To clarify something: 1) I did not enable SMI handler profile for OVMF because I notice the= OVMF just use very few SMI handlers, and it does not have SmmChildDispatch= er. Just like what you mentioned. 2) I forget to mention: I did regression test for OVMF IA32 and IA32X= 64 with default SmiHandlerProfile is DISABLED. I boot to UEFI SHELL only, and I do not enter OS. I think the risk is very low, because if SMI handler profile is disabled, t= here is no code logic change. VOID SmmCoreInitializeSmiHandlerProfile ( VOID ) { EFI_STATUS Status; VOID *Registration; EFI_HANDLE Handle; if ((PcdGet8 (PcdSmiHandlerProfilePropertyMask) & 0x1) !=3D 0) { InsertTailList (&mRootSmiEntryList, &mRootSmiEntry.AllEntries); Status =3D gSmst->SmmRegisterProtocolNotify ( &gEfiSmmReadyToLockProtocolGuid, SmmReadyToLockInSmiHandlerProfile, &Registration ); ASSERT_EFI_ERROR (Status); Handle =3D NULL; Status =3D gSmst->SmmInstallProtocolInterface ( &Handle, &gSmiHandlerProfileGuid, EFI_NATIVE_INTERFACE, &mSmiHandlerProfile ); ASSERT_EFI_ERROR (Status); } } I do understand your concern, because OVMF has some special feature which m= ight be different with real hardware. At same time, I have to mention that, it is very hard to setup KVM in Linux= . I did try to follow your description before on NX. I spent one week, but still fail to launch the final image on my side, I ha= ve no idea on what is wrong. That was a horrible experience. I will have a try to follow your new document. If it can be setup successfully, easily and fortunately, I do want to run i= t.

Thanks for the CC. This module seems quite large, and OVMF (to my knowledge) doesn't include a= ny special handlers. (Nothing from category (3), and I couldn't say if anyt= hing from category (2)). Do you think this module would be useful to enable in OVMF, conditionally, = with -D SMI_HANDLER_PROFILE_ENABLE? Beyond the question of its utility to OVMF developers and users, requiring = a separate UEFI app to dump the profile, presumably from the UEFI shell, is= not really flexible for OVMF. We can't / don't build applications into the= firmware image (beyond the shell and UiApp), so users would have to build = a virtual disk image with this app, or we'd have to provide scripts for the= same. For now, I believe we don't wish to enable this in OVMF. If you CC'd me for regression-testing PiSmmCore, as it is built into OVMF, = with the default PcdSmiHandlerProfilePropertyMask=3D0 value, then I respect= fully point you to the following article: https://github.com/tianocore/tianocore.github.io/wiki/Testing-SMM-with-QEMU= ,-KVM-and-libvirt Please set up a KVM environment as documented there, and adopt it for regul= ar SMM testing :) My strong hope is that, by adopting KVM as a regular test= platform, Intel developers won't only catch OVMF regressions before they p= ost patches, but they should also see their own productivity increase. I assume it must be much easier to click "Play" in the Virt-Manager GUI and= to boot to an OS, on top of the new firmware, in seconds, than to flash fi= rmware to a physical board. It does not replace physical board testing, but= should catch a number of errors more gracefully. The test cases I wrote up include UEFI variable testing and ACPI S3. The gu= est OSes covered are Fedora 25 and Windows 10. Please give it a look. Thanks!
