Description

Current Linux display server architecture is based on the assumption that memory access by direct rendering devices is implicitly synchronized by the kernel. There is a growing consensus in the community that this has inherent limitations for both performance and functionality. This talk will discuss current efforts towards moving to an explicit synchronization model across Wayland [1], X11 / Xwayland [2], and user-space graphics drivers, including some of the challenges posed, potential solutions, and expected benefits to the Linux graphics ecosystem.
