If extensions aren't usable, they shouldn't be in /proc/cpuinfo either as there's programs that parse that to figure out what they can use, possibly even only checking a single cpu and using that as gospel. That's why there's that per-hart-isa thing that was added by one of your colleagues last year. [unhandled content-type:application/pgp-signature] | |
