2012-07-14ACPICA: Fix possible fault in return package object repair codeBob Moore
Fixes a problem that can occur when a lone package object is wrapped with an outer package object in order to conform to the ACPI specification. Can affect these predefined names: _ALR,_MLS,_PSS,_TRT,_TSS,_PRT,_HPX,_DLM,_CSD,_PSD,_TSD https://bugzilla.kernel.org/show_bug.cgi?id=44171 This problem was introduced in 3.4-rc1 by commit 6a99b1c94d053b3420eaa4a4bc8b2883dd90a2f9 (ACPICA: Object repair code: Support to add Package wrappers) Reported-by: Vlastimil Babka <caster@gentoo.org> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Cc: <stable@vger.kernel.org> # 3.4 Signed-off-by: Len Brown <len.brown@intel.com>
2012-07-10ACPI / PM: Leave Bus Master Arbitration enabled for suspend/resumeJonathan Nieder
This is an old suspend/resume lockup fix: commit 2780cc4660e1 Author: Len Brown <len.brown@intel.com> Date: Thu Dec 23 13:43:30 2004 -0500 [ACPI] Fix suspend/resume lockup issue by leaving Bus Master Arbitration enabled. The ACPI spec mandates it be disabled only for C3. http://bugzilla.kernel.org/show_bug.cgi?id=3599 Signed-off-by: David Shaohua Li <shaohua.li@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> The bug snuck back in in commit 2feec47d4c5f (ACPICA: ACPI 5: Support for new FADT SleepStatus, SleepControl registers, 2012-02-14), presumably by copy/pasting a copy of the code without that fix for the legacy case. On affected machines, after that commit, the machine locks up hard on resume from suspend. The same fix as seven years ago still works. Addresses <https://bugzilla.kernel.org/show_bug.cgi?id=43641>.

2012-04-20Revert "ACPI: ignore FADT reset-reg-sup flag"Linus Torvalds
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.

2012-03-30ACPICA: Object repair code: Support to add Package wrappersBob Moore
Repair a common problem with objects that are defined to return a variable-length Package of sub-objects. If there is only one sub-object, some BIOS code mistakenly simply declares the single object instead of a Package with one sub-object. This function attempts to repair this error by wrapping a Package object around the original object, creating the correct and expected Package with one sub-object.

2012-03-26ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFSLin Ming
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.

2012-03-21ACPICA: Fix regression in FADT revision checksJulian Anastasov
commit 64b3db22c04586997ab4be46dd5a5b99f8a2d390 (2.6.39), "Remove use of unreliable FADT revision field" causes regression for old P4 systems because now cst_control and other fields are not reset to 0. The effect is that acpi_processor_power_init will notice cst_control != 0 and a write to CST_CNT register is performed that should not happen. As result, the system oopses after the "No _CST, giving up" message, sometimes in acpi_ns_internalize_name, sometimes in acpi_ns_get_type, usually at random places. May be during migration to CPU 1 in acpi_processor_get_throttling. Every one of these settings help to avoid this problem: - acpi=off - processor.nocst=1 - maxcpus=1 The fix is to update acpi_gbl_FADT.header.length after the original value is used to check for old revisions. https://bugzilla.kernel.org/show_bug.cgi?id=42700 https://bugzilla.redhat.com/show_bug.cgi?id=727865 Signed-off-by: Julian Anastasov <ja@ssi.bg> Acked-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
