    Phoronix: Thermal Monitoring Comes To Newer Radeon DRM

    Over the past few days we have had a number of new open-source ATI Radeon support upbringings to report on including the ATI R600/700 Gallium3D driver being merged, voltage control for managing the power on newer ATI GPUs, and the ATI Radeon HD 5000 series Mesa code coming soon, but the slew of open-source ATI news is not over yet...

    How do I read the temp after applying the patch?

      Check your sysfs for a temperature readout.
      It will be some file on sysfs that you need to cat.

      Depending on how it is exposed, temperature monitor programs should be able to utilise it. Otherwise, they'll have to be updated.

        Make sure you are using v2 of the patch. It will show up as another hwmon device. See the /sys/class/hwmon. It should work with existing hwmon utilities.

            Cool it's working.

            Code:
            $ echo high > /sys/class/drm/card1/device/power_profile
            wait a little...
            $ cat /sys/class/hwmon/hwmon0/temp1_input
            65000
            
            $ echo low > /sys/class/drm/card1/device/power_profile
            wait a little...
            $ cat /sys/class/hwmon/hwmon0/temp1_input
            61000
            
            $ echo minimum > /sys/class/drm/card1/device/power_profile
            wait a little...
            $ cat /sys/class/hwmon/hwmon0/temp1_input
            47000
            Also shows up in GNOME Sensors Applet.

                There is many dev made around open-source ATI driver, but still no 3D acceleration. I can't wait playing my games with open-source stack and getting ride of fglrx.
                I'm no dev at all, but why is it so long to develop a 3D driver, knowing that ATI released the specs for doing it more than a year ago?

                  3d acceleration is missing only on Evergreen, and according to recent news, it's coming soon...
