[edk2-devel] [PATCH 0/7] Support Tdx and sev in BaseIoLibIntrinsic and remove BaseIoLibIntrinsicSev

[duntan]

Hi Jiewen,

Currently I'm working on the Tdx test. Since the patch set doesn't change the code logic when Tdx or SEV is enabled, so I want to send out the patch as soon as possible to see if there is any comments from community. 

I will include AMD SEV reviewer in this patch series. Thanks for reminding.

Thanks,
Dun

HI
Since this impact TDX and SEV, would you please let me know what kind of test you have done?
Have you validated TDX and SEV before you submit the patch? Please describe that clearly in your patch description.

Also please include AMD SEV reviewer in this patch series.

Thank you
Yao, Jiewen
