drm/amdkfd: Check against device cgroup 2019-10-07T20:11:38+00:00 Harish Kasiviswanathan Harish.Kasiviswanathan@amd.com 2018-08-20T16:14:50+00:00 6b855f7b83d2fb0237263f143437aedf8caed152 Participate in device cgroup. All kfd devices are exposed via /dev/kfd. So use /dev/dri/renderN node. Before exposing the device to a task check if it has permission to access it. If the task (based on its cgroup) can access /dev/dri/renderN then expose the device via kfd node. If the task cannot access /dev/dri/renderN then process device data (pdd) is not created. This will ensure that task cannot use the device. In sysfs topology, all device nodes are visible irrespective of the task cgroup. The sysfs node directories are created at driver load time and cannot be changed dynamically. However, access to information inside nodes is controlled based on the task's cgroup permissions.
