To be clear, because I don't think I listed that case, with 3.17.0-rc2-ARCH-00040-gff0c57ac7043 and i915.enable_fbc=1 the idle power consumption goes back down to under 7W, which is about back to normal. There does seem to be a roughly +500mW regression since 3.13, but it's a little hard to tell because of the sampling noise in the power information as reported by powertop. Is there a systematic, large-scale effort to obtain baseline power data over time on various configs? _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
