-@chapter Communication with GDB
-
-The RTEMS remote debugger will be accessed by GDB on a host machine
-through a communication link. We will use the TCP/IP stack included in RTEMS
-: the FreeBSD stack. The communication link will be based based on the UDP protocol
-and the BSD sockets which are parts of the FreeBSD stack. On top of these layers,
-we will plug a module which allows a simple communication between different
-machines (especially between different endianess machines) : the SUN Remote
-Procedure Call (SUN RPC). This code is freely available on the net and comes
-with a BSD like license. With this module, a process can invoke a procedure
-on a remote system. The RTEMS remote debugger will be seen by GDB as a SUN RPC
-server. Commands will be packed by the GDB SUN RPC client and sent to the server.
-This server will unpack these commands, execute them and, if needed, return
-results to the SUN RPC client.
-
-
-Only a minimal subset of the SUN RPC library must be implemented.
-For example, the portmapper related API which allows a dynamic allocation of
-port numbers will not be implemented and some specific UDP port numbers will
-be used to establish the communication between the host and the target. The
-SUN RPC library implements the XDR module (eXternal Data Representation) which
-is a standard way of encoding data in a portable fashion between different endian
-systems. Below are figures describing the additional code and data size for
-the minimal library implementation we currently have already implemented for
-RTEMS :
-
-@example
-$ size -x librpc.a 
-text  data bss dec hex filename 
-0x40e 0x0 0x0 1038 40e rpc_callmsg.o (ex librpc.a) 
-0x2f1 0x18 0x0 777 309 rpc_prot.o (ex librpc.a) 
-0x458 0x0 0x0 1112 458 svc.o (ex librpc.a) 
-0x4f 0x4 0x0 83 53 svc_auth.o (ex librpc.a) 
-0x75c 0x18 0x0 1908 774 svc_udp.o (ex librpc.a) 
-0x711 0x4 0x10 1829 725 xdr.o (ex librpc.a)
-0x149 0x0 0x0 329 149 xdr_array.o (ex librpc.a) 
-0x165 0x20 0x0 389 185 xdr_mem.o (ex librpc.a)
-@end example
-
-We have a constraint with the use of the UDP protocol. Because this
-protocol is connectionless, it is impossible, especially for the target, to
-detect if the connection is always active. On the other hand, using the TCP/IP
-protocols seems to be heavy especially if we plan to implement a dedicated micro
-stack for debug in the future. It can be a real problem to let the debugged
-process stopped during a long time even if there is no more debugger connected
-to the system. To avoid such a problem, the target must periodically test the
-connection with the host on another way than the one used to receive the commands.
-We must therefore open two communication ways so we need two fixed UDP port
-numbers. 
-
-@enumerate
-@item One port will be used by the debugger to send its commands to the
-debugged process and to receive the result of these commands. View from the
-remote debugger, this port will be called primary port. For this one, we choose
-arbitrarily the port number 2000. 
-@item The other socket will be used as secondary port by the target to sometimes
-test the connection between the host and the target. These tests will occur
-in specific situations, when a process will be stopped on a breakpoint, single
-step instruction or other means. This secondary port will also be used by the
-target to signal any change in the behavior of a debugged process (stopped,
-killed, waiting for,...). For the secondary port, we choose the port number
-2010.
-@end enumerate
-
-These two port numbers are used by the remote debugger to open the
-two communication sockets. GDB will use its own mean to choose its port numbers
-(probably the Unix portmapper). The figure layer shows the different
-layers we need to implement.

-@chapter Conclusion
-
-In this document we have presented how we envisage to add remote debugging facilities
-to RTEMS by implementing a remote debugger daemon for GDB. As any debug implemented
-in software, it will have limitation but we are confident that most of them
-can be removed by adding separate software components dedicated to debug activity.
-We must keep in mind that even with this approach, no software will enable the
-debug of code with interrupt entirely masked at processor level and that In
-Circuit Emulator (ICE) or use of BDM extension on the target board are the ultimate
-way to really debug any portion of an RTOS. BDM support in GDB is still weak
-but people are working on it and we may get something better in a near future.

