in the case where there are no interrupts routed for it does not
contain enough space to use it to route an interrupt. In the case
where we need to route an interrupt, throw away the returned buffer
and create a new one containing the interrupt we want.
boot time. Loading as a module once the system is up and running
doesn't make any sense.
- Fix acpi_FindIndexedResource (it would only check the first resource),
changes the calling interface.
- Add a new helper function (acpi_AppendBufferResource) to help building
buffers containing resources.
- Remove the beer-ware license (reqested by phk)
- Reorganise so that the PIIX4 workaround code is kept together, and
switch the workaround function via the timecounter struct, saving
a compare in the read-timecounter codepath. Also indicate that
the workaround is active by changing the timecounter hardware string.
This code is based on the mp_clock code by phk. It attempts to
detect the PIIX4 (see comments for details) and use a workaround
for its problems.
This code is experimental, and could use some testing and review by a
timekeeping enthusiast.
RSDP, it's now found via a callback).
AcpiOsSleepUsec() went away, use AcpiOsSleep() instead (we could use
AcpiOsStall() too)
AcpiFormatException() was changed to make more sense (it behaves like
our old acpi_strerror() did), so throw acpi_strerror() away (still
#defined in acpivar.h though, we need to sweep these seperately).
Monitor the system power profile, and use _SCP to adjust thermal zones
accordingly.
Simplify the behaviour of the timeout routine, and add some temporary
debugging.
PCI bus object. This should deal both with already-routed interrupts
as well as devices that need an interrupt routed.
Note that it *doesn't* deal with interlocked interrupt dependancies, nor
does it select between interrupt options in a smart way. These are
optimisations that need further work.
is a parallel adjunct to active cooling, not a lesser evil. The _ACx
levels sort from 0 being hottest, not coolest.
Sanity check the returned temperature values, since we are having
trouble reading them on some systems.
Rearrange sysctl nodes a bit; this is probably close to the final layout.
Pass the softc, not the device_t to the Notify handler.
Don't invoke the Interpreter from callout context, as it may sleep.
Use AcpiOsQueueForExecution, which is called from taskqueue_swi.
Add an ACPI subsystem mutex, and macros for handling it. Because it's
not possible to differentiate between ACPI CA acquiring mutexes for
internal use and for use by AML, and because AML in the field doesn't
handle mutexes correctly, we can't use the ACPI subsystem's internal
locking. In addition, we have other private data of our own to lock.
Add initial locking to the ACPI driver code and the thermal module.
These locks are currently inoperative.
Pull some errant style back into line.
- Reorder the acpi_* functions in a sensible fashion
- Add acpi_ForeachPackageObject and acpi_GetHandleInScope
- Use the new debugging layer/level names
- Implement most of the guts of the acpi_thermal module; passive cooling
isn't there yet, but active cooling should work.
- Implement power resource handling (acpi_powerres.c)
This compiles and mostly works, but my test coverage is small, so feedback
is welcome.
- Use __func__ instead of __FUNCTION.
- Support power-off to S3 or S5 (takawata)
- Enable ACPI debugging earlier (with a sysinit)
- Fix a deadlock in the EC code (takawata)
- Improve arithmetic and reduce the risk of spurious wakeup in
AcpiOsSleep.
- Add AcpiOsGetThreadId.
- Simplify mutex code (still disabled).
