Abstract
Described embodiments provide a media controller for processing a diagnostic request received from a diagnostic source. The received diagnostic request is parsed by a corresponding request handling module of the media controller, where each diagnostic source type has a corresponding request handling module. If the received diagnostic request requires allocation of buffer space, a common diagnostic handling module of the media controller allocates buffer space in a buffer for the received diagnostic request. The common diagnostic handling module is common for all diagnostic source types. The common diagnostic handling module provides the received diagnostic request to a corresponding one of a plurality of end diagnostic handling modules. The end diagnostic handling module performs the diagnostic tasks. If the received diagnostic request requires a transfer of data to the diagnostic source, the common diagnostic handling module performs the data transfer between the media controller and the diagnostic source.
