  • Patent number: 10817458
    Abstract: This disclosure describes techniques for extending a range of bidirectional bus communications through the use of a differential signal path. The disclosed techniques include first separating the bidirectional bus into first and second unidirectional buses that transmit and receive signals, respectively, and then communicating the signals from the first and second unidirectional buses over a differential signal path. The separation of the bidirectional bus into the first and second unidirectional buses is performed using logic circuitry that blocks or permits communication between a given one of the first and second buses and the bidirectional bus based on whichever one of the first and second buses becomes dominant first. If the logic circuitry determines that the first bus becomes dominant before the second bus, the logic circuitry permits communications between the first bus and the bidirectional bus and blocks communications between the second bus and the bidirectional bus.

  • Patent number: 10684976
    Abstract: A firmware enumerates the buses of root bridges in the computing system. If an OOR condition occurs during enumeration of the buses, the firmware determines the number of required buses for each root bridge causing an OOR condition. The number of required buses for bridge devices connected to each root bridge causing an OOR condition can be identified using the same set of bus numbers. Once the firmware has determined the number of buses required by each root bridge, including those not causing an OOR condition, the firmware reallocates the number of available buses between the root bridges such that each root bridge is allocated a number of the available buses greater than or equal to the number of required buses. The firmware stores data identifying the allocation and restarts the computing device. Upon rebooting, the computing system utilizes the new allocation of bus numbers to eliminate the OOR condition.

  • Patent number: 10635149
    Abstract: Embodiments discussed herein refer to systems, methods, and circuits for conforming to power up sequencing rules of a conventional hard-wired data connection even though the hard-wired data connection that would ordinarily exist between two data controllers has been replaced with one or more contactless connectors. A consequence of replacing the hard-wired connection with a contactless connector is that the data controllers no longer directly control the power sequencing between the controllers because they are not able to directly communicate with each other over the hard-wired data connections. Power sequence assist circuitry may be used to assists the data controllers in establishing a link in accordance with the power sequencing rules of a particular wired interface despite the intentionally broken hard-wired data connection between the two controllers by instructing the contactless connectors to communicate with their respective data controllers in compliance with the power sequencing rules.
