30 tristate "Host kernel accelerator for virtio net"
31 depends on NET && EVENTFD && (TUN || !TUN) && (TAP || !TAP)
34 This kernel module can be loaded in host kernel to accelerate
35 guest networking with virtio_net. Not to be confused with virtio_net
36 module itself which needs to be loaded in guest kernel.
38 To compile this driver as a module, choose M here: the module will
42 tristate "VHOST_SCSI TCM fabric driver"
43 depends on TARGET_CORE && EVENTFD
47 Say M here to enable the vhost_scsi TCM fabric module
48 for use with virtio-scsi guests
51 tristate "vhost virtio-vsock driver"
52 depends on VSOCKETS && EVENTFD
54 select VIRTIO_VSOCKETS_COMMON
57 This kernel module can be loaded in the host kernel to provide AF_VSOCK
58 sockets for communicating with guests. The guests must have the
59 virtio_transport.ko driver loaded to use the virtio-vsock device.
61 To compile this driver as a module, choose M here: the module will be called
65 tristate "Vhost driver for vDPA-based backend"
68 select IRQ_BYPASS_MANAGER
71 This kernel module can be loaded in host kernel to accelerate
72 guest virtio devices with the vDPA-based backends.
74 To compile this driver as a module, choose M here: the module
75 will be called vhost_vdpa.
77 config VHOST_CROSS_ENDIAN_LEGACY
78 bool "Cross-endian support for vhost"
81 This option allows vhost to support guests with a different byte
82 ordering from host while using legacy virtio.
84 Userspace programs can control the feature using the
85 VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
87 This is only useful on a few platforms (ppc64 and arm64). Since it
88 adds some overhead, it is disabled by default.
