Dear Performance Tuning Experts,
Is it possible tocollect sampling data for uncore performance events using PTU, such as, for example, UNC_QMC_NORMAL_READS.CH0 ?
If the answer it yes, how would one go about it in the PTU framework?
As far as I understand, PTU has the ability to count some uncore events using OFFCORE_RESPONSE_0.REQUEST.RESPONSE counter with appropriate REQUEST.RESPONSE encoding, but a lot of uncore counters do not fall into that category.
Thanks very much,
