Which linux framework is used is kind of beside the point but since you bring this up - not necessarily. E.g. I personally don't care much about "stack" but clearly we need a virtio driver on the host to be involved, teaching vfio about virtio is probably a much worse idea than creating a mode in the vdpa driver which mostly sets up the IOMMU and otherwise gets out of the way of using the VF and just drives the PF. But for example, to migrate cross-vendor you need the pci config space to look the same and for some devices this might mean that pci config space will have to be mediated. Or maybe not. vdpa is a good framework in that it gives us flexibility, it is not opinionated. -- MST --------------------------------------------------------------------- To unsubscribe, e-mail: virtio-dev-unsubscr...@lists.oasis-open.org For additional commands, e-mail: virtio-dev-h...@lists.oasis-open.org
