* [PATCH] ide: fix error handling for drives which clear the FIFO on errorAlan Cox2006-06-281-1/+1
| | | | | | | | | | | | | If the controller FIFO cleared automatically on error we must not try and drain it as this will hang some chips.

* | [PATCH] ide-io: increase timeout value to allow for slave wakeupAl Boldi2006-06-261-1/+1
|/ | | | | | | | | | | | During an STR resume cycle, the ide master disk times-out when there is also a slave present (especially CD). Increasing the timeout in ide-io from 10,000 to 100,000 fixes this problem.

* [PATCH] IDE CD end-of media error fixAlan Cox2006-06-251-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch from Alan that fixes a real ide-cd.c regression causing bogus "Media Check" failures for perfectly valid Fedora install ISOs, on certain CD-ROM drives. This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the end of media problem. It may not be sufficient for some controllers (promise notably) and it does not touch the locking so the error path locking is as horked as in mainstream. From: Ingo Molnar <mingo@elte.hu> I have ported the patch to 2.6.17-rc4 and tested it by provoking end-of-media IO errors with an unaligned ISO image. Unlike the vanilla kernel, the patched kernel interpreted the error condition correctly with 512 byte granularity: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdc: Error: Illegal request -- (Sense key=0x05) Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 Buffer I/O error on device hdc, logical block 163261 Buffer I/O error on device hdc, logical block 163262 the unpatched kernel produces an incorrect error dump: hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306080 Buffer I/O error on device hdc, logical block 163260 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306088 Buffer I/O error on device hdc, logical block 163261 hdc: command error: status=0x51 { DriveReady SeekComplete Error } hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 1306096 Buffer I/O error on device hdc, logical block 163262 I do not have the right type of CD-ROM drive to reproduce the end-of-media data corruption bug myself, but this same patch in RHEL solved it.

* [PATCH] Revert ide softirq handlingJens Axboe2006-01-121-31/+3
| | | | | | | | | | | | There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len handling) where it could actually complete a request ahead of time. I suggest we just back this out for now, I will resubmit it later when I'm fully confident in it.

* [IDE] Use the block layer deferred softirq request completionJens Axboe2006-01-091-7/+35
| | | | | | | | | | This patch makes IDE use the new blk_complete_request() interface. There's still room for improvement, as __ide_end_request() really could drop the lock after getting HWGROUP->rq (why does it need to hold it in the first place? If ->rq access isn't serialized, we are screwed anyways). Signed-off-by: Jens Axboe <axboe@suse.de>
* [BLOCK] update IDE to use new blk_ordered for barriersTejun Heo2006-01-061-4/+1
| | | | | | | | | | | | | | | | | | | Update IDE to use new blk_ordered. This change makes the following behavior changes. * Partial completion of the barrier request is handled as failure of the whole ordered sequence. No more partial completion for barrier requests. * Any failure of pre or post flush request results in failure of the whole ordered sequence. So, successfully completed ordered sequence guarantees that all requests prior to the barrier made to physical medium and, then, the while barrier request made to the physical medium.

* [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo2006-01-061-3/+3
| | | | | | | | | | | | | | | | | add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

* [PATCH] ide: Workaround PM problemBenjamin Herrenschmidt2005-10-101-0/+8
| | | | | | | | | | | | | | | | | | | | | The logic in ide_do_request() doesn't guarantee that both drives will be serviced after a call. It may "forget" to service one in some circumstances, including when one of the drive is suspended (it will eventually fail to service the slave when the master is suspended for example). This prevents the wakeup requests that gets queued on wakeup from sleep from beeing serviced in some cases when 2 drives are sharing an IDE bus. The problem is deep enough in the way this code works (and there are probably a few other problematic but rare corner cases) and fixing it would require some major rethinking of the way IDE decides which channel to service. This is not 2.6.14 material. However, in the meantime, Bart has accepted this simple workaround that will fix the crash on wakeup from sleep since this specific corner case is actually hitting users to get into 2.6.14.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+1681
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
