14 | ---help--- |
15 | This drivers provides support for virtio based paravirtual device | |
16 | drivers over PCI. 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. | |

49 | Allow virtio-mmio devices instantiation via the kernel command line | |
