[edk2-devel] SPDM Transports

We are actively implementing generic SPDM support into our codebase, starting with the code in EDK2. However, we are now trying to separate the SPDM code from PCI DoE (to use MCTP, for example). Right now it seems the EDK2 version is hardcoded for PCI DoE. We would like to add some abstraction and are considering adding a separate driver that can sit on top of the MCTP layer. Do you think we should pursue the driver model or do you have another way to support multiple SPDM transports?

Thanks,

Hey Tim,

From my understanding the SPDM support in EDK2 is still very new and
not yet (at least last time I looked) actually connected to anything.

Supporting a range of SPDM transports is important. It's not just MCTP
and DOE, but the storage (ATA, SCSI and NVMe) protocols as well that
should be supported.

It would be great if any abstraction takes into account a range of
transport methods, at least allowing them to be implemented later. I'm
currently slowly working towards DOE support [1], but if you are able
to design a general SPDM abstraction that would be great and I would
be happy to help where I can, although I'm not an EDK2 expert.
