Ping. 3.6 merge window is approach fast and I think I'd be good to get this in ... Or something similar, based on the hsw ratio between downclock and upclock limit, but with the slightly bigger thresholds used by ivb/snb for upclocks maybe? -Daniel -- Daniel Vetter Mail: dan...@ffwll.ch Mobile: +41 (0)79 365 57 48 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
