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

This series adds support for the use of user virtual addresses in the vDPA simulator devices. The main reason for this change is to lift the pinning of all guest memory. Especially with virtio devices implemented in software. The next step would be to generalize the code in vdpa-sim to allow the implementation of in-kernel software devices. Similar to vhost, but using vDPA so we can reuse the

v2: - rebased on Linus' tree, commit ae3419fbac84 ("vc_screen: don't clobber return value in vcs_read") - removed `struct task_struct *owner` param (unused for now, maybe ?useful to support cgroups) [Jason] - add unbind_mm callback [Jason] - call the new unbind_mm callback during the release [Jason] - avoid to call bind_mm callback after the reset, since the device ?is not
