Formulas:
L1 DTLB load misses = DTLB_LOAD_MISSES_ANY
L1 DTLB load miss rate = DTLB_LOAD_MISSES_ANY / INSTR_RETIRED_ANY
L1 DTLB load miss duration [Cyc] = DTLB_LOAD_MISSES_WALK_CYCLES / DTLB_LOAD_MISSES_ANY
L1 DTLB store misses = DTLB_MISSES_ANY-DTLB_LOAD_MISSES_ANY
L1 DTLB store miss rate = (DTLB_MISSES_ANY-DTLB_LOAD_MISSES_ANY) / INSTR_RETIRED_ANY
L1 DTLB store miss duration [Cyc] = (DTLB_MISSES_WALK_CYCLES-DTLB_LOAD_MISSES_WALK_CYCLES) / (DTLB_MISSES_ANY-DTLB_LOAD_MISSES_ANY)

The DTLB miss rate gives a measure how often a TLB miss occurred
per instruction. The store miss calculations are done using ALL-LOADS TLB walks.
