Apparently, the non-VM accelerated QEMU supports SMM, but we have not added support for this in OVMF. The VM accelerated QEMU+KVM doesn't support SMM. Usually you want to use KVM for the performance advantage, so most of the time SMM support would not be usable with OVMF. I think Laszlo's s3_v2 (not v3) branch at: https://github.com/lersek/edk2.git may have set up an environment that pretended to support those SMM protocols. But, I don't think that would get you very far in working on a real SMM driver. -Jordan ------------------------------------------------------------------------------ Start Your Social Network Today - Download eXo Platform Build your Enterprise Intranet with eXo Platform Software Java Based Open Source Intranet - Social, Extensible, Cloud Ready Get Started Now And Turn Your Intranet Into A Collaboration Platform http://p.sf.net/sfu/ExoPlatform _______________________________________________ edk2-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/edk2-devel
