ACPI: Enable bit 11 in _PDC to advertise hw coord

2009-02-12T17:30:59+00:00

commit d96f94c604453f87fe24154b87e1e9a3a72511f8 upstream.

Bit 11 in intel PDC definitions is meant for OS capability to handle
hardware coordination of P-states. In Linux we have always supported
hwardware coordination of P-states. Just let the BIOSes know that we
support it, by setting this bit.

Some BIOSes use this bit to choose between hardware or software coordination
and without this change below, BIOSes switch to software coordination, which
is not very optimal in terms of power consumption and extra wakeups from idle.

ACPICA: Fix wrong resource descriptor length for 64-bit build

2009-02-06T22:00:43+00:00

commit 9db4fcd99f7ef886ded97cd26a8642c70fbe34df upstream.

The "minimal" descriptors such as EndTag are calculated as 12
bytes long, but the actual length in the internal descriptor is
16 because of the round-up to 8 on 64-bit build.

ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernels

2009-02-06T22:00:42+00:00

commit 27663c5855b10af9ec67bc7dfba001426ba21222 upstream

As of version 2.0, ACPI can return 64-bit integers.  The current
acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.

lenb: replaced use of "acpi_integer" with "unsigned long long"
lenb: fixed bug in acpi_thermal_trips_update()

ACPICA: Additional error checking for pathname utilities

2008-08-15T00:12:16+00:00

Add error check after all calls to acpi_ns_get_pathname_length.
Add status return from acpi_ns_build_external_path and check after
all calls.  Add parameter validation to acpi_ut_initialize_buffer.

PCI: disable ASPM per ACPI FADT setting

2008-07-28T21:56:09+00:00

The ACPI FADT table includes an ASPM control bit. If the bit is set, do
not enable ASPM since it may indicate that the platform doesn't actually
support the feature.

ACPI: Enhance /sys/firmware/interrupts to allow enable/disable/clear from user-space

2008-07-16T21:27:04+00:00

Allow users to enable/disable/clear a specific & valid GPE/Fixed Event
in user space.

This is useful for debugging, especially for some
interrupt storm issues.

All wakeup GPEs are disabled and they can not be enabled at runtime,
and we mark them as invalid.

All GPEs that don't have a _Lxx/_Exx method are marked as invalid.

All Fixed Events that don't have an event handler are marked as invalid
and they can't be enabled until an event handler is registered.
