File Content: Kconfig # SPDX-License-Identifier: GPL-2.0-only 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 tristate select VHOST_IOTLB help This option is selected by any driver which needs to access the core of vhost. menuconfig VHOST_MENU bool "VHOST drivers" default y if 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 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". endif Submit
