180 * Architecture-specific ACPICA Subsystem Data Types
182 * The goal of these types is to provide source code portability across
183 * 16-bit, 32-bit, and 64-bit targets.
185 * 1) The following types are of fixed size for all targets (16/32/64):
187 * BOOLEAN Logical boolean
189 * UINT8 8-bit (1 byte) unsigned value
190 * UINT16 16-bit (2 byte) unsigned value
191 * UINT32 32-bit (4 byte) unsigned value
192 * UINT64 64-bit (8 byte) unsigned value
194 * INT16 16-bit (2 byte) signed value
195 * INT32 32-bit (4 byte) signed value
196 * INT64 64-bit (8 byte) signed value
198 * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
199 * compiler-dependent header(s) and were introduced because there is no
200 * common 64-bit integer type across the various compilation models, as
201 * shown in the table below.
203 * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
204 * char 8 8 8 8 8 8
205 * short 16 16 16 16 16 16
206 * _int32 32
207 * int 32 64 32 32 16 16
208 * long 64 64 32 32 32 32
209 * long long 64 64
210 * pointer 64 64 64 32 32 32
212 * Note: ILP64 and LP32 are currently not supported.
215 * 2) These types represent the native word size of the target mode of the
216 * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
217 * usually used for memory allocation, efficient loop counters, and array
218 * indexes. The types are similar to the size_t type in the C library and
219 * are required because there is no C type that consistently represents the
220 * native data width. ACPI_SIZE is needed because there is no guarantee
221 * that a kernel-level C library is present.
223 * ACPI_SIZE 16/32/64-bit unsigned value
224 * ACPI_NATIVE_INT 16/32/64-bit signed value
