Add more trace coverage to amdxdna job handling and mailbox receive processing to make driver execution easier to debug. Extend the xdna_job trace event to record the command opcode in addition to the job sequence number. Use the enhanced tracepoint in the job run, sent-to-device, signaled-fence, and job-free paths so that trace output can be correlated with the command being executed. Also add debug-point tracing when a command is received through the submit ioctl path, and add a trace event when the mailbox RX worker runs. These changes improve visibility into job lifetime transitions and mailbox activity, which helps debug command flow and scheduler issues.
