73 * Architecture-specific ACPICA Subsystem Data Types
74 *
75 * The goal of these types is to provide source code portability across
76 * 16-bit, 32-bit, and 64-bit targets.
77 *
78 * 1) The following types are of fixed size for all targets (16/32/64):
79 *
80 * BOOLEAN      Logical boolean
81 *
82 * UINT8        8-bit  (1 byte) unsigned value
83 * UINT16       16-bit (2 byte) unsigned value
84 * UINT32       32-bit (4 byte) unsigned value
85 * UINT64       64-bit (8 byte) unsigned value
86 *
87 * INT16        16-bit (2 byte) signed value
88 * INT32        32-bit (4 byte) signed value
89 * INT64        64-bit (8 byte) signed value
90 *
91 * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
92 * compiler-dependent header(s) and were introduced because there is no common
93 * 64-bit integer type across the various compilation models, as shown in
94 * the table below.
95 *
96 * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
97 * char      8    8     8     8     8    8
98 * short     16   16    16    16    16   16
99 * _int32         32
100 * int       32   64    32    32    16   16
101 * long      64   64    32    32    32   32
102 * long long            64    64
103 * pointer   64   64    64    32    32   32
104 *
105 * Note: ILP64 and LP32 are currently not supported.
106 *
107 *
108 * 2) These types represent the native word size of the target mode of the
109 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
110 * usually used for memory allocation, efficient loop counters, and array
111 * indexes. The types are similar to the size_t type in the C library and are
112 * required because there is no C type that consistently represents the native
113 * data width. ACPI_SIZE is needed because there is no guarantee that a
114 * kernel-level C library is present.
115 *
116 * ACPI_SIZE        16/32/64-bit unsigned value
117 * ACPI_NATIVE_INT  16/32/64-bit signed value
