@node BSD libkvm Interface
@subsection BSD libkvm Interface
@cindex libkvm
@cindex kernel memory image
@cindex kernel crash dump
BSD-derived systems (FreeBSD/NetBSD/OpenBSD) have a kernel memory
interface that provides a uniform interface for accessing kernel virtual
memory images, including live systems and crash dumps. @value{GDBN}
uses this interface to allow you to debug live kernels and kernel crash
dumps on many native BSD configurations. This is implemented as a
special @code{kvm} debugging target. For debugging a live system, load
the currently running kernel into @value{GDBN} and connect to the
@code{kvm} target:
@smallexample
(@value{GDBP}) @b{target kvm}
@end smallexample
For debugging crash dumps, provide the file name of the crash dump as an
argument:
@smallexample
(@value{GDBP}) @b{target kvm /var/crash/bsd.0}
@end smallexample
Once connected to the @code{kvm} target, the following commands are
available:
@table @code
@kindex kvm
@item kvm pcb
Set current context from pcb address.
@item kvm proc
Set current context from proc address. This command isn't available on
modern FreeBSD systems.
@end table
