In Xilinx, the completion of a request is denoted by a specific bit in the RC descriptor, while in Intel, there is no analogous bit to indicate the conclusion of the last completion packet in a read request. How can these differences be correlated?

    Hi @thanavignesh,


    Thank you for your patience.


    Yes, there is no specific bit to indicate the last completion TLP in a read request.


    You may check out the Section (A.2. TLP Packet Formats with Data Payload) in User Guide below to find out the Completion with Data TLP packet format.

    I hope these answer your inquiry.


    Thanks.
