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.

Say Y here to get to see options for using your Linux host to run other

operating systems inside virtual machines (guests).

This option alone does not add any kernel code.

Support hosting paravirtualized guest machines using the SIE
|
|
virtualization capability on the mainframe. This should work
|
|
on any 64bit machine.
|
|
|
|
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.
