From 7569e8dc2213ecc47024ea5edbadc8736487d926 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 17 Feb 2007 02:40:25 +0100 Subject: ide: add ide_use_fast_pio() helper (v3) * add ide_use_fast_pio() helper for use by host drivers * add DMA capability and hwif->autodma checks to ide_use_dma() - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1) [ for the IT8211/2 in SMART mode this check shouldn't be made but since in it821x_fixups() we set DMA bit explicitly: if(strstr(id->model, "Integrated Technology Express")) { /* In raid mode the ident block is slightly buggy We need to set the bits so that the IDE layer knows LBA28. LBA48 and DMA ar valid */ id->capability |= 3; /* LBA28, DMA */ we are better off using generic helper if we can ] - ide-cris driver didn't set ->autodma [ before the patch hwif->autodma was only checked in the chipset specific hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check() function so there no behavior change here ] v2: * updated patch description (thanks to Alan Cox for the feedback) v3: * updated for scc_pata driver Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/pci/hpt366.c | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) (limited to 'drivers/ide/pci/hpt366.c') diff --git a/drivers/ide/pci/hpt366.c b/drivers/ide/pci/hpt366.c index 06dce0999105..d3f6f9da96b2 100644 --- a/drivers/ide/pci/hpt366.c +++ b/drivers/ide/pci/hpt366.c @@ -737,18 +737,13 @@ static void hpt3xx_maskproc(ide_drive_t *drive, int mask) static int hpt366_config_drive_xfer_rate(ide_drive_t *drive) { ide_hwif_t *hwif = HWIF(drive); - struct hd_driveid *id = drive->id; drive->init_speed = 0; - if ((id->capability & 1) && drive->autodma) { - if (ide_use_dma(drive) && config_chipset_for_dma(drive)) - return hwif->ide_dma_on(drive); - - goto fast_ata_pio; + if (ide_use_dma(drive) && config_chipset_for_dma(drive)) + return hwif->ide_dma_on(drive); - } else if ((id->capability & 8) || (id->field_valid & 2)) { -fast_ata_pio: + if (ide_use_fast_pio(drive)) { hpt3xx_tune_drive(drive, 255); return hwif->ide_dma_off_quietly(drive); } -- cgit v1.2.3
