There is also a bit of follow-up work needed to optimize DPCD read/writes. They can be done together after this. I don't know if you had a chance to look at this series in detail. But if you did, do you see any blockers for accepting this series? -DK _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
