[Qemu-devel] plan for device assignment upstream

["Michael S. Tsirkin" <mst@redhat.com>]

I've been thinking hard about Jan's patches for device
assignment. Basically while I thought it makes sense
to make all devices: assignment and not - behave the
same and use same APIs for injecting irqs, Anthony thinks there is huge
value in making irq propagation hierarchical and device assignment
should be special cased.

We seem to be at impasse for now and I think merging
assignment ASAP has higher value than this specific
issue. So I fold - let's do it as Anthony and Jan's
original patches proposed.

Jan, can you please rebase and repost your original patchset (against
master, not against pci) that added query for host irqs callbacks for
device assignment? I'll re-review ignoring the idea of using the cache,
with intent apply after I'll drop cache code from the pci branch in a
couple of days (busy otherwise now).

I still intend to rework this later on, but that can wait.

Thanks,
