    Phoronix: AMD Has Massive Radeon Patch Set - Power Management!

    For AMD Radeon customers using the open-source Linux graphics driver, the Linux 3.11 kernel is going to be mega exciting! Alex Deucher of AMD posted a set of 165 kernel patches today. Most notably, there's finally Dynamic Power Management (DPM) support for R600 GPUs up through Southern Islands hardware! Yes, there's finally dynamic power management in the open-source driver. Additionally, there's initial support for AMD "Sea Islands" hardware and there's also ASPM (Active State Power Management) support...

        The major reason to use catalyst is gone!

          That's absolutely awesome. Is fan speed management also included?

          As an NVIDIA blob user I almost envy AMD users.

            I really have to say, AMD has done an amazing job with their open source drivers this past year. It'll be a huge milestone in linux history if/when these drivers become a better choice than catalyst. I get the impression it already is for older hardware (pre-HD2000 series). All I want at this point is crossfire support and I'll switch.


            Oh, and for live CD use, this is AWESOME. My GPUs heat up to as high as 85C with fans at full blast when using Parted Magic, when they're normally at about 45C or below when idle using Catalyst.

              Wow! So bridgman's claim that the HD8xxx generation would have launch day support from free software is true. Have any gentoo/ubuntu xorg-edgers people already used this?

                About damn time. They should have done this years ago. I switched from AMD to intel years ago because of the extremely poor power management in the OSS driver and AMD quickly dropping my card to "legacy" in FGLRX.

                I may consider using AMD graphics again some day if they keep this up. Good job AMD, please keep this up!

                  Thank....GOD... I was just considering switching my Desktop-Replacement laptop back over to Fedora the other day and I decided against it due to power management. VERY happy to see these get posted, and a biiiig shoutout to the entire Radeon team over at AMD, Alex, Bridgman and Christian and anyone else I may be missing-- you guys are awesome

                    There's also a reasonably good chance that Ubuntu 13.10 will use the 3.11 Linux Kernel. That'll be quite the OOB experience for R600+ GPU users like myself!

                      I literately danced for joy seeing this headline! Now I'll be able to use linux again! (My laptop uses a A4 chip and wouldn't suspend resume with the blob).

                      Thank you, Thank you, Thank you AMD!

                        Fuck yeah!! Bridgman told us before that catalyst PM code is bigger than entire FOSS 3D stack, I will be happy about his comment on that.

                          If AMD keeps this up people are going to start thinking AMD cares about open source.

                            It is hidden behind a kernel command-line parameter for now, so it might not be enabled by default until Ubuntu 14.04 LTS. But yeah this is insanely awesome and if this actually works I am kicking out Catalyst in a heartbeat.

                              With this the open source driver is feature complete. It now supports 2d, 3d, suspend/resume and power management.

                              Yay! We now have an alternative to Intel!
