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.

1295 bool "Kernel low-level debug output via semihosting I/O"
1297 Semihosting enables code running on an ARM target to use
1298 the I/O facilities on a host debugger/emulator through a
1299 simple SVC call. The host debugger or emulator must have
1300 semihosting enabled for the special svc call to be trapped
1301 otherwise the kernel will crash.
1303 This is known to work with OpenOCD, as well as
1304 ARM's Fast Models, or any other controlling environment
1305 that implements semihosting.
1307 For more details about semihosting, please see
1308 chapter 8 of DUI0203I_rvct_developer_guide.pdf from ARM Ltd.
1310 config DEBUG_LL_UART_8250
1311 bool "Kernel low-level debugging via 8250 UART"
1313 Say Y here if you wish the debug print routes to direct
1314 their output to an 8250 UART. You can use this option
1315 to provide the parameters for the 8250 UART rather than
1316 selecting one of the platform specific options above if
1317 you know the parameters for the port.
1319 This option is preferred over the platform specific
1320 options; the platform specific options are deprecated
1321 and will be soon removed.
1323 config DEBUG_LL_UART_EFM32

1327 Say Y here if you want the debug print routines to direct
1328 their output to an UART or USART port on efm32 based
1329 machines. Use the following addresses for DEBUG_UART_PHYS:

1338 bool "Kernel low-level debugging via ARM Ltd PL01x Primecell UART"
1340 Say Y here if you wish the debug print routes to direct

1342 this option to provide the parameters for the UART
1343 rather than selecting one of the platform specific
1344 options above if you know the parameters for the port.
1346 This option is preferred over the platform specific
1347 options; the platform specific options are deprecated
1348 and will be soon removed.

1743 This option influences the normal decompressor output for
1744 multiplatform kernels. Normally, multiplatform kernels disable
1745 decompressor output because it is not possible to know where to
1746 send the decompressor output.

1749 will be re-used for normal decompressor output on multiplatform

1780 are planning to use hardware trace tools with this kernel.
