Formulas:
|
|
Used cycles ratio [%] = 100*UOPS_EXECUTED_USED_CYCLES/CPU_CLK_UNHALTED_CORE
|
|
Unused cycles ratio [%] = 100*UOPS_EXECUTED_STALL_CYCLES/CPU_CLK_UNHALTED_CORE
|
|
Avg stall duration [cycles] = UOPS_EXECUTED_STALL_CYCLES/UOPS_EXECUTED_STALL_CYCLES:EDGEDETECT

This performance group returns the ratios of used and unused cycles regarding
|
|
the execution stage in the pipeline. Used cycles are all cycles where uOPs are
|
|
executed while unused cycles refer to pipeline stalls. Moreover, the group
|
|
calculates the average stall duration in cycles.
