vhost: introduce API to start a specific driver We used to use rte_vhost_driver_session_start() to trigger the vhost-user session. It takes no argument, thus it's a global trigger. And it could be problematic. The issue is, currently, rte_vhost_driver_register(path, flags) actually tries to put it into the session loop (by fdset_add). However, it needs a set of APIs to set a vhost-user driver properly: * rte_vhost_driver_register(path, flags); * rte_vhost_driver_set_features(path, features); * rte_vhost_driver_callback_register(path, vhost_device_ops); If a new vhost-user driver is registered after the trigger (think OVS-DPDK that could add a port dynamically from cmdline), the current code will effectively starts the session for the new driver just after the first API rte_vhost_driver_register() is invoked, leaving later calls taking no effect at all. To handle the case properly, this patch introduce a new API, rte_vhost_driver_start(path), to trigger a specific vhost-user driver. To do that, the rte_vhost_driver_register(path, flags) is simplified to create the socket only and let rte_vhost_driver_start(path) to actually put it into the session loop. Meanwhile, the rte_vhost_driver_session_start is removed: we could hide the session thread internally (create the thread if it has not been created). This would also simplify the application. NOTE: the API order in prog guide is slightly adjusted for showing the correct invoke order.

vhost: export guest memory regions Some vhost-user driver may need this info to setup its own page tables for GPA (guest physical addr) to HPA (host physical addr) translation. SPDK (Storage Performance Development Kit) is one example. Besides, by exporting this memory info, we could also export the gpa_to_vva() as an inline function, which helps for performance. Otherwise, it has to be referenced indirectly by a "vid". Signed-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com>

vhost: export the number of vrings We used to use rte_vhost_get_queue_num() for telling how many vrings. However, the return value is the number of "queue pairs", which is very virtio-net specific. To make it generic, we should return the number of vrings instead, and let the driver do the proper translation. Say, virtio-net driver could turn it to the number of queue pairs by dividing 2. Meanwhile, mark rte_vhost_get_queue_num as deprecated. Signed-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com>
