2007-05-09ACPI: created a dedicated workqueue for notify() executionAlexey Starikovskiy1-10/+35
HP nx6125/nx6325/... machines have a _GPE handler with an infinite loop sending Notify() events to different ACPI subsystems. Notify handler in ACPI driver is a C-routine, which may call ACPI interpreter again to get access to some ACPI variables (acpi_evaluate_xxx). On these HP machines such an evaluation changes state of some 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 increase in memory consumption noticed by author of the thread. Also as GPE handling is bloked, machines overheat. 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 all these horrors it's needed to not put notify events to kacpid workqueue by either executing them immediately or putting them on some other thread. It's dangerous to execute notify events in place, as it will put several ACPI interpreter stacks on top of each other (at least 4 in case of nx6125), thus causing kernel stack overflow. 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 kernel shipped with Ubuntu 6.06 LTS. Second attempt was done by me, I 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 18-rc2 as I remember. I 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 I did not received reply from Linus on a test patch sent to him. Patch went to 19-rc and was rejected with much fanfare again. There was 4th patch, which 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). Now you see last variant which adds yield() to every GPE execution. http://bugzilla.kernel.org/show_bug.cgi?id=5534 http://bugzilla.kernel.org/show_bug.cgi?id=8385 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2007-05-09Revert "ACPICA: fix AML mutex re-entrancy"Len Brown6-25/+31
This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877. These changes to AML locking were made to allow Notify handlers to be called on the stack and not deadlock. However, that scheme turns out to be flawed and was reverted by the previous commit, so this commit restores the locking to it previous design. Signed-off-by: Len Brown <len.brown@intel.com>
2007-05-09Revert "Execute AML Notify() requests on stack."Len Brown1-5/+6
This reverts commit 5f7748cf91558a5026ded5be93c5bf6c1ac34edf. While that change fixed the HP http://bugzilla.kernel.org/show_bug.cgi?id=5534 it broke the ACER: http://bugzilla.kernel.org/show_bug.cgi?id=8385 which as AML that caused Linux go recursive and stack fault.

2007-05-09Revert "md: improve partition detection in md array"Linus Torvalds4-8/+22
This reverts commit 5b479c91da90eef605f851508744bfe8269591a0. Quoth Neil Brown: "It causes an oops when auto-detecting raid arrays, and it doesn't seem easy to fix. The array may not be 'open' when do_md_run is called, so bdev->bd_disk might be NULL, so bd_set_size can oops. This whole approach of opening an md device before it has been assembled just seems to get more and more painful. I think I'm going to have to come up with something clever to provide both backward comparability with usage expectation, and sane integration into the rest of the kernel."

2007-05-09Move USB network drivers to drivers/net/usb.Jeff Garzik24-9/+10
It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.

2007-05-09sata_nv: fix ADMA freeze/thaw/irq_clear issuesRobert Hancock1-14/+78
This patch fixes some problems with ADMA-capable controllers with regard to freeze, thaw and irq_clear libata callbacks. Freeze and thaw didn't switch the ADMA-specific interrupts on or off, and more critically the irq_clear function didn't respect the restriction that the notifier clear registers for both ports have to be written at the same time even when only one port is being cleared. This could result in timeouts on one port when error handling (i.e. as a result of hotplug) occurred on the other port. As well, this fixes some issues in the interrupt handler: we shouldn't check any ADMA status if the port has ADMA switched off because of an ATAPI device, and it also checks to see if any ADMA interrupt has been raised even when we are in port-register mode.

2007-05-09sata_promise: SATAII-150/300 TX4 port numbering fixMikael Pettersson1-4/+18
There is a known problem with sata_promise on SATAII-150/300 TX4 controller cards: it enumerates drives in an order that differs from the port numbers printed on the controller cards. However, Promise's BIOS and Linux driver both get the order right. I investigated Promise's Linux driver (v1.01.0.23), and found that it explicitly changes the mapping from logical port number to ATA engine MMIO address on the SATAII TX4 cards. It does this on all SATAII TX4 cards, without inspecting revision etc. The SATAII TX2plus cards continue to use the same mapping that was used for the first-generation chips. This patch updates sata_promise to use the new port number to ATA engine mapping on SATAII TX4 cards, which fixes the drive enumeration order problem on those cards. Tested on several 1st and 2nd generation TX2plus and TX4 chips. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-05-09sata_promise: fix another error decode regressionMikael Pettersson1-1/+3
The sata_promise error decode update changed pdc_host_intr() to return and not complete the qc after detecting an error. Unfortunately not completing the qc:s causes them to always time out on error, which is wrong and has nasty side-effects. This patch updates pdc_error_intr() to call ata_port_abort(), similar to ahci and sata_sil24. Doing this is important as it makes EH see the original error and not a bogus timeout.

2007-05-09Fix hang on IBM Token Ring PCMCIA card ejectionPaul Walmsley1-5/+9
Ejecting a PCMCIA IBM Token Ring card that has not had its dev->open() called will reliably trigger an uninitialized spinlock oops when spinlock debugging is enabled. The system then hangs, occasionally softlockup oopsing. Apparently ibmtr.c:tok_interrupt() doesn't expect to be called before tok_open(), but tok_interrupt() gets called anyway when the card is ejected. So, set an already-existing flag which causes tok_interrupt() to bail out early upon card ejection. Tested by inserting and removing the PCMCIA card several times.

2007-05-09Fix a bad error case handling in read_cache_page_async()David Howells1-3/+3
Commit 6fe6900e1e5b6fa9e5c59aa5061f244fe3f467e2 introduced a nasty bug in read_cache_page_async(). It added a "mark_page_accessed(page)" at the final return path in read_cache_page_async(). But in error cases, 'page' holds the error code, and you can't mark it accessed. [ and Glauber de Oliveira Costa points out that we can use a return instead of adding more goto's ] Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
