STRUCT KGDB_ARCH(9) KGDB 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 (* 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.