-@chapter RTEMS Debugger Server Daemon
-
-We will describe in this section how this debugger server will be
-implemented on RTEMS environment. Our initial target is based on Intel Pentium
-and we will use an Ethernet link to communicate between the host and the target.
-
-The RTEMS remote debugger will be composed by several tasks and exception
-handlers :
-
-@itemize @bullet
-@item an initialization task which opens the sockets and runs the SUN RPC
-server. This task will also connect the interrupt handlers and launch the communication
-task
-@item a communication task which receives the SUN RPC commands, executes
-them and sends the result to the GDB client,
-@item A debuggee event management task which waits for events. We need a different
-task than the command management task in order to be able to still accept commands
-while no event has yet occurred for the debuggee. An example could be a continue
-command from GDB and then hitting to DEL key to see what is currently going
-on on the target side because an expected breakpoint is not caught...
-@item a debug exception handler which manages the hardware breakpoint and
-single step exceptions (INT 1 on Intel x86),
-@item a breakpoint exception handler which manages the software breakpoints
-exceptions (INT 3 on Intel x86),
-@item a default exception handler used to catch every possible errors make on the
-target system,
-@end itemize
-
-@c XXX figure reference
-@c XXX references to other sections
-Figure @b{remote debugger tasks and handlers} represents these
-different tasks and handlers. The synchronization between the different task
-and exception handlers will be described below in the section
-@b{Synchronization Among Tasks and Exception Handlers}.
-Some open issues we have faced for a prototype implementation are described
-in the section @b{Open Issues}. The temporary workaround we chose are described
-in chapter @b{Workarounds for Open Issues in Prototype}.
-
-
-@section The INITIALIZATION task
-
-This is the task that must be executed at the boot phase of RTEMS.
-It initializes the debug context. It must :
-
-@itemize @bullet
-@item open the UDP sockets,
-@item run the SUN RPC server main loop,
-@item create the COMMAND MANAGEMENT task,
-@item connect the DEBUG EXCEPTION handler,
-@item connect the SOFTWARE BREAKPOINT handler,
-@item delete itself.
-@end itemize
-If an error occurs at any step of the execution, the connections established
-before the error will be closed, before the initialization task deletes itself.
-
-
-@section The COMMAND_MNGT task
-
-This task is in charge of receiving the SUN RPC messages and executing
-the associated commands. This task must have an important priority because it
-must be executed each time a command message comes from the debugger. It must
-be executed even if one or both exception handlers are executed. But the COMMAND
-MANAGEMENT task must not block the TCP/IP module without which no message can
-be received.
-
-When not executing a command, this task is waiting for a SUN RPC message
-on the primary port. This idle state blocks the task, so the other active tasks
-can run. Once a message comes from Ethernet via the primary port, the COMMAND
-MANAGEMENT task wakes up and receives the message which is a request from GDB.
-This request is sent to the SUN RPC server code which extracts the command and
-its arguments, executes it and, if needed, sends a result to GDB. After having
-performed these actions, the task sleeps, waiting for another message. 
-
-A particular case is the reception of the ATTACH command : in this
-case the COMMAND_MNGT task creates the EVENT_MNGT task described below before
-going to wait on UDP socket again.
-
-
-@section The EVENT_MNGT task
-
-This task is in charge of managing events happening on the debuggee such as
-breakpoint, exceptions. This task does a basic simple loop waiting for event
-on a synchronization variable. It is waken up by exception handlers code. It
-then signals GDB that an event occurred and then go sleeping again as further
-requests will be processed by the COMMAND_MNGT task.
-
-
-@section The DEBUG EXCEPTION handler
-
-This handler is connected to the DEBUG exception (INT 1 on Intel ix86).
