DTLB_INSERTS_HPW Number of virtual hash page table entries
inserted into the DTLB by the hardware page
walker (HPW).
IA64_INST_RETIRED Number of retired IA-64 instructions. The count
includes predicated on and predicated off
instructions and nops, but excludes
hardware-inserted RSE operations.
L1DTLB_TRANSFER Number of times an L1 DTLB miss hits in the L2
DTLB for an access counted in L1D_READS.
L1D_READS The number of data memory read references
issued into memory pipeline that are serviced by
the L1 data cache (only integer loads), RSE loads,
L1-hinted loads (the L1 data cache returns data
if it hits in the L1 data cache but does not do a
fill), and check loads (ld.c). Non-cacheable
reads, VHPT loads, semaphores, floating-point
loads, and lfetch instructions are not counted
here because the L1 data cache does not handle
these. The count includes wrong path operations
but excludes predicated off operations.
L2DTLB_MISSES The number of L2 DTLB misses (which is the
same as references to HPW, DT LB_HIT=0) for
demand requests.
% of Cycles lost due to all stalls
(lower is better)
Percentage of cycles lost due to all stalls.
% of Cycles lost due to GR/load
dependency stalls (lower is better)
Percentage of cycles lost due GR/load
dependency stalls.
% of Cycles lost due to GR/GR
dependency stalls (lower is better)
Percentage of cycles lost due GR/GR dependency
stalls.
% of Cycles lost due to FR/load and
FR/FR dependency stalls (lower is
better)
Percentage of cycles lost due to FR/load and
FR/FR dependency stalls
Total L1 data TLB references Number of L1 data TLB references.
L1 data TLB for L1D miss
percentage
Percentage of L1 DTLB accesses that are misses.
L2 data TLB misses Number of L2 data TLB misses.
L2 data TLB miss percentage Percentage of L2 DTLB accesses that are misses.
Percentage of L2 DTLB misses
covered by the HPW
Percentage of L2 DTLB misses that were serviced
by the hardware page walker (HPW).
Percentage of data references
covered by L1 and L2 DTLB
Percentage of data references that was satisfied
in L1 DTLB or L2 DTLB.
