6 bool "Export kernel pagetable layout to userspace via debugfs"
7 depends on DEBUG_KERNEL
10 Say Y here if you want to show the kernel pagetable layout in a
11 debugfs file. This information is only useful for kernel developers
12 who are working in architecture specific areas of the kernel.
13 It is probably not a good idea to enable this feature in a production
18 bool "Filter access to /dev/mem"
21 If this option is disabled, you allow userspace (root) access to all
22 of memory, including kernel and userspace memory. Accidental
23 access to this is obviously disastrous, but specific access can
24 be used by people debugging the kernel.
26 If this option is switched on, the /dev/mem file only allows
27 userspace access to memory mapped peripherals.
31 # RMK wants arm kernels compiled with frame pointers or stack unwinding.
32 # If you know what you are doing and are willing to live without stack
33 # traces, you can get a slightly smaller kernel by setting this option to
34 # n, but then RMK will have to kill you ;).
37 depends on !THUMB2_KERNEL
38 default y if !ARM_UNWIND || FUNCTION_GRAPH_TRACER
40 If you say N here, the resulting kernel will be slightly smaller and
41 faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
42 when a problem occurs with the kernel, the information that is
43 reported is severely limited.
46 bool "Enable stack unwinding support (EXPERIMENTAL)"
50 This option enables stack unwinding support in the kernel
51 using the information automatically generated by the
52 compiler. The resulting kernel image is slightly bigger but
53 the performance is not affected. Currently, this feature
54 only works with EABI compilers. If unsure say Y.
58 depends on FUNCTION_TRACER && FRAME_POINTER
62 bool "Verbose user fault messages"
64 When a user program crashes due to an exception, the kernel can
65 print a brief message explaining what the problem was. This is
66 sometimes helpful for debugging but serves no purpose on a
67 production system. Most people should say N here.
69 In addition, you need to pass user_debug=N on the kernel command
70 line to enable this feature. N consists of the sum of:
72 1 - undefined instruction events
74 4 - invalid data aborts
78 # These options are only for real kernel hackers who want to get their hands dirty.
80 bool "Kernel low-level debugging functions (read help!)"
81 depends on DEBUG_KERNEL
83 Say Y here to include definitions of printascii, printch, printhex
84 in the kernel. This is helpful if you are debugging code that
85 executes before the console is initialized.
87 Note that selecting this option will limit the kernel to a single
88 UART definition, as specified below. Attempting to boot the kernel
89 image on a different platform *will not work*, so this option should
90 not be enabled for kernels that are intended to be portable.

1546 This option influences the normal decompressor output for

1548 decompressor output because it is not possible to know where to
1549 send the decompressor output.

1581 Enabling this option causes the kernel to write the current PID to

1590 This option helps catch unintended modifications to loadable
1591 kernel module's text and read-only data. It also prevents execution
1592 of module data. Such protection may interfere with run-time code
1593 patching and dynamic kernel tracing - and they might also protect
1594 against certain classes of kernel exploits.
1595 If in doubt, say "N".