-This exception is entered when :
-
-@itemize @bullet
-@item executing a single-step instruction,
-@item hardware breakpoint condition is true,
-@end itemize
-These events will be treated by the debugger because they are the
-primary event used when debugging a software for instruction stepping. In both
-cases, the DEBUG EXCEPTION handler code is executed. Please note that the execution
-context of the exception handler is the supervisor stack of the task that generated
-the exception. This implies:
-
-@itemize @bullet
-@item We may sleep in this context,
-@item We have as many possible execution context for the DEBUG EXCEPTION handler as
-we need to,
-@item When we enter the high level exception handler code, a normalized exception
-context has been pushed on the system stack and a pointer to this context is
-available as the first argument (cf cpukit/score/cpu/i386/cpu.c for more
-details),
-@end itemize
-First the exception handler wakeup the EVENT_MNGT task. Then it will
-cause the faulting thread to sleep on a synchronization object. As soon as GDB
-receives the event notifying that the debuggee status has changed, it will start
-sending requests to get the debuggee status (registers set, faulty task id,
-...). These requests are handled by the COMMAND MANAGEMENT task. When this task
-receive a PTRACE_CONT command it will resume the execution of the task that
-caused the exception by doing a V on the synchronization object. 
-
-
-@section The BREAKPOINT EXCEPTION handler
-
-This handler is connected to the BREAKPOINT exception (INT3 on Intel
-Ix86). Each time the debugger wants to place a software breakpoint in the debuggee,
-a debuggee opcode is temporarily replaced by an instruction causing BREAKPOINT
-exception (the ``INT 3'' instruction on Intel ix86). When ``INT 3'' is executed,
-the BREAKPOINT handler is executed. Otherwise, the exception processing is the
-same than the one described in previous section.
-
-
-@section Synchronization Among Tasks and Exception Handlers
-
-The previous chapters have presented a simplified and static view of the various
-tasks and exceptions handlers. This chapter is more focussed on synchronization
-requirements about the various pieces of code executed when RGDBSD is operating.
-
-
-@subsection Implicit Synchronization Using Task Priorities
-
-This chapter is relevant on Uniprocessor System (UP) only. However, it will
-also list the requirements for explicit synchronization on Multi-processor Systems
-(MP). Below are the task priorities sorted by high priority. They are not supposed
-to be equal :
-
-@enumerate
-@item Network Input Task. This is the highest priority task. This can be regarded
-as a software interrupt task for FreeBSD code,
-@item RGDBSD command task. As this task waits on UDP sockets, it shall not prevent
-the previous task from running. As the main debug entry point, it should preempt
-any other task in the system,
-@item RGDBSD event task. This task should preempt any task but the two mentionned
-before to signal a debug event to GDB. The command task shall be able to preempt
-this task for emergency command such as DEL, or REBOOT,
-@item Applications tasks (task we are able to debug),
-@end enumerate
-
-Using theses priorities eliminates the need for adding more synchronization
-objects in the next section. My belief is that symmetric MP support will require
-more important change in the RTEMS than RGDBSD itself like multiple scheduler
-queues, task to processor binding for non symmetric IO, use a different implementation
-for @emph{task_disable_preemption}, ...
-
-
-@subsection Explicit Synchronization
-
-This chapter will describe the synchronization variables that need to be implemented
-in order to sequence debug events in a way that is compatible with what GDB
-code expects. The root of the problem is that GDB code mainly expects that once
-a debug event has occurred on the debuggee, the entire debuggee is frozen and
-no other event will occur before the CONTINUE command is issued. This behavior
-is hard to achieve in our case as once we hit a breakpoint, only the task that
-hits the breakpoint will be asleep on a synchronization object. Other tasks
-may hit other breakpoints while we are waiting commands from GDB generating
-potential unexpected events. There is a solutions if RGDBSD itself use RTEMS
-threads to fix this problem by creating a task that loops forever at a priority
-superior to any debugged task but below RGDBSD task priorities. Unfortunately
-this will not work for the case we use the nano-kernel implementation and we
-think it is better to study synchronization problems now. We also expects that
-multi-thread debug support hardening in GDB will remove some event serializations
-requirements. Here is the list of synchronization variables we plan to use and
-their usage. They are all regular semaphores. They are not binary semaphores
-because the task that does V is not the task that has done the P.
