Hello all,
I am having trouble tracing child threads when using address filtering
with intel_pt ..
Assume this test code:
thread_start(){
...
test();
...
}
test(){
printf("test");
}
main(){
...
pthread_create(......, thread_start,....);
}
Tracing the above program with the following command:
perf record -v -m 512,10000 -e intel_pt//u -T --switch-events --filter
'filter * @ ./test' -- ./test
Returns zero trace for code executed by child thread, i.e.
thread_start() and test() functions..
While tracing without the filter does include the threads trace:
perf record -v -m 512,10000 -e intel_pt//u -T --switch-events -- ./test
Is this intended? or is it a bug?
Thanks!
Mansour.
