    Phoronix: Google's Pixel C Android Tablet Uses The Nouveau Kernel Driver

    It turns out that with Google's Pixel C Android tablet, they decided to use the open-source Nouveau DRM kernel driver by default for this ARM device powered by NVIDIA's Tegra X1 SoC...

    Great news, maybe this is why the graphic performance is not great compared to the TK1, but all in all the best news for the open source graphic drivers.

      The DRM layer is usually very tiny, so I doubt this will affect the performance a lot. But it allows the blob to use GPL-only linux features like DMA-BUF + GEM. Both are required for a good memory management on the X1, especially for managing the shared memory. The good news here is, NVIDIA must also release all in-kernel parts of their patches. Will the power management parts of it matches well to desktop?

        Of course no.

          Can you please elaborate what leads you to this conclusion?

            It is great to see Google uses open-source alternatives. Kudos!

              Damn, I was just walking out of the airport for my summer vacation in Hell and I caught an instant cold! It's ******* freezing down here!

              On a more serious note thought, it seems nVidia got their single open-source kernel driver that can serve both Mesa and their proprietary user-space OpenGL implementation out of the door in a released, working product before AMD could bring AMDGPU to the masses! I am surprised.

                Because who cares about AMD , seriously?

                  Why the surprise ? The two projects started at roughly the same time; we have been prioritizing the upstream open source stack while NVidia has been prioritizing the mostly-closed-source stack (at the expense of not having it all upstream yet). I would have been surprised if their hybrid stack had *not* come out first.

                    Not OP, but Nvidia doesn't have the best reputation for cooperation. I'm not expecting something akin to AMDGPU out of them either.
                    All opinions are my own not those of my employer if you know who they are.
