Hi Michael,
In commit 1a937693993f ("virtio: new feature to detect IOMMU device quirk"),
you added a new feature bit (VIRTIO_F_IOMMU_PLATFORM) to describe whether
or not a given virtio device requires physical address or bus addresses.
Is there a plan to get this incorporated into the virtio spec [1]? At the
moment, I can't see a working draft that includes the new bit. Having it
in the spec would help convince implementors that it's not just a Linux
thing.
Thanks,
Will

Absolutely. Want to contribute a patch?

I could have a look. Is there a git repo for the sources to the working
draft?

Yes, though unfortunately it's svn :(
git svn clone --stdlayout https://tools.oasis-open.org/version-control/svn/virtio
Check out the main branch.
Patches must be sent to virtio-dev or virtio-comments list (subscription
required).
Thanks!

A faster way is to go through a git mirror. See
https://tools.oasis-open.org/version-control/svn/virtio/trunk/git-svn.txt
section named "Faster initial clone from git mirror".
