ATTR_CEN_DQ_TO_DIMM_CONN_DQ TARGET_TYPE_DIMM Centaur DQ to DIMM connector DQ mapping. Uint8 value for each Centaur DQ (0-79). The value is the corresponding DIMM Connector DQ. Therefore if (data[2] == 60) then Centaur DQ 2 maps to DIMM DQ 60 If the logical DIMM is on a Centaur-DIMM then the value is the same as the array index because there is no DIMM connector. If the logical DIMM is an IS-DIMM then the value depends on board wiring. uint8 80 ATTR_CEN_MBA_PORT TARGET_TYPE_DIMM MBA Chiplet port this DIMM is connected to uint8 ATTR_CEN_MBA_DIMM TARGET_TYPE_DIMM MBA port DIMM number of this DIMM uint8 ATTR_CEN_VPD_DIMM_SPARE TARGET_TYPE_MBA Spare DRAM availability for all DIMMs connected to the target MBA. For each rank on a DIMM, there are 8 DQ lines to spare DRAMs. - NO_SPARE: No spare DRAMs - LOW_NIBBLE: x4 DRAMs in use, one spare DRAM connected to SP_DQ0-3 - HIGH_NIBBLE: x4 DRAMs in use, one spare DRAM connected to SP_DQ4-7 - FULL_BYTE: Either 1/ x4 DRAMs in use, two spare DRAMs connected to SP_DQ0-7 2/ x8 DRAMs in use, one spare DRAM connected to SP_DQ0-7 For C-DIMMs, this is in a VPD field : Record:VSPD, Keyword:AM uint8 NO_SPARE = 0x00, LOW_NIBBLE = 0x01, HIGH_NIBBLE = 0x02, FULL_BYTE = 0x03 2 2 4 ATTR_CEN_MBVPD_VERSION TARGET_TYPE_MEMBUF_CHIP Memory Buffer VPD version, written and consumed by the MB vpd accessor functions (see getMBvpdAttr.C). uint32
