* alim15x3: remove redundant m5229_revision checkBartlomiej Zolnierkiewicz2007-10-131-12/+13
| | | | | | | | | | init_dma_ali15x3() guarantees that hwif->dma_base will never be set for m5229_revision < 0x20 so remove redundant m5229_revision >= 0x20 check from init_hwif_common_ali15x3(). While at it remove incorrect comment. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* sc1200: fix ->dma_base equal zero handlingBartlomiej Zolnierkiewicz2007-10-131-10/+14
| | | | | | | | | | Set hwif->atapi_dma/{ultra,mwdma}_mask and drive->autodma after checking that ->dma_base exists. If ->dma_base is not set (== PCI BAR4 cannot be reserved) then DMA hooks shouldn't be initialized or bad things will happen. OTOH hwif->set_{pio,dma}_mode hooks should be set even if hwif->dma_base == 0. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* ide: move ide_config_drive_speed() calls to upper layers (take 2)Bartlomiej Zolnierkiewicz2007-10-1335-516/+292
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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>

* icside: use ide_tune_dma()Bartlomiej Zolnierkiewicz2007-10-132-43/+17
| | | | | | | | | | | | | | | | | * 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.

While at it: * Fix pmac_ide_dma_check() return value if DMA mode is not programmed (should be "-1" otherwise ide_set_dma() will try to enable DMA). * Remove unnecessary drive->using_dma fiddling (->dma_off_quietly is always called before ide_set_dma() call and ide_set_dma() calls ->ide_dma_on if ->ide_dma_check returns "0"). v2: * No reason to blacklist all ide_floppy devices and the old code was always enabling DMA anyway (without even programming controller/device if the device was ide_floppy).

* ide-pmac: remove pmac_ide_do_setfeature() (take 2)Bartlomiej Zolnierkiewicz2007-10-133-79/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Use ide_config_drive_speed() instead of pmac_ide_do_setfeature() and remove the latter, also ide-iops.c::__ide_wait_stat() could be static again. Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's ->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than the only changes in behavior are: * if PIO mode is set then ->dma_off_queitly is called to disable DMA * if setting transfer mode fails ide_dump_status() is called to dump status v2: * IDE PMAC controllers allow separate PIO and DMA timings and PPC userland depends on this fact, and calls "hdparm -p" without calling "hdparm -d". Therefore to compensate for DMA being disabled by ide_config_drive_speed() for PIO modes: - add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver - add handling of the new flag to ide-io.c::do_special() Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | Don't check for good device status before executing the command in pmac_ide_do_setfeature() (ide_config_drive_speed() doesn't do this).

| | | | | | | | | | | | | | | | | | | * Split off checking of the status register from ide_wait_stat() to __ide_wait_stat() helper. * Use the new helper in ide_config_drive_speed(). The only change in the functionality is that the function now fails if after 20 sec (WAIT_CMD) device is still busy (BUSY_STAT bit is set) while previously instead of failing the function continued with checking for the correct device status (which would give the device additional 10 usec to clear BUSY_STAT bit). * Remove stale comment for ide_config_drive_speed(). * Remove duplicate comment for ide_wait_stat() from <linux/ide.h>.

* Driver core: change add_uevent_var to use a structKay Sievers2007-10-121-12/+5
| | | | | | | | | | | | | | | | | | This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places.

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).

Convert users of ->tuneproc to use ide_set{_max}_pio() where possible. This leaves only do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as a direct users of ->tuneproc. * Remove no longer needed ide_get_best_pio_mode() calls and printk-s reporting PIO mode selected from ->tuneproc implementations. * Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const. * Remove stale comment from ide_config_drive_speed(). v2: * Fix "ata_" prefix (Noticed by Jeff). v3: * Minor cleanups/fixups per Sergei's suggestions. v4: * Fix compile problem in drivers/ide/pci/cmd640.c (Noticed by Andrew Morton). * Improve some ->set_pio_mode comments.

Use it as an upper limit when finding the best DMA for device/host. * Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to ide_find_dma_mode(). Also add inline ide_find_dma_mode() version for CONFIG_BLK_DEV_IDEDMA=n case. * Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask() to avoid false warning from eighty_ninty_three(). * Use ide_find_dma_mode() to limit the user requested transfer mode in ide_rate_filter(). Also limit the requested mode by host max PIO mode. Above changes make ide_rate_filter() to: * Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19 and 0x25-0x39, values > 0x46 were already clipped down, same for values 0x25-0x39 but iff UDMA was not supported by the host). * Clip desired transfer mode down if it is currently unsupported by IDE core (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was not supported by the host). * Clip desired transfer mode down according to the host capabilities (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't, also ->atapi_dma flag was not respected). * Clip desired transfer mode down according to the device capabilities (except PIO modes for now which require mode work) - shouldn't be a problem since ide_set_xfer_rate() is called _after_ device has accepted given transfer mode. and also result in a number of host driver specific bugfixes: * icside - clip unsupported PIO5 mode down - fix unsupported/invalid modes being set in drive->current_speed * ide-cris - clip unsupported PIO5 and SWDMA0-2 modes down - clip DMA modes down for ATAPI devices - fix BUG() on unsupported/invalid modes * au1xxx-ide -
