| * 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 |
