Hi, all
Here is the RFC patches to add uncore counting support for Nehalem, Sandy Bridge and Sandy Bridge-EP, applied on top of current tip. 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_xxx/events/
You can use 'perf stat' to access to the uncore pmu. For example: perf stat -a -C 0 -e 'uncore_nhm/QMC_WRITES_FULL_ANY/' sleep 1
Any comment is appreciated. Thank you
--- Changes since v1: - Modify perf tool to parse events from sysfs - A few minor code cleanup
