menu "Kernel hacking"
source "lib/Kconfig.debug"
config DEBUG_STACKOVERFLOW
bool "Check for stack overflows"
depends on DEBUG_KERNEL
help
This option will cause messages to be printed if free stack space
drops below a certain limit.
config KPROBES
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"
depends on DEBUG_KERNEL
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.
config DEBUGGER
bool "Enable debugger hooks"
depends on DEBUG_KERNEL
help
Include in-kernel hooks for kernel debuggers. Unless you are
intending to debug the kernel, say N here.
config XMON
bool "Include xmon kernel debugger"
depends on DEBUGGER && !PPC_ISERIES
help
Include in-kernel hooks for the xmon kernel monitor/debugger.
Unless you are intending to debug the kernel, say N here.
Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise
nothing will appear on the screen (xmon writes directly to the
framebuffer memory).
The cmdline option 'xmon' or 'xmon=early' will drop into xmon very
early during boot. 'xmon=on' will just enable the xmon debugger hooks.
'xmon=off' will disable the debugger hooks if CONFIG_XMON_DEFAULT is set.
config XMON_DEFAULT
bool "Enable xmon by default"
depends on XMON
help
xmon is normally disabled unless booted with 'xmon=on'.
Use 'xmon=off' to disable xmon init during runtime.
config IRQSTACKS
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.
