Dears,
I am beginner of using opencsd-perf to study the coresight. My testing platform is Qcom smart phone (SDM845).
I've successful build the opencsed lib and perf-opencsd (both are master branch) https://github.com/Linaro/OpenCSD https://github.com/Linaro/perf-opencsd
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
