NAME
       wrmsr - tool for writing CPU machine specific registers (MSR)

SYNOPSIS
       wrmsr [options] regno value

DESCRIPTION
       wrmsr  is  a  tool  used for writing values to a CPU's machine specific
       registers (MSR).
       Note: if you're running a Debian kernel, be sure that the msr.ko kernel
       module is loaded. 'modprobe msr' should do the trick. Otherwise, you'll
       get an error about wrmsr not being able to open files in /dev/cpu/...
