Here is the original post with the RFC for these patches. http://lists.freedesktop.org/archives/intel-gfx/2012-November/022330.html I don't believe there have been any major changes in the driver code. So, what's changed since last time? I've pushed 4 patches which implement tests for the new ring to i-g-t: http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/commit/?id=bafbbf1cc8663fa192c57152f2c13a81e68f9089 http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/commit/?id=21e7e342c14a69d62a24a9bce89b66c3ef0fd208 http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/commit/?id=cf73a1f241542dadb49ae2c6d491c725218a68e8 (Fixed by Chris Wilson) http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/commit/?id=f187990bbf4396c7ae1796030377301bdd493852 I've pushed the libdrm patch to enable using the VECS ring: http://cgit.freedesktop.org/mesa/drm/commit/?id=011999927f76a7e9ba8f047fae4b4e084da6c2c3 I've run this series on a subset of intel-gpu-tools suite, and don't see any failures which aren't in nightly. I tend to skip display tests in my regression runs. Since originally publishing the RFC patches, I've had to do two pretty major rebases over VLV support, HSW support, and a lot of random infrastructure changes. I caught a couple of logical conflicts in doing this, but it's likely I've missed at least one. Also, as mentioned above, these are only lightly tested wrt to display.
