The metrics are:
• Total - Misses Per Second
This is the total number of L2 instruction cache misses per second. It includes all
instruction prefetch misses and instruction demand fetch misses.
• Pfetch - Misses Per Second
This is the number of instruction line prefetch requests (streaming and
non-streaming) that miss the L2 instruction cache per second.
• Dfetch - Misses Per Second
This is the number of instruction line demand requests that miss the L2 instruction
cache per second.
• Total - Misses Per Kinst
This is the total number of L2 instruction cache misses per 1000 retired instructions,
including nops and predicated off instructions. It includes instruction prefetch
misses and instruction demand fetch misses.
• Pfetch - Misses Per Kinst
This is the number of instruction line prefetch requests (streaming and
non-streaming) that miss the L2 instruction cache per 1000 retired instructions,
including nops and predicated off instructions.
• Dfetch - Misses Per Kinst
This is the number of instruction demand requests that miss the L2 instruction
cache per 1000 retired instructions, including nops and predicated off instructions.
• Instr Per Access
This is the ratio of the total number of instructions retired per L2 instruction cache
access, including nops and predicated off instructions. The L2 instruction cache
accesses include demand fetches and prefetches that miss the L1 instruction cache.
• %Miss - Total
This is the percentage of all the L2 instruction cache misses out of the total number
of L2 instruction cache accesses. Accesses include instruction fetches/prefetches
that miss the L1 instruction.
• %Miss - Pfetch
This is the percentage of all the L2 instruction prefetch misses out of the total
number of L2 instruction prefetch accesses.
• %Miss - Dfetch
This is the percentage of all the L2 instruction demand fetch misses out of the total
number of L2 instruction demand fetch accesses.
