For AMD compute (amdkfd) driver. All AMD compute devices are exported via single device node /dev/kfd. As a result devices cannot be controlled individually using device cgroup. AMD compute devices will rely on its graphics counterpart that exposes /dev/dri/renderN node for each device. For each task (based on its cgroup), KFD driver will check if /dev/dri/renderN node is accessible before exposing it.
