Subject: [PATCH v6 11/11] perf/tools/pmu-events/powerpc: Add hv_24x7 socket/chip level metric events
Date: Fri, 20 Mar 2020 18:24:06 +0530 [thread overview]
Message-ID: <20200320125406.30995-12-kjain@linux.ibm.com> (raw)
In-Reply-To: <20200320125406.30995-1-kjain@linux.ibm.com>
The hv_24×7 feature in IBM® POWER9™ processor-based servers provide the
facility to continuously collect large numbers of hardware performance
metrics efficiently and accurately.
This patch adds hv_24x7 metric file for different Socket/chip
resources.
Result:
power9 platform:
command:# ./perf stat --metric-only -M Memory_RD_BW_Chip -C 0 -I 1000
1.000096188 0.9 0.3
2.000285720 0.5 0.1
3.000424990 0.4 0.1
command:# ./perf stat --metric-only -M PowerBUS_Frequency -C 0 -I 1000
1.000097981 2.3 2.3
2.000291713 2.3 2.3
3.000421719 2.3 2.3
4.000550912 2.3 2.3
