Sure. Just poke if you have something to inspect or look at because of
$reason.

The architectures, that support RT are what you see in
| git grep ARCH_SUPPORTS_RT arch/

so this does not include arm at current stage for instance. So in
general, if you can't select CONFIG_PREEMPT_RT you can skip the
config/ build/ test.

RiscV on the other hand is supported.

Sure. How do I see easily what is tested/ done? I could maybe wait a few
days and check the dashboard. The link from above showed timerlat has
been but I didn't manage to figure what has been. I guess there is a
script somewhere handling the logic.
