... why the IDE driver works
Don't know. Maybe the ATAPI devices are configured to PIO?
It's actually configured to UDMA33. https://bugzilla.novell.com/attachment.cgi?id=145363
if we're gonna implement check_atapi_dma() for ali, what condition should we check against?
I guess maybe we can use the same logic of pata_pdc2027x for pata_ali. The logic seems to be what the Windows atapi driver uses. And some hardware vendors design their hardware specifically for that logic...
Hmmm... My memory of MMC is fading. When ripping a CD or writing one, does MMC use READ/WRITE commands? Or are there different dedicated commands? If we don't pay a lot of penalty for common cases, I think we better default to what windows defaults to. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
