Hi all,
Could you please help to review this patch set? In this patch set, the IoLib instance BaseIoLibIntrinsic is modified to support AMD SEV feature and the BaseIoLibIntrinsicSev is removed.
Also could you help to do a test on AMD processor to make sure that the SEV feature still works good with this patch set?
Thanks,
Dun

Thanks for the suggestion.
I'll update the test result once I finished the test. Also the abstract message in this patch has been modified to mention that this patch should not be merged now.
Thanks,
Dun

Here is my suggestion:
1) Please perform the test to ensure the functional part is correct.
Without that, how can people know you are doing things right?
2) If you do not run any test, before you send out patch, please call out that clearly.
That is important to reminder the maintainer: Don't merge, even if it pass review.
Otherwise, once the review passed, the maintainer may merge it.
I don't think that is the intention.
Thank you
Yao, Jiewen
