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.

1674 depends on ARCH_MULTIPLATFORM || PLAT_SAMSUNG || ARM_SINGLE_ARMV7M
1675 default y if DEBUG_LL && !DEBUG_OMAP2PLUS_UART && \
1676 (!DEBUG_TEGRA_UART || !ZBOOT_ROM)
1678 This option influences the normal decompressor output for
1679 multiplatform kernels. Normally, multiplatform kernels disable
1680 decompressor output because it is not possible to know where to
1681 send the decompressor output.
1683 When this option is set, the selected DEBUG_LL output method
1684 will be re-used for normal decompressor output on multiplatform
1688 config UNCOMPRESS_INCLUDE
1690 default "debug/uncompress.h" if ARCH_MULTIPLATFORM || ARCH_MSM || \
1691 PLAT_SAMSUNG || ARM_SINGLE_ARMV7M
1692 default "mach/uncompress.h"
1698 Say Y here if you want to have an early console using the
1699 kernel low-level debugging functions. Add earlyprintk to your
1700 kernel parameters to enable this console.
1702 config ARM_KPROBES_TEST
1703 tristate "Kprobes test module"
1704 depends on KPROBES && MODULES
1706 Perform tests of kprobes API and instruction set simulation.
1708 config PID_IN_CONTEXTIDR
1709 bool "Write the current PID to the CONTEXTIDR register"
1710 depends on CPU_COPY_V6
1712 Enabling this option causes the kernel to write the current PID to
1713 the PROCID field of the CONTEXTIDR register, at the expense of some
1714 additional instructions during context switch. Say Y here only if you
1715 are planning to use hardware trace tools with this kernel.
1717 config DEBUG_SET_MODULE_RONX
1718 bool "Set loadable kernel module data as NX and text as RO"
1719 depends on MODULES && MMU
1721 This option helps catch unintended modifications to loadable
1722 kernel module's text and read-only data. It also prevents execution
1723 of module data. Such protection may interfere with run-time code
1724 patching and dynamic kernel tracing - and they might also protect
1725 against certain classes of kernel exploits.
1726 If in doubt, say "N".
