METRICS
Runtime (RDTSC) [s] time
Clock [MHz] 1.E-06*PMC1/time
CPI PMC1/PMC0
L1 DTLB load misses PMC2
L1 DTLB load miss rate PMC2/PMC0

Formulas:
L1 DTLB load misses = L1D_TLB_REFILL_RD
L1 DTLB load miss rate = L1D_TLB_REFILL_RD / INST_RETIRED
L1 DTLB store misses = L1D_TLB_REFILL_WR
L1 DTLB store miss rate = L1D_TLB_REFILL_WR / INST_RETIRED
-
The DTLB load and store miss rates gives a measure how often a TLB miss occurred
per instruction.
