1 | SCSI Kernel Parameters |
2 | ~~~~~~~~~~~~~~~~~~~~~~ | |
3 | ||
8c27ceff | 4 | See Documentation/admin-guide/kernel-parameters.rst for general information on |
163475fb RD |
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}". | |
