[edk2-devel] [edk2] Smbuslib and SmbusPpi

[Liming Gao]

SmbusPpi is defined in PI spec. SmbusLib is defined in Edk2 MdePkg.

Edk2 PEIM can base on SmBusLib. SmBusLib implementation wraps SmBusPpi.

Thanks

Subject: [edk2-devel] [edk2] Smbuslib and SmbusPpi

Hi, Liming:
I have a question about smbus access during pei phase.

I found there was not smbus ppi reference implementation in edk2-platform code base.
And there was a SmbusLib reference implementation lib.

So, PEIMs usually use functions provided by SmbusLib?
Not use PeiSmbusPpi’s interface functions?

Thanks

Best wishes,
