  65. * Architecture-specific ACPICA Subsystem Data Types
  66. *
  67. * The goal of these types is to provide source code portability across
  68. * 16-bit, 32-bit, and 64-bit targets.
  69. *
  70. * 1) The following types are of fixed size for all targets (16/32/64):
  71. *
  72. * u8 Logical boolean
  73. *
  74. * u8 8-bit (1 byte) unsigned value
  75. * u16 16-bit (2 byte) unsigned value
  76. * u32 32-bit (4 byte) unsigned value
  77. * u64 64-bit (8 byte) unsigned value
  78. *
  79. * s16 16-bit (2 byte) signed value
  80. * s32 32-bit (4 byte) signed value
  81. * s64 64-bit (8 byte) signed value
  82. *
  83. * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
  84. * compiler-dependent header(s) and were introduced because there is no common
  85. * 64-bit integer type across the various compilation models, as shown in
  86. * the table below.
  87. *
  88. * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
  89. * char 8 8 8 8 8 8
  90. * short 16 16 16 16 16 16
  91. * _int32 32
  92. * int 32 64 32 32 16 16
  93. * long 64 64 32 32 32 32
  94. * long long 64 64
  95. * pointer 64 64 64 32 32 32
  96. *
  97. * Note: ILP64 and LP32 are currently not supported.
  98. *
  99. *
  100. * 2) These types represent the native word size of the target mode of the
  101. * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
  102. * usually used for memory allocation, efficient loop counters, and array
  103. * indexes. The types are similar to the size_t type in the C library and are
  104. * required because there is no C type that consistently represents the native
  105. * data width. acpi_size is needed because there is no guarantee that a
  106. * kernel-level C library is present.
  107. *
  108. * acpi_size 16/32/64-bit unsigned value
  109. * acpi_native_int 16/32/64-bit signed value
