    Default Linux 3.12 To Support AMD "Berlin" HSA APU

    Phoronix: Linux 3.12 To Support AMD "Berlin" HSA APU

    The Linux 3.11 kernel hasn't even been released yet but the Radeon DRM driver changes for the Linux 3.12 kernel are already lined up and waiting to be pulled into the drm-next tree...

    Can anyone from AMD comment on whether DPM will be enabled by default in 3.12 or not? Also, will we see CIK support in Mesa/X by the time the hardware is released (supposedly October).

    GPU Run-Time Power Management has also been merged into the DRM-Next tree for Linux 3.12. This code allows for powering down secondary GPUs such as those in Optimus laptop configurations. GPUs controlled by DRM drivers can now be dynamically toggled on and off depending upon whether they're needed.
    I imagine this coupled with the DPM in 3.11 would make hybrid graphics perfect. I'm assuming you mean an intel iGPU and AMD discrete GPU.

    Personally my a10-4600m + 7670m is messed up when using DPM I hope this get's fixed with 3.12.
