TODO: 1:when a job is considered as guilty, we should mark some flag in its fence status flag, and let UMD side aware that this fence signaling is not due to job complete but job hang. 2:if gpu reset cause all video memory lost, we need introduce a new policy to implement TDR, like drop all jobs not yet signaled, and all IOCTL on this device will return ERROR DEVICE_LOST. this will be implemented later.
