Jeff, I've really been trying to figure this out but with no success so far. I don't know if there's a bug somewhere or if I'm forgeting to make some step.
I need to access the contents of a DMA buffer allocated from AGPGART within the DRM. Initialy I attemped to use the "buf->address" directly which pointed to e0000000, but I got a kernel oops: Unable to handle kernel paging request at virtual address e0000002 printing eip: ... The "buf->address" has the same value as "buf->offset" - this is even quite explicity in the DRM(addbufs_agp) code. Initially I found it quite strange but then I read somewhere that the kernel dealt with the physical addresses directly. So why isn't this working?
