    Why? Am I missing something, or isn't PRIME supposed to be used for switchable graphics?

    Oh, and

    ...NVIDIA's new fast and amazing Tegra K1 SoC...
    which is nowhere to be seen and won't be for some time. I understand, this is just out of the need to kiss ass in order to keep receiving shiny new hardware.

    It's for sharing buffers between drivers using dma_buf. Prime is just the drm interface for this. It could be between a gpu and a webcam, or two gpus, or a gpu and a usb display adapter, a webcam and a video encoder, etc. Switchable graphics are just one of the use cases.

    that makes no sense. then he would also kiss ass AMD to get hardware again. and definitely does not do that...

    Surely the Tegra K1 would be supported by nouveau since it has a Kepler GPU.

    So it's basically Kama Sutra for Linux graphics.
