Subject: [PATCH V3 0/9] perf: Intel uncore pmu counting support
Date: Wed, 2 May 2012 10:07:11 +0800 [thread overview]
Message-ID: <1335924440-11242-1-git-send-email-zheng.z.yan@intel.com> (raw)
Hi, all
Here is the V3 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_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
