rdmsr
— Read
Model-Specific Register
rdmsr |
[0x<msrnr>]... |
The rdmsr
command can be used to read a
value out of one or more x86 MSRs, as defined by the Intel and AMD CPU
specifications. The integer MSR number should be given (typically in
0x-prefixed hexadecimal). It is the command-line equivalent of the
rdmsr
()
instruction).
The read is done on the current CPU, which may change arbitrarily between MSR reads: to read from a particular CPU, pbind(8) can be used to execute this utility.
The rdmsr
utility exits 0 on success, or 1
if an error occurs, or at least one MSR could not be read.
