Thanks for testing! Yes you can test it quickly using top mode for example: kldload hwpmc pmccontrol -L to list all events some test: - offcore pmcstat -SOFF_CORE_RESPONSE_0,rsp=3DREQ_DMND_DATA_RD+RES_ANY -w1 -T - unhalted cycle (programmable counter) pmcstat -n2000000 -SCPU_CLK_UNHALTED.THREAD_P -w4 -T - INSTR_RETIRED_ANY (fixed counter) pmcstat -n2000000 -S INSTR_RETIRED_ANY -w4 -T - Soft counter: pmcstat -SPAGE_FAULT.ALL -w4 -T all at the same time (and change view by pressing 'p': pmcstat -SOFF_CORE_RESPONSE_0,rsp=3DREQ_DMND_DATA_RD+RES_ANY -n2000000 = -SCPU_CLK_UNHALTED.THREAD_P -n2000000 -S INSTR_RETIRED_ANY = -SPAGE_FAULT.ALL -w1 -T all events are described in the man page pmc.ivybridge >=20 > regards, > Bapt --Apple-Mail=_78EA6D67-D133-4FFF-B040-990090390179--
