Hmm, the plan was not to affect idle power consumption. Can you log measured frequency and rc6 state whilst idle? I wonder if something is preventing the system from idling. Maybe we need something like perf timechart to measure wakeups over time. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
