* [PATCH] IDE CD end-of media error fixAlan Cox2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] Fix cdrom being confused on using kdumpRachita Kothiyal2006-06-23
| | | | | | | | | | | | | | | | | | I have seen the cdrom drive appearing confused on using kdump on certain x86_64 systems. During the booting up of the second kernel, the following message would keep flooding the console, and the booting would not proceed any further. hda: cdrom_pc_intr: The drive appears confused (ireason = 0x01) In this patch, whenever we are hitting a confused state in the interrupt handler with the DRQ set, we end the request and return ide_stopped. Using this I dont see the status error.

* [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo2006-01-06
| | | | | | | | | | | | | | | | | 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: MODALIAS support for autoloading of ide-cd, ide-disk, ...Kay Sievers2006-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ... Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and ide-tape, to autoload these modules depending on the probed media type of the IDE device. It is used by udev and replaces the former agent shell script of the hotplug package, which was required to lookup the media type in the proc filesystem. Using proc was racy, cause the media file is created after the hotplug event is sent out. The module autoloading does not take any effect, until something like the following udev rule is configured: SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}" The module ide-scsi will not be autoloaded, cause it requires manual configuration. It can't be, and never was supported for automatic setup in the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported media types, would just lead to a default blacklist entry anyway. $ modinfo ide-disk filename: /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko description: ATA DISK Driver alias: ide:*m-disk* license: GPL ... $ modprobe -vn ide:m-disk insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko $ cat /sys/bus/ide/devices/0.0/modalias ide:m-disk It also adds attributes to the IDE device: $ tree /sys/bus/ide/devices/0.0/ /sys/bus/ide/devices/0.0/ |-- bus -> ../../../../../../../bus/ide |-- drivename |-- media |-- modalias |-- power | |-- state | `-- wakeup `-- uevent $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media} ide:m-disk hda disk Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] IDE CD reports current speedEric Piel2005-06-23
| | | | | | | | | | | | | | | | | | | | The current ide-cd driver reports the CDROM speed (as found in /proc/sys/dev/cdrom/info) as the current speed when loading the driver. Changing the speed of the cdrom drive (by "eject -x" for instance) doesn't update the speed reported by the kernel. Updating the info could be valuable for the user as it's the only way to know if the drive accepted the request or discarded it. It could even be used to list all the available speeds of the drive. The attached patch modifies the ide-cd driver so that after every speed change request the new speed is updated. Please note that the actual modification is very little but I had to touch quite a few lines in order to avoid to pre-declare the sub-functions.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
