146 * Architecture-specific ACPICA Subsystem Data Types
148 * The goal of these types is to provide source code portability across
149 * 16-bit, 32-bit, and 64-bit targets.
151 * 1) The following types are of fixed size for all targets (16/32/64):
153 * BOOLEAN Logical boolean
155 * UINT8 8-bit (1 byte) unsigned value
156 * UINT16 16-bit (2 byte) unsigned value
157 * UINT32 32-bit (4 byte) unsigned value
158 * UINT64 64-bit (8 byte) unsigned value
160 * INT16 16-bit (2 byte) signed value
161 * INT32 32-bit (4 byte) signed value
162 * INT64 64-bit (8 byte) signed value
164 * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
165 * compiler-dependent header(s) and were introduced because there is no common
166 * 64-bit integer type across the various compilation models, as shown in
169 * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
171 * short 16 16 16 16 16 16
173 * int 32 64 32 32 16 16
174 * long 64 64 32 32 32 32
176 * pointer 64 64 64 32 32 32
178 * Note: ILP64 and LP32 are currently not supported.
181 * 2) These types represent the native word size of the target mode of the
182 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
183 * usually used for memory allocation, efficient loop counters, and array
184 * indexes. The types are similar to the size_t type in the C library and are
185 * required because there is no C type that consistently represents the native
186 * data width. ACPI_SIZE is needed because there is no guarantee that a
187 * kernel-level C library is present.
189 * ACPI_SIZE 16/32/64-bit unsigned value
190 * ACPI_NATIVE_INT 16/32/64-bit signed value
