The code is based on Lin Ming's old patches. For Nehalem and Sandy Bridge-EP, A few general events are exported under directory: /sys/bus/event_source/devices/${uncore_dev}/events/ Each file in the events directory defines an event. The content is like: config=1,config1=2 You can use 'perf stat' to access to the uncore pmu. For example: perf stat -a -C 0 -e 'uncore_imc0/CAS_COUNT_RD/' sleep 1 Any comment is appreciated. Thank you --- Changes since v1: - Modify perf tool to parse events from sysfs - A few minor code cleanup Changes since v2: - Place all events for a particular socket onto a single cpu - Make the events parser in perf tool reentrantable - A few code cleanup
