  unsigned long flags;
  int (* set_breakpoint) (unsigned long, char *);
  int (* remove_breakpoint) (unsigned long, char *);
  int (* set_hw_breakpoint) (unsigned long, int, enum kgdb_bptype);

MEMBERS

gdb_bpt_instr[BREAK_INSTR_SIZE]

: The instruction to trigger a breakpoint.

flags

: Flags for the breakpoint, currently just KGDB_HW_BREAKPOINT.

set_breakpoint

: Allow an architecture to specify how to set a software breakpoint.

remove_breakpoint

: Allow an architecture to specify how to remove a software breakpoint.

set_hw_breakpoint

: Allow an architecture to specify how to set a hardware breakpoint.

remove_hw_breakpoint

: Allow an architecture to specify how to remove a hardware breakpoint.

disable_hw_break

: Allow an architecture to specify how to disable hardware breakpoints for a single cpu.

remove_all_hw_break

: Allow an architecture to specify how to remove all hardware breakpoints.

correct_hw_break

: Allow an architecture to specify how to correct the hardware debug registers.

enable_nmi
