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 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)
Thanks
