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.

NAME

       Devel::GDB::LowLevel - Low-level interface for communicating with GDB

DESCRIPTION

       This module is used internally by Devel::GDB.  It handles the low-level I/O of communicating with the GDB process.

CONSTRUCTOR

       new Spawns a GDB process.  Because this class only facilitates communication with GDB (not with the inferior process being debugged), you
	   have to decide what to do with the "STDIN", "STDOUT", and "STDERR" of that process.	There are a few options available:

	   *   If STDIN is a tty, we can have the inferior process communicate directly with the controlling tty (emulating the default behavior
	       of gdb):

		   $gdb = new Devel::GDB::LowLevel( '-execfile' => $path_to_gdb,
						    '-params'	=> $extra_gdb_params );

	   *   Or, we can create an "Expect" object to communicate with the inferior process:

		   $gdb = new Devel::GDB::LowLevel( '-create-expect' => 1 );
		   $expect = $gdb->get_expect_obj();

	   *   Or, we can create our own tty and use that:

		   $gdb = new Devel::GDB::LowLevel( '-use-tty' => '/dev/pts/123' );

METHODS

       send
	   Sends a raw line of text to GDB.  This should not contain any newlines (they will be stripped).  This method only sends a request, and
	   does not wait for a response.

       get_reader
	   Returns the file handle from which to read GDB responses.

       get_expect_obj
	   Returns the "Expect" object created in the constructor.  Dies if '-create-expect' was not passed to "new".

       interrupt
	   Send SIGINT to the GDB session, interrupting the inferior process (if any).
