Tsirkin <mst@xxxxxxxxxx> There's one concern here: are we going to add a feature flag for flexible layout? If yes this feature could thinkably just reuse it. It allows a nice optimization in virtio net that is very easy with latest qemu. Rusty, what is our plan wrt this? Are you fine with a per-device feature bit? Or do we need a transport feature bit (there's the small issue that we almost run out of them for virtio-pci, do we use the last one?). As an aside, the new virtio pci config proposal seems to be stuck too, are you looking into it or want me to? -- MST _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
