Hi folks,

It seems there is no code to enable stack alignment check in EDK2, while it is required to be enabled according to UEFI spec v2.6, section 2.3.6, page 38.

Shall we find somewhere to enable SA?

SA implies 16 byte alignment of the stack. Are we sure all existing asm code is 16 byte clean?

Not sure; but I think it is also an issue if SA is not enabled, for it is not UEFI specification compliant. Please advise.

Thanks,
