.SH NAME
msr \- x86 CPU MSR access device
.SH DESCRIPTION
.I /dev/cpu/CPUNUM/msr
allows to read and write the model specific registers (MSRs) of an x86 CPU.
.I CPUNUM 
is the number of the cpu to access as listed in 
.I /proc/cpuinfo.
The register access is done by opening the file and seeking to the MSR number
as offset in the file and then read or write in chunks of 8 bytes.
A larger size than 8 bytes means multiple reads or writes of the 
same register.
.SH NOTES
The 
.I msr
driver is not auto-loaded. On modular kernel you might need to use
.B modprobe msr
to load it explicitely before use.
