2007-08-01scc_pata: PIO fixesBartlomiej Zolnierkiewicz
* Use pio == 255 == "auto-tune" in scc_config_drive_for_dma() instead of forcing PIO4 on PIO fallback. Fix comment while at it. * Rename scc_tuneproc() to scc_tune_pio() and add scc_tuneproc() wrapper. Move finding of the best PIO mode and setting of transfer mode on the device to the new wrapper. * Fix scc_tune_chipset() to tune PIO modes. Do a small cleanup while at it.

2007-08-01cs5535: PIO fixesBartlomiej Zolnierkiewicz
* Fix cs5535_tuneproc() to pass PIO transfer mode value instead of PIO mode number to cs5535_set_speed() (fixes random PIO timings being programmed and a possible OOPS). Do a little cleanup while at it. * Fix cs5535_set_speed() to check if the mate device is present (fixes PIO0 taskfile timings being used if there is no other device on the cable). * Use cs5535_tuneproc() in cs5535_dma_check(). The old code had the same issue as cs5535_tuneproc() and add additionally caused 0x00-0x04 transfer mode values (== default PIO, default PIO w/ IORDY + two invalid values) being set on the device instead of values 0x08-0x0c (XFER_PIO_[0,4]).

2007-07-20ide: add support for SCSI ioctls to ide-floppyBartlomiej Zolnierkiewicz
Now that ide-floppy supports SG_IO we can add support for SCSI ioctls (except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET ones - we can add them later iff really needed). While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from generic_ide_ioctl(): - This prevents ide-{disk,tape,scsi} device drivers from obtaining REQ_TYPE_BLOCK_PC type requests which are currently unsupported by these drivers and which are potentially harmful (as reported by Andrew). - There is no functionality loss since aforementioned ioctls will now be handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl() (for devices using ide-cd driver).

This fixes PIO fallback in siimage_config_drive_for_dma() to use max PIO mode available instead of PIO4 (config_siimage_chipset_for_pio() used wrong arguments for ide_get_best_pio_mode() and as a results always tried to set PIO4). * Remove no longer needed siimage_taskfile_timing() and config_siimage_chipset_for_pio(). * Enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes from siimage_speedproc() * Bump driver version. v2: * Fix issues noticed by Sergei: - correct pair device check - trim only taskfile PIO to the slowest of the master/slave - enable ->autotune unconditionally and remove PIO tuning for UDMA/MDMA modes from siimage_speedproc() - add TODO item for IORDY bugs - minor cleanups Reviewed-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-07-19IDE: fix termination of non-fs requestsJens Axboe
ide-disk calls ide_end_request(drive, 0, 0); to finish an unknown request, but this doesn't work so well for non-fs requests, since ide_end_request() internally looks at ->hard_cur_sectors to see how much data to end. Only file system requests store a transfer value in there, pc requests fill out ->data_len as a byte based transfer value instead. Since we ask to end 0 bytes of that request, it will never be terminated and ide-disk gets stuck in a loop "handling" that same request over and over. Switch __ide_end_request() to take a byte based transfer count, and adjust ide_end_request() to look at the right field to determine how much IO to end when it's being passed in 0.

2007-07-16bsg: add a request_queue argument to scsi_cmd_ioctl()FUJITA Tomonori
bsg uses scsi_cmd_ioctl() for some SCSI/sg ioctl commands. scsi_cmd_ioctl() gets a request queue from a gendisk arguement. This prevents bsg being bound to SCSI devices that don't have a gendisk (like OSD). This adds a request_queue argument to scsi_cmd_ioctl(). The SCSI/sg ioctl commands doesn't use a gendisk so it's safe for any SCSI devices to use scsi_cmd_ioctl().

2007-07-12hd.c: remove BIOS/CMOS queriesH. Peter Anvin
An ST-506 disk these days is pretty much someone trying to pull ancient data using an auxilliary controller. Pulling data from the BIOS or CMOS is just plain wrong, since it's likely to be the primary OS disk... and would be user-entered data anyway. Instead, require the user enters it on the command line.

2007-07-11PCI: add pci_try_set_mwiRandy Dunlap
As suggested by Andrew, add pci_try_set_mwi(), which does not require return-value checking. - add pci_try_set_mwi() without __must_check - make it return 0 on success, errno if the "try" failed or error - review callers Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.
