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. Signed-off-by:

The error handling is off by one. We should not free the first "tables[i].bo" without decrementing "i" because that might result in a double free. The second problem is that when an error occurs, then the zeroth element "tables[0].bo" isn't freed. I had make "i" signed int for the error handling to work, so I just updated "ret" as well as a clean up.
