After reading [1], I tried "perf stat -a -e "uncore_imc_0/event=0xff,umask=0x00/" /bin/ls", it says "invalid or unsupported event". The machine is Intel Ivy Bridge i5-3320M with ArchLinux 3.11.2-1-ARCH. 'perf --version' is 'perf version 3.11.0' In '/sys/bus/event_source/devices/uncore_cbox_0/events', there is only one event 'clockticks'. Did I miss something? thanks, yuanfang [1] http://web.eece.maine.edu/~vweaver/projects/perf_events/faq.html#q1c -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
