Today on the UEFI development list, Laszlo Ersek of Redhat announced an OVMF BOF at the upcoming KVM Forum, including Paolo Bonzini speaking on adding SMM to OVMF for KVM and Tianocore. This is a massive checkin, and having SMM in OVMF makes it a lot easier to trace and fuzz. Event aside, the list of the last year’s worth of changes to  OVMF/AVMF makes for an interesting read. Heavily-edited announcement follows:

Let’s do an OVMF BoF at this year’s KVM Forum too. Paolo will present “Securing secure boot: system management mode in KVM and Tiano Core” on Thursday, August 20, in the 5:00pm – 5:30pm time slot. Right after that, the BoF section starts at 5:30pm. We should convene and discuss stuff. I don’t have an agenda, so people should bring their ideas and questions (famous last words).

As food for thought, I tried to collect the feature-looking patches from the git history that have been committed since last year’s KVM Forum, and to match them against patch sets on the mailing list:

git log –reverse –oneline –since=2014-10-14 — OvmfPkg/ ArmVirtPkg/ ArmPlatformPkg/ArmVirtualizationPkg/

I attempted to sort them into categories. You can see the list below. The ordering is totally random, it’s just what I ended up with. Corrections / additions welcome. One (missing) feature I’d like to see discussed is: “SataControllerDxe in OVMF”. SMM will require Q35, and the only “IDE” that Q35 speaks is SATA / AHCI. (And you can’t disable that controller on Q35.)
