2014-11-13Add nodma optionsSamuel Thibault
Some very slow qemu instances would eventually trigger DMA timeouts, let's give a way to disable DMA there, it does not actually slow down operations anyway. * linux/src/drivers/block/ide.h (ide_drive_s): Add nodma field. * linux/src/drivers/block/ide.c (do_identify): Do not call dmaproc(ide_dma_check) when nodma is 1. (ide_setup): Add nodma option.

2012-12-21ide: Increase WAIT_DRQ to accomodate some CF cards and SSD drives.David S. Miller
Based upon a patch by Philippe De Muyter, and feedback from Mark Lord and Robert Hancock. As noted by Mark Lord, the outdated ATA1 spec specifies a 20msec timeout for setting DRQ but lots of common devices overshoot this. Signed-off-by: David S. Miller <davem@davemloft.net> (cherry picked from Linux kernel commit 602da297e293eb2cbd28dcdbbe247593a46a853a) * linux/src/drivers/block/ide.h (WAIT_DRQ): Increase to 1 s.
