Subject: [RFC PATCH V2 0/6] perf: Intel uncore pmu counting support
Newsgroups: gmane.linux.kernel
Date: Sunday 1st April 2012 01:41:29 UTC (over 4 years ago)
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
