2013-03-01hw: include hw header files with full pathsPaolo Bonzini
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2013-03-01virtio-9p: remove PCI dependencies from hw/9pfs/Paolo Bonzini
Also move the 9p.h file to 9pfs/virtio-9p-device.h, for consistency with the corresponding .c file. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-01-21virtio-pci: refactor virtio-pci device.KONRAD Frederic
Create the virtio-pci device which is abstract. This transport device will create a virtio-pci-bus, so one VirtIODevice can be connected. Signed-off-by: KONRAD Frederic <fred.konrad@greensocs.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-01-21virtio-pci-bus: introduce virtio-pci-bus.KONRAD Frederic
Introduce virtio-pci-bus, which extends virtio-bus. It is used with virtio-pci transport device. Signed-off-by: KONRAD Frederic <fred.konrad@greensocs.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-01-07virtio-pci: cache msix messagesMichael S. Tsirkin
Some guests mask a vector then unmask without changing it. Store vectors to avoid kvm system calls in this case. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-01-07virtio: don't waste irqfds on control vqsMichael S. Tsirkin
Pass nvqs to set_guest_notifiers. This makes it possible to save on irqfds by not allocating one for the control vq for virtio-net. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-11-16virtio-rng: hardware random number generator deviceAmit Shah
The Linux kernel already has a virtio-rng driver, this is the device implementation. When the guest asks for entropy from the virtio hwrng, it puts a buffer in the vq. We then put entropy into that buffer, and push it back to the guest.

2012-05-21virtio-blk: define VirtIOBlkConfPaolo Bonzini
We will have to add another field to the virtio-blk configuration in the next patch. Avoid a proliferation of arguments to virtio_blk_init. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-05-21virtio/vhost: Add support for KVM in-kernel MSI injectionJan Kiszka
Make use of the new vector notifier to track changes of the MSI-X configuration of virtio PCI devices. On enabling events, we establish the required virtual IRQ to MSI-X message route and link the signaling eventfd file descriptor to this vIRQ line. That way, vhost-generated interrupts can be directly delivered to an in-kernel MSI-X consumer like the x86 APIC.
