Linux 4.8 and Skylake (Dell XPS 9550)

I’ve had a Dell XPS 9550 since around February. It’s a fantastic laptop but there definitely have been teething pains with the Skylake processor and Linux, specifically related to power management.

Today I installed Linux kernel 4.8-rc5 and got a nice surprise vs 4.7.2 which I was running.

That’s quite a bit better than observed with 4.7.2 and far, far better than 4.5.X when I first got the laptop.

  1. Could you please be so kind specify your kernel options and oter power management relevant parameters ?

    1. Fedora 24 with 4.8 kernel from the rawhide, nodebug repository.

      I think I had tuned running at that point using the laptop powersave profile.
