[edk2-devel] [PATCH 0/2] Quo vadis virtio-mmio?

[Gerd Hoffmann]

virtio-mmio support in ovmf seems to be the unloved child.  The final
virto-1.0 specification was published five(!) years ago, nevertheless
the mmio transport doesn't support it yet ...

Some people argue that it has been obsoleted by virtio-pci.  Which is a
valid argument.  But IMHO isn't a good reason to just let virtio-mmio
bitrot.  We should either remove it from the tree, or support it.

So, opening the discussion with this little patch series.  It does the
latter and adds virtio 1.0 support.  For the mmio transport the
difference between 0.9.5 and 1.0 is rather small (when compared to the
pci transport), it is just a bunch of new registers for the changed
virtio queue initialization.  So the patch series is small too ...

take care,
  Gerd
