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.
67 bool "Kernel low-level debugging functions (read help!)"
68 depends on DEBUG_KERNEL
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.

1301 their output to an UART or USART port on efm32 based
1302 machines. Use the following addresses for DEBUG_UART_PHYS:

1313 Say Y here if you wish the debug print routes to direct
1314 their output to a PL01x Primecell UART. You can use
1315 this option to provide the parameters for the UART
1316 rather than selecting one of the platform specific
1317 options above if you know the parameters for the port.

1695 Palmchip provides a UART implementation compatible with 16550
1696 except for having a different register layout. Say Y here if

1711 This option influences the normal decompressor output for
1712 multiplatform kernels. Normally, multiplatform kernels disable
1713 decompressor output because it is not possible to know where to
1714 send the decompressor output.
1716 When this option is set, the selected DEBUG_LL output method
1717 will be re-used for normal decompressor output on multiplatform

1733 kernel parameters to enable this console.

1742 bool "Write the current PID to the CONTEXTIDR register"
1743 depends on CPU_COPY_V6
1745 Enabling this option causes the kernel to write the current PID to
1746 the PROCID field of the CONTEXTIDR register, at the expense of some
1747 additional instructions during context switch. Say Y here only if you
1748 are planning to use hardware trace tools with this kernel.
1750 config DEBUG_SET_MODULE_RONX
1751 bool "Set loadable kernel module data as NX and text as RO"
1752 depends on MODULES && MMU
1754 This option helps catch unintended modifications to loadable
1755 kernel module's text and read-only data. It also prevents execution
1756 of module data. Such protection may interfere with run-time code
1757 patching and dynamic kernel tracing - and they might also protect
1758 against certain classes of kernel exploits.
1759 If in doubt, say "N".
