7 bool "Export kernel pagetable layout to userspace via debugfs"
8 depends on DEBUG_KERNEL
10 select ARM_PTDUMP_CORE
13 Say Y here if you want to show the kernel pagetable layout in a
14 debugfs file. This information is only useful for kernel developers
15 who are working in architecture specific areas of the kernel.
16 It is probably not a good idea to enable this feature in a production
21 bool "Warn on W+X mappings at boot"
23 select ARM_PTDUMP_CORE
25 Generate a warning if any W+X mappings are found at boot.
27 This is useful for discovering cases where the kernel is leaving
28 W+X mappings after applying NX, as such mappings are a security risk.
30 Look for a message in dmesg output like this:
32 arm/mm: Checked W+X mappings: passed, no W+X pages found.
34 or like this, if the check failed:
36 arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.
38 Note that even if the check fails, your kernel is possibly
39 still fine, as W+X mappings are not a security hole in
40 themselves, what they do is that they make the exploitation
41 of other unfixed kernel bugs easier.
43 There is no runtime or memory usage effect of this option
44 once the kernel has booted up - it's a one time check.
48 # RMK wants arm kernels compiled with frame pointers or stack unwinding.
49 # If you know what you are doing and are willing to live without stack
50 # traces, you can get a slightly smaller kernel by setting this option to
51 # n, but then RMK will have to kill you ;).
54 depends on !THUMB2_KERNEL
55 default y if !ARM_UNWIND || FUNCTION_GRAPH_TRACER
57 If you say N here, the resulting kernel will be slightly smaller and
58 faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
59 when a problem occurs with the kernel, the information that is
60 reported is severely limited.
63 bool "Enable stack unwinding support (EXPERIMENTAL)"
67 This option enables stack unwinding support in the kernel
68 using the information automatically generated by the
69 compiler. The resulting kernel image is slightly bigger but
70 the performance is not affected. Currently, this feature
71 only works with EABI compilers. If unsure say Y.
75 depends on FUNCTION_TRACER && FRAME_POINTER
79 bool "Verbose user fault messages"
81 When a user program crashes due to an exception, the kernel can
82 print a brief message explaining what the problem was. This is
83 sometimes helpful for debugging but serves no purpose on a
84 production system. Most people should say N here.
86 In addition, you need to pass user_debug=N on the kernel command
87 line to enable this feature. N consists of the sum of:
89 1 - undefined instruction events
91 4 - invalid data aborts
95 # These options are only for real kernel hackers who want to get their hands dirty.
97 bool "Kernel low-level debugging functions (read help!)"
98 depends on DEBUG_KERNEL
100 Say Y here to include definitions of printascii, printch, printhex
101 in the kernel. This is helpful if you are debugging code that
102 executes before the console is initialized.
104 Note that selecting this option will limit the kernel to a single
105 UART definition, as specified below. Attempting to boot the kernel
106 image on a different platform *will not work*, so this option should
107 not be enabled for kernels that are intended to be portable.

1293 select DEBUG_UART_PL01X
1295 This option selects UART0 at 0xb0090000. This is appropriate for
1296 Cortex-R series tiles and SMMs, such as Cortex-R5 and Cortex-R7
1298 config DEBUG_VF_UART
1300 depends on SOC_VF610
1302 Say Y here if you want kernel low-level debugging support
1303 on Vybrid based platforms.
1305 config DEBUG_VT8500_UART0
1306 bool "Use UART0 on VIA/Wondermedia SoCs"
1307 depends on ARCH_VT8500
1309 This option selects UART0 on VIA/Wondermedia System-on-a-chip
1310 devices, including VT8500, WM8505, WM8650 and WM8850.
1313 bool "Use ZTE ZX UART"
1314 select DEBUG_UART_PL01X

1336 their output to UART1 on the Zynq platform.
1338 If you have a ZC702 board and want early boot messages to
1339 appear on the USB serial adaptor, select this option.
1342 bool "Kernel low-level debugging via EmbeddedICE DCC channel"
1344 Say Y here if you want the debug print routines to direct
1345 their output to the EmbeddedICE macrocell's DCC channel using
1346 co-processor 14. This is known to work on the ARM9 style ICE
1347 channel and on the XScale with the PEEDI.
1349 Note that the system will appear to hang during boot if there
1350 is nothing connected to read from the DCC.
1352 config DEBUG_SEMIHOSTING
1353 bool "Kernel low-level debug output via semihosting I/O"
1355 Semihosting enables code running on an ARM target to use
1356 the I/O facilities on a host debugger/emulator through a
1357 simple SVC call. The host debugger or emulator must have
1358 semihosting enabled for the special svc call to be trapped
1359 otherwise the kernel will crash.
1361 This is known to work with OpenOCD, as well as
1362 ARM's Fast Models, or any other controlling environment
1363 that implements semihosting.
1365 For more details about semihosting, please see
1366 chapter 8 of DUI0203I_rvct_developer_guide.pdf from ARM Ltd.

1369 bool "Kernel low-level debugging via 8250 UART"
1371 Say Y here if you wish the debug print routes to direct
1372 their output to an 8250 UART. You can use this option
1373 to provide the parameters for the 8250 UART rather than
1374 selecting one of the platform specific options above if
1375 you know the parameters for the port.
1377 This option is preferred over the platform specific
1378 options; the platform specific options are deprecated
1379 and will be soon removed.

1387 machines. Use the following addresses for DEBUG_UART_PHYS:

1401 rather than selecting one of the platform specific
1402 options above if you know the parameters for the port.

1833 This option influences the normal decompressor output for
1834 multiplatform kernels. Normally, multiplatform kernels disable
1835 decompressor output because it is not possible to know where to
1836 send the decompressor output.

1839 will be re-used for normal decompressor output on multiplatform

1869 additional instructions during context switch. Say Y here only if you
1870 are planning to use hardware trace tools with this kernel.
