/proc/cpuinfo not showing all info

[Pankaj Vinodrao Joshi]

i agree each processor type exports different information but i need to pop up information while i do /proc/cpu also i have observed that almost every arch display information w.r.t frequency. Can you suggest how i can add info related to cpufreq into /proc ?



Thanks

Each processor type exports different information in /proc/cpuinfo.  How
would a riscv cpu have the same types as an x86 cpu?

You have to treat each cpu type individually, there is no common format
for all different CPUs out there, sorry.

Hope this helps,
