Sensor Data Record (SDR)
Every sensor on the Base Board is associated with a Sensor Data Record (SDR). Sensor Data
Records contain information about the sensor’s identification such as sensor type, sensor
name, sensor unit. SDR also contain the configuration of a specific sensor such as thresh-
old/hystheresis and event generation capabilities that specifies sensor behaviour. Some field
of the sensor SDR are configurable through IPMI v1.5 commands and are set to built-in initial
value. The AT8902 management controller supports sensor devices and uses the IPMI dynam-
ic sensor population feature of IPMI v1.5 to merge the AMC hot swap sensor with the AT8902
sensors population. AMC hot swap events indicated by this sensor are passed to the ShMC.
Additionally, the IPMC updates the sensor population change indicator timestamp accessible
through the Get Device SDR Info command to remain compliant to IPMI v1.5.
All SDRs can be queried using Device SDR commands. Base Board sensors that have been
implemented are listed below.
