  1 config VHOST_NET
  2         tristate "Host kernel accelerator for virtio net"
  3         depends on NET && EVENTFD && (TUN || !TUN) && (MACVTAP || !MACVTAP)
  4         select VHOST
  5         ---help---
  6           This kernel module can be loaded in host kernel to accelerate
  7           guest networking with virtio_net. Not to be confused with virtio_net
  8           module itself which needs to be loaded in guest kernel.
  9 
 10           To compile this driver as a module, choose M here: the module will
 11           be called vhost_net.
 12 
 13 config VHOST_SCSI
 14         tristate "VHOST_SCSI TCM fabric driver"
 15         depends on TARGET_CORE && EVENTFD && m
 16         select VHOST
 17         default n
 18         ---help---
 19         Say M here to enable the vhost_scsi TCM fabric module
 20         for use with virtio-scsi guests
 21 
 22 config VHOST_VSOCK
 23         tristate "vhost virtio-vsock driver"
 24         depends on VSOCKETS && EVENTFD
 25         select VIRTIO_VSOCKETS_COMMON
 26         select VHOST
 27         default n
 28         ---help---
 29         This kernel module can be loaded in the host kernel to provide AF_VSOCK
 30         sockets for communicating with guests.  The guests must have the
 31         virtio_transport.ko driver loaded to use the virtio-vsock device.
 32 
 33         To compile this driver as a module, choose M here: the module will be called
 34         vhost_vsock.
 35 
 36 config VHOST
 37         tristate
 38         ---help---
 39           This option is selected by any driver which needs to access
 40           the core of vhost.
 41 
 42 config VHOST_CROSS_ENDIAN_LEGACY
 43         bool "Cross-endian support for vhost"
 44         default n
 45         ---help---
 46           This option allows vhost to support guests with a different byte
 47           ordering from host while using legacy virtio.
 48 
 49           Userspace programs can control the feature using the
 50           VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
 51 
 52           This is only useful on a few platforms (ppc64 and arm64). Since it
 53           adds some overhead, it is disabled by default.
 54 
 55           If unsure, say "N".
