From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Implement the missing w/a for back to back FBC disable + plane update on glk+. The scariest part of this is that we now start to use flip nuke so that we can avoid the w/a (as it would cost us one extra frame for every plane update). Hopefully my "can we flip nuke safely?" check is good enough. There's a bit of cleanup mixed in since there was all kinds of crap in my way. The state of the code is still not pretty but seemed to work well enough in my limited testing.
