[. . . ] Since the Processor does not have an SERRB signal, SERR messages are passed from the Processor to the PCH over DMI. When a bit in this register is set, a SERR message will be generated on DMI whenever the corresponding flag is set in the ERRSTS register. The actual generation of the SERR message is globally enabled for Device #0 via the PCI Command register.

Error Command Registers Bit 15:12 11 Access RO RW Default Value 000b 0b RST/ PWR Core Core Reserved SERR on Processor Thermal Sensor Event (TSESERR): 1: The Processor generates a DMI SERR special cycle when bit 11 of the ERRSTS is set. The SERR must not be enabled at the same time as the SMI for the same thermal sensor event. 0: Reporting of this condition via SERR messaging is disabled. Reserved SERR on LOCK to non-DRAM Memory (LCKERR): 1: The Processor will generate a DMI SERR special cycle whenever a CPU lock cycle is detected that does not hit DRAM. 0: Reporting of this condition via SERR messaging is disabled Reserved SERR on DRAM Throttle Condition (ERR): 0 = Reporting of this condition via SERR messaging is disabled. 1 = The memory controller generates a DMI SERR special cycle when a DRAM Read or Write Throttle condition occurs. Reserved SERR Multiple-Bit DRAM ECC Error (DMERR): 1: The Processor generates an SERR message over DMI when it detects a multiple-bit error reported by the DRAM controller. 0: Reporting of this condition via SERR messaging is disabled. For systems not supporting ECC this bit must be disabled. SERR on Single-bit ECC Error (DSERR): 1: The Processor generates an SERR special cycle over DMI when the DRAM controller detects a single bit error. 0: Reporting of this condition via SERR messaging is disabled. For systems that do not support ECC this bit must be disabled.

When an error flag is set in the ERRSTS register, it can generate an SERR, SMI, or SCI DMI special cycle when enabled in the ERRCMD, SMICMD, or SCICMD registers respectively. Note that one and only one message type can be enabled. SMI Command Registers Bit 15:12 11 Access RO RW Default Value 0h 0b RST/ PWR Core Core Reserved SMI on Processor Thermal Sensor Trip (TSTSMI): 1: A SMI DMI special cycle is generated by Processor when the thermal sensor trip requires an SMI. A thermal sensor trip point cannot generate more than one special cycle. 0: Reporting of this condition via SMI messaging is disabled. Reserved SMI on Multiple-Bit DRAM ECC Error (DMESMI): 1: The Processor generates an SMI DMI message when it detects a multiple-bit error reported by the DRAM controller. 0: Reporting of this condition via SMI messaging is disabled. [. . . ] A value of 0 indicates that the table is not present (due to fixed VC priority). 23:8 7:0 RO RO 0000h 00h Core Core Reserved Reserved for VC Arbitration Capability (VCAC) 6. 3. 4PVCCTL - Port VC Control B/D/F/Type:0/6/0/MMR Address Offset:10C-10Dh Default Value:0000h Access: RO; RW; Size:16 bits Table 76.
