    Phoronix: Intei Ironlake Receives Patches For RC6 Power Savings

    Intel Ironlake "Gen 5" graphics have been around for seven years now since being found in Clarkdale and Arrandale processors while finally now the patches are all worked out for enabling RC6 power-savings support under Linux...

      Horray! So after 5 years of using an Ironlake based laptop it finally receives proper software support for the power management features implemented in hardware

        Still using Ironlake in my daughter's laptop though it stays plugged in 24/7. Hopefully this won't affect stability. I've only just got it stable again after discovering that OpenSUSE's attempts at backporting newer DRM code (to support newer hardware) was the cause of our frequent corruption and crashes. Mind you, it'll probably be ages before this hits OpenSUSE Leap.

          You can always boot with i915.enable_rc6=0 to turn it back off if there's a problem.

            And here I thought Ironlake didn't even have RC6. I don't use my old machine much anymore, but it's still ticking when I do turn it on. Now it'll tick with a bit less power consumption

            I also saw on the mesa mailing list that the GPU hangs during VAAPI decoding are being fixed (see here). They got less annoying when proper GPU reset got implemented, but anyway, really nice to see Ironlake getting some love.

              Yep, but what if longer battery life is actually necessary?

                I wonder how many Ironlake chips there are out there in total that run linux, and how much power has been wasted in the last 7 years because this wasn't enabled sooner

                    Practically negligible compared to the wastage from all the people still running their P4 machines or other CPUs from that era.
