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: fix host drivers depending on ide_generic to probe for interfaces (take 2)Bartlomiej Zolnierkiewicz
* Add mpc8xx_ide_probe() to mpc8xx.c and call it from probe_for_hwifs(). * Convert ide_arm, ide-cris, ide-h8300, ide-pnp, buddha, falconide, gayle, macide, q40ide, cmd640 and mpc8xx host drivers to use ide_device_add(). This removes dependency on ide_generic for these drivers so update ide/Kconfig accordingly. v2: * ide_arm build fix (s/ide_device_idx/ide_device_add/) (Thanks to Christoph Lameter <clameter@sgi.com> for reporting the problem).

2008-01-26ide: move ide_arm_init() call from init_ide_data() to ide_init()Bartlomiej Zolnierkiewicz
* Remove ide_init_port_data() call from ide_arm_init() and move ide_arm_init() call from init_ide_data() to ide_init(). This patch is a preparation for the future changes (and as a side-effect makes obsolete "idex=io[,ctl[,irq]]" kernel parameters work for ide_arm).

2008-01-26ide: drop 'initializing' argument from ide_register_hw()Bartlomiej Zolnierkiewicz
* Rename init_hwif_data() to ide_init_port_data() and export it. * For all users of ide_register_hw() with 'initializing' argument set hwif->present and hwif->hold are always zero so convert these host drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw() instead (also no need for init_hwif_default() call since the setup done by it gets over-ridden by ide_init_port_hw() call). * Drop 'initializing' argument from ide_register_hw().

2008-01-26ide: add ide_init_port_hw() helperBartlomiej Zolnierkiewicz
* Add ide_init_port_hw() helper. * rapide.c: convert rapide_locate_hwif() to rapide_setup_ports() and use ide_init_port_hw(). * ide_platform.c: convert plat_ide_locate_hwif() to plat_ide_setup_ports() and use ide_init_port_hw(). * sgiioc4.c: use ide_init_port_hw(). * pmac.c: add 'hw_regs_t *hw' argument to pmac_ide_setup_device(), setup 'hw' in pmac_ide_{macio,pci}_attach() and use ide_init_port_hw() in pmac_ide_setup_device(). This patch is a preparation for the future changes in the IDE probing code. There should be no functionality changes caused by this patch.

* hpt34x.c: disable DMA masks for HPT345 (hwif->autodma is zero so DMA won't be enabled anyway). * trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag (hwif->autodma is zero so DMA won't be enabled anyway). * Check noautodma global variable instead of drive->autodma in ide_tune_dma(). This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris, au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers. * Remove hwif->autodma (it was not checked by IDE core code anyway) and drive->autodma (was set by all host drivers - except HPT345/TRM290 special cases - unless "ide=nodma" was used). While at it: - remove needless printk() from icside.c - remove stale FIXME/comment from ide-probe.c - don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c (this setting was always later over-ridden by host drivers anyway) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

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.

* 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).

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.

2007-03-17ide: remove CONFIG_IDEDMA_{ICS,PCI}_AUTO config optionsBartlomiej Zolnierkiewicz
All modern distributions have been setting these options to "y" for ages. (additionally "n" cases have been obsoleted for few years). Therefore use DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer needed CONFIG_IDEDMA_AUTO). This fixes DMA support for rare configurations where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used to enable DMA support and which were forced to PIO mode by "ide: don't allow DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch. There is no functionality loss because "ide=nodma" kernel option is still available.

* since ide_hwif_t.ide_dma_host_on is called either when drive->using_dma == 1 or when return value is discarded make it void, also drop "ide_" prefix * make __ide_dma_host_on() void and drop "__" prefix v2: * while at it rename atiixp_ide_dma_host_on() to atiixp_dma_host_on() and sgiioc4_ide_dma_host_on() to sgiioc4_dma_host_on().

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!
