Currently, the IRQFD code is conditional on CONFIG_HAVE_KVM_IRQ_ROUTING. So that we can have the IRQFD code compiled in without having the IRQ routing code, this creates a new CONFIG_HAVE_KVM_IRQFD, makes the IRQFD code conditional on it instead of CONFIG_HAVE_KVM_IRQ_ROUTING, and makes all the platforms that currently select HAVE_KVM_IRQ_ROUTING also select HAVE_KVM_IRQFD.

This option alone does not add any kernel code.

Support hosting fully virtualized guest machines using hardware
|
|
virtualization extensions. You will need a fairly recent
|
|
processor equipped with virtualization extensions. You will also
|
|
need to select one or more of the processor modules below.
|
|
|
|
This module provides access to the hardware capabilities through
|
|
a character device node named /dev/kvm.
|
|
|
|
To compile this as a module, choose M here: the module
|
|
will be called kvm.

If unsure, say N.

Provide support for legacy PCI device assignment through KVM. The

kernel now also supports a full featured userspace device driver
|
|
framework through VFIO, which supersedes much of this support.
|
