IN-BAND CONFIGURATION MODE

摘要

A first state of an interconnect protocol is entered. A particular signal is sent according to the protocol to a device over a link. During the first state, it is detected that a response to the particular signal is received in the first state. It is determined that the device supports a configuration mode outside the protocol based on the received response. The configuration mode is entered based on the response. One or more in-band configuration messages are sent within the configuration mode.

主权项

1. An apparatus comprising:
state logic to enter a first state and to support a set of core configuration modes; a transmitter to send a particular signal to a device over a link during the first state; detection logic to detect that a response to the particular signal is received in the first state; configuration mode logic to:
determine that the device supports a particular configuration mode outside the core configuration modes based on the response;enter the particular configuration mode based on the response; andsend one or more in-band configuration messages to the device within the particular configuration mode.
