Chapter 8

Kernel Debugging Modules

This chapter describes the debugger modules, dcmds, and walkers provided to debug the Solaris kernel. Each kernel debugger module is named after the corresponding Solaris kernel module, so that it will be loaded automatically by MDB. The facilities described here reflect the current Solaris kernel implementation and are subject to change in the future; writing shell scripts that depend on the output of these commands is not recommended. In general, the kernel debugging facilities described in this chapter are meaningful only in the context of the corresponding kernel subsystem implementation. See Related Books and Papers for a list of references that provide more information about the Solaris kernel implementation.

Note - MDB exposes kernel implementation details that are subject to change at any time. This guide reflects the Solaris kernel implementation as of the date of publication of this guide. Information provided in this guide about modules, dcmds, walkers, and their output formats and arguments might not be correct or applicable to past or future Solaris releases.
