I believe so. We should probably have smokey accept a --vm option or
something along, to tell it about a virtual execution environment, which
may be freely interpreted by any test code concerned, e.g. to figure out
whether timings might be inaccurate due to a significant slowdown. We
could likely figure this out automatically, but I'd rather leave this
decision to the user. I'll have a look at this asap.

I will open dedicated arm64 branches tomorrow into the project
repositories for both the ipipe and xenomai, that could be merged to the
corresponding mainline branches when ready for prime time. The target
would be Xenomai 3.1, it's too late for bringing this in 3.0-rc.

So the process should be fairly common and straightforward: a pull
request from your end for code present in your repo would trigger the
review, bits getting merged gradually from your repo to the dedicated
arm64 branches, along with other contributions, until we can all declare
these branches ready for mainline.
