RDMSR(8) Maintenance Procedures RDMSR(8)

NAME


rdmsr - Read Model-Specific Register

SYNOPSIS


rdmsr [0x<msrnr>]...

DESCRIPTION


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.

EXIT STATUS


The rdmsr utility exits 0 on success, or 1 if an error occurs, or at least
one MSR could not be read.