-
-@itemize @bullet
-@item @emph{WakeUpEventTask} : used by exception handler code to wake up the EVENT_MNGT
-task by doing a V operation on this object. When target code is running normally
-the EVENT_MNGT task sleeps due to a P operation on this semaphore,
-@item @emph{SerializeDebugEvent} : used to serialize events in a way compatible to
-what GDB expects. Before doing a V operation on @emph{WakeUpEventTask}, the
-exception handler does a P on this semaphore to be sure processing of another
-exception is not in progress. Upon reception of a CONTINUE command, the COMMAND_MNGT
-task will issue a V operation so that the exception code can wake up EVENT_MNGT
-task using the mechanism described above,
-@item @emph{RestartFromException} : (in fact one semaphore per task) used by exception
-handling code to put a faulty task to sleep once it has generated an exception
-by doing a P operation on this semaphore. In the case the exception was generated
-due to a breakpoint, GDB command will modify back the BREAKPOINT opcode to the
-original value before doing the CONTINUE command. This command will perform
-a V on this semaphore. In the case it is a real non restartable exception (faulty
-memory reference via invalid pointer for example), GDB will not allow to restart
-the program avoiding any loop. So not special analysis of cause of exception
-is foreseen as far as RGDBSD code is concerned,
-@end itemize
-
-@section Open Issues
-
-Here are some problems we have faced while implementing our prototype :
-
-@table @b
-@item [Protected ReadMem/WriteMem (I1)]:
-A GDB user can request to see the content
-of a corrupted pointer. The request PEEK_DATA will be performed by the COMMAND_MNGT
-task. It shall not enter the default exception handler set by RGDBSD or it will
-cause a dead lock in the RGDBSD code. Replacing the default exception vector
-before calling @b{readMem/writeMem} can be temporarily sufficient but :
-
-@itemize @bullet
-@item It will never work on MP system as it will rely on task priorities to insure
-that other task will not cause exceptions while we have removed the default
-exception handler,
-
-@item This feature should not be usable in RGDBSD only but also by an embedded debugger
-that may run without any task. It is also unavoidable in case of protected memory
-and in this case no priority mechanism can be used,
-
-@item In the case of using RGDBSD code on a dedicated nano kernel, this code will
-be called from interrupt level and we need a way to be sure we can debug other
-interrupts that may also cause exceptions,
-@end itemize
-
-@item [ATTACH Command Implementation (I2)]:
-After the @emph{target rtems symbolic_ip_target_name}
-command, the normal operation is to issue an @emph{attach lid} command where
-@emph{lid} represents a valid execution context. For Unix this is a process
-id, for other multi-tasking system this is the id of a thread. After the attach
-command, GDB expects to be waken up in the same manner as it is for normal events.
-Once waken up it expects to have a complete register context available and also
-that the target task is in a stopped state and that it can restart it using
-the regular CONTINUE command. In RTEMS there is a way to get force a thread
-to become inactive via @emph{rtems_task_suspend} but no way to get the full
-registers set for the thread. A partial context can be retrieved from the task
-@emph{Registers} data structure. On the other hand, relying on @emph{rtems_task_suspend}
-will be a problem for the nano-kernel implementation.
-
-@item [Stopping Target System (I3)]:
-Allthough it might not be obvious, most of the
-actions made by a GDB user assume the target is not running. If you modify a
-variable via the @emph{set variable = value} command you expect that the value
-is the one you have put when restarting. If a still running task modifies the
-same value in the mean time, this may be false. On the other hand, stopping
-all the tasks on the target system impose to have a very deep knowledge of the
-system. Using an interrupt driven RGDBSD, may facilitate the implementation
-on the nano-kernel. 
