Hi,
The radeon benchmark test fails on my non coherent DMA 745x PPC machine
(see the kernel log excerpt below). The test was performed with a fresh
copy of the airlied/drm-2.6/drm-next branch and the radeon driver was
forced to PCIGART mode. The radeon GTT<->VRAM copy test however works
fine. Let me know, if I should do more testing.
Thanks!
Best regards,
Gerhard
