Abstract:
1. A method comprising: receiving an upstream message generated by a downstream device, wherein the upstream message is received via a peripheral interface of an upstream device and does not require a response, wherein the peripheral interface is associated with a Peripheral Component Interconnect (PCI) Express bus; and sending an alert message from the upstream device to the downstream device via the peripheral interface indicating that the received upstream message is corrupted by an error, such that the downstream device can generate: debug information in response to the alert message, and directly output the debug information associated with the error for debugging the error, wherein the alert message comprises a PCI Express vendor-defined message type-1 packet associated with a peripheral device, and information associated with an uncorrectable error status register, and wherein the upstream device is operable to send a completion message to indicate that a request from the downstream device was not successful in addition to sending the alert message to the downstream device.
