91 * Enable "slack mode" of the AML interpreter? Default is FALSE, and the
92 * interpreter strictly follows the ACPI specification. Setting to TRUE
93 * allows the interpreter to ignore certain errors and/or bad AML constructs.
95 * Currently, these features are enabled by this flag:
97 * 1) Allow "implicit return" of last value in a control method
98 * 2) Allow access beyond the end of an operation region
99 * 3) Allow access to uninitialized locals/args (auto-init to integer 0)
100 * 4) Allow ANY object type to be a source operand for the Store() operator
101 * 5) Allow unresolved references (invalid target name) in package objects
102 * 6) Enable warning messages for behavior that is not ACPI spec compliant
104 ACPI_INIT_GLOBAL(u8
, acpi_gbl_enable_interpreter_slack

107 * Automatically serialize all methods that create named objects? Default
108 * is TRUE, meaning that all non_serialized methods are scanned once at
109 * table load time to determine those that create named objects. Methods
110 * that create named objects are marked Serialized in order to prevent
111 * possible run-time problems if they are entered by more than one thread.
113 ACPI_INIT_GLOBAL(u8

116 * Create the predefined _OSI method in the namespace? Default is TRUE

120 ACPI_INIT_GLOBAL(u8

129 * Whether or not to validate (map) an entire table to verify

131 * allow early table validation before install it to the table manager.
132 * Note that enabling this option causes errors to happen in some OSPMs
133 * during early initialization stages. Default behavior is to allow such
136 ACPI_INIT_GLOBAL(u8

149 ACPI_INIT_GLOBAL(u8

152 * Optionally ignore an XSDT if present and use the RSDT instead.

154 * of the RSDT, the XSDT has been found to be corrupt or ill-formed on

161 * (address mismatch) between the 32-bit and 64-bit versions of the
162 * address. Although ACPICA adheres to the ACPI specification which
163 * requires the use of the corresponding 64-bit address if it is non-zero,
