The Protocol/Ppi used in the drivers but the it not add them in the dependence section, it may cause driver assert. This patch series add the missed Protocol/Ppi. Eric Dong (2): UefiCpuPkg/CpuFeaturesDxe.inf: Add missed Depex protocol. UefiCpuPkg/CpuFeaturesPei.inf: Add missed Depex Ppi.

I grepped the directory for both protocol and PPI, and I found no matches. If the dependencies are incurred via library instances, then those library instances should spell out the depex. The only library class used by CpuFeaturesDxe.inf and CpuFeaturesPei.inf, for which multi-processing looks remotely relevant, is: RegisterCpuFeaturesLib. For this class, two instances appear to exist: UefiCpuPkg/Library/RegisterCpuFeaturesLib/DxeRegisterCpuFeaturesLib.inf UefiCpuPkg/Library/RegisterCpuFeaturesLib/PeiRegisterCpuFeaturesLib.inf The DXE instance consumes gEfiMpServiceProtocolGuid alright, but it also spells out the protocol in the depex: [Depex] gEfiMpServiceProtocolGuid AND gEdkiiCpuFeaturesSetDoneGuid The PEI instance is similar, wrt. the PPI: [Depex] gEfiPeiMpServicesPpiGuid AND gEdkiiCpuFeaturesSetDoneGuid So, this series appears unnecessary. What am I missing? Thanks Laszlo _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
Hi Laszlo, Agree with you, I'm not aware the consume protocol/Ppi code is in the library till now. I will discard the changes.
