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. This event has a constant ratio with the CPU_CLK_UNHALTED.REF_XCLK event. It is counted on a dedicated fixed counter, leaving the four (eight when Hyperthreading is disabled) programmable counters available for other events.

CPU_CLK_UNHALTED.THREAD

This event 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 four (eight when Hyperthreading is disabled) programmable counters available for other events.

CYCLE_ACTIVITY.STALLS_L2_PENDING

Each cycle there was a MLC-miss pending demand load and no uops dispatched on this thread (i.e. Non-completed valid SQ entry allocated for demand load and waiting for Uncore), increment by 1. Note this is in MLC and connected to Umask 0 and 2.

This event counts the number of uops not delivered to the back-end per cycle, per thread, when the back-end was not stalled. In the ideal case 4 uops can be delivered each cycle. The event counts the undelivered uops - so if 3 were delivered in one cycle, the counter would be incremented by 1 for that cycle (4 - 3). If the back-end is stalled, the count for this event is not incremented even when uops were not delivered, because the back-end would not have been able to accept them. This event is used in determining the front-end bound category of the top-down pipeline slots characterization.

This event counts the number of times that split load operations are temporarily blocked because all resources for handling the split accesses are in use.

LD_BLOCKS.STORE_FORWARD

This event counts loads that followed a store to the same address, where the data could not be forwarded inside the pipeline from the store to the load. The most common reason why store forwarding would be blocked is when a load's address range overlaps with a preceeding smaller uncompleted store. See the table of not supported store forwards in the Intel? 64 and IA-32 Architectures Optimization Reference Manual. The penalty for blocked store forwarding is that the load must wait for the store to complete before it can be issued.

Aliasing occurs when a load is issued after a store and their memory addresses are offset by 4K. This event counts the number of loads that aliased with a preceding store, resulting in an extended address check in the pipeline. The enhanced address check typically has a performance penalty of 5 cycles.

MEM_LOAD_UOPS_LLC_HIT_RETIRED.XSNP_HIT

This event counts retired load uops that hit in the last-level cache (L3) and were found in a non-modified state in a neighboring core's private cache (same package). Since the last level cache is inclusive, hits to the L3 may require snooping the private L2 caches of any cores on the same socket that have the line. In this case, a snoop was required, and another L2 had the line in a non-modified state.

MEM_LOAD_UOPS_LLC_HIT_RETIRED.XSNP_HITM

This event counts retired load uops that hit in the last-level cache (L3) and were found in a non-modified state in a neighboring core's private cache (same package). Since the last level cache is inclusive, hits to the L3 may require snooping the private L2 caches of any cores on the same socket that have the line. In this case, a snoop was required, and another L2 had the line in a modified state, so the line had to be invalidated in that L2 cache and transferred to the requesting L2.

MEM_LOAD_UOPS_LLC_HIT_RETIRED.XSNP_HITM_PS

This event counts retired load uops that hit in the last-level cache (L3) and were found in a non-modified state in a neighboring core's private cache (same package). Since the last level cache is inclusive, hits to the L3 may require snooping the private L2 caches of any cores on the same socket that have the line. In this case, a snoop was required, and another L2 had the line in a modified state, so the line had to be invalidated in that L2 cache and transferred to the requesting L2. (Precise Event - PEBS)

MEM_LOAD_UOPS_LLC_HIT_RETIRED.XSNP_HIT_PS

This event counts retired load uops that hit in the last-level cache (L3) and were found in a non-modified state in a neighboring core's private cache (same package). Since the last level cache is inclusive, hits to the L3 may require snooping the private L2 caches of any cores on the same socket that have the line. In this case, a snoop was required, and another L2 had the line in a non-modified state. (Precise Event - PEBS)

MEM_LOAD_UOPS_MISC_RETIRED.LLC_MISS_PS

This event counts retired demand loads that missed the last-level (L3) cache. This means that the load is usually satisfied from memory in a client system or possibly from the remote socket in a server. Demand loads are non speculative load uops. (Precise Event - PEBS)

UOPS_DISPATCHED_PORT.PORT_3

Cycles per thread when load or STA uops are dispatched to port 3

UOPS_DISPATCHED_PORT.PORT_3_CORE

Cycles per core when load or STA uops are dispatched to port 3

UOPS_DISPATCHED_PORT.PORT_4

Cycles per thread when uops are dispatched to port 4

UOPS_DISPATCHED_PORT.PORT_4_CORE

Cycles per core when uops are dispatched to port 4

UOPS_DISPATCHED_PORT.PORT_5

Cycles per thread when uops are dispatched to port 5

UOPS_DISPATCHED_PORT.PORT_5_CORE

Cycles per core when uops are dispatched to port 5

UOPS_EXECUTED.CORE_CYCLES_GE_1

Cycles at least 1 micro-op is executed from any thread on physical core

UOPS_EXECUTED.CORE_CYCLES_GE_2

Cycles at least 2 micro-op is executed from any thread on physical core

UOPS_EXECUTED.CORE_CYCLES_GE_3

Cycles at least 3 micro-op is executed from any thread on physical core

UOPS_EXECUTED.CORE_CYCLES_GE_4

Cycles at least 4 micro-op is executed from any thread on physical core

UOPS_EXECUTED.CORE_CYCLES_NONE

Cycles with no micro-ops executed from any thread on physical core

UOPS_ISSUED.ANY

This event counts the number of Uops issued by the front-end of the pipeilne to the back-end.

UOPS_ISSUED.CORE_STALL_CYCLES

Cycles when Resource Allocation Table (RAT) does not issue Uops to Reservation Station (RS) for all threads

UOPS_ISSUED.STALL_CYCLES

Cycles when Resource Allocation Table (RAT) does not issue Uops to Reservation Station (RS) for the thread

UOPS_RETIRED.ALL

This event counts the number of micro-ops retired.

UOPS_RETIRED.ALL_PS

This event counts the number of micro-ops retired. (Precise Event)

UOPS_RETIRED.CORE_STALL_CYCLES

Cycles without actually retired uops.

UOPS_RETIRED.RETIRE_SLOTS

This event counts the number of retirement slots used each cycle. There are potentially 4 slots that can be used each cycle - meaning, 4 micro-ops or 4 instructions could retire each cycle. This event is used in determining the 'Retiring' category of the Top-Down pipeline slots characterization.

UOPS_RETIRED.RETIRE_SLOTS_PS

This event counts the number of retirement slots used each cycle. There are potentially 4 slots that can be used each cycle - meaning, 4 micro-ops or 4 instructions could retire each cycle. This event is used in determining the 'Retiring' category of the Top-Down pipeline slots characterization. (Precise Event - PEBS)

UOPS_RETIRED.STALL_CYCLES

Cycles without actually retired uops.

UOPS_RETIRED.TOTAL_CYCLES

Cycles with less than 10 actually retired uops.
