[MPlayer-dev-eng] DMA or not DMA

[Attila Kinali]

Hi,

In a discussion on the open-graphics mailinglist the question DMA 
came up. Basicaly why players like MPlayer don't use DMA but do 
instead a mem2pci/agp copy.

>From the discussion, i musst say, that i don't see a real
problem to use DMA and that it would gain some performance.

If DMA with MPlayer is just a matter of setting up a DMA-channel,
then i will try to patch mga_vid to use it instead (but that
wont be before the christmas break and after the 2.6 port is finished)

Do you see any problems with DMA or would it be just a straight
forward implement and forget thing ?
