Description Bryn M. Reeves 2007-05-31 15:20:48 UTC
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):

How reproducible:

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.
          Arg0 (Buffer):             UUID
          Arg1 (Integer):            Revision ID
          Arg2 (Integer):            Function Index
          Arg3 (Package):            Arguments

Comment 3 Peter Martuccelli 2007-06-20 14:40:12 UTC
Code is upstream as of .22, no devel ACK for R5.1.  Feature will be
considered/targeted for inclusion in R5.2.

Comment 6 Brian Maly 2007-06-25 20:00:24 UTC
How is this hardware affected by this issue? Is it just error messages in the
log? Or is the hardware non-functional in some way? Please provide a detailed
description on the extent of this problem.
