Formulas:
Used cycles ratio = UOPS_RETIRED_USED_CYCLES/CPU_CLK_UNHALTED_CORE
Unused cycles ratio = UOPS_RETIRED_STALL_CYCLES/CPU_CLK_UNHALTED_CORE
-
This performance group returns the ratios of used and unused CPU cycles. Here
unused cycles are cycles where no operation is performed due to some stall.
