[jolsa@krava perf]$ sudo ./perf stat -e cycles,instructions -a -x,
160517940,,cycles,2357448795,100.00,,Ghz,2357448795,100.00
^^^^^^^^^^^^^^^^^ what's this data?
84822675,,instructions,2357537479,100.00,0.53,insn per cycle
,,,2357537479,100.00,,stalled cycles per insn,2357537479,100.00
this line is probably wrong, as noted in previous email..?
thanks,
