Abstract: A driver for a system component sensor device in a computer system comprises a diagnostic mode of operation configured for enabling selective execution of diagnostic functionality on a corresponding system component sensor device while concurrently permitting execution of system management to be performed via system component sensors in a system management mode of operation. The diagnostic mode of operation includes disabling the corresponding system component device with respect to system management functionality and access by non-diagnostic users. The driver further comprises at least one of a parent driver device interface configured for controlling modes of operation of a group of child sensor devices and a plurality of child device driver interfaces each configured for controlling modes of operation of a respective one of the child sensor devices.
