This option is selected by any driver which needs to support an IOMMU in software.
config VHOST_RING tristate select VHOST_IOTLB help This option is selected by any driver which needs to access the host side of a virtio ring.
config VHOST_TASK bool default n
config VHOST tristate select VHOST_IOTLB select VHOST_TASK help This option is selected by any driver which needs to access the core of vhost.

config VHOST_NET tristate "Host kernel accelerator for virtio net" depends on NET && EVENTFD && (TUN || !TUN) && (TAP || !TAP) select VHOST help This kernel module can be loaded in host kernel to accelerate guest networking with virtio_net. Not to be confused with virtio_net module itself which needs to be loaded in guest kernel.
To compile this driver as a module, choose M here: the module will be called vhost_net.
config VHOST_SCSI tristate "VHOST_SCSI TCM fabric driver" depends on TARGET_CORE && EVENTFD select VHOST select SG_POOL default n help Say M here to enable the vhost_scsi TCM fabric module for use with virtio-scsi guests
config VHOST_VSOCK tristate "vhost virtio-vsock driver" depends on VSOCKETS && EVENTFD select VHOST select VIRTIO_VSOCKETS_COMMON default n help This kernel module can be loaded in the host kernel to provide AF_VSOCK sockets for communicating with guests. The guests must have the virtio_transport.ko driver loaded to use the virtio-vsock device.
To compile this driver as a module, choose M here: the module will be called vhost_vsock.
config VHOST_VDPA tristate "Vhost driver for vDPA-based backend" depends on EVENTFD select VHOST select IRQ_BYPASS_MANAGER depends on VDPA help This kernel module can be loaded in host kernel to accelerate guest virtio devices with the vDPA-based backends.
To compile this driver as a module, choose M here: the module will be called vhost_vdpa.
config VHOST_CROSS_ENDIAN_LEGACY bool "Cross-endian support for vhost" default n help This option allows vhost to support guests with a different byte ordering from host while using legacy virtio.
Userspace programs can control the feature using the VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
This is only useful on a few platforms (ppc64 and arm64). Since it adds some overhead, it is disabled by default.
If unsure, say "N".
config VHOST_ENABLE_FORK_OWNER_CONTROL bool "Enable VHOST_ENABLE_FORK_OWNER_CONTROL" default y help This option enables two IOCTLs: VHOST_SET_FORK_FROM_OWNER and VHOST_GET_FORK_FROM_OWNER. These allow userspace applications to modify the vhost worker mode for vhost devices.
Also expose module parameter 'fork_from_owner_default' to allow users to configure the default mode for vhost workers.
By default, `VHOST_ENABLE_FORK_OWNER_CONTROL` is set to `y`, users can change the worker thread mode as needed. If this config is disabled (n),the related IOCTLs and parameters will be unavailable.
If unsure, say "Y".
