2 ~~~~~~~~~~~~~~~~~~~~~~
3
4See Documentation/kernel-parameters.txt for general information on
5specifying module parameters.
6
7This document may not be entirely up to date and comprehensive. The command
8"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
9module. Loadable modules, after being loaded into the running kernel, also
10reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
11parameters may be changed at runtime by the command
12"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
