STRUCT 
KGDB_IO(9)					     Kernel Debugger Internals						 STRUCT KGDB_IO(9)

NAME

       struct_kgdb_io - Describe the interface for an I/O driver to talk with KGDB.

SYNOPSIS

       struct kgdb_io {
	 const char * name;
	 int (* read_char) (void);
	 void (* write_char) (u8);
	 void (* flush) (void);
	 int (* init) (void);
	 void (* pre_exception) (void);
	 void (* post_exception) (void);
	 int is_console;
       };

MEMBERS

       name
	   Name of the I/O driver.

       read_char
	   Pointer to a function that will return one char.

       write_char
	   Pointer to a function that will write one char.

       flush
	   Pointer to a function that will flush any pending writes.

       init
	   Pointer to a function that will initialize the device.

       pre_exception
	   Pointer to a function that will do any prep work for the I/O driver.

       post_exception
	   Pointer to a function that will do any cleanup work for the I/O driver.

       is_console
	   1 if the end device is a console 0 if the I/O device is not a console

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 (* remove_all_hw_break) (void);
	 void (* correct_hw_break) (void);
       };

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.

       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.
