The granted patent (Publication Number: US11886374B2) discloses an apparatus designed for the Root Complex (RC) of a PCIe (Peripheral Component Interconnect express) system. The apparatus includes a memory and one or more processors configured to generate a PCIe VDM (Vendor Defined Message) message for an Endpoint (EP) of the PCIe system. This message can contain various information such as an interrupt trigger for the EP, details on the reset status at the RC, data path status, buffer status, and even error notifications, including fatal errors.

Furthermore, the patent describes an apparatus tailored for an EP of a PCIe system, equipped with a memory and processors capable of processing PCIe VDM messages from the RC. These messages can include crucial details like interrupt triggers, reset status, data path status, buffer status, and error information. The apparatus can also handle messages relayed by the RC from other EPs within the system, enhancing communication and error management within the PCIe infrastructure.
