[Qemu-devel] [PATCH 4/6] vhost-user: support registering external host notifiers

2018-05-24 Thread Tiwei Bie
This patch introduces VHOST_USER_PROTOCOL_F_HOST_NOTIFIER. With this feature negotiated, vhost-user backend can register memory region based host notifiers. And it will allow the guest driver in the VM to notify the hardware accelerator at the vhost-user backend directly. Signed-off-by: Tiwei Bie
