From 9ff6f72f432364991d68e99cae72cb141c166e70 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 16 Oct 2007 22:29:58 +0200 Subject: ide: remove hwif->autodma and drive->autodma * 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 --- drivers/ide/pci/slc90e66.c | 7 ------- 1 file changed, 7 deletions(-) (limited to 'drivers/ide/pci/slc90e66.c') diff --git a/drivers/ide/pci/slc90e66.c b/drivers/ide/pci/slc90e66.c index 3e6ed73feb6..fa8df6d4383 100644 --- a/drivers/ide/pci/slc90e66.c +++ b/drivers/ide/pci/slc90e66.c @@ -133,8 +133,6 @@ static void __devinit init_hwif_slc90e66 (ide_hwif_t *hwif) u8 reg47 = 0; u8 mask = hwif->channel ? 0x01 : 0x02; /* bit0:Primary */ - hwif->autodma = 0; - if (!hwif->irq) hwif->irq = hwif->channel ? 15 : 14; @@ -157,11 +155,6 @@ static void __devinit init_hwif_slc90e66 (ide_hwif_t *hwif) if (hwif->cbl != ATA_CBL_PATA40_SHORT) /* bit[0(1)]: 0:80, 1:40 */ hwif->cbl = (reg47 & mask) ?
