This patch adds an option to instantiate guest virtio-mmio devices basing on a kernel command line (or module) parameter, for example: virtio_mmio.devices=0x100@0x100b0000:48 Signed-off-by: Pawel Moll <pawel.moll@arm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

This drivers 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).
|
|
|
|
Currently, the ABI is not considered stable so there is no guarantee
|
|
that this version of the driver will work with your VMM.

If unsure, say M.

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.
