L1 ITLB misses = ITLB_MISSES_CAUSES_A_WALK
|
||
|
|
L1 ITLB miss rate = ITLB_MISSES_CAUSES_A_WALK / INSTR_RETIRED_ANY
|
||
|
|
L1 ITLB miss duration [Cyc] = ITLB_MISSES_WALK_ACTIVE / ITLB_MISSES_CAUSES_A_WALK

The ITLB miss rates gives a measure how often a TLB miss occurred
|
||
|
|
per instruction. The duration measures the time in cycles how long a walk did take.
