Once user mode queues are evicted, the eviction fence is signaled, allowing the migration of the BO to proceed. A delayed worker is scheduled to restore all the BOs belonging to the evicted process and restart its queues. During suspend/resume of the GPU we also evict all processes to allow KGD to save BOs in system memory, since VRAM will be lost. v2: * Account for eviction when updating of q->is_active in MQD manager Signed-off-by: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
