2008-04-18ide: remove ->hold field from ide_hwif_t (take 2)Bartlomiej Zolnierkiewicz
->hold is write-only now, remove it. v2: * v1 missed bast-ide, palm_bk3710, ide-cs and delkin_cb host drivers. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-18ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)Bartlomiej Zolnierkiewicz
hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS and given the number of bugs we can assume that there are no real users: * DMA has no chance of working because DMA resources are released by ide_unregister() and they are never allocated again. * Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls don't work for almost all hosts with "non-standard" (== non ISA-like) layout of IDE taskfile registers (there is a lot of such host drivers). * ide_port_init_devices() is not called when probing IDE devices so: - drive->autotune is never set and IDE host/devices are not programmed for the correct PIO/DMA transfer modes (=> possible data corruption) - host specific I/O 32-bit and IRQ unmasking settings are not applied (=> possible data corruption) - host specific ->port_init_devs method is not called (=> no luck with ht6560b, qd65xx and opti621 host drivers) * ->rw_disk method is not preserved (=> no HPT3xxN chipsets support). * ->serialized flag is not preserved (=> possible data corruption when using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366 (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers). * ->ack_intr method is not preserved (=> needed by ide-cris, buddha, gayle and macide host drivers). * ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it isn't initialized again (SiI3112 support needs them). * To issue an ioctl() there need to be at least one IDE device present in the system. * ->cable_detect method is not preserved + it is not called when probing IDE devices so cable detection is broken (however since DMA support is also broken it doesn't really matter ;-). * Some objects which may have already been freed in ide_unregister() are restored by ide_hwif_restore() (i.e. ->hwgroup). * ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[] slot cannot be found. * When IDE host drivers are modular unregistered port may be re-used by different host driver that owned it first causing subtle bugs. Since we now have a proper warm-plug support remove these ioctls, then remove no longer needed: - ide_register_hw() and ide_hwif_restore() functions - 'init_default' and 'restore' arguments of ide_unregister() - zeroeing of hwif->{dma,extra}_* fields in ide_unregister() As an added bonus IDE core code size shrinks by ~3kB (x86-32). v2: * fix ide_unregister() arguments in cleanup_module() (Andrew Morton). v3: * fix ide_unregister() arguments in palm_bk3710.c.

2007-10-13ide: move ide_config_drive_speed() calls to upper layers (take 2)Bartlomiej Zolnierkiewicz
* Convert {ide_hwif_t,ide_pci_device_t}->host_flag to be u16. * Add IDE_HFLAG_POST_SET_MODE host flag to indicate the need to program the host for the transfer mode after programming the device. Set it in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac and via82cxxx host drivers. * Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely skip programming of host/device for the transfer mode ("smart" hosts). Set it in it821x host driver and check it in ide_tune_dma(). * Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all direct ->set_pio_mode/->speedproc users to use these helpers. * Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc methods to callers. * Rename ->speedproc method to ->set_dma_mode, make it void and update all implementations accordingly. * Update ide_set_xfer_rate() comments. * Unexport ide_config_drive_speed(). v2: * Fix issues noticed by Sergei: - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt to setting DMA modes from sc1200_set_pio_mode() to do_special() - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma() - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode() - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode() - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL - don't set ->set_{pio,dma}_mode on it821x in "smart" mode - fix build problem in pmac.c - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c - improve patch description Changes in behavior caused by this patch: - HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change PIO mode if it821x controller is in "smart" mode - removal of two debugging printk-s (from cs5530.c and sc1200.c) - transfer modes 0x00-0x07 passed from user space may be programmed twice on the device (not really an issue since 0x00 is not supported correctly by any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid) Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-13icside: use ide_tune_dma()Bartlomiej Zolnierkiewicz
* Add "good DMA drives" hack for icside to ide-dma.c::ide_find_dma_mode() (in the long-term it should be either removed or generalized for all hosts). * Use ide_tune_dma() in icside.c::icside_dma_check(). This results in the following changes in behavior: - pre-EIDE SWDMA modes are now also respected - drive->autodma is checked instead of hwif->autodma (doesn't really matter as icside sets both to "1") * Make ide-dma.c::__ide_dma_good_drive() static and drop "__" prefix.

2007-10-11icside: fix ->speedproc to return on unsupported modes (take 5)Bartlomiej Zolnierkiewicz
* All other implementations of ->speedproc return zero on success and non-zero on failure. Currently it doesn't matter for icside host driver and isn't a bug per se since: - ide_set_xfer_rate() return value is ignored by all IDE core users - icside doesn't (yet!) use ide_tune_dma() in icside_dma_check() but sooner or later we will need to fix anyway - so lets do it now. * icside_set_speed() happily accepts unsupported transfer modes which results in drive->drive_data being set to the maximum value (480) and drive->current_speed being set to the unsupported transfer mode. Fix it. v2: * The initial version of the patch was broken because it didn't take into the account (the different from usual) return values of icside_set_speed() (Noticed by Russell). v3: * Remove no longer needed initialization/checking of cycle_time (Noticed by Sergei). * No need to set drive->drive_data if DMA is not going to be used (Noticed by Sergei). * Remove incorrect setting of drive->current_speed (Noticed by Sergei). * Move ide_config_drive_speed() at the end of icside_set_speed(). v4: * If DMA mode is not found in icside_dma_check() then just return "-1" and don't call icside_set_speed() (v3 got it wrong and "1" was returned instead). v5: * Return "-1"/"0" in icside_set_speed() instead of icside_dma_check() return value (just like it was before this patch).

2007-10-11ide: move ide_rate_filter() calls to the upper layer (take 2)Bartlomiej Zolnierkiewicz
* Move ide_rate_filter() calls from host drivers to IDE core. * Make ide_rate_filter() static. * Make 'speed' argument of ->speedproc const. v2: * Fix it8213_tune_chipset() comment.

2007-10-11ide: add missing ide_rate_filter() calls to ->speedproc()-sBartlomiej Zolnierkiewicz
* Fix icside, cris-ide, au1xxx-ide, amd74xx, via82cxxx and pmac host drivers to use ide_rate_filter(). This results in the following modes (from user requests) being clipped down: - invalid modes (values 0x46-0xFF) [ for all hosts ] - unsupported by a host UDMA modes [ for hosts which support UDMA] - all UDMA modes and MWDMA3-4 modes [ for hosts which don't support UDMA ] - invalid modes (values 0x25-0x39) [ for hosts which don't support UDMA ] * Host driver specific changes in behavior: icside: - no change cris-ide - clip unsupported UDMA3-6 modes down - fix BUG() on trying to set unsupported UDMA3-6 modes au1xxx-ide/pmac - clip unsupported UDMA modes down amd74xx/via82cxxx - clip unsupported UDMA modes down - fix random PIO timings being set for unsupported/invalid modes - fix unsupported/invalid modes being set on the device * While at it remove no longer needed checks from pmac.c driver.

Is this a bug? In original verison memset cleared sizeof(state) bytes instead of sizeof(*state). If it was intentional then this patch is invalid. If not intentional -> valid :) Please review.
