Rewrite the acpi_battery interface to allow for other battery types
(i.e., smart battery) and fix various bugs found during the cleanup.
API changes:
* kernel access:
Access to individual batteries is now via devclass_find("battery").
Introduce new methods ACPI_BATT_GET_STATUS (for _BST-formatted data) and
ACPI_BATT_GET_INFO (for _BIF-formatted data). The helper function
acpi_battery_get_battinfo() now takes a device_t instead of a unit #
argument. If dev is NULL, this signifies all batteries.
* ioctl access:
The ACPIIO_BATT_GET_TYPE and ACPIIO_BATT_GET_BATTDESC ioctls have been
removed. Since there is now no need for a mapping between "virtual" unit
and physical unit, usermode programs can just specify the unit directly and
skip the old translation steps. In fact, acpiconf(8) was actually already
doing this and virtual unit was the same as physical unit in all cases
since there was previously only one battery type (acpi_cmbat). Additionally,
we now map the ACPIIO_BATT_GET_BIF and ACPIIO_BATT_GET_BST ioctls for all
batteries, if they provide the associated methods.
* apm compatibility device/ioctls: no change
* sysctl: no change
Since most third-party applications use the apm(4) compat interface, there
should be very few affected applications (if any).

Notify the user when the battery is critically low. In the future, we may want to shut down here but the chance of BIOS vendors getting this wrong is high. They're only supposed to announce this when all batteries hit their critical level but past experience indicates we should be conservative about this for now.

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.

MFC: FreeBSD OSPM ACPI driver. Note that this driver does not include support for PCI interrupt routing or enumeration of ISA bridges or Host to PCI bridges. While functional on some machines, this driver should be considered experimental and should be tested prior to being deployed in a production environment. Sponsored by: The Weather Channel

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.

Match namespace cleanup changes in ACPI CA 20020217 update. Use ACPI_SUCCESS/ACPI_FAILURE consistently. The AcpiGetInto* interfaces are obsoleted by ACPI_ALLOCATE_BUFFER. Kill off the timeouts that used to read _BIF and _BST. These are invoked when the battery is actually read. timeout() is dangerous in combination with ACPI, as the interpreter can block. This driver still needs more work.

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.

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.

When ensuring the destination buffer is truncated for a string obtained from a BIF, use the size of the destinatino buffer, not the length of the string to determine where to put the nul char. As a side effect, the old code would truncate the string by one character while it was possibly overflowing the buffer.
