NAME

SYNOPSIS

DESCRIPTION

OPTIONS

-a, --all

Show information for all MSRs known to the tool for that CPU family.

-c cpu_nr, --cpu cpu_nr

Select CPU (by number) for which MSR information should be displayed (default: 0).

-f fam, --family fam

Specify CPU family. Normally CPU family is auto-detected. You can use this option to disable auto-detection, e.g. for debugging purposes.

-l, --list

Show definition (address, field description) of selected MSR(s).

-r name|address, --register name|address

Specify MSR (by name or address in hex) for which MSR information should be displayed.

-V num, --verbosity num

Select verbosity of output format (between 0 and 4, default: 0)

-h, --help

Print help message and exit.

-v, --version

Display version info and exit.

Examples

Show all MSRs beginning with 'MTRR' and force CPU family to 0x10
