PLM
Event Name U..K TH Count
-----------------------------------------------
CPU_CYCLES x___ 0 659001879

PLM: Privilege Level Mask
U/K = user/kernel levels (U: level 3, K: level 0)
The intermediate levels (1, 2) are unused on HP-UX or Linux
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)
