A warning is only displayed in debug mode or when the interpreter is in "strict" mode, since some working machines do in fact contain invalid ACPI names.

2012-09-21ACPICA: Add support for complex _PLD buffers.Bob Moore3-12/+126
_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.

2012-07-31ACPI: delete _GTS/_BFS supportLen Brown4-51/+22
_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. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Ingo Molnar <mingo@kernel.org> Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

This reverts commit cf450136bfde77c7f95065c91bffded4aa7fa731. It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte: "On reboot it shuts down as normal. The last lines displayed are: >Unmounting temporary filesystems.. [OK] >Deactivating swap... [OK] >Unmounting local filesystems... [OK] >Will now restart > Restarting system Then I hear it accessing the cd-drive, but then it's being stuck." Jörg bisected the regression to this commit. That commit fixes another machine (see https://bugzilla.kernel.org/show_bug.cgi?id=11533 for details) that has a BIOS bug and doesn't support ACPI reset. However, at least one of those other reporters no longer even has the machine in question, and had a different workaround to begin with. Besides, it clearly was a buggy BIOS. Let's not break the correct case to fix that case.

2012-03-27ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFSLin Ming4-33/+56
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.
