Hi Michel,
In regards to the Alpha platform: Jeff Wiedemeier was able to get things to work after applying the attached small patch. He says:
What was happening is that the offset was a system-relative representation of the address and the (agpmem->bound) was bus-relative, so it couldn't find the right agpmem.
This patch makes the offset bus-relative before the scan (and with this patch, DRI/DRM is working on a Marvel...)
If it looks OK to you, can you add it?
Thanks,
--david
