This document may not be entirely up to date and comprehensive. The command
|
2020-03-02 08:16:05 +00:00
|
|
|
``modinfo -p ${modulename}`` shows a current list of all parameters of a loadable
|
2010-08-14 19:36:14 +00:00
|
|
|
module. Loadable modules, after being loaded into the running kernel, also
|
|
|
|
|
reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
|
|
|
|
|
parameters may be changed at runtime by the command
|
2020-03-02 08:16:05 +00:00
|
|
|
``echo -n ${value} > /sys/module/${modulename}/parameters/${parm}``.
