So, gdb has knowledge of hardware breakpoints and knows how to use
them across the different processors? I would ask we consider using
a standard breakpoint interface to the kernel and allow the kernel
to implement the breakpoints as it desires. It seems having this
knowledge and synchronizing the necessary information across the
interface could be challenging.
