Gerd, The S3 path has been 64bit ready. Can you check if OVMF pei64 image can do s3?
At least internally in some real platform we tested s3 flow with 64bit PEI.

Intel seems to be working on removing the IA32 dependency, by adding full X64 support to various places in the code base. There have been numerous patch sets on the list over the last months, some of them are merged meanwhile. As far I know the patch series addressing the suspend problem is not yet merged (Ray, Jiewen, please correct me if I'm wrong). So, right now we still need that, but I expect that to change in near future. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
