| 2 | You need to be ROOT or use SUDO to execute MSRTOOL. |
| 3 | |
| 4 | Note that you need /dev/cpu/*/msr available to run msrtool in Linux. |
| 5 | |
| 6 | |
| 7 | syntax: msrtool [-hvqrkl] [-c cpu] [-m system] [-t target ...] |
| 8 | [-i addr=hi[:]lo] | [-s file] | [-d [:]file] | addr... |
| 9 | -h show this help text |
| 10 | -v be verbose |
| 11 | -q be quiet (overrides -v) |
| 12 | -r include [Reserved] values |
| 13 | -k list all known systems and targets |
| 14 | -l list MSRs and bit fields for current target(s) (-kl for ALL targets!) |
| 15 | -c access MSRs on the specified CPU, default=0 |
| 16 | -m force a system, e.g: -m linux |
| 17 | -t force a target, can be used multiple times, e.g: -t geodelx -t cs5536 |
| 18 | -i immediate mode |
| 19 | decode hex addr=hi:lo for the target without reading hw value |
| 20 | e.g: -i 4c00000f=f2f100ff56960004 |
| 21 | -s stream mode |
| 22 | read one MSR address per line and append current hw value to the line |
| 23 | use the filename - for stdin/stdout |
| 24 | using -l -s ignores input and will output all MSRs with values |
| 25 | -d diff mode |
| 26 | read one address and value per line and compare with current hw value, |
| 27 | printing differences to stdout. use the filename - to read from stdin |
| 28 | use :file or :- to reverse diff, normally hw values are considered new |
| 29 | addr.. direct mode, read and decode values for the given MSR address(es) |

| 32 | Examples: |
| 33 | |
| 34 | msrtool 0x20000018 |
| 35 | |
| 36 | ./msrtool 0x200000{18,19,1a,1b,1c,1d} 0x4c0000{0f,14} |
