Mini-mezzanine Open Compute Project (OCP) How to Enable Plug-and-Play Network PHY Cards

摘要

Method and associated device for implementing mini - mezzanine Open Compute Project (OCP) plug - and - play network PHY cards. According to an aspect, the Media Access Channel (MAC) and Physical Layer (PHY) layer functions in one or more communication protocol stacks are installed in a platform controller hub (PCH) or a MAC block in a processor SoC, Lt; RTI ID = 0.0 PHY / RTI During platform initialization operations, the configuration parameters including the PHY card ID are read from the PHY card, the corresponding configuration script is selected and executed to configure the PHY card for use in the platform. Configuration parameters are also used to enumerate the PCIe devices associated with the ports and physical functions supported by the PHY card.
