2008-10-11ide: add proper PCI PM support (v2)Bartlomiej Zolnierkiewicz1-2/+4
* Keep pointer to ->init_chipset method also in struct ide_host and set it in ide_host_alloc_all(). * Add ide_pci_suspend() and ide_pci_resume() helpers (default ->suspend and ->resume implementations). * ->init_chipset can no longer be marked __devinit. * Add proper PCI PM support to IDE PCI host drivers (rz1000.c and tc86c001.c are skipped for now since they need to be converted from using ->init_hwif to use ->init_chipset instead). v2: * Cleanup CONFIG_PM #ifdef-s per akpm's suggestion.

2008-07-25ide: prefix messages from IDE PCI host drivers by driver nameBartlomiej Zolnierkiewicz1-6/+9
Prefix messages from IDE PCI host drivers by driver name instead of marketed chipset name (it is still possible to exactly identify the particular chipset basing on driver messages).

2008-07-23ide: filter out "default" transfer mode values in set_xfer_rate()Bartlomiej Zolnierkiewicz1-1/+0
* Filter out "default" transfer mode values (0x00 - default PIO mode, 0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted /proc/ide/hd?/settings:current_speed setting. Allowing "default" transfer mode values is a dangerous thing to do as we don't support programming controller to the "default" transfer mode and devices often use different values for the default and maximum PIO mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay programmed for higher PIO mode while device will use the lower PIO mode. There is no functionality loss as by using special IOCTLs device can still be programmed to "default" transfer modes (it is only useful for debugging/testing purposes anyway). * Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was previously used by few host drivers to program the controller to PIO0 timings for "default" transfer mode == 0x01 (although some host drivers would program invalid PIO timings instead). * Cleanup ide_set_xfer_rate() and add BUG_ON().

2008-07-15ide: eliminate FIT() macroHarvey Harrison1-7/+7
Replace the FIT() macro with the kernel-provided clamp_val() macro. FIT was always being called with a member of a struct ide_timing, which are shorts, and constant constraints for the min and max. Thus we can use clamp_val, rather than clamp_t.

2007-10-12amd74xx/via82cxxx: use ide_tune_dma()Bartlomiej Zolnierkiewicz1-11/+4
* Use ide_tune_dma() in amd74xx/via82cxxx driver, this fixes following bugs: - DMA capability bit not being checked on the device - DMA blacklist not being checked - DMA mode being programmed even if drive->autodma == 0 (thus possibly destroying PIO timings) * Bump driver version.

2007-10-12ide: add ide_set{_max}_pio() (take 4)Bartlomiej Zolnierkiewicz1-10/+7
* 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.

2007-10-12ide: move ide_rate_filter() calls to the upper layer (take 2)Bartlomiej Zolnierkiewicz1-3/+1
* 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. There should be no functionality changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-12ide: add missing ide_rate_filter() calls to ->speedproc()-sBartlomiej Zolnierkiewicz1-0/+2
* 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.

2007-10-10drivers/firmware: const-ify DMI API and internalsJeff Garzik1-1/+1
Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.
