SRIOV is kinda by design vendor specific. You set up the VF endpoint, it shows up, it's all hw+fw magic. Nothing for cgroups to manage here at all.
Right, so in theory you just use the device cgroup with the VF endpoints.
All I meant is that for the container/cgroups world starting out with time-sharing feels like the best fit, least because your SRIOV designers also seem to think that's the best first cut for cloud-y computing. Whether it's virtualized or containerized is a distinction that's getting ever more blurry, with virtualization become a lot more dynamic and container runtimes als possibly using hw virtualization underneath.
I disagree. By the same logic, the existence of CU mask would imply it being the preferred way for sub-device control per process.
