Bug report: Kevin Oberman

MPSAFE locking

* Serialize notification of acline changes in acpi_acad_get_status().
* Remove the initializing flag. With the locking, we don't need to
push off requests for the acline before initialization is done.
* Don't check device_get_softc(), it can't return NULL.

Use ACPI_ALL_NOTIFY instead of registering handlers separately.

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

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.

Add missing <sys/module.h> includes

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.

Make unnecessary globals static and remove unused includes.

Allow the AC adapter device to be disabled with debug.acpi.disable="acad".
Even though documented, this option was never enabled even in rev 1.1.

Add MODULE_DEPEND entries so some of these drivers can eventually be

Change to acpi_{Get,Set}Integer to provide both methods. Convert all

Add devctl(4) notify support to ACPI. Various subsystems now notify
userland whenever events occur. See the example in devd.conf below
to see how to use it.

Consistently print attach messages.

Print notify values as hex.

Revert part of rev. 1.16 -- reinstate system notify handler. It turns out
at least the Casio FIVA requires this.

Requested by: takawata

Don't install a system notify handler. Move the device notify handler
installation to just before we're ready to handle events. Make a loop
more readable (no functional change).

Style cleanups to match the rest of this directory. For acpi_battery.c,
remove unused includes.

Allow non-privilaged user to retrive battery or AC line information.

Add status initialization code for acpi_cmbat and acpi_acad,
acpi_cmbat_init_battery() and acpi_cmbat_init_acline() respectively.
Call acpi_cmbat_init_battery() from acpi_cmbat_resume() too just in
case.
This is a workaround for embedded controller operations which is
unstable for about a minute (typically 30 or 40 sec.) at boot time.

Add generalized power profile code.
This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified
the events.

- move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
- call power_profile_set_state() also from APM driver when AC-line
status changes
- add call-back function for Crusoe LongRun controlling on power
profile changes for a example

Match namespace cleanup changes in ACPI CA 20020217 update.
Use ACPI_SUCCESS/ACPI_FAILURE consistently.

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.

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 :-)
