IMT_FULL
• Title: IMT Full
• Category: In-Flight Memory Table
• Event Code: 0x16, Max. Inc/Cyc: 1, PERF_CTL: 3,
• Definition: Number of times In-Flight Memory Table was full when entry was needed by incoming
transaction.
IMT_INSERTS_ALL
• Title: IMT All Inserts
• Category: In-Flight Memory Table
• Event Code: 0x07, Max. Inc/Cyc: 1, PERF_CTL: 1,
• Definition: Inserts (all requests) to In-Flight Memory Table (e.g. all memory transactions targeting
this B-Box as their home node and processed by this B-Box)
• NOTE: Conflicts and AckConflicts are considered IMT insert events. If the conflict rate (CONFLICTS/
IMT_INSERTS_ALL * 100) is > ~5%, it is not recommended that this event (along with
IMT_VALID_OCCUPANCY) be used to derive average IMT latency or latency for specific flavors of
inserts.
IMT_INSERTS_INVITOE
• Title: IMT InvItoE Inserts
• Category: In-Flight Memory Table
• Event Code: 0x0F, Max. Inc/Cyc: 1, PERF_CTL: 1,
• Definition: In-Flight Memory Table inserts of InvItoE requests (e.g. all InvItoE memory transactions
targeting this B-Box as their home node and processed by this B-Box)
• NOTE: Conflicts and AckConflicts are considered IMT insert events. If the conflict rate (CONFLICTS/
IMT_INSERTS_ALL * 100) is > ~5%, it is not recommended that this event (along with
IMT_VALID_OCCUPANCY) be used to derive average IMT latency or latency for specific flavors of
inserts.
IMT_INSERTS_IOH
• Title: IMT IOH Inserts
• Category: In-Flight Memory Table
• Event Code: 0x0A, Max. Inc/Cyc: 1, PERF_CTL: 1,
• Definition: In-Flight Memory Table inserts of IOH requests (e.g. all IOH triggered memory
transactions targeting this B-Box as their home node and processed by this B-Box)
• NOTE: Conflicts and AckConflicts are considered IMT insert events. If the conflict rate (CONFLICTS/
IMT_INSERTS_ALL * 100) is > ~5%, it is not recommended that this event (along with
IMT_VALID_OCCUPANCY) be used to derive average IMT latency or latency for specific flavors of
inserts.
IMT_INSERTS_IOH_INVITOE
• Title: IMT IOH InvItoE Inserts
• Category: In-Flight Memory Table
• Event Code: 0x10, Max. Inc/Cyc: 1, PERF_CTL: 1,
• Definition: In-Flight Memory Table inserts of IOH InvItoE requests (e.g. all IOH triggered InvItoE
memory transactions targeting this B-Box as their home node and processed by this B-Box)
• NOTE: Conflicts and AckConflicts are considered IMT insert events. If the conflict rate (CONFLICTS/
IMT_INSERTS_ALL * 100) is > ~5%, it is not recommended that this event (along with
IMT_VALID_OCCUPANCY) be used to derive average IMT latency or latency for specific flavors of
inserts.
