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.
