4c7abcd337 Add OS layer ACPI mutex and threading support.
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

d2ab0884a6 Cleanups of verbose printing. All the messages for the debugging is
disabled unless verbose flag is set.  Also fix some messages in terms
of English.
The critical messages and error messages in probe/attach routine are
unchanged by this commit.

fb3ee113a4 Two minor changes.
- Change _ACx sysctl oid from ten of _AC[0-9] to one _ACx.
 - Better error printing on _TMP evaluation.

e9dce04d13 Some small improvements of ACPI thermal driver.
- Give a guaranteed minimum cooling run time to avoid too frequent
   cooling system On/Off switching.  The minimum cooling run time can be
   specified by hw.acpi.thermal.min_runtime in sec.
 - Refine message printing (_AC-1 -> NONE).
 - Add verbose mode enable/disable capability by hw.acpi.verbose in bool.

a19dd226fc Just print a message in acpi_tz_monitor() only when new active state
is different from the previous active state.
This reduce tons of 'acpi_tz0: _AC0: temperature 64.0 >= setpoint 64.0'
messages.

f498a8c651 Updates to match the ACPI CA 20010816 import:
- New debug macro (ACPI_DEBUG_PRINT), reducing debug-case code size.
 - New debug level/subsystem codes.

every couple of seconds is not useful.

not mandatory.

e388aaa8b0 Add support for user-requested override of cooling levels.
Monitor the system power profile, and use _SCP to adjust thermal zones
accordingly.

Simplify the behaviour of the timeout routine, and add some temporary
debugging.

31f82bbf96 Fix a couple of misunderstandings in the monitor code. Passive cooling
is a parallel adjunct to active cooling, not a lesser evil.  The _ACx
levels sort from 0 being hottest, not coolest.

Sanity check the returned temperature values, since we are having
trouble reading them on some systems.

Rearrange sysctl nodes a bit; this is probably close to the final layout.

92a1c67dda Add ACPI lock support.
Pass the softc, not the device_t to the Notify handler.

Don't invoke the Interpreter from callout context, as it may sleep.
Use AcpiOsQueueForExecution, which is called from taskqueue_swi.

fc1d6b8218 Sync to my work in progress:
- Reorder the acpi_* functions in a sensible fashion
 - Add acpi_ForeachPackageObject and acpi_GetHandleInScope
 - Use the new debugging layer/level names
 - Implement most of the guts of the acpi_thermal module; passive cooling
   isn't there yet, but active cooling should work.
 - Implement power resource handling (acpi_powerres.c)

This compiles and mostly works, but my test coverage is small, so feedback
is welcome.

7cf337a22e Tidy up.
Don't print temperatures at attach time - they're usually wrong.

Use acpi_EvaluateInteger instead of doing things the hard way.

3d96e58d42 - Convert a lot of homebrew debugging output to use the ACPI CA debugging
infrastructure.  It's not perfect, but it's a lot better than what
   we've been using so far.  The following rules apply to this:
    o BSD component names should be capitalised
    o Layer names should be taken from the non-CA set for now.  We
      may elect to add some new BSD-specific layers later.

 - Make it possible to turn off selective debugging flags or layers
   by listing them in debug.acpi.layer or debug.acpi.level prefixed
   with !.

 - Fully implement support for avoiding nodes in the ACPI namespace.
   Nodes may be listed in the debug.acpi.avoid environment variable;
   these nodes and all their children will be ignored (although still
   scanned over) by ACPI functions which scan the namespace.  Multiple
   nodes can be specified, separated by whitespace.

 - Implement support for selectively disabling ACPI subsystem components
   via the debug.acpi.disable environment variable.  The following
   components can be disabled:
    o bus	creation/scanning of the ACPI 'bus'
    o children	attachment of children to the ACPI 'bus'
    o button	the acpi_button control-method button driver
    o ec	the acpi_ec embedded-controller driver
    o isa	acpi replacement of PnP BIOS for ISA device discovery
    o lid	the control-method lid switch driver
    o pci	pci root-bus discovery
    o processor CPU power/speed management
    o thermal	system temperature detection and control
    o timer	ACPI timecounter
   Multiple components may be disabled by specifying their name(s)
   separated by whitespace.

 - Add support for ioctl registration.  ACPI subsystem components may
   register ioctl handlers with the /dev/acpi generic ioctl handler,
   allowing us to avoid the need for a multitude of /dev/acpi* control
   devices, etc.

a69e8faa90 Initial FreeBSD OSPM (operating system power management) modules for
ACPICA.  Most of these are still works in progress.  Support exists for:

 - Fixed feature and control method power, lid and sleep buttons.
 - Detection of ISA PnP devices using ACPI namespace.
 - Detection of PCI root busses using ACPI namespace.
 - CPU throttling and sleep states (incomplete)
 - Thermal monitoring and cooling control (incomplete)
 - Interface to platform embedded controllers (mostly complete)
 - ACPI timer (incomplete)
 - Simple userland control of sleep states.
 - Shutdown and poweroff.
