The intent here is to only search the UEFI DB from a DXE/UEFI driver and the SMM DB from an SMM driver and not to cross between. So which protocol DB is searched is purely a function of the module type (i.e. what instance of the ProtocolLib it was linked against). This is analogous to what is done with MemoryAllocationLib which either allocates from the UEFI memory pools for UEFI/DXE modules (UefiMemoryAllocationLib instance) or from the SMM memory pools for SMM modules (SmmMemoryAllocationLib). Sorry I wasn't more clear initially. Eugene _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
