红帽全球峰会3.6. Loading kernel modules at system runtime
The optimal way to expand the functionality of the Linux kernel is by loading kernel modules. Use the modprobe command to find and load a kernel module into the currently running kernel.
The changes described in this procedure will not persist after rebooting the system. For information about how to load kernel modules to persist across system reboots, see Loading kernel modules automatically at system boot time.
Prerequisites
- You have root permissions on the system.
-
The
kmodpackage is installed. - The corresponding kernel module is not loaded. To ensure this, list the Listing currently loaded kernel modules.
Procedure
Select a kernel module you want to load.
The modules are located in the
/lib/modules/$(uname -r)/kernel/<SUBSYSTEM>/directory.Load the relevant kernel module:
# modprobe <MODULE_NAME>注意When entering the name of a kernel module, do not append the
.ko.xzextension to the end of the name. Kernel module names do not have extensions; their corresponding files do.
Verification
Optionally, verify the relevant module is loaded:
$ lsmod | grep <MODULE_NAME>If the module is loaded correctly, you can display it:
$ lsmod | grep serio_raw serio_raw 16384 0See the
modprobe(8)man page on your system for more information.
