Description of problem: The 2.6.18 acpi implementation does not support method parameters of 'package' type. For e.g. if a device defines a _DSM method (device specific method) and that method is invoked from the driver, messages like the following are logged: ACPI Error (utcopy-0610): Packages as parameters not implemented! [20060707] Version-Release number of selected component (if applicable): 2.6.18-8.el5 How reproducible: 100% Steps to Reproduce: 1. Create/use an ACPI device that defines a _DSM method 2. Invoke the _DSM method from the driver Actual results: Messages like that above are logged. Expected results: Succesful return from the _DSM method. Additional info: Support for package parameters was added to Len Brown's ACPI -test- tree in the 20070508 ACPI-CA code drop. The code is not yet in mainline but the attached patch contains just the changes required to support package parameters. DSM argument definitions (ACPI3.0b): 9.15.1 _DSM (Device Specific Method) This optional object is a control method that enables devices to provide device specific control functions that are consumed by the device driver. Arguments: Arg0 (Buffer): UUID Arg1 (Integer): Revision ID Arg2 (Integer): Function Index Arg3 (Package): Arguments
