Deciding if/how qemu can run binaries for each tuning target is
already partially addressed by the QEMU_EXTRAOPTIONS logic in
qemu.bbclass. My suggestion would be to somehow generalise that
existing logic, so (at least for machines using one of the standard
oe-core tuning files) the question "can qemu run binaries created for
${MACHINE}?" could be answered automatically.
I agree: machine features should specify the capabilities of a machine,
and 'generate of gobject introspection data' is only a specific
application of 'machine has qemu usermode support' feature. We might
have other uses for qemu userspace in the future, for example gtkdoc
generation.
So I'm thinking of having a machine feature called 'qemu-usermode',
which is turned on by default, and can be disabled in specific machine
configurations. And then a distro feature called 'gobject introspection
data', which is on or off depending on whether the machine supports it,
but can also be turned off explicitly. And then the recipes and recipe
classes do the right thing. How's that?
