virtio: add full three-clause BSD text to headers.

2011-05-30T01:44:14+00:00

It's unclear to me if it's important, but it's obviously causing my
technical colleages some headaches and I'd hate such imprecision to
slow virtio adoption.

I've emailed this to all non-trivial contributors for approval, too.

virtio_pci: optional MSI-X support

2009-06-12T12:46:37+00:00

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.

virtio: Don't use PAGE_SIZE for vring alignment in virtio_pci.

2008-12-29T22:55:58+00:00

That doesn't work for non-4k guests which are now appearing.

virtio: Don't use PAGE_SIZE in virtio_pci.c

2008-12-29T22:55:57+00:00

The virtio PCI devices don't depend on the guest page size.  This matters
now PowerPC virtio is gaining ground (they like 64k pages).

virtio: clarify that ABI is usable by any implementations

2008-07-25T02:06:04+00:00

We want others to implement and use virtio, so it makes sense to BSD
license the non-__KERNEL__ parts of the headers to make this crystal
clear.

virtio: Use PCI revision field to indicate virtio PCI ABI version

2008-02-04T12:50:12+00:00

As Avi pointed out, as we continue to massage the virtio PCI ABI, we can make
things a little more friendly to users by utilizing the PCI revision field to
indicate which version of the ABI we're using.  This is a hard ABI version
and incrementing it will cause the guest driver to break.

This is the necessary changes to virtio_pci to support this.

virtio: PCI device

2008-02-04T12:50:11+00:00

This is a PCI device that implements a transport for virtio.  It allows virtio
devices to be used by QEMU based VMMs like KVM or Xen.
