Dears,
I am beginner of using opencsd-perf to study the coresight.
My testing platform is Qcom smart phone (SDM845).
I can find some devices name like these, (
when executing `ls /sys/bus/coresight/devices/`)
..., coresight-stm, coresight-tmc-etf, coresight-tmc-etr, coresight-ssc-etm0, ...
However, when I using the commands, I got the error.
1. perfcsd record -e cs_etm/coresight-tmc-etf/ --per-thread ls
==> event syntax error: 'cs_etm/coresight-tmc-etf/' \___ unknown term
2. perfcsd record -e cs_etm/@coresight-tmc-etf/ --per-thread ls
==> event syntax error: 'cs_etm/coresight-tmc-etf/' \___ parser error
I've tried any solutions as many as possible, but I still cannot solve this problem.
Does perf-opencsd support the android?
Can you help me?
Thank you very much.
Eric