-
-@item [Getting Tasks Contexts (I4)]:
-As previously mentionned there is no way to get
-tasks execution contexts via the RTEMS API. This is needed when debugging for
-example via this classical sequence :
-
-@enumerate
-
-@item @emph{(gdb) target rtems symbolic_ip_target_name}
-
-@item @emph{(gdb) info threads <=} get a thread list on screen
-
-@item @emph{(gdb)} @emph{attach thread_id} <= thread_id is one of the thread in
-the list
-
-@item @emph{(gdb) b a_function_of_interest }
-
-@item @emph{(gdb) continue}
-
-@item @emph{(gdb)} @emph{backtrace} <= print the call stack on the screen once we
-have hit the breakpoint
-
-@item @emph{(gdb) thread target another_thread_li <=} change implicit current thread
-value for gdb commands
-
-@item @emph{(gdb)} @emph{backtrace <=} should print the backtrace for the chosen thread
-@end enumerate
-In our execution model, we have a valid context only for the threads that hits
-the breakpoint as it has been pushed by the exception handler code. The other
-thread is still running and during the various RPC requesting memory access,
-it even changes as the COMMAND_MNGT thread is going to sleep. So the backtrace
-command will fail. We must find a way to make this work as it is very usefull
-when debugging multi-threaded programs,
-
-
-@item [Backtrace Stop convention (I5)]:
-The backtrace command on RTEMS task does not
-gracefully terminate as GDB does not find some backtrace termination condition
-it expects.
-@end table
-
-@section Workarounds for Open Issues in Prototype
-
-@table @b
-
-@item [(I1)]:
-Not implemented.We would rather like to work on the formalization of
-per thread flags and global flags that are much more general than any kludge
-we could implement,
-
-@item [(I2)]:
-We have tried two solutions in our prototype. The first one was to use
-the @emph{idle} thread context contained in the @emph{Registers} task control
-block field. The drawback of this solution was that we had to implement specific
-code for the continue operation immediately following the attach command. We
-then decided to create a dedicated task that will only exist during the attach
-phase. This task will call the ``ENTER_RGDB'' exception. This call will execute
-the Exception Handler that saves a valid context and that notifies a change
-to GDB. After the first CONTINUE command from GDB, this task will continue its
-execution and delete itself,
-
-@item [(I3)]:
-As explained above in the synchronization chapter, we choose to serialize
-events in a way that makes GDB think the system is frozen,
-
-@item [(I4)]:
-As a temporary fix, we have called @emph{rtems_task_suspend} and used
-the context switch contex for tasks that are unknown to RGDBSD,
-
-@item [(I5)]:
-Not Implemented yet. If I remember correctly, setting the frame pointer
-to 0 at task initialization for CISC processor solves this problem (ebp = 0x0
-on Intel or a6 = 0x0 on 680x0). This should be done in rtems_task_create function
-in the path to really starts the task for the first time. The processor/system
-specific stop condition can be found as macros in the GDB source tree.

-@chapter A Rapid Tour of GDB Internals
-
-To help the reader to understand what needs to be implemented, we
-will present briefly how GDB works regardless if the target is local or remote.
-A debugger is a tool which enables control of the execution of software on a
-target system. In most of cases, the debugger connects to a target system, attaches
-a process, inserts breakpoints and resumes execution. Then the normal execution
-is completely events driven (process execution stopped due to a breakpoint,
-process fault, single-step,...) coming from the debuggee. It can also directly
-access some parts of the target processor context (registers, data memory, code
-memory,...) and change their content. Native GDB debugger can just be seen as
-special cases where the host and the target are on the same machine and GDB
-can directly access the target system debug API.
