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
18 # RMK wants arm kernels compiled with frame pointers or stack unwinding.
19 # If you know what you are doing and are willing to live without stack
20 # traces, you can get a slightly smaller kernel by setting this option to
21 # n, but then RMK will have to kill you ;).
24 depends on !THUMB2_KERNEL
25 default y if !ARM_UNWIND || FUNCTION_GRAPH_TRACER
27 If you say N here, the resulting kernel will be slightly smaller and
28 faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
29 when a problem occurs with the kernel, the information that is
30 reported is severely limited.
33 bool "Enable stack unwinding support (EXPERIMENTAL)"
37 This option enables stack unwinding support in the kernel
38 using the information automatically generated by the
39 compiler. The resulting kernel image is slightly bigger but
40 the performance is not affected. Currently, this feature
41 only works with EABI compilers. If unsure say Y.
45 depends on FUNCTION_TRACER && FRAME_POINTER
49 bool "Verbose user fault messages"
51 When a user program crashes due to an exception, the kernel can
52 print a brief message explaining what the problem was. This is
53 sometimes helpful for debugging but serves no purpose on a
54 production system. Most people should say N here.
56 In addition, you need to pass user_debug=N on the kernel command
57 line to enable this feature. N consists of the sum of:
59 1 - undefined instruction events
61 4 - invalid data aborts
65 # These options are only for real kernel hackers who want to get their hands dirty.

70 Say Y here to include definitions of printascii, printch, printhex
71 in the kernel. This is helpful if you are debugging code that
72 executes before the console is initialized.
74 Note that selecting this option will limit the kernel to a single
75 UART definition, as specified below. Attempting to boot the kernel
76 image on a different platform *will not work*, so this option should
77 not be enabled for kernels that are intended to be portable.

1671 decompressor output because it is not possible to know where to
1672 send the decompressor output.
1674 When this option is set, the selected DEBUG_LL output method
1675 will be re-used for normal decompressor output on multiplatform
1679 config UNCOMPRESS_INCLUDE
1681 default "debug/uncompress.h" if ARCH_MULTIPLATFORM || ARCH_MSM || \
1682 PLAT_SAMSUNG || ARM_SINGLE_ARMV7M
1683 default "mach/uncompress.h"
1689 Say Y here if you want to have an early console using the
1690 kernel low-level debugging functions. Add earlyprintk to your
1691 kernel parameters to enable this console.
1693 config ARM_KPROBES_TEST
1694 tristate "Kprobes test module"
1695 depends on KPROBES && MODULES
1697 Perform tests of kprobes API and instruction set simulation.
1699 config PID_IN_CONTEXTIDR
1700 bool "Write the current PID to the CONTEXTIDR register"
1701 depends on CPU_COPY_V6
1703 Enabling this option causes the kernel to write the current PID to
1704 the PROCID field of the CONTEXTIDR register, at the expense of some
1705 additional instructions during context switch. Say Y here only if you
1706 are planning to use hardware trace tools with this kernel.
1708 config DEBUG_SET_MODULE_RONX
1709 bool "Set loadable kernel module data as NX and text as RO"
1710 depends on MODULES && MMU
1712 This option helps catch unintended modifications to loadable
1713 kernel module's text and read-only data. It also prevents execution
1714 of module data. Such protection may interfere with run-time code
1715 patching and dynamic kernel tracing - and they might also protect
1716 against certain classes of kernel exploits.
1717 If in doubt, say "N".
