13.3.1. Dynamically Loading/Unloading Your Kernel PlugIn Driver
If you used WinDriver to develop a Kernel PlugIn driver [11], you must load this driver only after loading
the generic WinDriver driver — windrvr6.o/.ko.
When unloading the drivers, unload your Kernel PlugIn driver before unloading
windrvr6.o/.ko.
Kernel PlugIn drivers are dynamically loadable — i.e., they can be
loaded and unloaded without reboot.
Use the following commands to dynamically
load or unload your Kernel PlugIn driver.

To dynamically load your Kernel PlugIn driver, run this command:
# /sbin/insmod <path to kp_xxx_module.o/.ko>

When building the Kernel PlugIn driver on the development machine, the
Kernel PlugIn driver module is created in your Kernel PlugIn
project's kermode/linux/LINUX.<kernel version>.<CPU> directory (see
Section 12.7.2, Step 4).
When building the driver on a target distribution machine, the driver
module is normally created in an
xxx_installation/redist/LINUX.<kernel version>.<CPU>.KP directory
(see Section 14.4.3, Step 2).

To dynamically unload your Kernel PlugIn, run this command:
# /sbin/rmmod kp_xxx_module

To automatically load your Kernel PlugIn driver on each boot,
add the following line to the target's Linux boot file (for example,
/etc/rc.local), after the WinDriver driver module
(windrvr6) load command (replace
<path to kp_xxx_module.o/.ko>
with the path to your Kernel PlugIn driver module):
/sbin/insmod <path to kp_xxx_module.o/.ko> |
