So is there some userspace part to go with this now?FWIW I've not looked into it - is it just a case of someone knocking out some JSON from the MMU-600/700 TRMs, or is there still mroe to do?
That should just be it.
I had the impression that *some* part of the process was stalled until implementations can start providing meaningful IIDRs, but I wasn't sure whether that was tooling or just data. I just work the low-level enablement angle :)
Tooling should be ok, but I would just like to see more of these JSONs so any tooling issues can be ironed out. Cheers, John _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
