71 * Architecture-specific ACPICA Subsystem Data Types
72 *
73 * The goal of these types is to provide source code portability across
74 * 16-bit, 32-bit, and 64-bit targets.
75 *
76 * 1) The following types are of fixed size for all targets (16/32/64):
77 *
78 * u8 Logical boolean
79 *
80 * u8 8-bit (1 byte) unsigned value
81 * u16 16-bit (2 byte) unsigned value
82 * u32 32-bit (4 byte) unsigned value
83 * u64 64-bit (8 byte) unsigned value
84 *
85 * s16 16-bit (2 byte) signed value
86 * s32 32-bit (4 byte) signed value
87 * s64 64-bit (8 byte) signed value
88 *
89 * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
90 * compiler-dependent header(s) and were introduced because there is no common
91 * 64-bit integer type across the various compilation models, as shown in
92 * the table below.
93 *
94 * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
95 * char 8 8 8 8 8 8
96 * short 16 16 16 16 16 16
97 * _int32 32
98 * int 32 64 32 32 16 16
99 * long 64 64 32 32 32 32
100 * long long 64 64
101 * pointer 64 64 64 32 32 32
102 *
103 * Note: ILP64 and LP32 are currently not supported.
104 *
105 *
106 * 2) These types represent the native word size of the target mode of the
107 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
108 * usually used for memory allocation, efficient loop counters, and array
109 * indexes. The types are similar to the size_t type in the C library and are
110 * required because there is no C type that consistently represents the native
111 * data width. acpi_size is needed because there is no guarantee that a
112 * kernel-level C library is present.
113 *
114 * acpi_size 16/32/64-bit unsigned value
115 * acpi_native_int 16/32/64-bit signed value
