NAME

rdmsr - tool for reading CPU machine specific registers (MSR)

SYNOPSIS

rdmsr [options] regno

DESCRIPTION

rdmsr is a tool used for reading 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 rdmsr not being able to open files in /dev/cpu/...
