| |
The virtio configuration options are inconsistent. According to this, every options that needs virtio will select it:
# Virtio always gets selected by whoever wants it. config VIRTIO tristate
Note that it's not user-selectable, so any config file that tries to set it will be ignored when kconfig loads those options. And yet we have a whole set of options that depend on VIRTIO, like VIRTIO_CONSOLE for example. This makes it impossible to have VIRTIO_PCI modular and VIRTIO_CONSOLE built-in on x86_64, because:
1. VIRTIO_PCI selects VIRTIO and sets it to M 2. VIRTIO_CONSOLE gets forced to M because one of its dependencies is M
So either VIRTIO (and VIRTIO_RING) need to be user-selectable, or all of the options that depend on VIRTIO need to be changed to select it instead.
(For even more fun, LGUEST_GUEST on i386 forces VIRTIO, VIRTIO_RING and VIRTIO_CONSOLE all to Y.)
