GDB hardware watchpoint information on i386


Is there information on how a GDB hardware watchpoint works on a i386.
More like internals of its working,
right from when the hardware watchpoint triggers a trap from processor
perspective(i386 processor supporting
hardware watchpoint).
Which function gets called in GDB to handle this? I am specifically
looking for information about "hooking" my
own?handler?to service?the watchpoint interrupt rather than needing to
invoke a GDB session and press 'c'.
