Dear All, Can some help in clarifying the what is the current UEFI Spec version support in latest tianocore edk2 In latest tianocore edk2 (https://github.com/tianocore/edk2 ), we can see System table is pointing to 2.70 Version(EFI_2_70_SYSTEM_TABLE_REVISION) https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Uefi/UefiSpec.h // // EFI Runtime Services Table // #define EFI_SYSTEM_TABLE_SIGNATURE SIGNATURE_64 ('I','B','I',' ','S','Y','S','T') #define EFI_2_80_SYSTEM_TABLE_REVISION ((2 << 16) | (80)) #define EFI_2_70_SYSTEM_TABLE_REVISION ((2 << 16) | (70)) #define EFI_2_60_SYSTEM_TABLE_REVISION ((2 << 16) | (60)) #define EFI_2_50_SYSTEM_TABLE_REVISION ((2 << 16) | (50)) #define EFI_2_40_SYSTEM_TABLE_REVISION ((2 << 16) | (40)) #define EFI_2_31_SYSTEM_TABLE_REVISION ((2 << 16) | (31)) #define EFI_2_30_SYSTEM_TABLE_REVISION ((2 << 16) | (30)) #define EFI_2_20_SYSTEM_TABLE_REVISION ((2 << 16) | (20)) #define EFI_2_10_SYSTEM_TABLE_REVISION ((2 << 16) | (10)) #define EFI_2_00_SYSTEM_TABLE_REVISION ((2 << 16) | (00)) #define EFI_1_10_SYSTEM_TABLE_REVISION ((1 << 16) | (10)) #define EFI_1_02_SYSTEM_TABLE_REVISION ((1 << 16) | (02)) #define EFI_SYSTEM_TABLE_REVISION EFI_2_70_SYSTEM_TABLE_REVISION #define EFI_SPECIFICATION_VERSION EFI_SYSTEM_TABLE_REVISION #define EFI_RUNTIME_SERVICES_SIGNATURE SIGNATURE_64 ('R','U','N','T','S','E','R','V') #define EFI_RUNTIME_SERVICES_REVISION EFI_SPECIFICATION_VERSION Does it mean latest tianocore is still at UEFI 2.7 version support or it supports 2.8 functionalities but table version number is not yet updated ? How to check whether latest edk2 support UEFI 2.8 or not ?
