hi, Joe asked for possibility to add user defined metrics. Given that we already have metrics support, I added --metric option that allows to specify metric on the command line, like:
# perf stat --metric 'DECODED_ICACHE_UOPS% = 100 * (idq.dsb_uops / \ (idq.ms_uops + idq.mite_uops + idq.dsb_uops + lsd.uops))' ...
The code facilitates the current metric code, and I was surprised how easy it was, so I'm not sure I omitted something ;-)
