+ AmlCodeGenMethodRetInteger (
+ "_CBA", 0, 1, TRUE, 3, ParentNode, NewObjectNode
+ );
+ is equivalent of the following ASL code:
+ Method(_CBA, 1, Serialized, 3) {
+ Return (0)
+ }
+
+ The ASL parameters "ReturnType" and "ParameterTypes" are not asked
+ in this function. They are optional parameters in ASL.
+
+ @param [in] MethodNameString The new Method's name.
+ Must be a NULL-terminated ASL NameString
+ e.g.: "MET0", "_SB.MET0", etc.
+ The input string is copied.
+ @param [in] ReturnedInteger The value of the integer returned by the
+ method.
+ @param [in] NumArgs Number of arguments.
+ Must be 0 <= NumArgs <= 6.
+ @param [in] IsSerialized TRUE is equivalent to Serialized.
+ FALSE is equivalent to NotSerialized.
+ Default is NotSerialized in ASL spec.
+ @param [in] SyncLevel Synchronization level for the method.
+ Must be 0 <= SyncLevel <= 15.
+ Default is 0 in ASL.
+ @param [in] ParentNode If provided, set ParentNode as the parent
+ of the node created.
+ @param [out] NewObjectNode If success, contains the created node.
+
+ @retval EFI_SUCCESS Success.
+ @retval EFI_INVALID_PARAMETER Invalid parameter.
+ @retval EFI_OUT_OF_RESOURCES Failed to allocate memory.
