I do wonder when all those tools which just parse /proc/cpuinfo will finally die. Most of time new architecture comes and one of those breaks. Sometimes it is even build dependency for something else ;( There is /sys/devices/system/cpu/ which can provide more data. There is cpufreq subsystem which can give cpu frequencies. Check 'lscpu' tool which does even more than your linuxinfo. > It would be kind if you could check on aarch64 [2] if linuxinfo works > and produces sensible output.

Looks like each new architecture is just copy/paste of other + some changes. Rewrite which would parse /proc/cpuinfo in unified way nevermind which architecture would be better (if you insist on having such useless tool). There is Sys-CPU module for Perl which does the same and we also had to patch for AArch64 in past. Maybe will need to do the same again when format of /proc/cpuinfo will change again. > If you see any problems, bugs or replies to this e-mail > (including a description and /proc/cpuinfo) would be very welcome.
