1config VHOST_NET
2	tristate "Host kernel accelerator for virtio net"
3	depends on NET && EVENTFD && (TUN || !TUN) && (TAP || !TAP)
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
13config VHOST_SCSI
14	tristate "VHOST_SCSI TCM fabric driver"
15	depends on TARGET_CORE && EVENTFD
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
22config 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
36config VHOST
37	tristate
38	---help---
39	  This option is selected by any driver which needs to access
40	  the core of vhost.
41
42config 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".
