This requires that your VMM has appropriate PCI 17 virtio backends. Most QEMU based VMMs should support these devices 18 (like KVM or Xen). 19 20 Currently, the ABI is not considered stable so there is no guarantee 21 that this version of the driver will work with your VMM. 22 23 If unsure, say M. 24 25config VIRTIO_BALLOON 26 tristate "Virtio balloon driver" 27 depends on VIRTIO 28 ---help--- 29 This driver supports increasing and decreasing the amount 30 of memory within a KVM guest. 31 32 If unsure, say M. 33 34 config VIRTIO_MMIO 35 tristate "Platform bus driver for memory mapped virtio devices (EXPERIMENTAL)" 36 depends on HAS_IOMEM && EXPERIMENTAL 37 select VIRTIO 38 ---help--- 39 This drivers provides support for memory mapped virtio 40 platform device driver. 41 42 If unsure, say N. 43 44config VIRTIO_MMIO_CMDLINE_DEVICES 45 bool "Memory mapped virtio devices parameter parsing" 46 depends on VIRTIO_MMIO 47 ---help--- 48 Allow virtio-mmio devices instantiation via the kernel command line 49 or module parameters.
