42 42 Include in-kernel hooks for the xmon kernel monitor/debugger.
43 43 Unless you are intending to debug the kernel, say N here.
  44 + Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise
  45 + nothing will appear on the screen (xmon writes directly to the
  46 + framebuffer memory).
  47 + The cmdline option 'xmon' or 'xmon=early' will drop into xmon very
  48 + early during boot. 'xmon=on' will just enable the xmon debugger hooks.
  49 + 'xmon=off' will disable the debugger hooks if CONFIG_XMON_DEFAULT is set.

  55 + xmon is normally disabled unless booted with 'xmon=on'.
  56 + Use 'xmon=off' to disable xmon init during runtime.
