Separate patch series sent out on Wednesday by Intel and AMD Linux developers are continuing work on prepping cgroup infrastructure support around graphics processors.
For a long time now there have been patches floating around for prepping Cgroup infrastructure around DRM drivers / graphics processors. This work would make it possible to monitor and limit GPU resources just as you can use cgroups for such on CPUs. This work could also be used for restricting video memory to a set of processes, among other possible restrictions.
