d2ead3eaf8a4bf92129eda69189ce18a6c1cc8bd is the first bad commit commit d2ead3eaf8a4bf92129eda69189ce18a6c1cc8bd Author: Alex Deucher alexander.deucher@amd.com Date: Thu Dec 13 09:55:45 2012 -0500
drm/radeon/kms: add evergreen/cayman CS parser for async DMA (v2)
Allows us to use the DMA ring from userspace. DMA doesn't have a good NOP packet in which to embed the reloc idx, so userspace has to add a reloc for each buffer used and order them to match the command stream.
v2: fix address bounds checking
