|
Event Name | U..K | TH | Count |
CPU_CYCLES | x___ | 0 | 659001879 |
BACK_END_BUBBLE.ALL | x___ | 0 | 99866365 |
BE_EXE_BUBBLE.GRALL | x___ | 0 | 1244270 |
PLM: Privilege Level Mask
U/K = user/kernel levels (U: level 3, K: level 0)
The intermediate levels (1, 2) are unused on
x : the metric is measured at the given level (_ : not measured)
TH: event THreshold, determines the event counter behavior, TH == 0 : counter += event_count_in_cycle
TH > 0 : counter += (event_count_in_cycle >= threshold ? 1 : 0)
%of Cycles lost due to stalls (lower is better):
15.15= 100 * (BACK_END_BUBBLE.ALL / CPU_CYCLES)
%of Cycles stalled due to GR/GR or GR/load dependency (lower is better):
0.19= 100 * (BE_EXE_BUBBLE.GRALL / CPU_CYCLES)
