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