[Xen-devel] OVMF BoF @ KVM Forum 2015


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/ \

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.

Personally, 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.)

Anyway, here goes.
