Abstract: Methods and systems for sharing access to a computer resource accessible by a bus between two controllers are provided. For example, a machine implemented method of sharing access to computer resources includes requesting access to a bus from a processor of a first controller to access a device shared with a processor of a second controller; waiting for a positive response from the second controller; when the positive response is received, accessing the bus for less than a first timeout period; resetting a timer before the timer reaches the first timeout period to extend access to the bus, when access is not complete and a total access time is less than a second timeout period; and releasing the bus when access is complete or the second timeout period has been reached.

Abstract: Systems and methods for dynamically programming retimers for computer communications are disclosed. For example, in one aspect, a machine implemented method is disclosed that includes: detecting a cable related event at a port coupled to another device via a cable; determine a cable type and a cable length from a storage location of the port; determining if the cable type and the cable length are different from a previously stored cable type and cable length connecting the port to the other device; and when either the cable type or the cable length are different than the previously stored cable type and cable length, programming a retimer device based on the cable type and length.
