Some distros (Ubuntu) ship the msr driver as a module. If turbosat is run as root on those systems, and discovers that there is no /dev/cpu/cpu0/msr, it will now "modprobe msr" for the user. If not root, the modprobe attempt will fail, and turbostat will exit as before: turbostat: no /dev/cpu/0/msr, Try "# modprobe msr" : No such file or directory Signed-off-by: Len Brown <len.brown@intel.com>
