i want to determine maximum speed of cpu in MHz with linux operating system and MIPS hardware. With command cat /proc/cpuinfo it results in BogoMIPS=1000.00. And 

`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq`

is not working. How can i convert it into MHz.Or what unit is used for BogoMIPS?? Thanks in advance

Try this:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

or this:

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

There should be similar files for the minimum frequency as well.

The information should be under cpuinfo. What does it give you if you enter:

cat /proc/cpuinfo | grep Hz

  • Unfortunately, that won't give what the user is asking, as the speed listed under `/proc/cpuinfo` is the current speed, and may differ from the max speed if frequency scaling is in effect. – twalberg Apr 26 '13 at 14:27
