PAPI counts events per device (which can be iMC, caching and home agent(cha)). These are counted as separate events such as skx_unc_imc0::UNC_M_RPQ_OCCUPANCY for iMC 0. Is there a way to measure this for all the iMCs at the same time? The Linux perf tool can do this, an equivalent event is unc_m_rpq_occupancy, but this cannot be measured from PAPI.
How to aggregate PAPI uncore events such as skx_unc_imc0 to measure for all devices?