-
-
-In our case, the host and the target are not on the same machine and
-an Ethernet link is used to communicate between the different machines. Because
-GDB needs to be able to support various targets (including Unix core file, ...),
-each action that needs to be performed on the debuggee is materialized by a
-field of the following @emph{targets_op}s structure : 
-
-@example
-struct target_ops
-@{
-  char         *to_shortname;   /* Name this target type */
-  char         *to_longname;    /* Name for printing */
-  char         *to_doc;    /* Documentation.  Does not include trailing
-                              newline, and starts with a one-line
-                              description (probably similar to
-                              to_longname). */
-  void        (*to_open) PARAMS ((char *, int));

-  int         (*to_wait) PARAMS ((int, struct target_waitstatus *));
-  void        (*to_fetch_registers) PARAMS ((int));
-  void        (*to_store_registers) PARAMS ((int));
-  void        (*to_prepare_to_store) PARAMS ((void));
-
-  /* Transfer LEN bytes of memory between GDB address MYADDR and
-     target address MEMADDR.  If WRITE, transfer them to the target,
-     else transfer them from the target.  TARGET is the target from
-     which we get this function.
-
-     Return value, N, is one of the following:
-
-     0 means that we can't handle this.  If errno has been set,
-     it is the error which prevented us from doing it (FIXME:
-     What about bfd_error?).
-
-     positive (call it N) means that we have transferred N bytes
-     starting at MEMADDR.  We might be able to handle more bytes
-     beyond this length, but no promises.
- 
-     negative (call its absolute value N) means that we cannot
-     transfer right at MEMADDR, but we could transfer at least
-     something at MEMADDR + N.  */
-
-  int         (*to_xfer_memory)
-                 PARAMS ((CORE_ADDR memaddr, char *myaddr,

-@};
-@end example
-
-This structure contains pointers to functions (in C++, this would
-be called a virtual class). Each different target supported by GDB has its own
-structure with the relevant implementation of the functions (some functions
-may be not implemented). When a user connects GDB to a target via the ``target''
-command, GDB points to the structure corresponding to this target. Then the
-user can attache GDB to a specific task via the ``attach'' command. We have
-therefore identified two steps to begin a remote debug session :
-
-@enumerate
-@item the choice of the target type (in our case RTEMS),
-@item the choice of what to debug (entire system, specific task,...),
-@end enumerate
-Note that in the case of natives debugger, the choice of the target is implicitly
-performed by commands like @b{run}, @b{attach}, @b{detach}. Several
-figures will now be described showing the main steps of a debug session. 
-
-@c XXX figure reference
-Figure @b{Debug session initialization} explains how the debugger connects to the target
-:
-
-@enumerate
-@item  The debugger opens a connection to the target. The word ``connection''
-doesn't only mean Ethernet or serial link connection but all the ways by which
-a process can communicate with another one (direct function call, messages mailbox,
-...),
-@item  The targets checks if it can accept or reject this connection,
-@item  If the connection is accepted, the host ``attaches'' the process,
-@item  the target stops the process, notifies a child's stop to the host
-and waits for command,
-@item  the host can ask information about the debugged process (name, registers,...)
-or perform some action like setting breakpoints, ...
-@end enumerate
-
-@c XXX figure reference
-Figure @b{Breakpoint and process execution} explains how the debugger manages the
-breakpoints and controls the execution of a process :
-
-@enumerate
-@item  The host asks the debuggee what is the opcode at the concerned address
-in order for GDB to memorize this instruction,
-@item  the host sends a CONTINUE command : it asks the target to write the
-``DEBUG'' opcode (for example, the INTEL ``DEBUG'' opcode is INT3 which
-generate a breakpoint trap) instead of the debugged opcode.
-@item  then the host waits for events,
-@item  after the change of instruction, the target resumes the execution
-of the debuggee,
-@item  when the ``DEBUG'' opcode is executed, the breakpoint exception
-handler is executed and it notifies the host that the process is stopped. Then
-it waits for commands (if no command is sent after a certain amount of time,
-the connection will be closed by the target).
-@item  the host asks the target to re-write the right opcode instead of the
-''DEBUG'' opcode and then can ask information
-@end enumerate
-
-@c XXX figure reference
-Figure @b{Breakpoint and process execution} also shows the case of other ``CONTINUE''
-commands (remember that the ``DEBUG'' opcode has been replaced by the right
-instruction): 
-
-@enumerate
-@item  Host sends first a ``single step'' command to execute the debugged
-instruction,
-@item  It then waits for ``single step`` exception event,
-@item  the target, once the single step executed, calls the debug exception
-handler. It notifies the host that execution is suspended and wait for commands.
