Xeon-Phi-Coprocessor-Datasheet

The sensor names in the IPMI SDR are static and do not change from release to
release. The IPMI sensor numbers are not static and may change between releases;
hence the sensor number should be discovered during the normal sensor discovery
process because additional sensors may be added in the future.
During the normal sensor discovery process, reading the SDR returns the sensors
available on the coprocessor. There is a sensor name and sensor number associated
with each sensor. Once the sensor number is determined by comparing the sensor
name that is desired to be read, the sensor number may be used by the management
firmware for reading a particular sensor. It is important that the firmware does not
hard code the sensor number as it may change in future releases. It is strongly
recommended to use the sensor name if it is "hard-coded" into the management
firmware to discover the sensor number, this will ensure the correct sensor is read and
will return valid data with future releases of the SMC firmware. Table 6-25 is a list of
the current sensor names.
