Re: [edk2-devel] 回复: [edk2-devel] UEFI spec version in system table, shall we update it to 2.8?

[Michael D Kinney]

I do not think anyone has done the complete analysis since UEFI 2.7.  Some updates from newer specs
have been added as needed by different community members.

Unless there are dedicated tasks to review and verify that every spec change has been added to edk2, the version can not be updated.

Hi All,

Can you please share your thoughts if any idea in EDK2 compliance with UEFI 2.8 Support ?

From UEFI sources and latest edk2 master branch is still at 2.7. Same for latest stable tag edk2-stable202308.
https://github.com/tianocore/edk2.git
#define EFI_SYSTEM_TABLE_REVISION       EFI_2_70_SYSTEM_TABLE_REVISION
#define EFI_SPECIFICATION_VERSION       EFI_SYSTEM_TABLE_REVISION


But we could see some of the features from 2.8 is already available and UEFI 2.9 spec also released but system table in edk2 is still pointing to 2.7.

Curious to know, Whether latest edk2 is not fully compliance with 2.8 or only system table update is missing for 2.8

Thanks & Regards

In latest tianocore edk2 (https://github.com/tianocore/edk2 [github.com]<https://urldefense.com/v3/__https:/github.com/tianocore/edk2__;!!LpKI!mQ_BG3pFqn4l_WXu4-SMapIb2kzSZmeFEwZ9PNGLNx6j_YdYF6DUWQBuLZwoJhMzMQIiKG1dMBmDJH6eqgKzHbK-JfJWjjqXU1bQ$> ), we can see System table is still pointing to 2.70 Version(EFI_2_70_SYSTEM_TABLE_REVISION)

Does it mean latest tianocore is still not UEFI 2.8 version support or it supports 2.8 functionalities but the table version number is not yet updated?
