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.
bool "Enable xmon by default"
depends on XMON
xmon is normally disabled unless booted with 'xmon=on'.
Use 'xmon=off' to disable xmon init during runtime.
