Managing and Developing Dynamically Loadable Kernel Modules

Managing Dynamically Loadable Kernel Modules

Chapter 12498

Module

Wrapper

The additional code and data structures added to a

kernel module which enable the DLKM

infrastructure to logically connect and disconnect a

loadable module to and from the running kernel.

Boot Time

The loading of a dynamically loadable kernel module

during the early phases of the system boot up process.

Supported

Phases

This is a static attribute associated with each DLKM

module that indicates when the module is capable of

being loaded. A DLKM module may indicate one or

more of the following supported loading phases:

phase 1 of the boot sequence (BOOT1), phase 2 of the

boot sequence (BOOT2), or runtime (RUN). Phase 1 and

phase 2 of the boot sequence are architecture-speciﬁc,

so the Supported Loading Phases are architecture-

speciﬁc also. Refer to “Developing Dynamically

Loadable Kernel Modules” on page 525 for more

details.
