Is there an arm-msr-tools or similar that has setuid so we can access the MSRs?
I'm not familiar with any such tool, but I haven't looked for one before. I found an x86 msr-tools project at github with a web search. It seems to be a standard part of debian/ubuntu x86 distros. I don't see an obvious arm equivalent.
You could ask the kernel developers to add a hardware capability (hwcap) check for half-precision fp and emit that info into the /proc/cpuinfo file, though it would take a while for that to be implemented and propagate to your users.
