Hi @Nhi Pham<mailto:nhi@os.amperecomputing.com>,
I am sorry for taking so long to address your review comments. I updated pull request here: https://github.com/tianocore/edk2-platforms/pull/76
I addressed most of comments and I have questions about below review comments. Please find my feedback inline below.
> Should we add a PCD for the OEN to be configured by platform specific
> BMC? Or this protocol is only to support OpenBMC.
Yes, per description in Readme.md, this is the protocol only to support OpenBMC implementation.

With this implementation, user can call open directly and it will check the presence of blob for us. And yes, this is how we use it in NVIDIA driver.

Caller can only get the session ID by calling open(). Session ID is required when calling read, write, and commit. If caller make up a session ID, caller is expected to see error return.
> How do callers know the data format of metadata for writing correctly?
I check the spec here: https://github.com/openbmc/phosphor-ipmi-blobs?tab=readme-ov-file#bmcblobwritemeta-10 And there is no description about data format. Since we don't use this function in our driver, may I know if you have suggestion for this?

Sorry I don't follow you here.
gImageHandle is used as global variable in driver. But here we just use the ImageHandle from function parameter and we don't keep it as global variable, right?

Nickle

> > +## OpenBMC implements this interface as a protocol, allowing UEFI and BMC
> to transfer blobs over IPMI.
> > +
> > +### Usage:
> > +Any DXE module that wishes to use this protocol should do the following:
> > +1) The module should have a dependency on
> gEdkiiIpmiBlobTransferProtocolGuid in its inf "Depex" section
> > +2) The module should list gEdkiiIpmiBlobTransferProtocolGuid in its inf
> "Protocol" section
> > +3) The module's entry point should do a LocateProtocol on
> gEdkiiIpmiBlobTransferProtocolGuid
> > +
> > +### A sample flow of protocol usage is as follows:
> > +1) A call to IpmiBlobTransferOpen ()
> > +2) Iterative calls to IpmiBlobTransferWrite
> > +3) A call to IpmiBlobTransferClose ()
> > +
> > +### Unit Tests:
> > +IpmiBlobTransferDxe/UnitTest/ contains host based unit tests of this
> implementation.
> > +Any changes to IpmiBlobTransferDxe should include proof of successful unit
> tests.
> > +
> > +### Debugging
> > +To assist in debugging any issues, change BLOB_TRANSFER_DEBUG to desired
> debug level, such as DEBUG_ERROR or DEBUG_INFO.
