Subject[PATCH V2 00/14] vDPA driver for virtio-pci device
Date
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 from V1:

- 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)

Thanks

Jason Wang (14):
virtio-pci: do not access iomem via virtio_pci_device directly
virtio-pci: switch to use devres for modern devices
virtio-pci: split out modern device
virtio-pci: move the notification sanity check to vp_modern_probe()
virtio-pci-modern: introduce vp_modern_set_queue_vector()
virtio-pci-modern: introduce vp_modern_queue_address()
virtio-pci-modern: introduce helper to set/get queue_enable
virtio-pci-modern: introduce helper for setting/geting queue size
virtio-pci-modern: introduce helper for getting queue nums
virtio-pci-modern: introduce helper to get notification offset
virtio-pci: introduce modern device module
vdpa: set the virtqueue num during register
virtio_vdpa: don't warn when fail to disable vq
vdpa: introduce virtio pci driver
