Event Name Description Programming Info
UNC_CHA_CLOCKTICKS Counts clockticks of the clock controlling the uncore caching and home agent (CHA). EventSel=00H UMask=00H Counter=0,1,2,3
UNC_CHA_CORE_SNP.CORE_GTONE Counts the number of transactions that trigger a configurable number of cross snoops. Cores are snooped if the transaction looks up the cache and determines that it is necessary based on the operation type and what CoreValid bits are set. For example, if 2 CV bits are set on a data read, the cores must have the data in S state so it is not necessary to snoop them. However, if only 1 CV bit is set the core my have modified the data. If the transaction was an RFO, it would need to invalidate the lines. This event can be filtered based on who triggered the initial snoop(s). EventSel=33H UMask=42H Counter=0,1,2,3
UNC_CHA_CORE_SNP.EVICT_GTONE Counts the number of transactions that trigger a configurable number of cross snoops. Cores are snooped if the transaction looks up the cache and determines that it is necessary based on the operation type and what CoreValid bits are set. For example, if 2 CV bits are set on a data read, the cores must have the data in S state so it is not necessary to snoop them. However, if only 1 CV bit is set the core my have modified the data. If the transaction was an RFO, it would need to invalidate the lines. This event can be filtered based on who triggered the initial snoop(s). EventSel=33H UMask=82H Counter=0,1,2,3

In the general case, Part3 refers to a x4 PCIe card plugged into the fourth slot of a PCIe riser card, but it could brefer to any device attached to the IIO unit using the lanes starting at lane 12 of the 16 lanes supported by the bus. EventSel=84H UMask=02H FCMask=07H PortMask=08H Counter=0,1,2,3
UNC_M_ACT_COUNT.WR Counts DRAM Page Activate commands sent on this channel due to a write request to the iMC (Memory Controller). Activate commands are issued to open up a page on the DRAM devices so that it can be read or written to with a CAS (Column Access Select) command. EventSel=01H UMask=02H Counter=0,1,2,3
UNC_M_CAS_COUNT.ALL Counts all CAS (Column Address Select) commands issued to DRAM per memory channel. CAS commands are issued to specify the address to read or write on DRAM, so this event increments for every read and write. This event counts whether AutoPrecharge (which closes the DRAM Page automatically after a read/write) is enabled or not. EventSel=04H UMask=0FH Counter=0,1,2,3
UNC_M_CAS_COUNT.RD Counts all CAS (Column Access Select) read commands issued to DRAM on a per channel basis. CAS commands are issued to specify the address to read or write on DRAM, and this event increments for every read. This event includes underfill reads due to partial write requests. This event counts whether AutoPrecharge (which closes the DRAM Page automatically after a read/write) is enabled or not. EventSel=04H UMask=03H Counter=0,1,2,3
UNC_M_CAS_COUNT.RD_REG Counts CAS (Column Access Select) regular read commands issued to DRAM on a per channel basis. CAS commands are issued to specify the address to read or write on DRAM, and this event increments for every regular read. This event only counts regular reads and does not includes underfill reads due to partial write requests. This event counts whether AutoPrecharge (which closes the DRAM Page automatically after a read/write) is enabled or not. EventSel=04H UMask=01H Counter=0,1,2,3
UNC_M_CAS_COUNT.RD_UNDERFILL Counts CAS (Column Access Select) underfill read commands issued to DRAM due to a partial write, on a per channel basis. CAS commands are issued to specify the address to read or write on DRAM, and this command counts underfill reads. Partial writes must be completed by first reading in the underfill from DRAM and then merging in the partial write data before writing the full line back to DRAM. This event will generally count about the same as the number of partial writes, but may be slightly less because of partials hitting in the WPQ (due to a previous write request). EventSel=04H UMask=02H Counter=0,1,2,3
UNC_M_CAS_COUNT.WR Counts all CAS (Column Address Select) commands issued to DRAM per memory channel. CAS commands are issued to specify the address to read or write on DRAM, and this event increments for every write.

