Hi Rashmica,

Thank you for reply. The LF is means openbmc community.

I think is has some typo for the link:
https://gerrit.openbmc.org/c/openbmc/libpldm/+/58057
https://gerrit.openbmc.org/c/openbmc/pldm/+/58058
https://gerrit.openbmc.org/c/openbmc/pldm/+/58059

Could you help make sure the code above is up to date?

In addition, do you have a plan for when this feature will be completed?
We are willing to assist in revising and testing to ensure its workability.


Thanks,
Delphine

Hi Delphine,

Apologies if you get two replies, my email client is playing up and I'm pretty sure my last reply didn't go through.

I can only access the first link, but that commit and the other two that were needed with it are out of date. I'm not sure what you mean by "LF"?

This commit message explains the current approach:
https://gerrit.openbmc.org/c/openbmc/libpldm/+/59576

Steps 1 and 2 are done. 3 and 4 are in progress, but progress is very slow as I have been unwell since early 2023.

There is now an instance id API (upstream) and transport API (upstream but not stable), and eventually there will be a requester API, and hopefully a responder API one day.

- pldmd needs conversion to transport API. This is being held up by making the transport API requester/responder agnostic.
https://gerrit.openbmc.org/c/openbmc/pldm/+/63652
- other applications need conversion to to instance id API and transport API
- then pldmd and other upstream applications will move over to AF_MCTP

If you want to help, let me know. Otherwise the easiest way to use upstream and get AF_MCTP working is to change the transport objects and function calls in libpldm/src/requester/pldm.c from pldm_transport_mctp_demux to pldm_transport_af_mctp


Cheers,
Rashmica
