Not to be confused with virtio_net	  module itself which needs to be loaded in guest kernel. 	  To compile this driver as a module, choose M here: the module will	  be called vhost_net. config VHOST_SCSI	tristate "VHOST_SCSI TCM fabric driver"	depends on TARGET_CORE && EVENTFD	select VHOST	select SG_POOL	default n	help	Say M here to enable the vhost_scsi TCM fabric module	for use with virtio-scsi guests config VHOST_VSOCK	tristate "vhost virtio-vsock driver"	depends on VSOCKETS && EVENTFD	select VHOST	select VIRTIO_VSOCKETS_COMMON	default n	help	This kernel module can be loaded in the host kernel to provide AF_VSOCK	sockets for communicating with guests.  The guests must have the	virtio_transport.ko driver loaded to use the virtio-vsock device. 	To compile this driver as a module, choose M here: the module will be called	vhost_vsock. config VHOST_VDPA	tristate "Vhost driver for vDPA-based backend"	depends on EVENTFD	select VHOST	select IRQ_BYPASS_MANAGER	depends on VDPA	help	  This kernel module can be loaded in host kernel to accelerate	  guest virtio devices with the vDPA-based backends.

Userspace programs can control the feature using the	  VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls. 	  This is only useful on a few platforms (ppc64 and arm64). Since it	  adds some overhead, it is disabled by default. 	  If unsure, say "N". config VHOST_ENABLE_FORK_OWNER_CONTROL	bool "Enable VHOST_ENABLE_FORK_OWNER_CONTROL"	default y	help	  This option enables two IOCTLs: VHOST_SET_FORK_FROM_OWNER and	  VHOST_GET_FORK_FROM_OWNER. These allow userspace applications	  to modify the vhost worker mode for vhost devices. 	  Also expose module parameter 'fork_from_owner_default' to allow users	  to configure the default mode for vhost workers. 	  By default, `VHOST_ENABLE_FORK_OWNER_CONTROL` is set to `y`,	  users can change the worker thread mode as needed.	  If this config is disabled (n),the related IOCTLs and parameters will	  be unavailable. 	  If unsure, say "Y". endif
