HP nx6125/nx6325/... machines have a _GPE handler with an infinite loop sending Notify() events to different ACPI subsystems. The notify handler in the ACPI thermal driver is a C-routine, which may invoke the ACPI interpreter again to get access to some ACPI variables such as temperature. (acpi_evaluate_xxx) On these HP machines such an evaluation changes state of an ASL variable and lets the loop above break. In the current ACPI implementation, Notify requests are being deferred to the same kacpid workqueue on which the above GPE handler with infinite loop is executing. Thus we have a deadlock -- loop will continue to spin, sending notify events, and at the same time preventing these notify events from being run on a workqueue. All notify events are deferred, thus we see explosion in memory consumption. Also as GPE handling is blocked, machines overheat because ACPI-based fan control is stalled. Eventually by external poll of the same acpi_evaluate, kacpid is released and all the queued notify events are free to run, thus 100% CPU utilization by kacpid for several seconds or more. To prevent this failure, Linux must not send notify events to the kacpid workqueue -- either executing them immediately or putting them on some other thread. The first attempt to create a new thread was done by Peter Wainwright He created a bunch of threads, which were stealing work from a kacpid workqueue. This patch appeared in 2.6.15-based kernel shipped with Ubuntu 6.06 LTS. Second attempt was done by Alexey Starikovskiy, who created a new thread for each Notify event. This worked OK on HP nx machines, but broke Linus' Compaq n620c, by producing threads with a speed what they stopped the machine completely. Thus this patch was reverted from 2.6.18-rc2. Alexey re-made the patch to create second workqueue just for notify events, thus hopping it will not break Linus' machine. Patch was tested on the same HP nx machines in #5534 and #7122, but this broke Linus' machine also and was reverted from 2.6.19-rc with much fanfair. The 4th patch inserted schedule_timeout(1) into deferred execution of kacpid, if we had any notify requests pending, but Linus decided that it was too complex (involved either changes to workqueue to see if it's empty or atomic inc/dec). Then a 5th attempt did a yield() to every GPE execution. Finally, this 6th generation patch simply executes the notify handler on the stack. Previous attempts to do this simple solution failed because of issues in AML mutex re-entrancy which are now fixed by the previous patch in this series. http://bugzilla.kernel.org/show_bug.cgi?id=5534 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@xxxxxxxxxxxxxxx> Signed-off-by: Len Brown <len.brown@xxxxxxxxx> commit c0d127b56937c3e72c2b1819161d2f6718eee877 Author: Alexey Starikovskiy <alexey.y.starikovskiy@xxxxxxxxxxxxxxx> Date: Thu Feb 15 16:12:23 2007 -0500 ACPICA: fix AML mutex re-entrancy ACPI AML supports "serialized" methods which are protected by an implicit mutex. The mutex is re-entrant for that AML thread to allow recursion. However, Linux implements notify() by creating a new AML thread. So for systems where notify() re-enters a serialized method, deadlock results. The fix is to use the Linux thread_id as the key to allowing re-entrancy, not the AML thread pointer. http://bugzilla.kernel.org/show_bug.cgi?id=5534 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@xxxxxxxxxxxxxxx> Signed-off-by: Len Brown <len.brown@xxxxxxxxx> commit 156c221b728ccd4657c359cd25428946856beca8 Author: Mattia Dongili <malattia@xxxxxxxx> Date: Mon Feb 12 22:01:07 2007 +0100 sony-laptop: allow complex per-value input/output validation Replace sony_acpi_value.{min,max} with a callback function that allows more complex reasoning in accepting input and presenting output.

Len notes that "Eventually we may bundle ACPI/PNP/PNPACPI..." but if/when that happens, ACPI can simplify this without my help. And until it does, the separate patch creating a platform_device (on all X86_PC systems, even without ACPI) will be needed.
