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. Signed-off-by: Michael S.

Here's an updated vesion. I'm alternating between updating the spec and the driver, spec update to follow. Compiled only. Posting here for early feedback, and to allow Sasha to proceed with his "kvm tool" work. Changes from v2: address comments by Rusty bugfixes by Sasha Changes from v1: Updated to match v3 of the spec, see: todo: split core changes out Signed-off-by:

Add a flexible mechanism to specify virtio configuration layout, using pci vendor-specific capability. A separate capability is used for each of common, device specific and data-path accesses. Warning: compiled only. This patch also needs to be split up, pci_iomap changes also need arch updates for non-x86. There might also be more spec changes. Posting here for early feedback, and to allow

Let host know of our state (partial yet) so that the host PCI device is up to where we were when we were suspended. This is still an RFC as this doesn't completely work: an unused device at the time of suspend will work fine after resume, but a device that has seen some activity doesn't behave well after resume. Especially, host->guest communication doesn't go through. This could
