Hi Matthew, here is the patch I've mentioned on irc today: http://cgit.freedesktop.org/~vivijim/drm-intel/commit/?h=psr_for_mjg59&id=83809492138f2395bfb12c19e6de916de64b9246 And I prepared this branch for now: http://cgit.freedesktop.org/~vivijim/drm-intel/log/?h=psr_for_mjg59 I'm not sending yet the patches because I still face the missed screen during boot that you had mentioned. As soon as I fixed it I'll submit everything. Thanks, Rodrigo.
