Latest Patents
One of Johnson's latest patents is titled "Method and program code for identifying new nodes on a bus following a reset." This invention addresses the challenge of identifying new nodes on a bus after a reset by comparing the topologies of nodes before and after the reset. The method allows a host to identify itself in both the new and old topology data, facilitating the identification of matching nodes. Additionally, any new nodes lacking a corresponding match will prompt requests over the bus to obtain their identification data.
Another significant patent is the "Method and device for linking work requests with completion queue entries." This invention provides a systematic approach to linking work requests in a work queue with entries on a queue of completed requests. By creating a tracking list for each work queue, Johnson's method ensures that each entry contains the necessary information to uniquely associate a completion queue entry with the work request that caused it. This innovation streamlines the process of identifying work requests based on completion queue entries.
