General idea is that if we build hardware independent block, network
and other devices then maybe it makes sens to build hardware independent
timer/clock. As I know exiting hardware timers/clocks are quite difficult
to emulate properly in virtual environments. Most problems are solved
right now but maybe we should still consider addition of timer/clock spec
in new VIRTIO spec. This way we will make stable time source for virtual
guests without issues and limitations imposed by existing and new relevant
hardware devices.