UNC_M_POWER_CHANNEL_PPD Counts cycles when all the ranks in the channel are in PPD (PreCharge Power Down) mode. If IBT (Input Buffer Terminators)=off is enabled, then this event counts the cycles in PPD mode. If IBT=off is not enabled, then this event counts the number of cycles when being in PPD mode could have been taken advantage of. EventSel=85H UMask=00H Counter=0,1,2,3
UNC_M_POWER_SELF_REFRESH Counts the number of cycles when the iMC (memory controller) is in self-refresh and has a clock. This happens in some ACPI CPU package C-states for the sleep levels. For example, the PCU (Power Control Unit) may ask the iMC to enter self-refresh even though some of the cores are still processing. One use of this is for Intel? Dynamic Power Technology. Self-refresh is required during package C3 and C6, but there is no clock in the iMC at this time, so it is not possible to count these cases. EventSel=43H UMask=00H Counter=0,1,2,3
UNC_M_PRE_COUNT.PAGE_MISS Counts the number of explicit DRAM Precharge commands sent on this channel as a result of a DRAM page miss. This does not include the implicit precharge commands sent with CAS commands in Auto-Precharge mode. This does not include Precharge commands sent as a result of a page close counter expiration. EventSel=02H UMask=01H Counter=0,1,2,3
UNC_M_PRE_COUNT.RD Counts the number of explicit DRAM Precharge commands issued on a per channel basis due to a read, so as to close the previous DRAM page, before opening the requested page. EventSel=02H UMask=04H Counter=0,1,2,3
UNC_M_RPQ_INSERTS Counts the number of read requests allocated into the Read Pending Queue (RPQ). This queue is used to schedule reads out to the memory controller and to track the requests. Requests allocate into the RPQ soon after they enter the memory controller, and need credits for an entry in this buffer before being sent from the CHA to the iMC. The requests deallocate after the read CAS command has been issued to DRAM. This event counts both Isochronous and non-Isochronous requests which were issued to the RPQ. EventSel=10H UMask=00H Counter=0,1,2,3
UNC_M_RPQ_OCCUPANCY Counts the number of entries in the Read Pending Queue (RPQ) at each cycle. This can then be used to calculate both the average occupancy of the queue (in conjunction with the number of cycles not empty) and the average latency in the queue (in conjunction with the number of allocations). The RPQ is used to schedule reads out to the memory controller and to track the requests. Requests allocate into the RPQ soon after they enter the memory controller, and need credits for an entry in this buffer before being sent from the CHA to the iMC. They deallocate from the RPQ after the CAS command has been issued to memory. EventSel=80H UMask=00H Counter=0,1,2,3

UNC_M_TAGCHK.MISS_DIRTY Tag Check; Dirty EventSel=D3H UMask=04H Counter=0,1,2,3
UNC_M_WPQ_INSERTS Counts the number of writes requests allocated into the Write Pending Queue (WPQ). The WPQ is used to schedule writes out to the memory controller and to track the requests. Requests allocate into the WPQ soon after they enter the memory controller, and need credits for an entry in this buffer before being sent from the CHA to the iMC (Memory Controller). The write requests deallocate after being issued to DRAM. Write requests themselves are able to complete (from the perspective of the rest of the system) as soon they have 'posted' to the iMC. EventSel=20H UMask=00H Counter=0,1,2,3
UNC_M_WPQ_OCCUPANCY Counts the number of entries in the Write Pending Queue (WPQ) at each cycle. This can then be used to calculate both the average queue occupancy (in conjunction with the number of cycles not empty) and the average latency (in conjunction with the number of allocations). The WPQ is used to schedule writes out to the memory controller and to track the requests. Requests allocate into the WPQ soon after they enter the memory controller, and need credits for an entry in this buffer before being sent from the CHA to the iMC (memory controller). They deallocate after being issued to DRAM. Write requests themselves are able to complete (from the perspective of the rest of the system) as soon they have 'posted' to the iMC. This is not to be confused with actually performing the write to DRAM. Therefore, the average latency for this queue is actually not useful for deconstruction intermediate write latencies. So, we provide filtering based on if the request has posted or not. By using the 'not posted' filter, we can track how long writes spent in the iMC before completions were sent to the HA. The 'posted' filter, on the other hand, provides information about how much queueing is actually happening in the iMC for writes before they are actually issued to memory. High average occupancies will generally coincide with high write major mode counts. EventSel=81H UMask=00H Counter=0,1,2,3
UNC_I_CACHE_TOTAL_OCCUPANCY.MEM Total IRP occupancy of inbound read and write requests. This is effectively the sum of read occupancy and write occupancy. EventSel=0FH UMask=04H Counter=0,1

UNC_UPI_TxL_BYPASSED Counts incoming FLITs (FLow control unITs) which bypassed the TxL(transmit) FLIT buffer and pass directly out the UPI Link. Generally, when data is transmitted across the Intel® Ultra Path Interconnect (UPI), it will bypass the TxQ and pass directly to the link.
