[PATCH 0/6] mdev based hardware virtio offloading support

Hi all: There are hardware that can do virtio datapath offloading while having its own control path. This path tries to implement a mdev based unified API to support using kernel virtio driver to drive those devices. This is done by introducing a new mdev transport for virtio (virtio_mdev) and reg

[PATCH 1/6] mdev: class id support

Mdev bus only supports vfio driver right now, so it doesn't implement match method. But in the future, we may add drivers other than vfio, one example is virtio-mdev[1] driver. This means we need to add device class id support in bus match method to pair the mdev device and mdev driver correctly.

[PATCH 2/6] mdev: introduce device specific ops

Currently, except for the create and remove. The rest of mdev_parent_ops is designed for vfio-mdev driver only and may not help for kernel mdev driver. Follow the class id support by previous patch, this patch introduces device specific ops pointer inside parent ops which points to device specific
