hi,
adding --per-node option to aggregate stats per NUMA nodes,
you can get now use stat command like:
# 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
...
v2 changes:
- use mallox instead of zalloc plus adding comment [Arnaldo]
- rename --per-numa to --per-node [Alexey]
- rename function names to have node instead of numa
