5# RMK wants arm kernels compiled with frame pointers so hardwire this to y.
6# If you know what you are doing and are willing to live without stack
7# traces, you can get a slightly smaller kernel by setting this option to
8# n, but then RMK will have to kill you ;).
9config FRAME_POINTER
10 bool
11 default y
12 help
13 If you say N here, the resulting kernel will be slightly smaller and
14 faster. However, when a problem occurs with the kernel, the
15 information that is reported is severely limited. Most people
16 should say Y here.

18config DEBUG_USER
19 bool "Verbose user fault messages"
20 help
21 When a user program crashes due to an exception, the kernel can
22 print a brief message explaining what the problem was. This is
23 sometimes helpful for debugging but serves no purpose on a
24 production system. Most people should say N here.

26config DEBUG_WAITQ
27 bool "Wait queue debugging"

30config DEBUG_ERRORS
31 bool "Verbose kernel error messages"
32 depends on DEBUG_KERNEL
33 help
34 This option controls verbose debugging information which can be
35 printed when the kernel detects an internal error. This debugging
36 information is useful to kernel hackers when tracking down problems,
37 but mostly meaningless to other people. It's safe to say Y unless
38 you are concerned with the code size or don't want to see these
39 messages.

41# These options are only for real kernel hackers who want to get their hands dirty.
42config DEBUG_LL
43 bool "Kernel low-level debugging functions"
44 depends on DEBUG_KERNEL
45 help
46 Say Y here to include definitions of printascii, printchar, printhex
47 in the kernel. This is helpful if you are debugging code that
48 executes before the console is initialized.
