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

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
