      I assume you are talking about dpm. It was enabled by default on cayman GPU a while ago, but was disabled due to stability issues. The root cause was found and fixed in 3.16, so now I'm enabling dpm by default again in 3.17.

        Big Thanks! Can you say what the issue was? just with few words.

          How can i test this on archlinux? Is there any pkgbuild to build drm-next-3.17 kernel?

            Just a small typo in the driver:

                What cards don't have DPM enabled yet?

                Is it just the old r600 level gpus now?

                  Just use linux-git and change the first source line from
                  Code:
                  source=('git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git'
                  to
                  Code:
                  source=('git://people.freedesktop.org/~agd5f/linux#branch=drm-next-3.17'
                  Then makepkg, hit enter a few times to accept new default config, ready.

                    Yes, just the r6xx-based asics.

                          Next on my wishlist is better fan management for the 6870. It seems that the catalyst doesn't have this issue, but the stock AMD fan is very noisy, and the card is kept at 69C in a well-cooled case (motherboard at 32C).
                          An other user reported the issue on the phoronix forums.
                          But I guess that's a very low priority item, and I should go with a custom cooler instead.

                          Great work, AMD devs, thank you
