One set for 521 each instance of an L3 cache, another set for each processor 522 package. The L3 cache directories are named "mon_L3_00", 523 "mon_L3_01" etc. The package directories "mon_PERF_PKG_00", 524 "mon_PERF_PKG_01" etc. 525 > 526 Within each directory there is one file per event. For 527 example the L3 directories may contain "llc_occupancy", "mbm_total_bytes", 528 and "mbm_local_bytes". The PERF_PKG directories may contain "core_energy", 529 "activity", etc. The info/*/mon_features files provide the full 530 list of event/file names. 531 532 "core energy" reports a floating point number for the energy (in Joules) 533 consumed by cores (registers, arithmetic units, TLB and L1/L2 caches) 534 during execution of instructions summed across all logical CPUs on a 535 package for the current RMID. 536 537 "activity" also reports a floating point value (in Farads). 538 This provides an estimate of work done independent of the 539 frequency that the CPUs used for execution. 540 541 Note that these two counters only measure energy/activity 542 in the "core" of the CPU (arithmetic units, TLB, L1 and L2 543 caches, etc.). They do not include L3 cache, memory, I/O 544 devices etc. 545 546 All other events report decimal integer values. 547 548 In a MON group these files provide a read out of the current 549 value of the event for all tasks in the group. In CTRL_MON groups 550 these files provide the sum for all tasks in the CTRL_MON group 551 and all tasks in MON groups. Please see example section for more 552 details on usage. 553 554 On systems with Sub-NUMA Cluster (SNC) enabled there are extra 555 directories for each node (located within the "mon_L3_XX" directory 556 for the L3 cache they occupy). These are named "mon_sub_L3_YY" 557 where "YY" is the node number. 558 559 When the 'mbm_event' counter assignment mode is enabled, reading 560 an MBM event of a MON group returns 'Unassigned' if no hardware 561 counter is assigned to it. For CTRL_MON groups, 'Unassigned' is 562 returned if the MBM event does not have an assigned counter in the 563 CTRL_MON group nor in any of its associated MON groups. 564 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
