Weston DRM Compositor Support Proposed For NVIDIA's TK1

[rxonda]

From having had a look at the patches, it seems they slightly modify the Weston DRM/KMS backend to support the mentioned device, which has to be handled in a different way than usual GPUs. I'm also not sure here, but I remember hearing that, while the GPU was under Nouveau territory, the display had to be handled with a different DRM driver - the Tegra. That may be the reason.

As for the NVIDIA question, I believe not. NVIDIA's official driver does not use DRM nor KMS. Another backend for Weston would have to be developed to support whatever-NVIDIA-uses.

thanks for the answer Kalrish.
I googled for linux graphics stack and found out that NVidia cant implement a libdrm, unless they open sourced their code.

I dont quite get it...
Codethink rewrite Weston compositor, but instead of accessing KMS, it access DRM infrastructure?
Whats that mean? Means that NVidia also can support Wayland in the same manner?
Please, excuse my ignorance if Im saying too much non senses.

Does it all mean that we should expect tablets with TK1 and native Wayland running Plasma Active, Nemo, Sailfish and etc.?

Phoronix: Weston DRM Compositor Support Proposed For NVIDIA's TK1

Support for running Wayland's Weston compositor directly off the DRM kernel driver for the NVIDIA Tegra K1 SoC found within the Jetson TK1 development board has been proposed for mainline Weston...
