of cycles lost (stall cycles) due to FR/FR or
FR/load dependency.
BE_EXE_BUBBLE.GRALL Full Pipe Bubbles in Main Pipe due to GR/GR or
GR/load dependency stalls. This is the number
of cycles lost (stall cycles) due to GR/GR or
GR/load dependency.
BE_EXE_BUBBLE.GRGR Full Pipe Bubbles in Main Pipe due to GR/GR
dependency stalls. This is the number of cycles
lost (stall cycles) due to GR/GR dependency.
CPU_OP_CYCLES.ALL Number of elapsed CPU operating cycles.
DATA_REFERENCES The number of data memory references issued
into memory pipeline. Includes check loads,
non-uncacheable accesses, RSE operations,
semaphores, and floating-point memory
references. The count includes wrong path
operations but excludes predicated off
operations. This event does not include VHPT
memory references.
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.
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.
L1D_READ_MISSES.ALL Number of L1 data cache read misses. L1 data
cache is write through; therefore, write misses
are not counted. The count only includes misses
caused by references counted by an L1D_READS
event. It will include L1 data cache misses which
missed the ALAT, but not those which hit in the
ALAT. Semaphores are not handled by the L1
data cache and are not included in this count.
L2D_INSERT_MISSES Number of times a cacheable data request missed
in the L2D cache on its first lookup. This does
