L1I_READS Number of demand fetch reads to the L1
instruction cache (32-byte chunks). For more
information, see L1I_READS .
L2I_DEMAND_READS Number of instruction requests to L2 instruction
cache due to L1 instruction cache demand fetch
misses. This includes the number of demand
fetches that miss both the L1 instruction cache
and the ISB, regardless of whether they hit or
miss in the RAB.
L2I_PREFETCHES Number of prefetch requests issued to the L2
instruction cache. This includes streaming and
non-streaming prefetches.
L2I_READS.ALL.ALL Number of cacheable code reads handled by the
L2 instruction cache.
L2I_READS.MISS.ALL Number of demand fetch and prefetch misses in
cacheable code reads handled by the L2
instruction cache. This only includes the primary
misses.
L2I_READS.MISS.DMND Number of demand fetch misses in cacheable
code reads handled by the L2 instruction cache.
This includes the primary misses.

% of Cycles lost due to Front end
stalls (ICACHE, ITLB and branch
execution)
Percentage of cycles lost due to instruction cache,
instruction translation lookaside buffer, and
branch execution stalls.
