Formulas:
|
|
L1 ITLB misses = PAGE_WALKS_ITLB_COUNT
|
|
L1 ITLB miss rate = PAGE_WALKS_ITLB_COUNT / INSTR_RETIRED_ANY
|
|
L1 ITLB miss duration [Cyc] = PAGE_WALKS_ITLB_CYCLES / PAGE_WALKS_ITLB_COUNT

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.
