Chapter 18. Specifying a Debugging Target
18.5. Kernel Object Display
Some targets support kernel object display. Using this facility, gdb communicates specially with the
underlying operating system and can display information about operating system-level objects such
as mutexes and other synchronization objects. Exactly which objects can be displayed is determined
on a per-OS basis.
Use the
set os
command to set the operating system. This tells gdb which kernel object display
module to initialize:
(gdb) set os cisco
If
set os
succeeds, gdb will display some information about the operating system, and will create
a new
info
command which can be used to query the target. The
info
command is named after the
operating system:
(gdb) info cisco
List of Cisco Kernel Objects
Object
Description
any
Any and all objects
Further subcommands can be used to query about particular objects known by the kernel.
There is currently no way to determine whether a given operating system is supported other than to
try it.
