Hi Liming, Hao, and all Now we're checking the SCT runtime variable service test case. https://github.com/tianocore/edk2-test/blob/92a0343c1553342c53fae9d9d646b763add232c0/uefi-sct/SctPkg/TestCase/UEFI/EFI/RuntimeServices/VariableServices/BlackBoxTest/VariableServicesBBTestConformance.c#L3401 and have a question below.
Is there any use case to call the runtime variable service functions with the Attributes that only has EFI_VARIABLE_NON_VOLATILE set? We checked UEFI spec, documents, and current EDK2 implementation. There is no specific description or any implementation for this. However, there seems an implication that EFI_VARIABLE_NON_VOLATILE must be set with at least EFI_VARIABLE_BOOTSERVICE_ACCESS. Actually, it looks like making NO sense to have a variable attribute combination that doesn't have any XXXXX_ACCESS attribute (BS, RT, or AT) set. Therefore, we think only having EFI_VARIABLE_NON_VOLATILE set may be an invalid case and would like to add a check into the EDK2 variable driver to return EFI_INVALID_PARAMETER. What do you guys think? Best Regards, Sunny IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
