amd74xx: use ->pio_mode value to determine pair device speed

2010-01-19T09:52:32+00:00

Use the current PIO mode value instead of the current transfer speed of the pair device on the port to determine PIO commmand timings used for both devices on the port. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: David S. Miller

ide: change ->set_dma_mode method parameters

2010-01-19T09:45:29+00:00

Change ->set_dma_mode method parameters to match ->set_dmamode method used in struct ata_port_operations. Signed-off-by: Bartlomiej Zolnierkiewicz

ide: change ->set_pio_mode method parameters

ide: fix ->init_chipset method to return 'int' value

2009-03-24T22:22:53+00:00

* Return 0 instead of dev->irq in ->init_chipset implementations. * Fix ->init_chipset method to return 'int' value instead of 'unsigned int' one. This fixes ->init_chipset handling for host drivers (cs5530, hpt366 and pdc202xx_new) for which it is possible for this method to fail. Signed-off-by: Bartlomiej Zolnierkiewicz

amd74xx: remove no longer needed ->init_hwif method

2009-03-24T22:22:52+00:00

This is now handled by core IDE PCI code. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz

amd74xx: use ide_pci_is_in_compatibility_mode()

2009-03-24T22:22:48+00:00

Fix ->init_hwif to check if IDE PCI controller is in compatibility mode instead of checking for hwif->irq == 0. Signed-off-by: Bartlomiej Zolnierkiewicz

amd74xx: workaround unreliable AltStatus register for nVidia controllers

2008-12-02T19:40:03+00:00

It seems that on some nVidia controllers using AltStatus register can be unreliable so default to Status register if the PCI device is in Compatibility Mode. In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to . * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bugs #11659 and #10216). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people and distributions use) it never worked correctly. ] Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.
