ACPI / ACPICA: Avoid writing full enable masks to GPE registers

2010-08-02T17:30:20+00:00

commit c9a8bbb7704cbf515c0fc68970abbe4e91d68521 upstream.

ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after
an event signaled by it has been handled.  However, this function
writes the entire GPE enable mask to the GPE's enable register which
may not be correct.  Namely, if one of the other GPEs in the same
register was previously enabled by acpi_enable_gpe() and subsequently
disabled using acpi_set_gpe(), acpi_hw_write_gpe_enable_reg() will
re-enable it along with the target GPE.

To fix this issue rework acpi_hw_write_gpe_enable_reg() so that it
calls acpi_hw_low_set_gpe() with a special action value,
ACPI_GPE_COND_ENABLE, that will make it only enable the GPE if the
corresponding bit in its register's enable_for_run mask is set.

ACPI: Use GPE reference counting to support shared GPEs

2010-02-23T00:20:45+00:00

ACPI GPEs may map to multiple devices.  The current GPE interface
only provides a mechanism for enabling and disabling GPEs, making
it difficult to change the state of GPEs at runtime without extensive
cooperation between devices.

Add an API to allow devices to indicate whether or not they want
their device's GPE to be enabled for both runtime and wakeup events.

Remove the old GPE type handling entirely, which gets rid of various
quirks, like the implicit disabling with GPE type setting. This
requires a small amount of rework in order to ensure that non-wake
GPEs are enabled by default to preserve existing behaviour.

Based on patches from Matthew Garrett .

ACPICA: Remove unused uint32_struct type

2010-01-22T17:30:08+00:00

This type is not used in ACPICA and thus removed.

ACPICA: Remove obsolete ACPI_INTEGER (acpi_integer) type

2010-01-22T17:30:06+00:00

This type was introduced as the code was migrated from ACPI 1.0
(with 32-bit AML integers) to ACPI 2.0 (with 64-bit integers). It
is now obsolete and this change removes it from the ACPICA code
base, replaced by u64.  The original typedef has been retained
for now for compatibility with existing device driver code.
