Synchronized GPU priority scheduling

Since the early days, Unix-like systems have implemented the concept of process priorities, where higher-priority processes are given more CPU time to get their work done. Implementations have changed, and alternatives (such as deadline scheduling) are available for specialized situations, but the core priority (or, in an inverted sense, "niceness") concept remains essentially the same. What should happen, though, in a world where increasing amounts of computing work is done outside of the CPU? Tvrtko Ursulin has put together a patch set showing how the nice mechanism can be extended to GPUs as well.
