37 * Architecture-specific ACPICA Subsystem Data Types
38 *
39 * The goal of these types is to provide source code portability across
40 * 16-bit, 32-bit, and 64-bit targets.
41 *
42 * 1) The following types are of fixed size for all targets (16/32/64):
43 *
44 * u8 Logical boolean
45 *
46 * u8 8-bit (1 byte) unsigned value
47 * u16 16-bit (2 byte) unsigned value
48 * u32 32-bit (4 byte) unsigned value
49 * u64 64-bit (8 byte) unsigned value
50 *
51 * s16 16-bit (2 byte) signed value
52 * s32 32-bit (4 byte) signed value
53 * s64 64-bit (8 byte) signed value
54 *
55 * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
56 * compiler-dependent header(s) and were introduced because there is no
57 * common 64-bit integer type across the various compilation models, as
58 * shown in the table below.
59 *
60 * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
61 * char 8 8 8 8 8 8
62 * short 16 16 16 16 16 16
63 * _int32 32
64 * int 32 64 32 32 16 16
65 * long 64 64 32 32 32 32
66 * long long 64 64
67 * pointer 64 64 64 32 32 32
68 *
69 * Note: ILP64 and LP32 are currently not supported.
70 *
71 *
72 * 2) These types represent the native word size of the target mode of the
73 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
74 * usually used for memory allocation, efficient loop counters, and array
75 * indexes. The types are similar to the size_t type in the C library and
76 * are required because there is no C type that consistently represents the
77 * native data width. acpi_size is needed because there is no guarantee
78 * that a kernel-level C library is present.
79 *
80 * acpi_size 16/32/64-bit unsigned value
81 * acpi_native_int 16/32/64-bit signed value
