  • what is the real question here? are you asking how is the `SRAM memory of NIC used for packet processing in DPDK`? If yes, simple answer it is same way how Linux, BSD or WIndows uses the NIC for RX and TX packets. If the question is related to `RDMA`, please rephrase to make it clear – Vipin Varghese Jun 14 '22 at 12:33

You can see the code in the artifact at: https://github.com/BorisPis/nicmem-asplos22-artifact

In essence, there's an API exposed in upstream rdma-core's libibverbs that exposes it, and you can see the dpdk patches for an example.

    Thank you so much for answering it. I've already found the API docs (https://docs.nvidia.com/networking/display/OFEDv502180/Programming#Programming-DeviceMemoryProgramming); And the *NICMEM* is really an excellent job! – lizebin Jun 15 '22 at 07:09
