  71  * Architecture-specific ACPICA Subsystem Data Types
  72  *
  73  * The goal of these types is to provide source code portability across
  74  * 16-bit, 32-bit, and 64-bit targets.
  75  *
  76  * 1) The following types are of fixed size for all targets (16/32/64):
  77  *
  78  * u8           Logical boolean
  79  *
  80  * u8           8-bit  (1 byte) unsigned value
  81  * u16          16-bit (2 byte) unsigned value
  82  * u32          32-bit (4 byte) unsigned value
  83  * u64          64-bit (8 byte) unsigned value
  84  *
  85  * s16          16-bit (2 byte) signed value
  86  * s32          32-bit (4 byte) signed value
  87  * s64          64-bit (8 byte) signed value
  88  *
  89  * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
  90  * compiler-dependent header(s) and were introduced because there is no common
  91  * 64-bit integer type across the various compilation models, as shown in
  92  * the table below.
  93  *
  94  * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
  95  * char      8    8     8     8     8    8
  96  * short     16   16    16    16    16   16
  97  * _int32         32
  98  * int       32   64    32    32    16   16
  99  * long      64   64    32    32    32   32
 100  * long long            64    64
 101  * pointer   64   64    64    32    32   32
 102  *
 103  * Note: ILP64 and LP32 are currently not supported.
 104  *
 105  *
 106  * 2) These types represent the native word size of the target mode of the
 107  * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
 108  * usually used for memory allocation, efficient loop counters, and array
 109  * indexes. The types are similar to the size_t type in the C library and are
 110  * required because there is no C type that consistently represents the native
 111  * data width. acpi_size is needed because there is no guarantee that a
 112  * kernel-level C library is present.
 113  *
 114  * acpi_size        16/32/64-bit unsigned value
 115  * acpi_native_int  16/32/64-bit signed value
