2008-02-06ide: remove ide_setup_ports()Bartlomiej Zolnierkiewicz
ide-cris.c: * Add cris_setup_ports() helper and use it instead of ide_setup_ports() (fixes random value being set in ->io_ports[IDE_IRQ_OFFSET]). buddha.c: * Add buddha_setup_ports() helper and use it instead of ide_setup_ports(). falconide.c: * Add falconide_setup_ports() helper and use it instead of ide_setup_ports(), also fix return value of falconide_init() while at it. gayle.c: * Add gayle_setup_ports() helper and use it instead of ide_setup_ports(). macide.c: * Add macide_setup_ports() helper and use it instead of ide_setup_ports() (fixes incorrect value being set in ->io_ports[IDE_IRQ_OFFSET]). q40ide.c: * Fix q40_ide_setup_ports() comments. ide.c: * Remove no longer needed ide_setup_ports().

2008-02-02ide: remove ->nice0 and ->nice2 fields from ide_drive_tBartlomiej Zolnierkiewicz
* ->nice0 and ->nice2 ide_drive_t fields are always zero so remove them. * IDE_NICE_0 and IDE_NICE_2 defines from <linux/hdreg.h> are no longer used by any kernel code so cover them with #ifndef/#endif __KERNEL__.

2008-02-02ide: add ide_deprecated_find_port() helperBartlomiej Zolnierkiewicz
* Factor out code for finding ide_hwifs[] slot from ide_register_hw() to ide_deprecated_find_port(). * Convert bast-ide, ide-cs and delkin_cb host drivers to use ide_device_add() instead of ide_register_hw() (while at it drop doing "ide_unregister()" loop which tries to unregister _all_ IDE interfaces if useable ide_hwifs[] slot cannot be find). This patch leaves us with only two ide_register_hw() users: - drivers/macintosh/mediabay.c - drivers/ide/ide.c Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide: add 'init_default' and 'restore' arguments to ide_unregister()Bartlomiej Zolnierkiewicz
* Add 'init_default' (flag for calling init_hwif_default()) and 'restore' (flag for calling ide_hwif_restore()) arguments to ide_unregister(). * Update ide_unregister() users to set 'init_default' and 'restore' flags. * No need to set 'init_default' flag in ide_register_hw() if the setup done by init_hwif_default() is going to be overridden by ide_init_port_hw(). * No need to set 'init_default' and 'restore' flags in cleanup_module(). There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide: add struct ide_port_info instances to legacy host driversBartlomiej Zolnierkiewicz
* Remove 'struct pci_dev *dev' argument from ide_hwif_setup_dma(). * Un-static ide_hwif_setup_dma() and add CONFIG_BLK_DEV_IDEDMA_PCI=n version. * Add 'const struct ide_port_info *d' argument to ide_device_add[_all](). * Factor out generic ports init from ide_pci_setup_ports() to ide_init_port(), move it to ide-probe.c and call it in in ide_device_add_all() instead of ide_pci_setup_ports(). * Move ->mate setup to ide_device_add_all() from ide_port_init(). * Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable ->autotune currently. * Setup hwif->chipset in ide_init_port() but iff pi->chipset is set (to not override setup done by ide_hwif_configure()). * Add ETRAX host handling to ide_device_add_all(). * cmd640.c: set IDE_HFLAG_ABUSE_* also for CONFIG_BLK_DEV_CMD640_ENHANCED=n. * pmac.c: make pmac_ide_setup_dma() return an error value and move DMA masks setup to pmac_ide_setup_device(). * Add 'struct ide_port_info' instances to legacy host drivers, pass them to ide_device_add() calls and then remove open-coded ports initialization.

