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 |
