150 * 2) Allow access beyond the end of an operation region

152 * 4) Allow ANY object type to be a source operand for the Store() operator
153 * 5) Allow unresolved references (invalid target name) in package objects
154 * 6) Enable warning messages for behavior that is not ACPI spec compliant
156 ACPI_EXTERN UINT8 ACPI_INIT_GLOBAL (AcpiGbl_EnableInterpreterSlack, FALSE);

160 * to use the Serialized/NotSerialized method flags on a per method basis.
161 * Only change this if the ASL code is poorly written and cannot handle
162 * reentrancy even though methods are marked "NotSerialized".
164 ACPI_EXTERN UINT8 ACPI_INIT_GLOBAL (AcpiGbl_AllMethodsSerialized, FALSE);
167 * Create the predefined _OSI method in the namespace? Default is TRUE
168 * because ACPI CA is fully compatible with other ACPI implementations.
169 * Changing this will revert ACPI CA (and machine ASL) to pre-OSI behavior.
171 ACPI_EXTERN UINT8 ACPI_INIT_GLOBAL (AcpiGbl_CreateOsiMethod, TRUE);

175 * RUNTIME GPEs should never be shared, and WAKE GPEs should typically only
176 * be enabled just before going to sleep.
