SLEEPING_THREAD_TO_G(9) 				     Kernel Debugger Internals					   SLEEPING_THREAD_TO_G(9)

NAME

       sleeping_thread_to_gdb_regs - Convert ptrace regs to GDB regs

SYNOPSIS

       void sleeping_thread_to_gdb_regs(unsigned long * gdb_regs, struct task_struct * p);

ARGUMENTS

       gdb_regs
	   A pointer to hold the registers in the order GDB wants.

       p
	   The struct task_struct of the desired process.

DESCRIPTION

       Convert the register values of the sleeping process in p to the format that GDB expects. This function is called when kgdb does not have
       access to the struct pt_regs and therefore it should fill the gdb registers gdb_regs with what has been saved in struct thread_struct
       thread field during switch_to.

       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 *);

	 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.
