2007-10-19ide: set drive->autotune in ide_pci_setup_ports()Bartlomiej Zolnierkiewicz
Majority of host drivers using IDE PCI layer set drive->autotune, the only exceptions are: generic.c ns87415.c rz1000.c trm290.c * no ->set_pio_mode method it821x.c: * if memory allocation fails drive->autotune won't be set (but there also won't be ->set_pio_mode method in such case) piix.c: * MPIIX controller (no ->init_hwif method so also no ->set_pio_mode method) However if there is no ->set_pio_mode method there are no changes in behavior w.r.t. PIO tuning so always set drive->autotune in ide_pci_setup_ports(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Add ->mwdma_mask and ->swdma_mask to ide_pci_device_t. * Set ide_hwif_t DMA masks using DMA masks from ide_pci_device_t in setup-pci.c::ide_pci_setup_ports() (iff DMA base is valid and ->init_hwif method may still override them). * Convert IDE PCI host drivers to use ide_pci_device_t DMA masks. While at it: * Use ATA_{UDMA,MWDMA,SWDMA}* defines. * hpt34x.c: add separate ide_pci_device_t instances for HPT343 and HPT345. * serverworks.c: fix DMA masks being set before checking DMA base. v2: * Add missing masks to DECLARE_GENERIC_PCI_DEV() macro.

2007-10-16ide: remove hwif->autodma and drive->autodmaBartlomiej Zolnierkiewicz
* 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 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.

* 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.

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!
