Setting a bit to 1indicates that the associated device is present andits temperature should be monitored. Deviceenumeration corresponds to bit-position in the bitmask.These bytes are only valid if the Memory DeviceGroup ID field is not set to FFh (unspecified).This command must be supported on boththe SMS and SMM mode Note2Provides a method for the BIOS to:Enable a supported fan control profile.Communicate the memory throttling modeto the BMC (CLTT).Provide an indication to the BMC that theBIOS has completed setup of memorythrottling and DIMM temp sensor state.Provide memory temp sensor availabilitydata to the BMC.On BMC reset or power-up:The default enabled fan profile for a givenfan control domain is the lowest numberedprofile that is supported in the loadedSDRs.If no profiles are fully supported across allconfigured fan domains, the BMC defaultsto profile 0.Only CLTT is supported for Emerald RidgeThe definition of the Memory Device PresenceBit-map (bytes 4 to 11) for Emerald Ridge is asfollows:Bits 31:0 are used for indicating thepresence of a DIMM temp device.( For DIMM Bit map, please refer Table 22and Table 23)Bits 39:32 are used for indicating thepresence of a memory buffer temp device(One DIMM group can have a maximum oftwo Risers – for ex, Group 0 would haveRiser 1 and Riser 2.
