Abstract: Methods, systems, and devices for providing computer implemented services are disclosed. To provide the computer implemented services, an identification of a startup of a data processing system may be made. Based on the identification, a determination may be made regarding whether a device is present in an expansion slot of the data processing system. If the device is present, then another determination may be made regarding whether identification information is able to be obtained from the device. If obtained, the identification information may be interpreted to obtain communication link bifurcation settings for the device. Default communication link training settings may then be updated based on the bifurcation settings to obtain updated training settings. Communication link training may then be initiated for a communication link using the updated training settings.

Abstract: Managing PCIe slots, including identifying a table, stored at a database, indicating, for each PCIe card, a number of PCIe slots to be designated as inaccessible to other PCIe cards; detecting coupling of a particular PCIe card to a particular PCIe slot; accessing, in response to detecting the coupling of the particular PCIe card to the particular PCIe slot, the table; determining, based on the accessing, that the table includes data indicating the particular PCIe card; identifying, based on determining that the table includes data indicating the particular PCIe card, the number of PCIe slots adjacent to the particular slot to be designated as inaccessible to other PCIe cards; adjusting, based on the number of PCIe slots adjacent to the particular slot to be designated as inaccessible to other PCIe cards, a power state of one or more PCIe slots adjacent to the particular PCIe slot to an off-power state.
