Wayland On Mesa Now Supports DRI_PRIME, Render Nodes
Written by Michael Larabel in Wayland on 11 May 2015 at 02:46 PM EDT. 9 Comments
Axel Davy has added support to Mesa's EGL code for supporting DRM Render-Nodes and with that supporting DRI_PRIME when using Wayland.

Render-nodes expose a GPU for off-screen rendering and GPGPU without needing display access. DRI_PRIME makes it possible to use an alternative GPU for rendering an application/game using the DRI_PRIME environment variable. DRI_PRIME is particularly useful for those with notebooks/ultrabooks sporting dual graphics processors.

Axel Davy added the EGL Wayland render-nodes and EGL Wayland DRI_PRIME support to mainline Mesa today along with a few other related commits. There's also now swrast support (Mesa software rasterizer) support too.

These new Mesa EGL features will be found with the upcoming Mesa 10.6 release due out in June.
