Subject: [PATCH] tracepoint: Print the function symbol when tracepoint_debug is set
Date: Tue, 4 Mar 2025 18:18:43 +0800 [thread overview]
Message-ID: <20250304101843.12562-1-shijie@os.amperecomputing.com> (raw)
When tracepoint_debug is set, we may get the output in kernel log:
[ 380.013843] Probe 0 : 00000000f0d68cda
It is not readable, so change to print the function symbol.
After this patch, the output may becomes:
[ 54.930567] Probe 0 : perf_trace_sched_wakeup_template
