Intel Arc Graphics customers have been eager to see the new Xe DRM kernel driver merged as a modern alternative to the long-standing i915 Direct Rendering Manager driver. The Xe driver should allow for better performance, is focused just on recent Intel graphics hardware, makes use of modern kernel features, and will allow for new features such as around the Vulkan sparse support. One of the blockers for getting the Xe driver merged at least in experimental form is getting the necessary DRM scheduler changes merged...

A decade ago the Radeon R600g SB shader back-end proved useful for boosting gaming performance on pre-GCN graphics cards of the time and proved useful. But in more recent years in the R600g switch to NIR, the SB path hasn't received much attention and its benefits have diminished. The R600g SB code has now been dropped...
