13 This option is selected by any driver which needs to access

35 tristate "Host kernel accelerator for virtio net"
36 depends on NET && EVENTFD && (TUN || !TUN) && (TAP || !TAP)
39 This kernel module can be loaded in host kernel to accelerate
40 guest networking with virtio_net. Not to be confused with virtio_net
41 module itself which needs to be loaded in guest kernel.
43 To compile this driver as a module, choose M here: the module will
47 tristate "VHOST_SCSI TCM fabric driver"
48 depends on TARGET_CORE && EVENTFD
52 Say M here to enable the vhost_scsi TCM fabric module
53 for use with virtio-scsi guests
56 tristate "vhost virtio-vsock driver"
57 depends on VSOCKETS && EVENTFD
59 select VIRTIO_VSOCKETS_COMMON
62 This kernel module can be loaded in the host kernel to provide AF_VSOCK
63 sockets for communicating with guests. The guests must have the
64 virtio_transport.ko driver loaded to use the virtio-vsock device.
66 To compile this driver as a module, choose M here: the module will be called
70 tristate "Vhost driver for vDPA-based backend"
73 select IRQ_BYPASS_MANAGER
76 This kernel module can be loaded in host kernel to accelerate
77 guest virtio devices with the vDPA-based backends.
79 To compile this driver as a module, choose M here: the module
80 will be called vhost_vdpa.
82 config VHOST_CROSS_ENDIAN_LEGACY
83 bool "Cross-endian support for vhost"
86 This option allows vhost to support guests with a different byte
87 ordering from host while using legacy virtio.
89 Userspace programs can control the feature using the
90 VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
92 This is only useful on a few platforms (ppc64 and arm64). Since it
93 adds some overhead, it is disabled by default.
