hi, Joe asked for possibility to add user defined metrics. Given that we already have metrics support, I added --metrics-file option that allows to specify custom metrics.
$ cat metrics # IPC mine1 = instructions / cycles; /* DECODED_ICACHE_UOPS% */ mine2 = 100 * (idq.dsb_uops / \ (idq.ms_uops + idq.mite_uops + idq.dsb_uops + lsd.uops));
$ sudo perf stat --metrics-file ./metrics -M mine1,mine2 --metric-only -a -I 1000 # time insn per cycle mine1 mine2 1.000536263 0.71 0.7 41.4 2.002069025 0.31 0.3 14.1 3.003427684 0.27 0.3 14.8 4.004807132 0.25 0.2 12.1 ...
v2 changes: - add new --metrics-file option - rebased on current perf/core expression bison/flex enhancements

thanks, jirka
