+ bool "Check for stack overflows"
+ depends on DEBUG_KERNEL
+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".
+ 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.
+ bool "Enable xmon by default"
+ depends on XMON
+config PPCDBG
+ bool "Include PPCDBG realtime debugging"
+ depends on DEBUG_KERNEL
+ 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.
