config DEBUG_STACKOVERFLOW

	bool "Check for stack overflows"

	depends on DEBUG_KERNEL && PPC64

	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 && PPC64

	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 && PPC64

	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 DEBUG_KERNEL

	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"

	depends on PPC64

	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.



config BDI_SWITCH

	bool "Include BDI-2000 user context switcher"
