* Architecture-specific ACPICA Subsystem Data Types
|
|
*
|
|
* 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):
|
|
*
|
|
* u8 Logical boolean
|
|
*
|
|
* u8 8-bit (1 byte) unsigned value
|
|
* u16 16-bit (2 byte) unsigned value
|
|
* u32 32-bit (4 byte) unsigned value
|
|
* u64 64-bit (8 byte) unsigned value
|
|
*
|
|
* s16 16-bit (2 byte) signed value
|
|
* s32 32-bit (4 byte) signed value
|
|
* s64 64-bit (8 byte) signed value
|
|
*
|
|
* COMPILER_DEPENDENT_UINT64/s64 - 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
