A while back QEMU introduced a new machine property for disabling the
i8042 PS/2 controller (commit 4ccd5fe22feb95137d325f422016a6473541fe9f)
which up until then was a built-in device included by all PC machine
type descendants unconditionally. This new option allowed users to
disable emulation of this controller, thus removing the default PS/2
peripherals. The rationale for why somebody might want to disable
PS/2 peripherals is explained in the aforementioned commit. This series
of patches exposes this machine property via the 'ps2' feature, while
also taking care of side-effects, such as inhibiting the implicit
creation of PS/2 inputs in the domain XML.
Changelog:
v2 -> v3:
- Add missing example usage of the new feature
v1 -> v2:
- Use abstract 'generic-pc' machine type instead of concrete 'pc' for
property detection
- Introduce test cases along with monitor replies and capability
flags
- Add NEWS mention of the new feature
