68 * Enable "slack" in the AML interpreter? Default is FALSE, and the
69 * interpreter strictly follows the ACPI specification. Setting to TRUE
70 * allows the interpreter to ignore certain errors and/or bad AML constructs.
72 * Currently, these features are enabled by this flag:
74 * 1) Allow "implicit return" of last value in a control method
75 * 2) Allow access beyond the end of an operation region
76 * 3) Allow access to uninitialized locals/args (auto-init to integer 0)
77 * 4) Allow ANY object type to be a source operand for the Store() operator
78 * 5) Allow unresolved references (invalid target name) in package objects
79 * 6) Enable warning messages for behavior that is not ACPI spec compliant
81 ACPI_EXTERN u8 ACPI_INIT_GLOBAL(acpi_gbl_enable_interpreter_slack, FALSE);
84 * Automatically serialize ALL control methods? Default is FALSE, meaning
85 * to use the Serialized/not_serialized method flags on a per method basis.
86 * Only change this if the ASL code is poorly written and cannot handle
87 * reentrancy even though methods are marked "NotSerialized".
89 ACPI_EXTERN u8 ACPI_INIT_GLOBAL(acpi_gbl_all_methods_serialized, FALSE);
92 * Create the predefined _OSI method in the namespace? Default is TRUE
93 * because ACPI CA is fully compatible with other ACPI implementations.
94 * Changing this will revert ACPI CA (and machine ASL) to pre-OSI behavior.
96 ACPI_EXTERN u8 ACPI_INIT_GLOBAL(acpi_gbl_create_osi_method, TRUE);
99 * Disable wakeup GPEs during runtime? Default is TRUE because WAKE and
100 * RUNTIME GPEs should never be shared, and WAKE GPEs should typically only
101 * be enabled just before going to sleep.
103 ACPI_EXTERN u8 ACPI_INIT_GLOBAL(acpi_gbl_leave_wake_gpes_disabled, TRUE);
