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.

1303 bool "Kernel low-level debugging via ARM Ltd PL01x Primecell UART"
1305 Say Y here if you wish the debug print routes to direct
1306 their output to a PL01x Primecell UART. You can use
1307 this option to provide the parameters for the UART
1308 rather than selecting one of the platform specific
1309 options above if you know the parameters for the port.
1311 This option is preferred over the platform specific
1312 options; the platform specific options are deprecated
1313 and will be soon removed.

1684 bool "8250 UART is Palmchip BK-310x"
1685 depends on DEBUG_LL_UART_8250 || DEBUG_UART_8250
1687 Palmchip provides a UART implementation compatible with 16550
1688 except for having a different register layout. Say Y here if
1689 the debug UART is of this type.
1691 config DEBUG_UART_8250_FLOW_CONTROL
1692 bool "Enable flow control for 8250 UART"

1702 This option influences the normal decompressor output for
1703 multiplatform kernels. Normally, multiplatform kernels disable
1704 decompressor output because it is not possible to know where to
1705 send the decompressor output.
1707 When this option is set, the selected DEBUG_LL output method
1708 will be re-used for normal decompressor output on multiplatform
1712 config UNCOMPRESS_INCLUDE
1714 default "debug/uncompress.h" if ARCH_MULTIPLATFORM || ARCH_MSM || \
1715 PLAT_SAMSUNG || ARM_SINGLE_ARMV7M
1716 default "mach/uncompress.h"
1722 Say Y here if you want to have an early console using the
1723 kernel low-level debugging functions. Add earlyprintk to your
1724 kernel parameters to enable this console.

1732 config PID_IN_CONTEXTIDR
1733 bool "Write the current PID to the CONTEXTIDR register"
1734 depends on CPU_COPY_V6
1736 Enabling this option causes the kernel to write the current PID to
1737 the PROCID field of the CONTEXTIDR register, at the expense of some
1738 additional instructions during context switch. Say Y here only if you
1739 are planning to use hardware trace tools with this kernel.
1741 config DEBUG_SET_MODULE_RONX
1742 bool "Set loadable kernel module data as NX and text as RO"
1743 depends on MODULES && MMU
1745 This option helps catch unintended modifications to loadable
1746 kernel module's text and read-only data. It also prevents execution
1747 of module data. Such protection may interfere with run-time code
1748 patching and dynamic kernel tracing - and they might also protect
1749 against certain classes of kernel exploits.
1750 If in doubt, say "N".
