Currently, MSI messages can only be injected to in-kernel irqchips by defining a corresponding IRQ route for each message. This is not only unhandy if the MSI messages are generated "on the fly" by user space, IRQ routes are a limited resource that user space has to manage carefully. By providing a direct injection path, we can both avoid using up limited resources and simplify the necessary steps for user land.

operating systems inside virtual machines (guests).

This option alone does not add any kernel code.

If you say N, all options in this submenu will be skipped and disabled.

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.
