NAME

       kgdb_arch_handle_exception - Handle architecture specific GDB packets.

SYNOPSIS

       int kgdb_arch_handle_exception(int vector, int signo, int err_code, char * remcom_in_buffer, char * remcom_out_buffer,
				      struct pt_regs * regs);

ARGUMENTS

       vector
	   The error vector of the exception that happened.

       signo
	   The signal number of the exception that happened.

       err_code
	   The error code of the exception that happened.

       remcom_in_buffer
	   The buffer of the packet we have read.

       remcom_out_buffer
	   The buffer of BUFMAX bytes to write a packet into.

       regs
	   The struct pt_regs of the current process.

DESCRIPTION

       This function MUST handle the 'c' and 's' command packets, as well packets to set / remove a hardware breakpoint, if used. If there are
       additional packets which the hardware needs to handle, they are handled here. The code should return -1 if it wants to process more
       packets, and a 0 or 1 if it wants to exit from the kgdb callback.
