| P-core | ||
| INST_RETIRED.ANY | Counts the number of X86 instructions retired - an Architectural PerfMon event. Counting continues during hardware interrupts, traps, and inside interrupt handlers. Notes: INST_RETIRED.ANY is counted by a designated fixed counter freeing up programmable counters to count other events. INST_RETIRED.ANY_P is counted by a programmable counter. CORE: PCore | IA32_FIXED_CTR0 PEBS:[PreciseEventingIP, PDISTCounter=32] Architectural, Fixed, AtRetirement |
| CPU_CLK_UNHALTED.THREAD | Counts the number of core cycles while the thread is not in a halt state. The thread enters the halt state when it is running the HLT instruction. This event is a component in many key event ratios. The core frequency may change from time to time due to transitions associated with Enhanced Intel SpeedStep Technology or TM2. For this reason this event may have a changing ratio with regards to time. When the core frequency is constant, this event can approximate elapsed time while the core was not in the halt state. It is counted on a dedicated fixed counter, leaving the eight programmable counters available for other events. CORE: PCore | IA32_FIXED_CTR1 PEBS:[NonPreciseEventingIP] Architectural, Fixed, Speculative |
| CPU_CLK_UNHALTED.REF_TSC | Counts the number of reference cycles when the core is not in a halt state. The core enters the halt state when it is running the HLT instruction or the MWAIT instruction. This event is not affected by core frequency changes (for example, P states, TM2 transitions) but has the same incrementing frequency as the time stamp counter. This event can approximate elapsed time while the core was not in a halt state. It is counted on a dedicated fixed counter, leaving the eight programmable counters available for other events. Note: On all current platforms this event stops counting during 'throttling (TM)' states duty off periods the processor is 'halted'. The counter update is done at a lower clock rate then the core clock the overflow status bit for this counter may appear 'sticky'. After the counter has overflowed and software clears the overflow status bit and resets the counter to less than MAX. The reset value to the counter is not clocked immediately so the overflow status bit will flip 'high (1)' and generate another PMI (if enabled) after which the reset value gets clocked into the counter. Therefore, software will get the interrupt, read the overflow status bit '1 for bit 34 while the counter value is less than MAX. Software should ignore this case. CORE: PCore | IA32_FIXED_CTR2 PEBS:[NonPreciseEventingIP] Architectural, Fixed, Speculative |
| TOPDOWN.SLOTS | Number of available slots for an unhalted logical processor. The event increments by machine-width of the narrowest pipeline as employed by the Top-down Microarchitecture Analysis method (TMA). The count is distributed among unhalted logical processors (hyper-threads) who share the same physical core. Software can use this event as the denominator for the top-level metrics of the TMA method. This architectural event is counted on a designated fixed counter (Fixed Counter 3). CORE: PCore | IA32_FIXED_CTR3 PEBS:[NonPreciseEventingIP] Architectural, Fixed, Speculative |
| BR_INST_RETIRED.ALL_BRANCHES | Counts all branch instructions retired. CORE: PCore | EventSel=C4H UMask=00H Counter=0,1,2,3,4,5,6,7 CounterHTOff=0,1,2,3,4,5,6,7 PEBS:[PreciseEventingIP, Counter=0,1,2,3,4,5,6,7, PDISTCounter=0] Architectural, AtRetirement |
| BR_MISP_RETIRED.ALL_BRANCHES | Counts all the retired branch instructions that were mispredicted by the processor. A branch misprediction occurs when the processor incorrectly predicts the destination of the branch. When the misprediction is discovered at execution, all the instructions executed in the wrong (speculative) path must be discarded, and the processor must start fetching from the correct path. CORE: PCore | EventSel=C5H UMask=00H Counter=0,1,2,3,4,5,6,7 CounterHTOff=0,1,2,3,4,5,6,7 PEBS:[PreciseEventingIP, Counter=0,1,2,3,4,5,6,7, PDISTCounter=0] Architectural, AtRetirement |
| CPU_CLK_UNHALTED.REF_TSC_P | Counts the number of reference cycles when the core is not in a halt state. The core enters the halt state when it is running the HLT instruction or the MWAIT instruction. This event is not affected by core frequency changes (for example, P states, TM2 transitions) but has the same incrementing frequency as the time stamp counter. This event can approximate elapsed time while the core was not in a halt state. It is counted on a dedicated fixed counter, leaving the four (eight when Hyperthreading is disabled) programmable counters available for other events. Note: On all current platforms this event stops counting during 'throttling (TM)' states duty off periods the processor is 'halted'. The counter update is done at a lower clock rate then the core clock the overflow status bit for this counter may appear 'sticky'. After the counter has overflowed and software clears the overflow status bit and resets the counter to less than MAX. The reset value to the counter is not clocked immediately so the overflow status bit will flip 'high (1)' and generate another PMI (if enabled) after which the reset value gets clocked into the counter. Therefore, software will get the interrupt, read the overflow status bit '1 for bit 34 while the counter value is less than MAX. Software should ignore this case.

| CPU_CLK_UNHALTED.THREAD_P | This is an architectural event that counts the number of thread cycles while the thread is not in a halt state. The thread enters the halt state when it is running the HLT instruction. The core frequency may change from time to time due to power or thermal throttling. For this reason, this event may have a changing ratio with regards to wall clock time. CORE: PCore | EventSel=3CH UMask=00H Counter=0,1,2,3,4,5,6,7 CounterHTOff=0,1,2,3,4,5,6,7 PEBS:[NonPreciseEventingIP, Counter=0,1,2,3,4,5,6,7] Architectural, Speculative |
