6 bool "Export kernel pagetable layout to userspace via debugfs"
7 depends on DEBUG_KERNEL
11 Say Y here if you want to show the kernel pagetable layout in a
12 debugfs file. This information is only useful for kernel developers
13 who are working in architecture specific areas of the kernel.
14 It is probably not a good idea to enable this feature in a production
19 bool "Filter access to /dev/mem"
22 If this option is disabled, you allow userspace (root) access to all
23 of memory, including kernel and userspace memory. Accidental
24 access to this is obviously disastrous, but specific access can
25 be used by people debugging the kernel.
27 If this option is switched on, the /dev/mem file only allows
28 userspace access to memory mapped peripherals.
32 # RMK wants arm kernels compiled with frame pointers or stack unwinding.
33 # If you know what you are doing and are willing to live without stack
34 # traces, you can get a slightly smaller kernel by setting this option to
35 # n, but then RMK will have to kill you ;).
38 depends on !THUMB2_KERNEL
39 default y if !ARM_UNWIND || FUNCTION_GRAPH_TRACER
41 If you say N here, the resulting kernel will be slightly smaller and
42 faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
43 when a problem occurs with the kernel, the information that is
44 reported is severely limited.
47 bool "Enable stack unwinding support (EXPERIMENTAL)"
51 This option enables stack unwinding support in the kernel
52 using the information automatically generated by the
53 compiler. The resulting kernel image is slightly bigger but
54 the performance is not affected. Currently, this feature
55 only works with EABI compilers. If unsure say Y.
59 depends on FUNCTION_TRACER && FRAME_POINTER
63 bool "Verbose user fault messages"
65 When a user program crashes due to an exception, the kernel can
66 print a brief message explaining what the problem was. This is
67 sometimes helpful for debugging but serves no purpose on a
68 production system. Most people should say N here.
70 In addition, you need to pass user_debug=N on the kernel command
71 line to enable this feature. N consists of the sum of:
73 1 - undefined instruction events
75 4 - invalid data aborts
79 # These options are only for real kernel hackers who want to get their hands dirty.
81 bool "Kernel low-level debugging functions (read help!)"
82 depends on DEBUG_KERNEL
84 Say Y here to include definitions of printascii, printch, printhex
85 in the kernel. This is helpful if you are debugging code that
86 executes before the console is initialized.
88 Note that selecting this option will limit the kernel to a single
89 UART definition, as specified below. Attempting to boot the kernel
90 image on a different platform *will not work*, so this option should
91 not be enabled for kernels that are intended to be portable.

1598 decompressor output because it is not possible to know where to
1599 send the decompressor output.

1642 of module data. Such protection may interfere with run-time code
1643 patching and dynamic kernel tracing - and they might also protect
1644 against certain classes of kernel exploits.
1645 If in doubt, say "N".
