- menu "Kernel hacking"

- 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.
- config XMON_DEFAULT
- bool "Enable xmon by default"
- depends on XMON
- config PPCDBG
- bool "Include PPCDBG realtime debugging"
- depends on DEBUG_KERNEL
- 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.
