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 PPCDBG
bool "Include PPCDBG realtime debugging"
