Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

config VHOST_IOTLB
	tristate
	help
	  Generic IOTLB implementation for vhost and vringh.
	  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.

menuconfig VHOST_MENU

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.
