BACK_END_BUBBLE.FE Full pipe bubbles in main pipe due to front end.
This is the number of cycles lost (stall cycles) due
to instruction cache, ITLB, and branch execution
stalls.
BE_EXE_BUBBLE.ALL Full pipe bubbles in main pipe due to execution
unit stalls. This is the number of cycles lost (stall
cycles) due to stalls caused by the execution unit.
BE_EXE_BUBBLE.FRALL Full Pipe Bubbles in Main Pipe due to FR/FR or
FR/load dependency stalls. This is the number
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 general
register/general register or general register/load
dependency stalls. This is the number of cycles
lost (stall cycles) due to general register/general
register or general register/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
stalls.
BE_FLUSH_BUBBLE.ALL Full Pipe Bubbles in Main Pipe due to pipeline
flushes. This is the number of cycles lost (stall
cycles) due to branch misprediction or
exception/interruption flush.
BE_L1D_FPU_BUBBLE.ALL
BE_L1D_FPU_BUBBLE.L1D Full Pipe Bubbles in Main Pipe due to L1D cache.
This is the number of cycles lost (stall cycles) due
to L1D cache and L1/L2 DTLB.
BE_RSE_BUBBLE.ALL Full Pipe Bubbles in Main Pipe due to RSE stalls.
Percentage of cycles lost due to stalls in RSE
spilling/filling registers to/from memory.
CPU_OP_CYCLES.ALL Number of elapsed CPU operating cycles. (Note:
This event is called CPU_CYCLES on Itanium 2
systems.)
When HyperThreading is on, this is the number
of elapsed CPU operating cycles used by only
this process's hyperthread.
CPU_OP_CYCLES.ALL:all_threads=true Number of elapsed CPU operating cycles used
by both hyperthreads. Available only when
HyperThreading is on.
% Unstalled execution (higher is
better)
Percentage of unstalled cycles with respect to
total number of elapsed CPU operating cycles.
