Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot in some places, but D3cold in other places. After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD; and all references to D3hot use ACPI_STATE_D3_HOT. ACPI's _PR3 method is used to enter both D3hot and D3cold states. What distinguishes D3hot from D3cold is the presence _PR3 (Power Resources for D3hot) If these resources are all ON, then the state is D3hot. If _PR3 is not present, or all _PR0 resources for the devices are OFF, then the state is D3cold. This patch applies after Linux-3.4-rc1. A future syntax cleanup may remove ACPI_STATE_D3 to emphasize that it always means ACPI_STATE_D3_COLD. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Acked-by: Rafael J.

|
|
*
|
|
* The goal of these types is to provide source code portability across
|
|
* 16-bit, 32-bit, and 64-bit targets.
|
|
*
|
|
* 1) The following types are of fixed size for all targets (16/32/64):
|
|
*
|
|
* BOOLEAN Logical boolean
|
|
*
|
|
* UINT8 8-bit (1 byte) unsigned value
|
|
* UINT16 16-bit (2 byte) unsigned value
|
|
* UINT32 32-bit (4 byte) unsigned value
|
|
* UINT64 64-bit (8 byte) unsigned value
|
|
*
|
|
* INT16 16-bit (2 byte) signed value
|
|
* INT32 32-bit (4 byte) signed value
|
|
* INT64 64-bit (8 byte) signed value
|
|
*
|
|
* COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
|
|
* compiler-dependent header(s) and were introduced because there is no common
|
|
* 64-bit integer type across the various compilation models, as shown in
|
|
* the table below.
|
|
*
|
|
* Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
|
|
* char 8 8 8 8 8 8
|
|
* short 16 16 16 16 16 16
|
|
* _int32 32
|
|
* int 32 64 32 32 16 16
|
|
* long 64 64 32 32 32 32
|
|
* long long 64 64
|
|
* pointer 64 64 64 32 32 32
|
|
*
|
|
* Note: ILP64 and LP32 are currently not supported.
|
|
*
|
|
*
|
|
* 2) These types represent the native word size of the target mode of the
|
|
* processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
|
|
* usually used for memory allocation, efficient loop counters, and array
|
|
* indexes. The types are similar to the size_t type in the C library and are
|
|
* required because there is no C type that consistently represents the native
|
|
* data width. ACPI_SIZE is needed because there is no guarantee that a
|
|
* kernel-level C library is present.
|
|
*
|
|
* ACPI_SIZE 16/32/64-bit unsigned value
|
|
* ACPI_NATIVE_INT 16/32/64-bit signed value
