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.
By default, the firmware does not print trace messages. Please contact your FAE for more details on
how to enable firmware tracing.
mstfwtrace Usage
Enter the following command:
# mstfwtrace [options...]
where
-h|--help Print this help message and exit
-d|--device PCI device (BDF)
--tracer_mode Tracer mode [MEM]
--real_ts Print real timestamps in [hh:mm:ss:nsec] format
-i|--irisc iRISC name (use the "all" option after -i)
-s|--stream Run in streaming mode
-m|--mask Trace class mask, use "+" to enable multiple classes or use
integer format, e.g: -m class1+class2+... or 0xff00ff00
-l|--level Trace level
-v|--version Print tool's version and exit
--ignore_old_events Ignore collecting old events
Device-Specific Information:
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.
