Managing and Developing Dynamically Loadable Kernel Modules

Managing Dynamically Loadable Kernel Modules

Chapter 12 523

Call kmupdate after ﬁrst calling config. If you include the -u option in

the config invocation, there is no need to invoke kmupdate. The config

-u command automatically invokes kmupdate.

To update the kernel, execute the following kmupdate command:

/usr/sbin/kmupdate /stand/build/vmunix_test

Loading the Kernel

For a DLKM module conﬁgured as statically linked, use the -r option of

the shutdown (1M) command to load the newly generated kernel by

shutting down and rebooting the system. Executing the shutdown -r

command terminates all currently running processes and reboots the

system, which causes the new kernel conﬁguration to take effect. At that

time, all statically linked, dynamically conﬁgured modules associated

with the new kernel are accessible to the system.
