Abstract:
A data processing apparatus has processing circuitry for executing program instructions and trace circuitry for generating trace data indicating processing activities of the processing circuitry. The trace circuitry may detect a lockup state of the processing circuitry in which the processing circuitry does not make forward progress of execution of the program instructions. In response to detecting the lockup state, the trace circuitry may include in the trace data a lockup identifier indicating that the lockup state has occurred.
