    Default Provider Object Support For RandR 1.5

    Phoronix: Provider Object Support For RandR 1.5

    The latest work by David Airlie for improving the X.Org infrastructure to handle modern GPU features (e.g. multi-GPUs, Optimus-like capabilities, etc) comes in the form of a proposed RandR protocol update...

    How about configuring outputs on a single GPU, so it can be used on multi-seat setup? I skimmed through the patch, but didn't saw such configuration options.

    I believe that should already be possible

    Got nothing to do with randr since randr runs inside an X server, and a X server is used by one user. multi-seat needs an X server per-user, so needs kernel changes, and no changes to randr at all.

    Please allow an amateurish question:

    Is this in any way connected to a noticeable performance penalty?
    Shoveling the framebuffer to another GPU doesn't sound like a terrible task.
    1280x1024@32bit@60Hz (raw) should be 300 MB/s if my quick calculation
    doesn't fail. But maybe there's more to it.
