From: Yan, Zheng
Date: Sat Mar 31 2012 - 21:41:56 EST
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
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.
Changes since v1:
- Modify perf tool to parse events from sysfs
- A few minor code cleanup
