaces.
   Currently only power_pm_suspend (successor of apm_suspend) is implemented.

9febbb4078 Some improvements of control method battery driver.
- Add a new MIB for battery info expire time in order to make it changeable.
   Battery info expire time can be specified by
   hw.acpi.battery.info_expire in sec.
 - Add own MALLOC type and fix some potential memory leakages.
 - Change some frequent printings to verbose printing.
 - Stop timeout during acpi_cmbat_get_bst() too.  This should reduce
   the races with BIF evaluation.
 - Remove acpi_cmbat_get_bif() invocation from acpi_cmbat_attach().
   This was redundant because this should be called from
   acpi_cmbat_timeout() now.

f86214b6b8 Add APM compatibility feature to ACPI.
This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications.  The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
 - APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
 - APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
 - APMIO_GETINFO and APMIO_GETINFO_OLD
 - APMIO_GETPWSTATUS

With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

1de1c550b1 Add locking to taskqueues. There is one mutex per task, one mutex per
queue, and a mutex to protect the global list of taskqueues.  The only
visible change is that a TASK_DESTROY() macro has been added to mirror
the TASK_INIT() macro to destroy a task before it is free'd.
