    Phoronix: Early Radeon DRM-Next Tests Ahead Of Linux 4.7, Mesa 11.3: Many Improvements, One Card Falls

    With the AMDGPU and Radeon changes all settled down for what's proposed for Linux 4.7, this weekend I'm benchmarking both of these open-source AMD Linux Direct Rendering Manager drivers. First up is the Radeon DRM driver with various OpenGL benchmarks in conjunction with Mesa 11.3-devel.

    The quality the open-source AMD drivers have reached is really impressive, especially considering the rough start GCN had on linux.
    Thanks and keep up the good work!

      Curious how it's like the 290 was dropped off a cliff...

          Can confirm that Infinite + Mesa + r600 doesn't work for me either. Still couldn't figure out which of these components has the issue. It worked with older Mesa versions and it still works with fglrx, but fglrx requires old kernel and old xorg, so it isn't a viable option these days.

              Why R9 290 drop so low? Michael can compare these with R9 285 and FGLRX?

                My suspicion with the r9 290 being low would be DPM not working as intended.

                  I agree with that, maybe 290 profiles are missing.

                  Michael do you have a log with gpu frenquecies/gpusage/powerconsumption? It should be ez to check if the card is not running at 3d frequencies.

                    R9 290 is most likely running at its lowest clocks. Michael could send us the output of:

                    Code:
                    sudo cat /sys/kernel/debug/dri/0/radeon_pm_info
                    if such a file is available on the benchmarking machine.
