Enabling this option hinders debugging on some recent GDB versions
|
|
|
|
|
(because GDB gets "confused" when we do an execvp()). So probably you
|
|
|
|
|
should disable it.

This option enables a debugging interface which allows gdb to debug

the kernel without needing to actually attach to kernel threads.

If you want to do kernel debugging, say Y here; otherwise say N.
