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.

1296 config DEBUG_SEMIHOSTING
1297 bool "Kernel low-level debug output via semihosting I/O"
1299 Semihosting enables code running on an ARM target to use
1300 the I/O facilities on a host debugger/emulator through a
1301 simple SVC call. The host debugger or emulator must have
1302 semihosting enabled for the special svc call to be trapped
1303 otherwise the kernel will crash.
1305 This is known to work with OpenOCD, as well as
1306 ARM's Fast Models, or any other controlling environment
1307 that implements semihosting.
1309 For more details about semihosting, please see
1310 chapter 8 of DUI0203I_rvct_developer_guide.pdf from ARM Ltd.

1315 Say Y here if you wish the debug print routes to direct
1316 their output to an 8250 UART. You can use this option
1317 to provide the parameters for the 8250 UART rather than
1318 selecting one of the platform specific options above if
1319 you know the parameters for the port.
1321 This option is preferred over the platform specific

1767 This option influences the normal decompressor output for
1768 multiplatform kernels. Normally, multiplatform kernels disable
1769 decompressor output because it is not possible to know where to
1770 send the decompressor output.

1804 are planning to use hardware trace tools with this kernel.
