Thanks, that's what I needed to know. One last question - would you know
whether Radeon AGP has a restriction of not being able to DMA into non-AGP
memory ? I am providing a table with physical addresses and all, but
transfers below 0x4000000 fail - and this is the value written in
CP_RB_BASE, which also coincides with statement from agpgart that only
439mb out of 512 are available for agp memory. Is there a way to query
agpgart about which memory is agp without acquiring it ?
thanks !
