6 config ARM_PTDUMP_DEBUGFS
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.
49 prompt "Choose kernel unwinder"
50 default UNWINDER_ARM if AEABI
51 default UNWINDER_FRAME_POINTER if !AEABI
53 This determines which method will be used for unwinding kernel stack
54 traces for panics, oopses, bugs, warnings, perf, /proc/<pid>/stack,
55 livepatch, lockdep, and more.
57 config UNWINDER_FRAME_POINTER
58 bool "Frame pointer unwinder"
59 depends on !THUMB2_KERNEL
60 select ARCH_WANT_FRAME_POINTERS
63 This option enables the frame pointer unwinder for unwinding
67 bool "ARM EABI stack unwinder"
71 This option enables stack unwinding support in the kernel
72 using the information automatically generated by the
73 compiler. The resulting kernel image is slightly bigger but
74 the performance is not affected. Currently, this feature
75 only works with EABI compilers.
82 config BACKTRACE_VERBOSE
83 bool "Verbose backtrace"
86 When the kernel produces a warning or oops, the kernel prints a
87 trace of the call chain. This option controls whether we include
88 the numeric addresses or only include the symbolic information.
90 In most cases, say N here, unless you are intending to debug the
91 kernel and have access to the kernel binary image.
97 bool "Verbose user fault messages"
99 When a user program crashes due to an exception, the kernel can
100 print a brief message explaining what the problem was. This is
101 sometimes helpful for debugging but serves no purpose on a
102 production system. Most people should say N here.
104 In addition, you need to pass user_debug=N on the kernel command
105 line to enable this feature. N consists of the sum of:
107 1 - undefined instruction events
109 4 - invalid data aborts
113 # These options are only for real kernel hackers who want to get their hands dirty.

116 depends on DEBUG_KERNEL
118 Say Y here to include definitions of printascii, printch, printhex
119 in the kernel. This is helpful if you are debugging code that
120 executes before the console is initialized.
122 Note that selecting this option will limit the kernel to a single
123 UART definition, as specified below. Attempting to boot the kernel
124 image on a different platform *will not work*, so this option should
125 not be enabled for kernels that are intended to be portable.

1337 This option enables a simple heuristic which tries to determine
1338 the motherboard's memory map variant (original or RS1) and then
1339 choose the relevant UART0 base address.
1341 Note that this will only work with standard A-class core tiles,

1403 Say Y here if you want the debug print routines to direct
1404 their output to the EmbeddedICE macrocell's DCC channel using
1405 co-processor 14. This is known to work on the ARM9 style ICE
1406 channel and on the XScale with the PEEDI.

1414 Semihosting enables code running on an ARM target to use
1415 the I/O facilities on a host debugger/emulator through a
1416 simple SVC call. The host debugger or emulator must have
1417 semihosting enabled for the special svc call to be trapped
1418 otherwise the kernel will crash.
1420 This is known to work with OpenOCD, as well as
1421 ARM's Fast Models, or any other controlling environment
1422 that implements semihosting.

1431 their output to an 8250 UART. You can use this option
1432 to provide the parameters for the 8250 UART rather than
1433 selecting one of the platform specific options above if
1434 you know the parameters for the port.

1532 control signals to indicate whether they are ready to receive text.
1533 In practice this means that the terminal is asserting the special

1535 this and your debug terminal will require it, enable this option.

1890 This option influences the normal decompressor output for
1891 multiplatform kernels. Normally, multiplatform kernels disable
1892 decompressor output because it is not possible to know where to
1893 send the decompressor output.

1896 will be re-used for normal decompressor output on multiplatform

1927 are planning to use hardware trace tools with this kernel.
