Loadable Module
(DLKM Module)
A Loadable Module (or DLKM Module) is a Modularly packaged
Module with the capability to be dynamically loaded into a running
kernel.
In the kernel configuration context, this means that the DLKM
module uses its own master and system files and contains the
module wrapper code and additional data structures that provide
the dynamic loading and unloading ability.
However, when a DLKM module is written with self-contained
module wrapper code and packaged with module-specific master
and system files, it can still be statically configured into the kernel.
For this reason, we place Loadable Modules in two categories:
• Statically Configured Loadable Module
• Dynamically Configured Loadable Module
Statically
Configured
Loadable Module
A Statically configured Loadable Module is a DLKM module that
has the capability to be dynamically loaded but instead is
configured to be statically built into the kernel.
In the kernel configuration context, this means that the
module-specific system file was updated to indicate static
configuration.
Because it is now statically built into the kernel, it cannot be
unloaded from or reloaded into loaded into the kernel dynamically.
