More Information
Summary:A device connected by a link to a host system can include a first port to receive a capability configuration message across a link and a message request receiving logic comprising hardware circuitry to identify a capability of the device identified in the capability configuration message, determine that the capability is to be presented or hidden from operation based on a capability hide enable bit in the capability configuration message, and configure a capability linked list to present or hide the capability based on the determination. The device can also include a message response generator logic comprising hardware circuitry to generate a response message indicating that the capability is to be presented or hidden from operation. The device can include a second port to transmit the response message across the link.
