| CORE | ||
| INST_RETIRED.ANY | Counts the total number of instructions that retired. For instructions that consist of multiple uops, this event counts the retirement of the last uop of the instruction. This event continues counting during hardware interrupts, traps, and inside interrupt handlers. This event uses fixed counter 0. | IA32_FIXED_CTR0 PEBS:[PreciseEventingIP, PDISTCounter=0] Architectural, Fixed, AtRetirement |
| CPU_CLK_UNHALTED.CORE | Counts the number of core cycles while the core is not in a halt state. The core enters the halt state when it is running the HLT instruction. The core frequency may change from time to time. For this reason this event may have a changing ratio with regards to time. This event uses fixed counter 1. | IA32_FIXED_CTR1 PEBS:[NonPreciseEventingIP] Architectural, Fixed, Speculative |
| CPU_CLK_UNHALTED.REF_TSC | Counts the number of reference cycles that the core is not in a halt state. The core enters the halt state when it is running the HLT instruction. This event is not affected by core frequency changes and increments at a fixed frequency that is also used for the Time Stamp Counter (TSC). This event uses fixed counter 2. | IA32_FIXED_CTR2 PEBS:[NonPreciseEventingIP] Architectural, Fixed, Speculative |
| BR_INST_RETIRED.ALL_BRANCHES | Counts the total number of instructions in which the instruction pointer (IP) of the processor is resteered due to a branch instruction and the branch instruction successfully retires. All branch type instructions are accounted for. | EventSel=C4H UMask=00H Counter=0,1,2,3 CounterHTOff=NA PEBS:[PreciseEventingIP, Counter=0,1,2,3, PDISTCounter=0] Architectural, AtRetirement |
| BR_MISP_RETIRED.ALL_BRANCHES | Counts the total number of mispredicted branch instructions retired. All branch type instructions are accounted for. Prediction of the branch target address enables the processor to begin executing instructions before the non-speculative execution path is known. The branch prediction unit (BPU) predicts the target address based on the instruction pointer (IP) of the branch and on the execution path through which execution reached this IP. A branch misprediction occurs when the prediction is wrong, and results in discarding all instructions executed in the speculative path and re-fetching from the correct path. | EventSel=C5H UMask=00H Counter=0,1,2,3 CounterHTOff=NA PEBS:[PreciseEventingIP, Counter=0,1,2,3, PDISTCounter=0] Architectural, AtRetirement |
| CPU_CLK_UNHALTED.CORE_P | Counts the number of core cycles while the core is not in a halt state. The core enters the halt state when it is running the HLT instruction.
