KGDB_ARCH(9)					     Kernel Debugger Internals					       STRUCT KGDB_ARCH(9)

NAME

       struct_kgdb_arch - Describe architecture specific values.

SYNOPSIS

       struct kgdb_arch {
	 unsigned char gdb_bpt_instr[BREAK_INSTR_SIZE];
	 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);
	 int (* remove_hw_breakpoint) (unsigned long, int, enum kgdb_bptype);
	 void (* disable_hw_break) (struct pt_regs *regs);
	 void (* remove_all_hw_break) (void);
	 void (* correct_hw_break) (void);
	 void (* enable_nmi) (bool on);
       };

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
	   Manage NMI-triggered entry to KGDB
