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 KGDB
	bool "Include kgdb kernel debugger"
	depends on DEBUGGER && (BROKEN || PPC_GEN550 || 4xx)
	select DEBUG_INFO
	help
	  Include in-kernel hooks for kgdb, the Linux kernel source level
	  debugger.  See <http://kgdb.sourceforge.net/> for more information.
	  Unless you are intending to debug the kernel, say N here.

	prompt "Serial Port"

config KGDB_TTYS0
	bool "ttyS0"

config KGDB_TTYS1
	bool "ttyS1"

config KGDB_TTYS3
	bool "ttyS3"

config KGDB_CONSOLE
	bool "Enable serial console thru kgdb port"
	depends on KGDB && 8xx || CPM2
	help
	  If you enable this, all serial console messages will be sent
	  over the gdb stub.
	  If unsure, say N.

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"
	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"
	depends on DEBUG_KERNEL && PPC32
	help
	  Include in-kernel support for the Abatron BDI2000 debugger.
	  Unless you are intending to debug the kernel with one of these
	  machines, say N here.

config BOOTX_TEXT
	bool "Support for early boot text console (BootX or OpenFirmware only)"
	depends PPC_OF && !PPC_ISERIES
	help
	  Say Y here to see progress messages from the boot firmware in text
	  mode. Requires either BootX or Open Firmware.

config SERIAL_TEXT_DEBUG
	bool "Support for early boot texts over serial port"
	depends on 4xx || LOPEC || MV64X60 || PPLUS || PRPMC800 || \
		PPC_GEN550 || PPC_MPC52xx

config PPC_OCP
	bool
	depends on IBM_OCP || XILINX_OCP
	default y
