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/it821x.c | 22 +++++----------------- 1 file changed, 5 insertions(+), 17 deletions(-) (limited to 'drivers/ide/pci/it821x.c') diff --git a/drivers/ide/pci/it821x.c b/drivers/ide/pci/it821x.c index 752a142ca89b..f3391a8698ac 100644 --- a/drivers/ide/pci/it821x.c +++ b/drivers/ide/pci/it821x.c @@ -537,10 +537,11 @@ static void __devinit init_hwif_it821x(ide_hwif_t *hwif) struct it821x_dev *idev = kzalloc(sizeof(struct it821x_dev), GFP_KERNEL); u8 conf; - if(idev == NULL) { + if (idev == NULL) { printk(KERN_ERR "it821x: out of memory, falling back to legacy behaviour.\n"); - goto fallback; + return; } + ide_set_hwifdata(hwif, idev); hwif->atapi_dma = 1; @@ -589,27 +590,14 @@ static void __devinit init_hwif_it821x(ide_hwif_t *hwif) hwif->drives[0].autotune = 1; hwif->drives[1].autotune = 1; - if (!hwif->dma_base) - goto fallback; + if (hwif->dma_base == 0) + return; hwif->ultra_mask = 0x7f; hwif->mwdma_mask = 0x07; if (hwif->cbl != ATA_CBL_PATA40_SHORT) hwif->cbl = ata66_it821x(hwif); - - /* - * The BIOS often doesn't set up DMA on this controller - * so we always do it. - */ - - hwif->autodma = 1; - hwif->drives[0].autodma = hwif->autodma; - hwif->drives[1].autodma = hwif->autodma; - return; -fallback: - hwif->autodma = 0; - return; } static void __devinit it8212_disable_raid(struct pci_dev *dev) -- cgit v1.2.3-55-g7522
