  66. * Architecture-specific ACPICA Subsystem Data Types
  67. *
  68. * The goal of these types is to provide source code portability across
  69. * 16-bit, 32-bit, and 64-bit targets.
  70. *
  71. * 1) The following types are of fixed size for all targets (16/32/64):
  72. *
  73. * BOOLEAN Logical boolean
  74. *
  75. * UINT8 8-bit (1 byte) unsigned value
  76. * UINT16 16-bit (2 byte) unsigned value
  77. * UINT32 32-bit (4 byte) unsigned value
  78. * UINT64 64-bit (8 byte) unsigned value
  79. *
  80. * INT16 16-bit (2 byte) signed value
  81. * INT32 32-bit (4 byte) signed value
  82. * INT64 64-bit (8 byte) signed value
  83. *
  84. * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
  85. * compiler-dependent header(s) and were introduced because there is no common
  86. * 64-bit integer type across the various compilation models, as shown in
  87. * the table below.
  88. *
  89. * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
  90. * char 8 8 8 8 8 8
  91. * short 16 16 16 16 16 16
  92. * _int32 32
  93. * int 32 64 32 32 16 16
  94. * long 64 64 32 32 32 32
  95. * long long 64 64
  96. * pointer 64 64 64 32 32 32
  97. *
  98. * Note: ILP64 and LP32 are currently not supported.
  99. *
  100. *
  101. * 2) These types represent the native word size of the target mode of the
  102. * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
  103. * usually used for memory allocation, efficient loop counters, and array
  104. * indexes. The types are similar to the size_t type in the C library and are
  105. * required because there is no C type that consistently represents the native
  106. * data width. ACPI_SIZE is needed because there is no guarantee that a
  107. * kernel-level C library is present.
  108. *
  109. * ACPI_SIZE 16/32/64-bit unsigned value
  110. * ACPI_NATIVE_INT 16/32/64-bit signed value
