b0e7e61135 Remove code to initialize the lid state at boot. It interfered with lid
operation for some users with pure GPE lid switches (vs. embedded
controller.)

* Serialize notifying the user in acpi_lid_notify_status_changed().  This
  way multiple lid events occur in order.
* Add an initialization pass to get the lid status at boot-time.  This
  pass does not notify any apps but gets the initial status.

d4b9ff9179 Move flags into a private ivar so it can't collide with device flags.
Unify the code to disable GPEs with the enable code.  Shutdown is handled
the same way.  ACPI now does all wake/sleep prep for child devices so
now they no longer need to call external functions in the suspend/resume
path.  Add the flags to non-ACPI busses (i.e., pci).

5fcc8a587e Use the acpi_id_probe() method instead of acpi_MatchHid(), which is now
static.

9123341378 Add support to ACPI to manage its own resources. Previously, resource
allocation was passed up to nexus.  Now, we probe sysresource objects and
manage the resources they describe in a local rman pool.  This helps
devices which attach/detach varying resources (like the _CST object) and
module loads/unloads.  The allocation/release routines now check to see if
the resource is described in a child sysresource object and if so,
allocate from the local rman.  Sysresource objects add their resources to
the pool and reserve them upon boot.  This means sysresources need to be
probed before other ACPI devices.

Changes include:
* Add ordering to the child device probe.  The current order is:  system
resource objects, embedded controllers, then everything else.
* Make acpi_MatchHid take a handle instead of a device_t arg.
* Replace acpi_{get,set}_resource with the generic equivalents.

cc85c78ce3 Update the new suspend/resume GPE methods to properly limit the GPE
based on the destination sleep state.  Add a method to restore the old
state on resume.  This is needed for the case of suspending to a very low
state disabling a GPE (i.e. S4), resuming, and then suspending to a higher
state (i.e. S3).  This case should now keep the proper GPEs enabled.

e8b4d56eb5 Restructure the wake GPE API. Now there are three functions:
acpi_wake_init:
    Evaluate _PRW and set the GPE type
acpi_wake_set_enable:
    Enable or disable a device's GPE.
acpi_wake_sleep_prep:
    Perform any last-minute changes to the device to prepare it for
    entering the given sleep state.

Also, walk the entire namespace when transitioning to a sleep state,
disabling any GPEs which aren't appropriate for the given state.  Transition
acpi_lid and acpi_button to the new API.

This clears the way for non-ACPI-aware devices to wake the system (i.e.
modems) and fixes a problem where systems power up after shutdown when a
GPE is triggered.

841caa96b4 Enable GPE at runtime rather than suspend time. This is to match the
new behavior in ACPI-CA that defers GPE configuration.  This is a temporary
measure while reworking the GPE interface.

f3fc4f8b4a Changes to implement 20040514:
* Add calls to AcpiSetGpeType.  We use wake/run as the type for lid and
button switches since wake-only causes Thinkpads to immediately wake on
the second suspend.  Note that with wake/run, some systems return both
wake and device-specific notifies so we don't register for system notifies
for lid and button switches.
* Remove the hw.acpi.osi_method tunable since it is not needed.
* Always print unknown notifies for all types.
* Add more cleanup for the EC if it fails to attach.
* Use the GPE handle now that we parse it.  This allows GPEs to be defined
in AML GPE blocks.
* Always use ACPI_NOT_ISR since it's ok to acquire a mutex in our thread
which processes queued requests.

a1fccb4765 Add device(power/sleep button and lid) wake function from sleeping state.
This is required for some Thinkpad (and maybe VAIO) machines to wake
the system up from sleep.

Currently partially implemented, more complete implementation will come later.

91467fc61d ACPI_NUMBER becomes ACPI_INTEGER. acpi_EvaluateNumber becomes
acpi_EvaluateInteger.

Use acpi_EvaluateInteger instead of doing things the hard way where
possible.

AcpiSetSystemSleepState (unofficial) becomes AcpiEnterSleepState.

Use the AcpiGbl_FADT pointer rather than searching for the FADT.

0ae554237c - 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.

15e32d5d03 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.
