Ok, that took all evening. And, I don't have a fix, but I do know a lot more about the problem. To recap: On Sandybridge, sometimes, when you simultaneously change two outputs, one of them turns into stripes, or as solid color. Here's how I reproduce it: First, connect

[Intel-gfx] [PATCH] drm/i915: add GPU frequency control file

Mainly for use in debugging and benchmarking, this file allows the user to control the max frequency used by the GPU. Frequency may still vary based on workload (if the frequency is set to higher than the minimum) but won't go over the newly set value. Signed-off-by: Jesse Barnes

[Intel-gfx] [PATCH 1/2] drm/i915: apply timing generator bug workaround on CPT and PPT

On CougarPoint and PantherPoint PCH chips, the timing generator may fail to start after DP training completes. This is due to a bug in the FDI autotraining detect logic (which will stall the timing generator and re-enable it once training completes), so disable it to avoid silent DP mode setting