-@item  the host asks the target to re-write the ``DEBUG'' opcode (breakpoint
-trap) instead of the debugged one.
-@item  then the host sends a ``CONTINUE'' command in order the target to
-resume the process execution to the next breakpoint.
-@end enumerate
-
-@c XXX figure reference
-Figure @b{Detach a process and close a connection} explains how the debugger disconnects from
-a target :
-
-@enumerate
-@item  the host sends a detach command to the target.
-@item  the target detaches the concerned process, notifies the detachment
-and resumes the process execution.
-@item  once notified, the host sends a close connection command.
-@item  the target closes the connection.
-@end enumerate
-These 3 examples show that the mains actions that are performed by
-the host debugger on the target are only simple actions which look like :
-
-@itemize @bullet
-@item read/write code,
-@item read/write data,
-@item read/write registers,
-@item manage exceptions,
-@item send/receive messages to/from the host.

-@chapter Interfacing GDB with RTEMS as a Target
-
-@c XXX figure reference
-So, basically, porting GDB to RTEMS environment requires implementing
-the functions contained in the target_ops structure. The native debugger implementation
-(where the host machine is also the target one) uses direct function calls.
-For our needs (remote debugging), these functions must be implemented to support
-the encapsulation in UDP/IP layers and communications between different types
-of host machines : the best solution is use the SUN Remote Procedure Calls API
-(SUN RPC). This SUN RPC module will be explained below (see paragraph @b{Communication with GDB}).
-
-We can note that the functions described in the target_ops structure
-are high-level functions. The main reason is that GDB was designed in order
-to be able to use monitor firmware as a debug server. In the case of a Unix
-OS target, these high-level functions are implemented themselves using a lower
-level POSIX API. Because we want to simplify the code running on the target
-and decrease its size of this code, we propose to use the POSIX layer API used
-for the debug like @b{waitpid}, @b{ptrace}, ... Due to the GDB working
-mode and due to our requirements, we can establish here a non-exhaustive list
-of some commands required to implement the previously described functions :
-
-@itemize @bullet
-@item set up a connection with a target,
-@item close a connection,
-@item send a signal to the specified process,
-@item get a list of process/thread/connection running,
-@item control process under debug,
-@item ...
-@end itemize
-Control means that, with this function, we can read, write the memory
-of the debuggee, insert breakpoint to stop the process and resume the process
-execution. This command can be implemented by emulating in the RTEMS environment
-a Unix function called ``ptrace''. This function allows the control of a child
-process. The ``ptrace'' function has some sub-functions which are described
-below (some of these actions and standardized, the others are added due to our
-needs) :
-
-@itemize @bullet
-@item PTRACE_PEEKTEXT, PTRACE_PEEKDATA : read word at address,
-@item PTRACE_POKETEXT, PTRACE_POKEDATA :write word at address,
-@item PTRACE_CONT : restart after signal,
-@item PTRACE_KILL : send the child a SIGKILL to make it exit,
-@item PTRACE_SINGLESTEP : set the trap flag for single stepping,
-@item PTRACE_ATTACH : attach to the process specified,
-@item PTRACE_DETACH : detach a process that was previously attached.
-@end itemize
-This list only contains the command that are described in the ptrace
-Unix manpage. For some specific needs (debug of one task among several ones,
-register read/write,...), it is possible to create some special ptrace commands
-as described after :
-
-@itemize @bullet
-@item get current task registers,
-@item set current task registers,
-@item list of the threads,
-@item identifier of the target thread,
-@item restart to address,
-@item set breakpoint at address,
-@item clear breakpoint,
-@item get breakpoints,
-@item load dynamically a task,
-@item ...
-@end itemize
-This list is not exhaustive and can be increased due to the needs.
-All the described functions will not be implemented in a first version, only
-the strictly needed. If some commands are added, the modifications must be implemented
-both in RTEMS and in GDB.

