Definitions look correct. If I noticed any discrepancies during testing, I'll flag it.

Dave Airlie mailto:airlied@gmail.com Tuesday, May 20, 2014 7:54 PM Hey,
So this set is pretty close to what I think we should be merging initially,
Since the last set, it makes fbcon and suspend/resume work a lot better,
I've also fixed a couple of bugs in -intel that make things work a lot better.
I've bashed on this a bit using kms-flip from intel-gpu-tools, hacked to add 3 monitor support.
It still generates a fair few i915 state checker backtraces, and some of them are fairly hard to work out, it might be we should just tone down the state checker for encoders/connectors with no actual hw backing them.
Dave.
