Hi All: This series tries to add the support for control virtqueue in vDPA. Control virtqueue is used by networking device for accepting various commands from the driver. It's a must to support multiqueue and other configurations. When used by vhost-vDPA bus driver for VM, the control virtqueue should be shadowed via userspace VMM (Qemu) instead of being assigned directly to Guest. This is

Hi all: This is an update version of vDPA support in kernel. vDPA device is a device that uses a datapath which complies with the virtio specifications with vendor specific control path. vDPA devices can be both physically located on the hardware or emulated by software. vDPA hardware devices are usually implemented through PCIE with the following types: - PF (Physical Function) - A single

Hi all: This is an updated version of kernel support for vDPA device. Various changes were made based on the feedback since last verion. One major change is to drop the sysfs API and leave the management interface for future development, and introudce the incremental DMA bus operations. Please see changelog for more information. The work on vhost, IFCVF (intel VF driver for vDPA) and qemu is
