We are using libpfm4 to profile our SPR machines. The events prefixed by UNC_CHA_TOR_INSERTS and defined under spr_unc_cha_tor_inserts in file lib/events/intel_spr_unc_cha_events.h are always zeros. We suspect this to be a bug. By inspecting libpfm4 code, it might be a misuse of Extended Umask for these events. Please help us check it out!
