acpibat: look for _BIX first before falling back on _BIF

ACPI 4.0 deprecated _BIF for battery status so some newer machines
are exporting _BIX which extends _BIF's package with a few extra
fields. When using _BIX, export the new discharge cycle count as a
sensor.

ok deraadt

add acpisbs, an acpi smart battery subsystem driver reading data
over smbus

currently disabled because it conflicts with acpibat

ok deraadt, kettenis

Deduplicate the CRS parsing code and handle broken ACPI implementations.

This change was prompted by a report from Ilya Kaliman where acpiec(4)
failed to initialize on his Acer Aspire S7.

Further investigations showed that the machine had 4 instead of 2 resources
defined inside the EC device which is a violation of all existing ACPI
revisions.


We now handle such machines by using the aml resource parser directly, which
lead to the removal of the existing one from acpiec.c, and ignoring extra
resources (although they are reported in the dmesg).

In the process I also done a couple of more style(9) fixes.

If a machine has no _LIDs, then none can be open. This diff fixes a problem
where machines without any _LIDs were going back to sleep after hibernate
due to the recent suspend-if-lid-closed-on-resume diff. Noticed on qemu,
which doesn't have any _LIDs.

discussed with deraadt

If resuming from sleep (zzz/ZZZ) and the lid is still closed, go back to
sleep. This prevents accidental lid flex or slight opening in a backpack
from waking the machine up and leaving it resumed (powered on).

Expose bif_capacity as the 'design capacity' through an acpibat sensor,
giving you the original capacity of the battery:

hw.sensors.acpibat0.watthour0=64.07 Wh (last full capacity)
hw.sensors.acpibat0.watthour4=84.24 Wh (design capacity)

hw.sensors.acpibat0.amphour0=2.03 Ah (last full capacity)
hw.sensors.acpibat0.amphour4=4.40 Ah (design capacity)

Make the ACPI EC aware of the AML global lock.

Okay deraadt@, kettenis@.

Always call _PSW on _LID devices that support it to enable lid open to
resume the machine. Conversely disable it when the machine wakes up.

Make powernow-k8 on amd64 and i386 use the _PSS object from acpi to
retreive p_state data as spelled out in the amd64 bios and kernel
developers guide. This code is still a little rough around the edges but
has been tested by myself on a tyan machine and by phessler at theapt
dot org on an HP DL145. This diff also takes a first stab and cleaning up
the acpicpu dmesg spam.

ok tedu, marco

In acpidock_softc, change sc_sens from being a one element long array to
simply being a single struct ksensor.

Whitespace cleanup.

Add a TAILQ, aml_nodelist, of devices depending on the dock device to
struct acpidock_softc and stuff devices into it during attach.

This list is not yet used, but I have code ready to handle the ACPI side
of this. However, it still doesn't handle that there may in fact be
multiple dock devices in a machine (e.g. on pre-60 series ThinkPads), but
I need to figure out how to do so properly first. In the mean time I want
this in the tree so I don't lose the code.

split userland & kernel struct sensor/sensordev so that the addition
of new fields in the future is less disruptive. This is done similar
to how struct proc is handled for ps(1). ok jmc (man page changes)
tested fkr simon, and more suggestions from millert

Add some more _STA flags.

Actually add the acpidock indicator sensor stuff to the softc struct so
acpidock compiles. I had this in my tree and forgot to commit with the
acpidock.c change yesterday. :(

Reported by Johan Mson Lindman.

Remove comment that I committed by accident.

Add driver for ACPI docking stations.

Not completely functional yet, e.g. undocking doesn't work yet but put
it in the tree to be able to safely work on this.

Check whether PCI interrupt link devices are enabled.
Based on a diff from marco@.

Oops forgot this bit as part of the cleanup for acpiac. From Constantine
Murinen.

Add polling to devices that require it such as acpibat and acpitz.
Use the same tsleep/wakeup mechanism as the interrupt code to keep it non-
concurrent.

adapt to new two-level sensor api; Constantine A. Murenin

more minor knf

After a long debate at the hackathon it was decided that the acpi implementation
is not concurrent if the sensors thread goes away. This makes acpi completly
lockless.

Replace ACPI ioctls with APM ioctls. This makes ACPI talk the same protocol
as APM therefore userspace can now retrieve power information in the same
fashion as all other apm arches (zaurus, macppc, i386 etc).
