[PATCHv5 2/3] virtio_pci: split up vp_interrupt
This reorganizes virtio-pci code in vp_interrupt slightly, so that
it's easier to add per-vq MSI support on top.

[PATCHv6 4/4] virtio_pci: optional MSI-X support
This implements optional MSI-X support in virtio_pci.
MSI-X is used whenever the host supports at least 2 MSI-X
vectors: 1 for configuration changes and 1 for virtqueues.
Per-virtqueue vectors are allocated if enough vectors
available.

RFC: sharing config interrupt between virtio devices for saving MSI
Hi all,
I'm working on this item in Upstream Networking todolist:
| - Sharing config interrupts
| Support more devices by sharing a single msi vector
| between multiple virtio devices.
| (Applies to virtio-blk too).
I have this solution here, and only have draft patches of Solution
1 & 2, let's discuss if solution 3 is feasible.
* We should not introduce perf regression in

[PATCH 2/9] virtio_pci: use shared interrupts for virtqueues
This lets IRQ layer handle dispatching IRQs to separate handlers for the
case where we don't have per-VQ MSI-X vectors, and allows us to greatly
simplify the code based on the assumption that we always have interrupt
vector 0 (legacy INTx or config interrupt for MSI-X) available, and
any other interrupt is request/freed throught the VQ, even if the
actual interrupt line might be shared in some

[PATCH 1/9] virtio_pci: remove struct virtio_pci_vq_info
We don't really need struct virtio_pci_vq_info, as most field in there
are redundant:
- the vq backpointer is not strictly neede to start with
- the entry in the vqs list is not needed - the generic virtqueue already
has list, we only need to check if it has a callback to get the same
semantics
- we can use a simple array to look up the MSI-X vec if needed.
- That simple array now
