Subject: [PATCH 38/63] perf stat: Add --per-node agregation support
Date: Thu, 7 Nov 2019 15:59:46 -0300 [thread overview]
Message-ID: <20191107190011.23924-39-acme@kernel.org> (raw)
In-Reply-To: <20191107190011.23924-1-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
Adding new --per-node option to aggregate counts per NUMA
nodes for system-wide mode measurements.
You can specify --per-node in live mode:
# perf stat -a -I 1000 -e cycles --per-node
# time node cpus counts unit events
1.000542550 N0 20 6,202,097 cycles
1.000542550 N1 20 639,559 cycles
2.002040063 N0 20 7,412,495 cycles
2.002040063 N1 20 2,185,577 cycles
3.003451699 N0 20 6,508,917 cycles
3.003451699 N1 20 765,607 cycles
...
Or in the record/report stat session:
# perf stat record -a -I 1000 -e cycles
# time counts unit events
1.000536937 10,008,468 cycles
2.002090152 9,578,539 cycles
3.003625233 7,647,869 cycles
4.005135036 7,032,086 cycles
^C 4.340902364 3,923,893 cycles
# perf stat report --per-node
# time node cpus counts unit events
