amdgpu libraries that use dmabuf fd to share GPU memory between processes close the dmabuf fds immediately after using them. However, it is possible that checkpoint of a process catches one of the dmabuf fds open. In that case, the amdgpu plugin needs to handle it. The checkpoint of the dmabuf fd does require the device file it was exported from to have already been dumped To identify which device this dmabuf fd was exprted from, attempt to import it on each device, then record the dmabuf handle it imports as. This handle can be used to restore it. Signed-off-by: David Francis <David.Francis@amd.com>
