Ah, you are right. Sorry, I missed that. I've checked the v2 series now and I see the SkipXd label and friends are introduced by v2; it's not preexistent code. This means it should be okay for me to test these series as they are. No need to move patches between them. > So, that means we still have other unknown problem on S3 boot issue. Hm, with your above explanation, I'm actually not sure about that. I think that your series [edk2] [PATCH v2 0/3] Put AP into safe hlt-loop code on S3 path has a good chance to fix it all. I hope I can test it today. (And once I'm done with it, I'll move to Jiewen's v3.) Thanks!
