74 * allows the interpreter to ignore certain errors and/or bad AML constructs.

78 * 1) Allow "implicit return" of last value in a control method
79 * 2) Allow access beyond the end of an operation region
80 * 3) Allow access to uninitialized locals/args (auto-init to integer 0)
81 * 4) Allow ANY object type to be a source operand for the Store() operator
82 * 5) Allow unresolved references (invalid target name) in package objects
83 * 6) Enable warning messages for behavior that is not ACPI spec compliant
85 u8

88 * Automatically serialize ALL control methods? Default is FALSE, meaning
89 * to use the Serialized/not_serialized method flags on a per method basis.
90 * Only change this if the ASL code is poorly written and cannot handle
91 * reentrancy even though methods are marked "NotSerialized".
93 u8

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