I think this is problematic as these are nodes that have been attached to the AML tree, so if I'm not mistaken, I don't think the function should produce the expected result. I think it should look like this instead (this is not tested): ------ Status = AmlVarListAddTail ( (AML_NODE_HANDLE)ObjectNode, (AML_NODE_HANDLE)IntNode ); if (EFI_ERROR (Status)) { ASSERT (0); goto exit_handler; } IntNode = NULL; if (NewObjectNode != 0) { *NewObjectNode = ObjectNode; } goto exit_handler; error_handler: if (IntNode != NULL) { AmlDeleteTree ((AML_NODE_HANDLE)IntNode); } if (ObjectNode != NULL) { AmlDeleteTree ((AML_NODE_HANDLE)ObjectNode); } exit_handler: if (AmlNameString != NULL) { FreePool (AmlNameString); } return Status; } ------ Some 'goto exit_handler' might also need to be changed to 'goto error_handler', Otherwise, the other patches look good to me, Regards, Pierre > + > +exit_handler: > + if (AmlNameString != NULL) { > + FreePool (AmlNameString); > + } > + > + if (IntNode != NULL) { > + AmlDeleteTree ((AML_NODE_HANDLE)IntNode); > + } > + > + if (ObjectNode != NULL) { > + AmlDeleteTree ((AML_NODE_HANDLE)ObjectNode); > + } > + > + return Status; > +} > + > /** AML code generation for a method returning a NameString. > > AmlCodeGenMethodRetNameString ( > @@ -1989,6 +2113,118 @@ error_handler: > return Status; > } > > +/** AML code generation for a method returning a NameString that takes an > + integer argument. > + > + AmlCodeGenMethodRetNameStringIntegerArgument ( > + "MET0", "MET1", 1, TRUE, 3, 5, ParentNode, NewObjectNode > + ); > + is equivalent of the following ASL code: > + Method(MET0, 1, Serialized, 3) { > + Return (MET1 (5)) > + } > + > + The ASL parameters "ReturnType" and "ParameterTypes" are not asked > + in this function.
