2008-04-26qd65xx: always use ->selectproc methodBartlomiej Zolnierkiewicz
qd_select() checks itself whether timings should be reprogrammed so remove superfluous qd_timing_ok() and always use ->selectproc method (rename qd_select() to qd65xx_select() while at it). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: use ide_find_port() in legacy VLB host drivers (take 2)Bartlomiej Zolnierkiewicz

2008-02-02ide: add ->port_init_devs method to ide_hwif_tBartlomiej Zolnierkiewicz
* Add ->port_init_devs method to ide_hwif_t for a host specific initialization of devices on a port. Call the new method from ide_port_init_devices(). * Convert ht6560b, qd65xx and opti621 host drivers to use the new ->port_init_devs method.

2008-02-01ide: delete filenames/versions from commentsBartlomiej Zolnierkiewicz
Delete filenames/versions from comments. I'm leaving decisions about adding DRV_VERSION defines and MODULE_VERSION()-s to maintainers of the respective drivers. While at it: * Remove unused VERSION define from ide.c. * Remove unused/stale DRV_VERSION define from au1xxx-ide.c. 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>
2007-10-20qd65xx: remove pointless qd_{read,write}_reg() (take 2)Bartlomiej Zolnierkiewicz

* Add ide_device_add() helper and convert host drivers to use it instead of open-coded variants. * Make ide_pci_setup_ports() and do_ide_setup_pci_device() take 'u8 *idx' argument instead of 'ata_index_t *index'. * Remove no longer needed ata_index_t. * Unexport probe_hwif_init() and make it static. * Unexport ide_proc_register_port(). There should be no functionality changes caused by this patch (sgiioc4.c: ide_proc_register_port() requires hwif->present to be set and it won't be set if probe_hwif_init() fails).

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.

PIO4 is a maximum PIO mode supported by a driver.

2007-03-03ide: make legacy IDE VLB modules check for the "probe" kernel params (v2)Bartlomiej Zolnierkiewicz
Legacy IDE VLB host drivers didn't check for "probe" options when compiled as modules, which was obviously wrong as we don't want module to poke at random I/O ports by simply loading it.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
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!
