    As I mentioned before you can adjust the amount via other xrandr properties:
    xrandr --output HDMI-0 --set "underscan vborder" 5
    xrandr --output HDMI-0 --set "underscan hborder" 5
    adjust the values...

    Mesa only supports GL 3.3 in core profiles. You need to request a core profile to to get GL versions larger than 3.0.

    I changed it to 4.x since newer versions of GL 4 kept getting released that the hardware supports.

    CI parts use a different BAR for MMIO. Older versions of the tool were not aware of that. I've been meaning to add a debugfs or ioctl interface to query these registers so you won't have to add as...

    From a hardware perspective, it's the same. You are just mapping system pages into the GPU GART aperture. The only difference is who allocated the memory. With the userptr interface, you are...

    The openmax state tracker in mesa supports both decode and encode on radeon hw.

    The userptr ioctls in both the radeon and intel kernel drivers just allow you to request user pages be pinned temporarily for DMA. HSA allows the GPU to access unpinned pages directly without the...

    The problem is certain parts of the decode pipeline are not well suited to parallel shader type operations. As such you can only accelerate certain parts of the pipeline effectively on shaders.

    You should be able to use the --pos xxy option with any randr capable driver to specify the x,y location of the display. See the xrandr man page.

    For the most part it does, but there are not many users using non-x86 platforms so they rarely get tested. Also older hw doesn't get tested very often either. E.g., the radeon 9200 is like 12 years...

    There is no support for crossfire in the open source driver at the moment. If someone wanted to work on it, there is no special hardware required. It's just lots of work in mesa to split up...
