I mean from one point in sysmem to the other. Is it memcpy or is there a faster hardware dma thing I can use? Or is dma for sys ram to gs ram only?

Thanks.

...fastest way is to use uncached accelerated buffer and lq/sq instructions (8 'lq' in the row following 8 'sq' in the row). Limitation is that your blocks must have 16 byte alignment...
