files, and the config (1M) manpage for a description of the HP-UX system
file.
Advantages of DLKM Drivers
DLKM drivers/modules provide many advantages relative to static
drivers/modules, including:
• making it easier for administrators to install device drivers from
other vendors
• improving system availability by allowing device drivers and other
modules to be configured into the kernel while the system is running
• conserving system resources by unloading infrequently used modules
when not in use
• providing administrators with the ability to demand load and unload
modules
• providing the kernel with the ability to automatically load modules
Auto loading occurs when the kernel detects a particular loadable
module is required to accomplish some task, but the module is not
currently loaded. The kernel automatically loads the module.
NOTE Auto unloading is not supported in HP-UX 11.0.
