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".
