* virtio: add full three-clause BSD text to headers.Rusty Russell2011-05-301-0/+23
| | | | | | | | | | | | | | | | | | 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 supportMichael S. Tsirkin2009-06-121-1/+9
| | | | | | | | | | | | 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.

* virtio: Don't use PAGE_SIZE for vring alignment in virtio_pci.Rusty Russell2008-12-301-0/+4
| | | | | | That doesn't work for non-4k guests which are now appearing. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* virtio: Don't use PAGE_SIZE in virtio_pci.cRusty Russell2008-12-301-0/+4
| | | | | | | The virtio PCI devices don't depend on the guest page size. This matters now PowerPC virtio is gaining ground (they like 64k pages). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* virtio: clarify that ABI is usable by any implementationsRusty Russell2008-07-251-3/+2
| | | | | | | | | | | | | 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 versionAnthony Liguori2008-02-041-0/+2
| | | | | | | | | | | | 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 deviceAnthony Liguori2008-02-041-0/+55
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. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
