+config VHOST_IOTLB
+ tristate
+ help
+ Generic IOTLB implementation for vhost and vringh.
+ This option is selected by any driver which needs to support
+ an IOMMU in software.
+
+config VHOST_RING
+ tristate
+ select VHOST_IOTLB
+ help
+ This option is selected by any driver which needs to access
+ the host side of a virtio ring.
+
+config VHOST
+ tristate
+ select VHOST_IOTLB
+ help
+ This option is selected by any driver which needs to access
+ the core of vhost.

+config VHOST_NET
+ tristate "Host kernel accelerator for virtio net"
+ depends on NET && EVENTFD && (TUN || !TUN) && (TAP || !TAP)
+ select VHOST
+ help
+ This kernel module can be loaded in host kernel to accelerate
+ guest networking with virtio_net. 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.

+ 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.

+ This kernel module can be loaded in host kernel to accelerate
+ guest virtio devices with the vDPA-based backends.
+
+ To compile this driver as a module, choose M here: the module
+ will be called vhost_vdpa.
+
+config VHOST_CROSS_ENDIAN_LEGACY
+ bool "Cross-endian support for vhost"
+ default n
+ help
+ This option allows vhost to support guests with a different byte
+ ordering from host while using legacy virtio.
+
+ 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".
