The code is based on Lin Ming's old patches. For Nehalem and Sandy Bridge-EP, A few general events are exported under sysfs directory: /sys/bus/event_source/devices/${uncore_dev}/events/ Each file in the events directory defines an event. The content is a string such as: config=1,config1=2 You can use 'perf stat' to access to the uncore pmu. For example: perf stat -a -C 0 -e 'Uncore_iMC_0/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 Changes since v3: - Use per cpu pointer to track uncore box - Rework the cpu hotplug code because topology_physical_package_id() return wrong result when the cpu is offline - Rework the event alias code, event terms are stored in the alias structure instead events string
