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/setup-pci.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/ide/setup-pci.c') diff --git a/drivers/ide/setup-pci.c b/drivers/ide/setup-pci.c index f620da42e157..3d101f73f910 100644 --- a/drivers/ide/setup-pci.c +++ b/drivers/ide/setup-pci.c @@ -438,8 +438,6 @@ static void ide_hwif_setup_dma(struct pci_dev *dev, ide_pci_device_t *d, ide_hwi * Set up BM-DMA capability * (PnP BIOS should have done this) */ - /* default DMA off if we had to configure it here */ - hwif->autodma = 0; pci_set_master(dev); if (pci_read_config_word(dev, PCI_COMMAND, &pcicmd) || !(pcicmd & PCI_COMMAND_MASTER)) { printk(KERN_ERR "%s: %s error updating PCICMD\n", -- cgit v1.2.3
