592 | * High level "TopDown" CPU core pipe line bottleneck break down. | |
593 | * | |
594 | * Basic concept following | |
595 | * Yasin, A Top Down Method for Performance analysis and Counter architecture | |
596 | * ISPASS14 | |
597 | * | |
598 | * The CPU pipeline is divided into 4 areas that can be bottlenecks: | |
599 | * | |
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 | |
606 | * | |
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) | |
610 | * | |
611 | * Formulas: | |
612 | * BadSpeculation = ((SlotsIssued - SlotsRetired) + RecoveryBubbles) / | |
613 | * TotalSlots | |
614 | * Retiring = SlotsRetired / TotalSlots | |
615 | * FrontendBound = FetchBubbles / TotalSlots | |
616 | * BackendBound = 1.0 - BadSpeculation - Retiring - FrontendBound | |
617 | * | |
618 | * The kernel provides the mapping to the low level CPU events and any scaling | |
619 | * needed for the CPU pipeline width, for example: | |
620 | * | |
621 | * TotalSlots = Cycles * 4 | |
622 | * | |
623 | * The scaling factor is communicated in the sysfs unit. | |
624 | * | |
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. | |
627 | * | |
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. | |
