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