Mike You are right. I forget adding EFI_OEM_SPECIFIC flag. I will use that flag in V5 patch.

Jiewen, Are these default values allocated from the OEM extension areas? Or are the allocated from the PI Spec reserved areas? I do not think we should use values reserved for future PI Specifications. I am ok with EDK II defining its own extended status codes. However, the detailed description of each of these PCDs needs to add a note that states that the default value is a value that does not conflict with the PI Specification or any other EDK II defined status code values. Platforms may need to override these values to prevent conflict with other OEM defined status code values.

That is good question. I follow the EDKII guideline to add new status code into code. If we need a new status code, which is not defined in PI spec, we will use PCD to avoid conflict. The benefit is that 1) The IBV/OEM implementation may choose to override this value, if the value is already used. 2) We can change the default value, if the value is used in future PI spec. We have below examples in current code base: C:\home\EdkIIGit\edk2\MdeModulePkg\MdeModulePkg.dec(797): gEfiMdeModulePkgTokenSpaceGuid.PcdProgressCodeOsLoaderLoad|0x03058000|UINT32|0x30001030 C:\home\EdkIIGit\edk2\MdeModulePkg\MdeModulePkg.dec(803): gEfiMdeModulePkgTokenSpaceGuid.PcdProgressCodeOsLoaderStart|0x03058001|UINT32|0x30001031 C:\home\EdkIIGit\edk2\MdeModulePkg\MdeModulePkg.dec(809): gEfiMdeModulePkgTokenSpaceGuid.PcdProgressCodeS3SuspendStart|0x03078000|UINT32|0x30001032 C:\home\EdkIIGit\edk2\MdeModulePkg\MdeModulePkg.dec(815): gEfiMdeModulePkgTokenSpaceGuid.PcdProgressCodeS3SuspendEnd|0x03078001|UINT32|0x30001033 C:\home\EdkIIGit\edk2\SecurityPkg\SecurityPkg.dec(300): gEfiSecurityPkgTokenSpaceGuid.PcdStatusCodeSubClassTpmDevice|0x010D0000|UINT32|0x00000007 That is why I add them to be new PCD.

Jiewen, Can you explain how you allocated the progress code values for capsule related operations? How do you guarantee these will not conflict with future versions of PI specifications? Also, is there a reason to make these PCDs? If these can be fixed values in extensible value regions of PI Status Codes, then couldn't #defines in a .h file be used instead of adding more PCDs?
