Sorry for the late review. The change looks fine. However, I'm confused about the comment " Log the error here and return key states are not supported when high order bit of KeyToggleState is 0 or KeyState not touched". It looks like returning EFI_UNSUPPORTED won't log any error/failure in the result log. Did I overlook anything here?
Furthermore, it looks like UEFI spec implies that the ReadKeyStrokeEx should clear KeyState (set the value to zero) if there is no key data. There is also a code change for doing this in edk2. https://edk2.groups.io/g/devel/message/20311 Therefore, if I didn't overlook anything here, we should separately deal with the "(Key.KeyState.KeyShiftState == 0xFFFFFFFF) || (Key.KeyState.KeyToggleState == 0xFF)" as a failure rather than directly returning EFI_UNSUPPORTED. Barton and Edhaya, what do you guys think?
