Asus laptops. It is alike to acpi_asus(4), but uses WMI interface instead
of separate ACPI device.
On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN,
Bluetooth, LCD backlight, camera, cardreader and touchpad.
On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth,
Wireless LED, control keyboard backlight brightness, monitor temperature
and fan speed. LCD brightness control doesn't work now for unknown reason,
possibly requiring some video card initialization.

Move logic of building ACPI headers for acpi_wakeup.c into better places,
remove intermediate makefile and shell script, and reduce diff between i386
and amd64.
Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the
source code location of the machine, the latter the binary output. In
general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless
we're tesitng for a specific target. The isn't even moot for
i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86,
although a specific cleanup for that likely would be needed...
It has more features than acpi_aiboost(4) and it will eventually replace
acpi_aiboost(4).

polling/interrupt-driven fallback and instead use polling only during
boot and pure interrupt-driven mode after boot. Polled mode could be
relegated completely to a legacy role if we could enable interrupts
during boot. Polled mode can be forced after boot by setting
debug.acpi.ec.polled="1", i.e. if there are timeouts.
- Use polling only during boot, shutdown, or if requested by the user.
Otherwise, use a generation count of GPEs, incremented atomically. This
prevents an old status value from being used if the EC is really slow
and the same condition (i.e. multiple IBEs for a write transaction) is
being checked.
- Check for and run the query handler directly if the SCI bit is set in
the status register during boot. Previously, the query handler wouldn't
run until interrupts were finally enabled late in boot.
- During boot and after starting a command, check if the event appears
to already have occurred before we even start waiting. If so, it's
possible the EC is very slow and we might accept an old status value.
Print a warning in this case. Once we've booted, interrupt-driven mode
should work just fine but polled mode could be unreliable. There's not
much more we can do about this until interrupts are enabled during boot.
- In the above case, we also do one final check if the interrupt-driven
mode gets a timeout. If the status is complete, it will force the
system back into polled mode since interrupt mode doesn't work. For
polled mode during boot, if the status appears to be already complete
before beginning the check loop, it waits 10 us before actually checking
the status, just in case the EC is really slow and hasn't gotten to work
on the new request yet.
- Use upper-case hex for the _Qxx method
- Use device_printf for errors, don't hide them under verbose
- Increase default total timeout to 750 ms and decrease polling interval
to 5 us.
- Don't pass the status value via the softc. Just read it directly.
- Remove the mutex. We use the sx lock for transaction serialization
with the query handler.
- Remove the Intel copyright notice as no code of theirs was ever
present in this file (verified against rev 1.1)
- Allow KTR module-only builds for ease of testing

The old message implied to me that ACPI can't be compiled in on platforms
other than amd64 and ia64. The amd64@ mailing list archive has messages
from users with the same confusion.

.if defined(KERNBUILDDIR). Thus, such fake files won't be
created at all if modules are built with the kernel.
Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.
