[RESEND PATCH v1 09/11] perf: hisi: Miscellanous node(MN) event counting in perf
Anurup M
anurupvasu at gmail.com
Wed Nov 2 22:42:05 PDT 2016
From: Shaokun Zhang <zhangshaokun at hisilicon.com>
1. Add support to count MN hardware events.
2. Mn events are listed in sysfs at /sys/devices/hisi_mn2/events/
The events can be selected as shown in perf list
e.g.: For MN_READ_REQUEST event for Super CPU cluster 2 the
event format is
-e "hisi_mn2/read_req/"
