Hi This is an initial set of patches related to InfoFrames I developed. They're based on a few bugs I can reproduce and also on the register specifications. The first patch is candidate to stable, but patches 2, 3 and 4 could also be (they fix my system when I boot only with an HDMI monitor and nothing else, not even LVDS, but I couldn't get any bug reporter to confirm this yet). Patch 3 should also fix non-hdmi-related problems. How did I test? I change intel_hdmi.c and set the Pixel Repetition field of the AVI InfoFrame to '1' for every possible mode, so one of my monitors (only that one...) displays only half of the pixels when it recognizes the AVI InfoFrame. When it does not recognize them, the image is normal. I tested this on one Gen 4 machine, Ironlake, Sandy Bridge and Ivy Bridge. They all seem to work now. The biggest source of problems I had was when booting with only an HDMI monitor (not even an LVDS panel): this case was tested on SNB and IVB. I will still write more patches for this in the near future, but set this looks good right now and fixes all the problems I can reproduce. So the other patches can go in a second round. Thanks, Paulo -- Paulo Zanoni
