Greg Edwards 84f3396b71 vhost: allow vhost-scsi driver to be built-in
It's useful to allow vhost-scsi to be built-in when testing vhost in L1
+ L2 VMs and booting L1 VM with QEMU '-kernel' option.

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.
config VHOST_SCSI
tristate "VHOST_SCSI TCM fabric driver"
depends on TARGET_CORE && EVENTFD
select VHOST
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 VIRTIO_VSOCKETS_COMMON
select VHOST
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
tristate
---help---
This option is selected by any driver which needs to access
the core of vhost.
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".
