7 bool "Export kernel pagetable layout to userspace via debugfs"
8 depends on DEBUG_KERNEL
12 Say Y here if you want to show the kernel pagetable layout in a
13 debugfs file. This information is only useful for kernel developers
14 who are working in architecture specific areas of the kernel.
15 It is probably not a good idea to enable this feature in a production
19 # RMK wants arm kernels compiled with frame pointers or stack unwinding.
20 # If you know what you are doing and are willing to live without stack
21 # traces, you can get a slightly smaller kernel by setting this option to
22 # n, but then RMK will have to kill you ;).
25 depends on !THUMB2_KERNEL
26 default y if !ARM_UNWIND || FUNCTION_GRAPH_TRACER
28 If you say N here, the resulting kernel will be slightly smaller and
29 faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
30 when a problem occurs with the kernel, the information that is
31 reported is severely limited.
34 bool "Enable stack unwinding support (EXPERIMENTAL)"
38 This option enables stack unwinding support in the kernel
39 using the information automatically generated by the
40 compiler. The resulting kernel image is slightly bigger but
41 the performance is not affected. Currently, this feature
42 only works with EABI compilers. If unsure say Y.
46 depends on FUNCTION_TRACER && FRAME_POINTER
50 bool "Verbose user fault messages"
52 When a user program crashes due to an exception, the kernel can
53 print a brief message explaining what the problem was. This is
54 sometimes helpful for debugging but serves no purpose on a
55 production system. Most people should say N here.
57 In addition, you need to pass user_debug=N on the kernel command
58 line to enable this feature. N consists of the sum of:
60 1 - undefined instruction events
62 4 - invalid data aborts
66 # These options are only for real kernel hackers who want to get their hands dirty.
68 bool "Kernel low-level debugging functions (read help!)"
69 depends on DEBUG_KERNEL
71 Say Y here to include definitions of printascii, printch, printhex
72 in the kernel. This is helpful if you are debugging code that
73 executes before the console is initialized.
75 Note that selecting this option will limit the kernel to a single
76 UART definition, as specified below. Attempting to boot the kernel
77 image on a different platform *will not work*, so this option should
78 not be enabled for kernels that are intended to be portable.

1294 If you have a ZC702 board and want early boot messages to
1295 appear on the USB serial adaptor, select this option.
1298 bool "Kernel low-level debugging via EmbeddedICE DCC channel"
1300 Say Y here if you want the debug print routines to direct
1301 their output to the EmbeddedICE macrocell's DCC channel using
1302 co-processor 14. This is known to work on the ARM9 style ICE
1303 channel and on the XScale with the PEEDI.
1305 Note that the system will appear to hang during boot if there
1306 is nothing connected to read from the DCC.
1308 config DEBUG_SEMIHOSTING
1309 bool "Kernel low-level debug output via semihosting I/O"
1311 Semihosting enables code running on an ARM target to use
1312 the I/O facilities on a host debugger/emulator through a
1313 simple SVC call. The host debugger or emulator must have
1314 semihosting enabled for the special svc call to be trapped
1315 otherwise the kernel will crash.
1317 This is known to work with OpenOCD, as well as
1318 ARM's Fast Models, or any other controlling environment
1319 that implements semihosting.
1321 For more details about semihosting, please see
1322 chapter 8 of DUI0203I_rvct_developer_guide.pdf from ARM Ltd.
1324 config DEBUG_LL_UART_8250
1325 bool "Kernel low-level debugging via 8250 UART"
1327 Say Y here if you wish the debug print routes to direct
1328 their output to an 8250 UART. You can use this option
1329 to provide the parameters for the 8250 UART rather than
1330 selecting one of the platform specific options above if
1331 you know the parameters for the port.
1333 This option is preferred over the platform specific
1334 options; the platform specific options are deprecated
1335 and will be soon removed.

1338 bool "Kernel low-level debugging via efm32 UART"
1339 depends on ARCH_EFM32
1341 Say Y here if you want the debug print routines to direct
1342 their output to an UART or USART port on efm32 based
1343 machines. Use the following addresses for DEBUG_UART_PHYS:
1351 config DEBUG_LL_UART_PL01X
1352 bool "Kernel low-level debugging via ARM Ltd PL01x Primecell UART"
1354 Say Y here if you wish the debug print routes to direct
1355 their output to a PL01x Primecell UART. You can use
1356 this option to provide the parameters for the UART
1357 rather than selecting one of the platform specific
1358 options above if you know the parameters for the port.
1360 This option is preferred over the platform specific
1361 options; the platform specific options are deprecated

1785 This option influences the normal decompressor output for
1786 multiplatform kernels. Normally, multiplatform kernels disable
1787 decompressor output because it is not possible to know where to
1788 send the decompressor output.

1822 are planning to use hardware trace tools with this kernel.
