      ACPICA: Add support for complex _PLD buffers. · be030a57
      由 Bob Moore 提交于 
      _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.

      ACPI: delete _GTS/_BFS support · 3f6f49c7
      由 Len Brown 提交于 
      _GTS and _BFS were added to the suspend/resume flow
in the ACPI 2.0 specification.

Linux dutifully implemented _GTS and _BFS.
We discovered that it was rarely seen in systems
in the field.  Further, some of those systems had
AML so bogus that it could never work -- proof that
no other operating system supports _GTS and _BFS.
So we made _GTS and _BFS optional via modparam,
and disabled them by default.

But we've had to complicate some code to keep
this support in the kernel, as these methods are defined
to be evaluated very close to sleep entry and exit.
Indeed, no other AML is ever evaluated with interrupts off.

We have submitted a proposal for _GTS and _BFS
to be officially removed from the ACPI specification
on the next revision.  Here we remove it from Linux.

      ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFS · 8a73b17e
      由 Lin Ming 提交于 
      Enhanced the sleep/wake interfaces to optionally execute the
_GTS method (Going To Sleep), and the _BFS method (Back From
Sleep).  Windows apparently does not execute these methods, and
therefore these methods are often untested. It has been seen on
some systems where the execution of these methods causes errors
and also prevents the machine from entering S5. It is therefore
suggested that host operating systems do not execute these methods
by default. In the future, perhaps these methods can be optionally
executed based on the age of the system and/or what is the newest
version of Windows that the BIOS asks for via _OSI.
