    DESCRIPTION

           /dev/cpu/CPUNUM/msr  provides an interface to read and write the model-
           specific registers (MSRs) of an x86 CPU.  CPUNUM is the number  of  the
           CPU to access as listed in /proc/cpuinfo.
    
           The  register access is done by opening the file and seeking to the MSR
           number as offset in the file, and then reading or writing in chunks  of
           8  bytes.  An I/O transfer of more than 8 bytes means multiple reads or
           writes of the same register.
    
           This file is protected so that it can be read and written only  by  the
           user root, or members of the group root.
    
    
    

    NOTES

           The  msr  driver is not auto-loaded.  On modular kernels you might need
           to use the following command to load it explicitly before use:
    
               $ modprobe msr
