mstfwtrace Utility
The mstfwtrace utility extracts and prints trace messages generated by the firmware running on 5th
generation (Group II) devices iRISCs.
These trace messages inform developers of software drivers about internal status, events, critical
errors, etc. Trace messages generated by iRISCs are stored in the trace buffer. The trace buffer is
located in host memory.
When using secure firmware, the user needs to validate that the value "1" is set to /sys/kernel/
debug/tracing/events/mlx5/fw_tracer/enable.
By default, the firmware does not print trace messages. Please contact your FAE for more details on
how to enable firmware tracing.
