HI Abner,
Moving the IPMI related PCD’s will cause additional package dependencies.
Suppose if someone wants to implement SPMI table using DynamicTablesPkg (and using this PCD);
then it will cause dependencies on ManageabilityPkg which is not accepted.
Thanks

Hi Sean,
I was struggling when introduce IPMI KCS base IO PCD in Mde, although it is a industry value but seems it is fine to have it in ManageabilityPkg. How do you think if we relocate those IPMI PCDs back to ManageabilityPkg?
Thanks
Abner

Caution: This message originated from an External Source. Use proper caution when opening attachments, clicking links, or responding.
This seems like a bad design to require the ipmi interface type at such a high level in the code tree. UEFI provides plenty protocol and library abstractions for IPMI so I would really prefer not to leak this type of information into a PCD defined in MdePkg. Happy to discuss IPMI support and I would really like to see edk2, edk2-platforms/Features/ManageabilityPkg at master · tianocore/edk2-platforms (github.com)<https://github.com/tianocore/edk2-platforms/tree/master/Features/ManageabilityPkg>, microsoft/mu_feature_ipmi: Project Mu - Feature Repo- Firmware support for IPMI (github.com)<https://github.com/microsoft/mu_feature_ipmi>, and commercial vendors find some sort of alignment going forward as no one wins with the mess that is in the industry now.
Thanks
Sean
