Abstract
This talk will be about the principles of GPU offloading, how it is handled with X DRI2, and how we decided to handle it on Wayland. It's been about 3-4 years since first experiments on GPU offloading on X were done. How is GPU offloading handled with X ? And how the different design of Wayland could influence the way it's handled ? In this talk, I'll present: * the technical difficulties involved in GPU offloading. * how X DRI2 handles GPU offloading. * What choices we made when designing Wayland GPU offloading support. * The work that has been done, and what is remaining to do for a better user experience.
