9 ---help---
10 Say Y here if you want to show the kernel pagetable layout in a
11 debugfs file. This information is only useful for kernel developers
12 who are working in architecture specific areas of the kernel.
13 It is probably not a good idea to enable this feature in a production
14 kernel.

20 ---help---
21 If this option is disabled, you allow userspace (root) access to all
22 of memory, including kernel and userspace memory. Accidental
23 access to this is obviously disastrous, but specific access can
24 be used by people debugging the kernel.
25
26 If this option is switched on, the /dev/mem file only allows
27 userspace access to memory mapped peripherals.
28
29 If in doubt, say Y.

50 This option enables stack unwinding support in the kernel
51 using the information automatically generated by the
52 compiler. The resulting kernel image is slightly bigger but
53 the performance is not affected. Currently, this feature
54 only works with EABI compilers. If unsure say Y.

62 bool "Verbose user fault messages"
63 help
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.
68
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:
71
72 1 - undefined instruction events
73 2 - system calls
74 4 - invalid data aborts
75 8 - SIGSEGV faults
76 16 - SIGBUS faults

1646 This enables support for the Trace Port Interface Unit driver, responsible
1647 for bridging the gap between the on-chip coresight components and a trace
1648 port collection engine, typically connected to an external host for use
1649 case capturing more traces than the on-board coresight memory can handle.

1663 This driver provides support for processor ETM3.x and PTM1.x modules,
1664 which allows tracing the instructions that a processor is executing
1665 This is primarily useful for instruction level tracing. Depending
1666 the ETM version data tracing may also be available.
