| CORE | ||
| INST_RETIRED.ANY | This event counts the number of instructions retired from execution. For instructions that consist of multiple micro-ops, this event counts the retirement of the last micro-op of the instruction. Counting continues during hardware interrupts, traps, and inside interrupt handlers. INST_RETIRED.ANY is counted by a designated fixed counter, leaving the programmable counters available for other events. Faulting executions of GETSEC/VM entry/VM Exit/MWait will not count as retired instructions. Errata: HSD140, HSD143 |
IA32_FIXED_CTR0 Architectural, Fixed |
| CPU_CLK_UNHALTED.THREAD | This event 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. | IA32_FIXED_CTR1 Architectural, Fixed |
| CPU_CLK_UNHALTED.THREAD_ANY | Core cycles when at least one thread on the physical core is not in halt state. | IA32_FIXED_CTR1 Architectural, Fixed |
| CPU_CLK_UNHALTED.REF_TSC | This event 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. | IA32_FIXED_CTR2 Architectural, Fixed |
