I talked with chris wilson (the intel gpu driver writer) on irc a bit about the Braswell chips. For now there is no dedicated table for up clocking and downclocking the GPU used in kernel. That basically means: it always needs to have 99% load to go up from one performance state to the next higher. This is causing skips with lanczos3 scaler, when e.g. upscaling from 720p to 1080p.
Here is code, that loads the default tables, that upclock earliert (at 85%): http://sprunge.us/PQMf
