    Phoronix: AMD Releases ACPI Header For Open-Source GPU Driver

    For those that didn't notice, this week AMD released a new header that defines the AMD ACPI interface used for laptops, PowerXpress, and chipset-specific functionality...

    I think it's one of the biggest gaps yet missing from the opensource AMD drivers. While on a desktop you can kind-of shrug it off, on a laptop I don't consider the opensource drivers a credible alternative because of their missing power management support when compared to catalyst.

    Thanks to John Bridgman and to all the open AMD devs working on this, it's very appreciated!

      Good, its about time power management improved on the OSS drivers. Currently the oss drivers are pretty useless on a dedicated mobile card, poor battery life and temps even when I set the profile to low.

        Nvidia: "lololol, why you do this AMD? PM bits are supposed to be 100% proprietary."

          Props to AMD for doing this so the jakes on you now, nVidia

          With each bit of info AMD releases, the pressure on nvidia ratchets up. While not to hijack this thread suffice it to say that nvidia should release at least the register, PM and command programming docs at minimum for their cards.

          Otherwise in due time even the nvidia lovers might want to jump ship to AMD or even Intel!

            Ohhhh. This is great news. Seriously, with everyone (including me :-) having portable devices, power management is very important (if linux dramatically reduces battery life, then one won't use linux on a portable device). So this being done will mean I'll be able to use linux on my laptop again. Thank you AMD for deciding to work on this!

              not really. If you go on winehq, you see that most people have issues gaming with amd cards, and the nvidia ones usually work fine.

                  IIRC, this has a lot to do with historical issues surrounding fglrx and WineD3D that don't say much about current driver quality.

                    WHO CARES???
                    0.0000000001% care about gaming, therefore NOT IMPORTANT.

                      So, if i understand this correctly it means that i can finally use my 6870 graphics card with the oss drivers without the fans blowing at full speed?
                      Please, DON'T give me the suggestion for dynpm or low/mid profile. They all had issues last time i used it. I want dynpm to work without it putting a tornado in my pc case.

                        This is the first stepping stone to *fix* dynpm, but there is still work to do before it is end-user ready. So not yet, but hopefully soon a working dynpm can be made the default.

                        As for low/mid profiles, low does have some issues on some hardware, but mid should work on all hw since 2.6.39 so if you haven't tested it recently, you might want to give it another try.

                            If I read that correctly there is only a fraction of one gamer out there (approximately seven one thousandth of a gamer).
                            Hyperbole is for demagogues, satirists and fools. Which are you?

                              Seriously though, there are people who use their computers for work.

                              It might be hard for some of our Workraft!111!! friends to believe, but they do exist!

                              And for them, decent 3d performance + stable 2d + decent powersaving is a godsend.
