5 Generic IOTLB implementation for vhost and vringh.
11 This option is selected by any driver which needs to access
12 the host side of a virtio ring.
18 This option is selected by any driver which needs to access
28 tristate "Host kernel accelerator for virtio net"
29 depends on NET && EVENTFD && (TUN || !TUN) && (TAP || !TAP)
32 This kernel module can be loaded in host kernel to accelerate
33 guest networking with virtio_net. Not to be confused with virtio_net
34 module itself which needs to be loaded in guest kernel.
36 To compile this driver as a module, choose M here: the module will
40 tristate "VHOST_SCSI TCM fabric driver"
41 depends on TARGET_CORE && EVENTFD
45 Say M here to enable the vhost_scsi TCM fabric module
46 for use with virtio-scsi guests
49 tristate "vhost virtio-vsock driver"
50 depends on VSOCKETS && EVENTFD
52 select VIRTIO_VSOCKETS_COMMON
55 This kernel module can be loaded in the host kernel to provide AF_VSOCK
56 sockets for communicating with guests. The guests must have the
57 virtio_transport.ko driver loaded to use the virtio-vsock device.
59 To compile this driver as a module, choose M here: the module will be called
63 tristate "Vhost driver for vDPA-based backend"
68 This kernel module can be loaded in host kernel to accelerate
69 guest virtio devices with the vDPA-based backends.
71 To compile this driver as a module, choose M here: the module
72 will be called vhost_vdpa.
74 config VHOST_CROSS_ENDIAN_LEGACY
75 bool "Cross-endian support for vhost"
78 This option allows vhost to support guests with a different byte
79 ordering from host while using legacy virtio.
81 Userspace programs can control the feature using the
82 VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
84 This is only useful on a few platforms (ppc64 and arm64). Since it
85 adds some overhead, it is disabled by default.
