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

24 This determines which method will be used for unwinding kernel stack

26 livepatch, lockdep, and more.

38 bool "ARM EABI stack unwinder"
42 This option enables stack unwinding support in the kernel
43 using the information automatically generated by the
44 compiler. The resulting kernel image is slightly bigger but
45 the performance is not affected. Currently, this feature
46 only works with EABI compilers.

62 bool "Verbose user fault messages"
64 When a user program crashes due to an exception, the kernel can
65 print a brief message explaining what the problem was. This is
66 sometimes helpful for debugging but serves no purpose on a
67 production system. Most people should say N here.
69 In addition, you need to pass user_debug=N on the kernel command
70 line to enable this feature. N consists of the sum of:
72 1 - undefined instruction events
74 4 - invalid data aborts

85 executes before the console is initialized.
87 Note that selecting this option will limit the kernel to a single
88 UART definition, as specified below. Attempting to boot the kernel
89 image on a different platform *will not work*, so this option should
90 not be enabled for kernels that are intended to be portable.

1301 If you have a ZC702 board and want early boot messages to
1302 appear on the USB serial adaptor, select this option.
1305 bool "Kernel low-level debugging via EmbeddedICE DCC channel"
1307 Say Y here if you want the debug print routines to direct
1308 their output to the EmbeddedICE macrocell's DCC channel using
1309 co-processor 14. This is known to work on the ARM9 style ICE
1310 channel and on the XScale with the PEEDI.
1312 Note that the system will appear to hang during boot if there
1313 is nothing connected to read from the DCC.
1315 config DEBUG_SEMIHOSTING
1316 bool "Kernel low-level debug output via semihosting I/O"
1318 Semihosting enables code running on an ARM target to use
1319 the I/O facilities on a host debugger/emulator through a
1320 simple SVC call. The host debugger or emulator must have
1321 semihosting enabled for the special svc call to be trapped
1322 otherwise the kernel will crash.
1324 This is known to work with OpenOCD, as well as
1325 ARM's Fast Models, or any other controlling environment
1326 that implements semihosting.
1328 For more details about semihosting, please see
1329 chapter 8 of DUI0203I_rvct_developer_guide.pdf from ARM Ltd.
1331 config DEBUG_LL_UART_8250
1332 bool "Kernel low-level debugging via 8250 UART"
1334 Say Y here if you wish the debug print routes to direct
1335 their output to an 8250 UART. You can use this option
1336 to provide the parameters for the 8250 UART rather than
1337 selecting one of the platform specific options above if
1338 you know the parameters for the port.
1340 This option is preferred over the platform specific
1341 options; the platform specific options are deprecated
1342 and will be soon removed.

1345 bool "Kernel low-level debugging via efm32 UART"
1346 depends on ARCH_EFM32
1348 Say Y here if you want the debug print routines to direct
1349 their output to an UART or USART port on efm32 based
1350 machines. Use the following addresses for DEBUG_UART_PHYS:
1358 config DEBUG_LL_UART_PL01X
1359 bool "Kernel low-level debugging via ARM Ltd PL01x Primecell UART"
1361 Say Y here if you wish the debug print routes to direct
1362 their output to a PL01x Primecell UART. You can use
1363 this option to provide the parameters for the UART
1364 rather than selecting one of the platform specific
1365 options above if you know the parameters for the port.
1367 This option is preferred over the platform specific
1368 options; the platform specific options are deprecated

1788 This option influences the normal decompressor output for
1789 multiplatform kernels. Normally, multiplatform kernels disable
1790 decompressor output because it is not possible to know where to
1791 send the decompressor output.

1825 are planning to use hardware trace tools with this kernel.
