Increase the annotation level. An annotation level of 1 features the historical -fullname option of gdb(1). This is useful when running kgdb in Emacs. The -f or -fullname options are supported for backward compatibility as well.
-q
Suppress printing of the banner when the debugger starts. The -quiet form is supported for compatibility as well.
-v
Increase verbosity.
-d crashdir
Use crashdir instead of the default, /var/crash to locate kernel core dump files in. The name vmcore. plus the dump number will be appended to determine the actual dump file name.
-c core
Explicitly use core as the core dump file.
-n dumpnr
Use the kernel core dump file numbered dumpnr for debugging.
-r device
Use device to connect kgdb to for a remote debugging session.
The -c -, -n , and -r options are mutually exclusive.
Optionally, the name of the kernel symbol file and the name of the core dump file can be supplied on the command-line as positional arguments. If no kernel symbol file name has been given, the symbol file of the currently running kernel will be used. If no core dump file has been specified through either of the options or the last command-line argument, /dev/mem will be opened to allow debugging the currently running kernel.
