Jiewen, I'd like to request the following: - Please separate the fix for the incorrect parameter passing to SmiRendezvous() out to a separate patch. It is my understanding that the issue exists already in the master branch. Is that right? If it is, then the fix should not be tied to the SMM page level protection feature. - Please give that patch to Jeff. Jeff, can you please repost your series [edk2] [PATCH v2 0/3] Put AP into safe hlt-loop code on S3 path to edk2-devel, as v3, with Jiewen's patch from above included, as patch#4? Because, I would like to see a patch series that addresses all known S3 issues that we've uncovered in this investigation. The first three patches should fix BZ#216, yes. The last (4th) patch, from Jiewen, is unrelated to that BZ indeed, but it nonetheless addresses an existent issue in PiSmmCpuDxeSmm that can be hit during S3. My goal is to apply that series (the first 3 patches from Jeff, and the fourth patch from Jiewen), and to test it as one unit. I'd like to see if those changes fix the infrequent, but still triggerable issues with S3+SMM, for both Ia32 and Ia32X64. If everything works fine, then that series should be committed. After that, I'd like to test Jiewen's v4 series for the SMM page level protection, separately. In other words, first we should fix the existent bugs that Jiewen's SMM page level protection feature only amplifies (but doesn't introduce) on QEMU/KVM + OVMF. Once the known bugs are fixed, I'll be glad to test the new feature. Would this work for you guys? Thank you, Laszlo > with DEBUG message update you suggested. > > My unit test failed before.
