592 * High level "TopDown" CPU core pipe line bottleneck break down.
594 * Basic concept following
595 * Yasin, A Top Down Method for Performance analysis and Counter architecture
598 * The CPU pipeline is divided into 4 areas that can be bottlenecks:
600 * Frontend -> Backend -> Retiring
601 * BadSpeculation in addition means out of order execution that is thrown away
602 * (for example branch mispredictions)
603 * Frontend is instruction decoding.
604 * Backend is execution, like computation and accessing data in memory
605 * Retiring is good execution that is not directly bottlenecked
607 * The formulas are computed in slots.
608 * A slot is an entry in the pipeline each for the pipeline width
609 * (for example a 4-wide pipeline has 4 slots for each cycle)
612 * BadSpeculation = ((SlotsIssued - SlotsRetired) + RecoveryBubbles) /
614 * Retiring = SlotsRetired / TotalSlots
615 * FrontendBound = FetchBubbles / TotalSlots
616 * BackendBound = 1.0 - BadSpeculation - Retiring - FrontendBound
618 * The kernel provides the mapping to the low level CPU events and any scaling
619 * needed for the CPU pipeline width, for example:
621 * TotalSlots = Cycles * 4
623 * The scaling factor is communicated in the sysfs unit.
625 * In some cases the CPU may not be able to measure all the formulas due to
626 * missing events. In this case multiple formulas are combined, as possible.
628 * Full TopDown supports more levels to sub-divide each area: for example
629 * BackendBound into computing bound and memory bound. For now we only
630 * support Level 1 TopDown.
