From defba1d8f233c0d5cf3e1ea6aeb898eca7231860 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Fri, 16 Dec 2005 17:05:00 -0500 Subject: [ACPI] ACPICA 20051216 Implemented optional support to allow unresolved names within ASL Package objects. A null object is inserted in the package when a named reference cannot be located in the current namespace. Enabled via the interpreter slack flag which Linux has enabled by default (acpi=strict to disable slack). This should eliminate AE_NOT_FOUND exceptions seen on machines that contain such code. Implemented an optimization to the initialization sequence that can improve boot time. During ACPI device initialization, the _STA method is now run if and only if the _INI method exists. The _STA method is used to determine if the device is present; An _INI can only be run if _STA returns present, but it is a waste of time to run the _STA method if the _INI does not exist. (Prototype and assistance from Dong Wei) Implemented use of the C99 uintptr_t for the pointer casting macros if it is available in the current compiler. Otherwise, the default (void *) cast is used as before. Fixed some possible memory leaks found within the execution path of the Break, Continue, If, and CreateField operators. (Valery Podrezov) Fixed a problem introduced in the 20051202 release where an exception is generated during method execution if a control method attempts to declare another method.
