    Alex Deucher has improved the Radeon Dynamic Power Management (DPM) open-source driver support so it now works more reliably on newer AMD GPUs...

    Excellent work. Bad side of it that Linus will not be happy, more patch is coming. RCxxxx will be bigger and bigger.

    Thank you Alex.

        Does this mean the 7000 and 8000 series of AMD cards can be used with the radeon driver for stuff like compositing for your window manager with 3.14? I am considering building a new PC and would like to use AMD graphics with the FOSS drivers.

          It looks like those series have had some action, judging by the commit log. I'm planning on getting one of these new Kaveri APUs next year, so with any luck this will be in good shape by then.

            Yeah, I'm interested in this archi, too. AND cant wait for the drivers to reach a state everyday tasks will just work with the default kernel drivers. Mmmm, good times.

              This patch is mainly targeting R9 290/290X.

              RadeonSI(open source driver for 7700 and newer cards) can handle desktop composition without a glitch even back to Kernel 3.12,
              Just add radeon.dpm=1 parameter to kernel boot line.

                Meanwhile, the latest rc still crashes my AMD A8-6600K since DPM doesn't work on it.

                  I can confirm that for HD 7950 - excellent compositing and working DPM since kernel 3.11 - while performance-wise dpm would not even be needed for compositing - is it.
                  gaming performance is also ok with mesa 10.
