This patch introduce a vDPA driver for virtio-pci device. It bridges the virtio-pci control command to the vDPA bus. This will be used for developing new features for both software vDPA framework and hardware vDPA feature. Compared to vdpa_sim, it has several advantages: - it's a real device driver which allow us to play with real hardware features - type independent instead of networking

Hi all: This series introduce basic functionality of doorbell mapping support for vhost-vDPA. Userspace program may use mmap() to map a the doorbell of a specific virtqueue into its address space. This is help to reudce the syscall or vmexit overhead. A new vdpa_config_ops was introduced to report the location of the doorbell, vhost_vdpa may then choose to map the doorbell when: - The doorbell

Live migration of vdpa would typically require re-instate vdpa device with an idential set of configs on the destination node, same way as how source node created the device in the first place. In order to allow live migration orchestration software to export the initial set of vdpa attributes with which the device was created, it will be useful if the vdpa tool can report the config on demand
