    Phoronix: Open-Source ATI Evergreen Support Arrives

    Months after the ATI Radeon HD 5000 series (known by the "Evergreen" family codename) was introduced, AMD has finally pushed out the first bits of open-source code. This morning if you are to checkout the xf86-video-ati DDX driver branch there is initial user-space mode-setting support for the Radeon HD 5000 series GPUs...

      Excellent! Looks like I won't have to be using fglrx for long!

          Great news. Why bother with usermode support for new hardware, though?

            Awesome, been looking forward to this!

              Enterprise distros still rely on usermode drivers.

              New major releases of enterprise distros will undoubtedly move to kernel modesetting but the versions in the field need to be maintained as well, so I expect new GPU support will be going into usermode drivers for a few more years.

                Excellent
                The code says ...

                ...
                +#define PCI_CHIP_CEDAR_68E0 0x68E0
                ...

                Very nice!
                Ubuntu 10.10 will be a gorgeous release

                  Great. I just had to give it a spin . Idle power consumption is 30 watt higher than fglrx (with ForceLowPowerMode it's down to 17 watt higher), but that fan is one noisy son of a biatch. Other than that it works great.

                    Thanks for the power figures. Sounds interesting. Yes, idle power consumption is something that all chips from R600 and above needs to be worked on.
                    I don't own an Evergreen (yet) but I look forward at it after my R600 since they are known to have very good idle power uptake for such a powerful card. And if they're capable of doing hybrid GPU one day... *dreams*

                    @ Michael
                    Oh noes! Stop the goodness. I mean, don't stop it, but spread it over the days. It's starting to become an overdoese. I might lack these good news in the rest of the week.

                      Very impressive!

                      It is amazing how much work there is being put into these drivers.

                        Apparently it's tricky stuff... I was playing around a little with the engine and memory clocks, setting them to the same values fglrx uses when idle, managed to shave off another 3 watts, then all of a sudden the display went into DPMS off mode and had to reisub.

                        I think there's no code yet to lower GPU voltage in the oss driver. Once/if that gets in I think we should come pretty close to fglrx idle power consumption.

                          Which is vital for both the desktop/laptop cards - to save energy and the earth from pollution.

                          In notebooks its a must.

                            Ouch. Good to have that magic sysrq in kernel. Humm. Strange that it switches like off when you just use the same values. But then fglrx probably knows more where to do what and how you can save more without having the HW go crazy. But I hope that this is still to come for the free driver(s).
                            Playing with voltages might be a difficult game. Especially on laptops you can only hope that the system builder didn't really change anything from the stock chips. Afair they have some freedoms here and there wich might turn out surprisingly during oss development and will need quirks.
