9 This option will cause messages to be printed if free stack space
10 drops below a certain limit.
12 config DEBUG_STACK_USAGE
13 bool "Stack utilization instrumentation"
14 depends on DEBUG_KERNEL && PPC64
15 help
16 Enables the display of the minimum amount of free stack which each
17 task has ever had available in the sysrq-T and sysrq-P debug output.
19 This option will slow down process creation somewhat.

25 Include in-kernel hooks for kernel debuggers. Unless you are

34 debugger. See <http://kgdb.sourceforge.net/> for more information.

60 If you enable this, all serial console messages will be sent
61 over the gdb stub.
62 If unsure, say N.

66 depends on DEBUGGER && !PPC_ISERIES
67 help
68 Include in-kernel hooks for the xmon kernel monitor/debugger.
69 Unless you are intending to debug the kernel, say N here.
70 Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise
71 nothing will appear on the screen (xmon writes directly to the
72 framebuffer memory).
73 The cmdline option 'xmon' or 'xmon=early' will drop into xmon
74 very early during boot. 'xmon=on' will just enable the xmon
75 debugger hooks. 'xmon=off' will disable the debugger hooks
76 if CONFIG_XMON_DEFAULT is set.
78 config XMON_DEFAULT
79 bool "Enable xmon by default"
80 depends on XMON
81 help
82 xmon is normally disabled unless booted with 'xmon=on'.
83 Use 'xmon=off' to disable xmon init during runtime.
85 config IRQSTACKS
86 bool "Use separate kernel stacks when processing interrupts"
87 depends on PPC64
88 help
89 If you say Y here the kernel will use separate kernel stacks
90 for handling hard and soft interrupts. This can help avoid
91 overflowing the process kernel stacks.

99 machines, say N here.

122 _will not boot_.
