Wayland Gets Improvements Inside Of Mesa
On Wednesday there was some Git activity surrounding the EGL/Wayland support inside Mesa.
Of the recent Mesa Git activity that impacts Wayland, this commit is arguably the most interesting. This latest work adds an EGL WL_create_wayland_buffer_from_image extension useful for nested Wayland compositors.
The commit description reads, "The function creates a wl_buffer which shares its contents with the given EGLImage. The expected use case for this is in a nested Wayland compositor which is using subsurfaces to present buffers from its clients. Using this extension it can attach the client buffers directly to the subsurface without having to blit the contents into an intermediate buffer. The compositing can then be done in the parent compositor."
Other work today includes enabling of throttling in SwapBuffers and other EGL/Wayland alterations.
