Hmm,  the key code of invoking kgdb_core was disabled by "#if 0".

The Hexagon kgdb implementation is incomplete; I work on it as time
permits and urgency requires.  I know from direct experience that,
for kernel bringup and stress testing on new platforms, that kdb is 
invaluable, being infinitely easier to use than any hardware debugger.
(cheaper, too)

This world could use a really cheap, easy-to-setup jtag debugger.
