Dave Müller sent a diff for the pata_oldpiix that highlighted a problem where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while the core code uses 0xFF. This turns out to have other consequences such as code doing >= XFER_UDMA_0 also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect set_dma_mode, although some drivers call back into their own set mode code from other points. Having been through the drivers I've added helpers for using_udma/using_mwdma dma_enabled so that people don't open code ranges that may change (eg if UDMA8 appears somewhere) Thanks to David for the initial bits [and added fix for pata_oldpiix from and signed-off-by Dave Mueller <dave.mueller@gmx.ch> -jg] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com> |
