2008-10-10ide: add proper PCI PM support (v2)Bartlomiej Zolnierkiewicz
* 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.

2008-07-24ide: prefix messages from IDE PCI host drivers by driver nameBartlomiej Zolnierkiewicz
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). As a bonus this provides nice code savings for some drivers: text data bss dec hex filename 3826 112 8 3946 f6a drivers/ide/pci/amd74xx.o.before 2786 112 8 2906 b5a drivers/ide/pci/amd74xx.o.after 764 108 0 872 368 drivers/ide/pci/cs5520.o.before 680 108 0 788 314 drivers/ide/pci/cs5520.o.after 1680 112 4 1796 704 drivers/ide/pci/generic.o.before 1155 112 4 1271 4f7 drivers/ide/pci/generic.o.after 7128 792 0 7920 1ef0 drivers/ide/pci/hpt366.o.before 6984 792 0 7776 1e60 drivers/ide/pci/hpt366.o.after 2800 148 0 2948 b84 drivers/ide/pci/pdc202xx_new.o.before 2523 148 0 2671 a6f drivers/ide/pci/pdc202xx_new.o.after 2831 148 0 2979 ba3 drivers/ide/pci/pdc202xx_old.o.before 2683 148 0 2831 b0f drivers/ide/pci/pdc202xx_old.o.after 3776 112 4 3892 f34 drivers/ide/pci/piix.o.before 2804 112 4 2920 b68 drivers/ide/pci/piix.o.after 4693 116 0 4809 12c9 drivers/ide/pci/siimage.o.before 4600 116 0 4716 126c drivers/ide/pci/siimage.o.after Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag for Motorola-Sandpoint platform to sl82c105 host driver. * Disable ide_generic host driver in arch/ppc/configs/sandpoint_defconfig and enable sl82c105 one. * Remove ppc_ide_md hooks from arch/ppc/platforms/sandpoint.c - no need for them (sl82c105 host driver takes care of all this setup). * Then remove no longer needed <linux/ide.h> include. * Also update arch/ppc/platforms/sandpoint.h. Unfortunately (unlike lopec's case) sl82c105 host driver was not enabled in defconfing so there is a funcionality change.

Looking at arch/ppc/configs/lopec_defconfig: ... CONFIG_IDE_GENERIC=y CONFIG_BLK_DEV_IDEPCI=y # CONFIG_IDEPCI_SHARE_IRQ is not set # CONFIG_BLK_DEV_OFFBOARD is not set CONFIG_BLK_DEV_GENERIC=y # CONFIG_BLK_DEV_OPTI621 is not set CONFIG_BLK_DEV_SL82C105=y ... there should be no functional changes unless somebody preferred to disable sl82c105 host driver and use only ide_generic one (but why would anybody want to do such thing :-). PS It seems that lopec_defconfig hasn't been updated for ages but if somebody is going to do it please look into disabling IDE_GENERIC and BLK_DEV_GENERIC config options. Thanks.

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 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>

* 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.

2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

2007-07-09ide: make void and rename ide_dma_timeout() methodSergei Shtylyov
Since ide_dma_timeout() method's result is discarded, make it return 'void'. While at it, drop 'ide_' from the method's name, drop the '__' prefix from the default method's name, and do some cleanups in this method driver-wise: - in ide-dma.c, au1xxx-ide.c, and pdc202xx_old.c, define/use 'hwif' variable; - in au1xxx-ide.c, get rid of commented out printk(); - in sl82c105.c, get rid of unnecessary variables.
