6 Write kernel log output directly into the ocd or to a serial port.
8 This is useful for kernel debugging when your machine crashes very
9 early before the console code is initialized. For normal operation
10 it is not recommended because it looks ugly and doesn't cooperate
11 with klogd/syslogd or the X server. You should normally N here,
12 unless you want to debug such a crash.
14 # These options are only for real kernel hackers who want to get their hands dirty.
16 bool "Kernel low-level debugging functions"
17 depends on DEBUG_KERNEL
19 Say Y here to include definitions of printascii, printch, printhex
20 in the kernel. This is helpful if you are debugging code that
21 executes before the console is initialized.
24 bool "Kernel low-level debugging via On-Chip-Debugger"
28 Say Y here if you want the debug print routines to direct their
29 output to the UniCore On-Chip-Debugger channel using CP #1.
