Formulas:
L1 DTLB request rate = DATA_CACHE_ACCESSES / RETIRED_INSTRUCTIONS
L1 DTLB miss rate = (L2_DTLB_HIT_ALL+DTLB_MISS_ALL)/RETIRED_INSTRUCTIONS
L1 DTLB miss ratio = (L2_DTLB_HIT_ALL+DTLB_MISS_ALL)/DATA_CACHE_ACCESSES
L2 DTLB request rate = (L2_DTLB_HIT_ALL+DTLB_MISS_ALL)/RETIRED_INSTRUCTIONS
L2 DTLB miss rate = DTLB_MISS_ALL / RETIRED_INSTRUCTIONS
L2 DTLB miss ratio = DTLB_MISS_ALL / (L2_DTLB_HIT_ALL+DTLB_MISS_ALL)
-
L1 DTLB request  rate tells you how data intensive your code is
or how many data accesses you have on average per instruction.
The DTLB miss  rate gives a measure how often a TLB miss occurred
per instruction. And finally L1 DTLB  miss ratio tells you how many
of your memory references required caused a TLB miss on average.
NOTE: The L2 metrics are only relevant if L2 DTLB request rate is
equal to the L1 DTLB miss rate!
