From be030a576854238250d70135644cde6a0ba34b0d Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Fri, 17 Aug 2012 13:07:54 +0800 Subject: ACPICA: Add support for complex _PLD buffers. _PLD (Physical Location of Device) returns a bit-packed buffer that is difficult to parse. This change adds a new interface, AcpiDecodePldBuffer that parses the buffer into a more usable local struct. Also adds macros to both get and set individual fields within the packed _PLD buffer. Adds a new include file, acbuffer.h - which will be expanded to add structs for other ACPI names that return buffers. ACPICA BZ 954. Emit (in comments) the decoded contents of a static _PLD buffer in order to improve comprehension of this bit-packed buffer. Add multi-endian support to the _PLD decode routine. Deploy the multi-endian macros to extract data from the _PLD buffer.
