[PATCH 0/9] virtio_pci: split out legacy device support

From: Michael S. Tsirkin
Date: Mon Dec 08 2014 - 08:08:51 EST


virtio 1.0 support for virtio-pci isn't ready yet.
Therefore, this patchset doesn't make any functional changes.
Instead, this simply refactors virtio-pci, splitting legacy
device support code out to a separate file: virtio_pci_legacy.c

For virtio 1.0, all that's left is to add virtio_pci_modern.c
supporting
get_features
finalize_features
get (config)
set (config)
get_status
set_status
reset
setup_vq
del_vq
probe
remove

Most notably, tricky MSI-X vector probing logic stays
in common file: virtio_pci.c. version-specific only has
to code setup/del functions for individual vqs.

Note: this is on top of "virtio 1.0 enhancements"
that I sent earlier.

Michael S. Tsirkin (9):
virtio_pci: add isr field
virtio_pci: fix coding style for structs
virtio_pci: free up vq->priv
virtio_pci: use priv for vq notification
virtio_pci: delete vqs indirectly
virtio_pci: setup vqs indirectly
virtio_pci: setup config vector indirectly
virtio_pci: split out legacy device support
virtio_pci: update file descriptions and copyright
