There are 5 total that need this added - this one is the only one that fails from the pmctest.py script because it's the only one with bit 0 set (IAP_M_CORE) in its flags which causes a hard pmc_allocation failure. MEM_LOAD_UOPS_LLC_MISS_RETIRED.LOCAL_DRAM - this is due to adding this event to the SNB Xeon event list in the header file, but IAP_F_SBX is missing from the associated IAPDESCR for D3H_01H in hwpmc_core.c. It's not clear to me why you are seeing failures on those other events. Maybe make sure libpmc/pmcstat/pmccontrol/hwpmc are all in sync? Thanks for working on this!
