[PATCH V4 0/3] virtio-pci: introduce modern device module

[Jason Wang]

Hi all:

This series tries to implement a vDPA driver for virtio-pci device
which will bridge between vDPA bus and virtio-pci device.

This could be used for future feature prototyping and testing.

Please review

Changes since V4:
- include the patch to let VIRTIO_PCI_LIB to be auto selected
- style fixes in the Kconfig for vp-vdpa driver
- fix the err value returned during vp-vdpa driver probing

Changes since V3:
- rebase to vhost.git

Changes since V2:

- tweak config prompt
- switch from 'cb' to 'config_cb' for vp_vdpa config interrupt
- use a macro for vp_vdpa msix name length

Changes since V1:

- don't try to use devres for virtio-pci core
- tweak the commit log
- split the patches furtherly to ease the reviewing

Changes since RFC:

- Split common codes from virito-pci and share it with vDPA driver
- Use dynamic id in order to be less confusing with virtio-pci driver
- No feature whitelist, supporting any features (mq, config etc)

  virtio: don't prompt CONFIG_VIRTIO_PCI_MODERN
  vdpa: set the virtqueue num during register
  vdpa: introduce virtio pci driver