2008-01-26ide: remove broken disk byte-swapping supportBartlomiej Zolnierkiewicz
Remove broken disk byte-swapping support: - it can cause a data corruption on SMP (or if using PREEMPT on UP) - all data coming from disk are byte-swapped by taskfile_*_data() which results in incorrect identify data being reported by /proc/ide/ and IOCTLs - "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers (including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing) - byte-swapping is limited to PIO transfers (for working with TiVo disks on x86 machines using user-space solutions or dm-byteswap should result in much better performance because DMA can be used) For previous discussions please see: http://www.ussg.iu.edu/hypermail/linux/kernel/0201.0/0768.html http://lkml.org/lkml/2004/2/28/111 [ I have dm-byteswap device mapper target if somebody is interested (patch is for 2.6.4 though but I'll dust it off if needed). ] Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-01-26ide: make remaining built-in only IDE host drivers modular (take 2)Bartlomiej Zolnierkiewicz
* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c file for probing PCI host drivers registered with IDE core (special case for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of the ordering in which all IDE host drivers are probed when IDE is built-in during link time. * Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific). * Move probing of ide-cris (cris arch specific) host driver before cmd640 (x86 arch specific). * Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300 (h8300 arch specific). * Add "probe_vlb" kernel parameter to cmd640 host driver and update Documentation/ide.txt accordingly. * Make IDE_ARM config option visible so it can also be disabled if needed. * Remove bogus comment from ide.c while at it. v2: * Fix two issues spotted by Sergei: - replace ENOMEM error value by ENOENT in ide-h8300 host driver - fix MODULE_PARM_DESC() in cmd640 host driver Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: Mikael Starvik <starvik@axis.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Roman Zippel <zippel@linux-m68k.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-01-26ide: don't try to unregister interfaces if 'initializing' in ide_register_hw()Bartlomiej Zolnierkiewicz
Host drivers using ide_register_hw() and 'initializing == 1': * ide-pnp - depends on ISA * ide_arm - ARM arch specific - initialized before all other host drivers * ide-cris - CRIS arch specific => IDE_ARCH_OBSOLETE_INIT is not defined - broken * ide-h8300 - H8300 arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI * buddha/q40/gayle/macide/falconide - M68K arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI Since the only host drivers which probe interfaces before the above ones are: * ali14xx/dtc2278/ht6560b/qd65xx/umc8672 - depend on ISA - require IDE_ARCH_OBSOLETE_INIT=y to work * PCI ones - depend on PCI don't try to unregister interfaces if 'initializing == 1' in ide_register_hw() (it is possible that built-in host drivers will claim all IDE interfaces but later ide-pnp host driver will try to unregister them - this change fixes it). Also skip hwif->hold check if 'initializing == 1' since it is set only by: * pmac - PPC && PMAC specific => no ISA * au1xxx-ide - MIPS && SOC_AU1200 specific => no ISA and use ide_find_port() helper to find free ide_hwifs[] slot.

2007-10-16ide: remove ->ide_dma_check (take 2)Bartlomiej Zolnierkiewicz
* Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend on BIOS for programming device/controller for DMA. Set it in cy82c693, generic, ns87415, opti621 and trm290 host drivers. * Add IDE_HFLAG_VDMA host flag for host drivers using VDMA. Set it in cs5520 host driver. * Teach ide_tune_dma() about IDE_HFLAG_TRUST_BIOS_FOR_DMA flag. * Add generic ide_dma_check() helper and remove all open coded ->ide_dma_check implementations. Fix all places checking for presence of ->ide_dma_check hook to check for ->ide_dma_on instead. * Remove no longer needed code from config_drive_for_dma(). * Make ide_tune_dma() static. v2: * Fix config_drive_for_dma() return values. * Fix ide-dma.c build for CONFIG_BLK_DEV_IDEDMA_PCI=n by adding dummy config_drive_for_dma() inline. * Fix IDE_HFLAG_TRUST_BIOS_FOR_DMA handling in ide_dma_check(). * Fix init_hwif_it8213() comment. There should be no functionality changes caused by this patch. Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
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>
2007-10-12Driver core: change add_uevent_var to use a structKay Sievers
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. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-10-11ide: add ide_set{_max}_pio() (take 4)Bartlomiej Zolnierkiewicz
* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags and set them in ht6560, cmd640, cmd64x and sc1200 host drivers. * Add set_pio_mode_abuse() for checking if host driver has a non-standard ->tuneproc() implementation and use it in do_special(). * Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find the maximum PIO mode supported by the host), also add ide_set_max_pio() wrapper for ide_set_pio() to use for auto-tuning. 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.
