NAME

msrtool - Dumps chipset-specific MSR registers

SYNOPSIS

msrtool [-hvqrkl] [-c cpu] [-m system] [-t target ...] [-i addr=hi[:]lo] | [-s file] | [-d [:]file] | addr...

DESCRIPTION

Dumps chipset-specific MSR registers

OPTIONS

-h

Show this help text

-v

Be verbose

-q

Be quiet (overrides -v)

-r

Include [Reserved] values

-k

List all known systems and targets

-l

List MSRs and bit fields for current target(s) (-kl for ALL targets!)

-c

Access MSRs on the specified CPU, default=0

-m

Force a system, e.g: -m linux

-t

Force a target, can be used multiple times, e.g: -t geodelx -t cs5536

-i

Immediate mode

Decode hex addr=hi:lo for the target without reading hw value
e.g: -i 4c00000f=f2f100ff56960004

-s

Stream mode


Read one MSR address per line and append current hw value to the line
use the filename - for stdin/stdout
using -l -s ignores input and will output all MSRs with values

-d

Diff mode


read one address and value per line and compare with current hw value, printing differences to stdout.
use the filename - to read from stdin
use :file or :- to reverse diff, normally hw values are considered new
addr.. direct mode, read and decode values for the given MSR address(es)
