hi,
I want to use perf to profile how many events are emitted on vdso section?
I followed the document Documentation/trace/tracepoint-analysis.txt to do that:
$ perf record -e cycles -f ./hackbench 10
$ perf report
But I can't see any events emitted on vdso section. I used 2.6.34
kernel and x86_32 host.
What's wrong with that? Could anyone give me some clues how to get
events data on vdso section?
Thanks a lot!
