Say Y here if you want to show the kernel pagetable layout in a
|
|
debugfs file. This information is only useful for kernel developers
|
|
who are working in architecture specific areas of the kernel.

It is probably not a good idea to enable this feature in a production
|
|
kernel.

help
|
|
Generate a warning if any W+X mappings are found at boot.
|
|
|
|
This is useful for discovering cases where the kernel is leaving
|
|
W+X mappings after applying NX, as such mappings are a security risk.
|
|
|
|
Look for a message in dmesg output like this:
|
|
|
|
arm/mm: Checked W+X mappings: passed, no W+X pages found.
|
|
|
|
or like this, if the check failed:
|
|
|
|
arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.
|
|
|
|
Note that even if the check fails, your kernel is possibly
|
|
still fine, as W+X mappings are not a security hole in
|
|
themselves, what they do is that they make the exploitation
|
|
of other unfixed kernel bugs easier.
|
|
|
|
There is no runtime or memory usage effect of this option
|
|
once the kernel has booted up - it's a one time check.
|
|
|
|
If in doubt, say "Y".

When the kernel produces a warning or oops, the kernel prints a

trace of the call chain. This option controls whether we include
|
|
the numeric addresses or only include the symbolic information.

help
|

When a user program crashes due to an exception, the kernel can
|
|
print a brief message explaining what the problem was. This is
|
|
sometimes helpful for debugging but serves no purpose on a
|
|
production system. Most people should say N here.
|
|
|
|
In addition, you need to pass user_debug=N on the kernel command
|
|
line to enable this feature. N consists of the sum of:
|
|
|
|
1 - undefined instruction events
|
|
2 - system calls
|
|
4 - invalid data aborts
|
|
8 - SIGSEGV faults
|
|
16 - SIGBUS faults

Some UART ports are connected to terminals that will use modem
|
|
control signals to indicate whether they are ready to receive text.
|
|
In practice this means that the terminal is asserting the special
|
|
control signal CTS (Clear To Send). If your debug UART supports
|
|
this and your debug terminal will require it, enable this option.
