+config VIRTIO
+ tristate
+ ---help---
+ This option is selected by any driver which implements the virtio
+ bus, such as CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_MMIO, CONFIG_RPMSG
+ or CONFIG_S390_GUEST.
+
+menuconfig VIRTIO_MENU
+ bool "Virtio drivers"
+ default y

+config VIRTIO_PCI
+ tristate "PCI driver for virtio devices"
+ depends on PCI
+ select VIRTIO
+ ---help---
+ This driver provides support for virtio based paravirtual device
+ drivers over PCI. This requires that your VMM has appropriate PCI
+ virtio backends. Most QEMU based VMMs should support these devices
+ (like KVM or Xen).
+
+ If unsure, say M.
+
+config VIRTIO_PCI_LEGACY
+ bool "Support for legacy virtio draft 0.9.X and older devices"
+ default y
+ depends on VIRTIO_PCI
+ ---help---
+ Virtio PCI Card 0.9.X Draft (circa 2014) and older device support.
+
+ This option enables building a transitional driver, supporting
+ both devices conforming to Virtio 1 specification, and legacy devices.
+ If disabled, you get a slightly smaller, non-transitional driver,
+ with no legacy compatibility.
+
+ So look out into your driveway. Do you have a flying car? If
+ so, you can happily disable this option and virtio will not
+ break. Otherwise, leave it set. Unless you're testing what
+ life will be like in The Future.
+
+ If unsure, say Y.
+
+config VIRTIO_BALLOON
+ tristate "Virtio balloon driver"
+ depends on VIRTIO
+ select MEMORY_BALLOON
+ ---help---
+ This driver supports increasing and decreasing the amount
+ of memory within a KVM guest.
+
+ If unsure, say M.
+
+config VIRTIO_INPUT
+ tristate "Virtio input driver"
+ depends on VIRTIO
+ depends on INPUT
+ ---help---
+ This driver supports virtio input devices such as
+ keyboards, mice and tablets.
+
+ If unsure, say M.
+
+ config VIRTIO_MMIO
+ tristate "Platform bus driver for memory mapped virtio devices"
+ depends on HAS_IOMEM && HAS_DMA
+ select VIRTIO
+ ---help---
+ This drivers provides support for memory mapped virtio
+ platform device driver.
+
+ If unsure, say N.
+
+config VIRTIO_MMIO_CMDLINE_DEVICES
+ bool "Memory mapped virtio devices parameter parsing"
+ depends on VIRTIO_MMIO
+ ---help---
+ Allow virtio-mmio devices instantiation via the kernel command line
+ or module parameters. Be aware that using incorrect parameters (base
+ address in particular) can crash your system - you have been warned.
+ See Documentation/admin-guide/kernel-parameters.rst for details.
+
+ If unsure, say 'N'.
