Hi, Looks like ocount can not collect the performance events of PM_L2_LD_MISS on my power8 machine. The information and command is: *cye@...$ ocount-1.2 -e PM_L2_LD_MISS ls* *perf_event_open failed with Invalid argument* *Caught runtime error while setting up counters* *Internal Error. Perf event setup failed.* *Error running ocount* Actually I found all of the events of PM_L2_XXXX does not work. Does this happens to anyone else? Here are some information might useful: *ocount-1.2 --version* *ocount-1.2: oprofile 1.2.0git compiled on Nov 5 2015 15:00:21* *uname -a* *Linux node-ibm-822 3.19.0-15-generic #15-Ubuntu SMP Thu Apr 16 23:32:13 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux* Regards, Chencheng Ye -- Chencheng Ye Cluster and Grid Computing Lab (CGCL) Services Computing Technology and System Lab (SCTS) School of Computer Science and Technology (CS) Huazhong University of Science and Technology (HUST) Wuhan, 430074, China ------------------------------------------------------------------------------ _______________________________________________ oprofile-list mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/oprofile-list
