[edk2-devel] question about EDKII_IOMMU_PROTOCOL

[Tiger Liu(BJ-RD)]

Hi, Experts:
I find EDKII_IOMMU_PROTOCOL definition in MdeModulePkg\Include\Protocol\IoMmu.h .

But I didn't find its define in UEFI Spec or PI Spec.
So, is it a private protocol definition?

Thanks

Yes -- that's why the protocol name starts with the "EDKII_" prefix, and
why the header file is under MdeModulePkg and not MdePkg.

It's an "implementation detail" in edk2.
