Hi, where is the CPU located and mounted on the Linux file system? For example, a mouse is at /dev/psaux, where is the cpu located in /dev/ ? Thanks

I don't think the cpu is a device that you can mount and unmount. I could be wrong on this though.

The cpu is not a device you can directly read/write data like the mouse, so it is not in /dev, you can find some info on your cpu in /proc/cpuinfo

Code:

# find /dev -iname '*cpu*'
# find /proc -iname '*cpu*'
/proc/sys/vm/percpu_pagelist_fraction
/proc/cpuinfo

If your kernel (and udev) is setup correctly, you can access /dev/cpu/microcode, /dev/cpu/*/msr, and /dev/cpu/*/cpuid.
