This option will cause messages to be printed if free stack space
|
|
drops below a certain limit.

bool "Kprobes"

depends on DEBUG_KERNEL
|
|
help
|
|
Kprobes allows you to trap at almost any kernel address and
|
|
execute a callback function. register_kprobe() establishes
|
|
a probepoint and specifies the callback. Kprobes is useful
|
|
for kernel debugging, non-intrusive instrumentation and testing.
|
|
If in doubt, say "N".

config DEBUG_STACK_USAGE

bool "Stack utilization instrumentation"

|
|
help
|
|
Enables the display of the minimum amount of free stack which each
|
|
task has ever had available in the sysrq-T and sysrq-P debug output.
|
|
|
|
This option will slow down process creation somewhat.

help

Include in-kernel hooks for kernel debuggers. Unless you are

intending to debug the kernel, say N here.

Include in-kernel hooks for the xmon kernel monitor/debugger.

Unless you are intending to debug the kernel, say N here.

bool "Use separate kernel stacks when processing interrupts"
|
|
help
|
|
If you say Y here the kernel will use separate kernel stacks
|
|
for handling hard and soft interrupts. This can help avoid
|
|
overflowing the process kernel stacks.