-@chapter Introduction
-
-The TOOLS project aims to provide a complete development environment
-for RTEMS OS. This environment must be as close as possible to the Chorus one
-(gnu compiler, gnu linker, gnu debugger, ...), because it is currently the OS
-which is the most used at CRF and we want to simplify the migration path from
-the ChorusOs environment to the RTEMS environment. One important item of this
-development environment is the remote debugger which allows the developer to
-debug his software on a target machine from a host machine via a communication
-link (Ethernet, serial link, ...).
-
-
-The choice of GDB as debugger has been made with because in CRF, every
-developer, which uses the ChorusOs development environment, debugs his software
-using the remote debugging functionality of GDB. Providing a remote GDB debug
-server running on RTEMS, will enable the developers to use transparently the
-same debugger for a different RTOS. Another reason for the choice of GDB is
-its constant evolution, and that it can be interfaced with graphic user interfaces
-like DDD providing a very powerfull debugging environment.
-
-
-The subject of this document is to explain how GDB works and the way
-to implement a daemon on RTEMS that will be used as a debugger server for a
-GDB client. We will call this daemon Rtems GDB Debug Server Daemon (RGDBSD).
-We aim to provide this debugger running at least on 2 host systems : Linux 2.x
-and Solaris 2.5.1 as they are the two platforms used for developing Chorus applications
-today.

-@chapter Objectives
-
-@c XXX reference
-This section is intended to clearly define the current objectives of our work.
-First, we will try here to list some ambitious requirements for the debugger
-in section @b{List of Requirements}. These requirements will deliberately be much more
-ambitious than what we will provide directly ourselves in the hope that the
-Internet development model will enable others to implement some features we
-rejected for man-power reasons in the first step. We are committed to do the
-core work and redistribute it but would appreciate any comment and enhancement.
-Then, in section @b{Requirements Analysis} we will analyze each requirement to see
-what technical problem must be solved if we want to fullfill it. After this
-analysis, we will determine in section @b{Requirements Selection} the requirements we
-chose to implement and the ones we will not. We will then clearly identify the
-limits of our solution in section @b{Implied Restrictions}.
-
-
-@section List of Requirements
-
-We will identify here possible requirements for the type of debug that may be
-provided :
-
-@table @b
-
-@item [(R1)]:
-We want to use GDB as the front-end debugger,
-
-@item [(R2)]:
-We want to support at least Intel and PowerPC as target processor architecture,
-
-@item [(R3)]:
-We want to use the GDB thread debugging interface,
-
-@item [(R4)]:
-We want to be able to debug a remote target over a serial line,
-
-@item [(R5)]:
-We want to be able to debug a remote target over Ethernet,
-
-@item [(R6)]:
-The set of target code path we will be able to debug using RGDBSD must
-be clearly identified. It will be called Debug Path Set (@emph{DPS}) in the
-remaining of this document,
-
-@item [(R7)]:
-@emph{DPS} must include the RTEMS core executive itself,
-
-@item [(R8)]:
-@emph{DPS} must include the FreeBSD stack, 
-
-@item [(R9)]:
-@emph{DPS} must include anything but the FreeBSD stack and the RTEMS
-core executive,
-
-@item [(R10)]:
-We want to enable several persons to debug different parts of the code
-running on the target,
-
-@item [(R11)]:
-As much as possible the system must be frozen during a debug session
-so that debugging a particular portion of code does not prevent another part
-from functioning,
-@end table
-
-@section Requirements Analysis
-
-@table @b
-
-@item [(R1)]:
-Worth recalling it. It mainly imposes few restrictions on the binary
-files type, target processor type as :
-
-@itemize @bullet
-
-@item the binary format must be understood by GDB (to find debugging information).
-Elf, Coff and A.out are the main formats currently supported. Elf/Dwarf 2.0
-binary support will be our main target as they are the preferred format for
-Intel and PowerPC processors. No change in GDB will be required for other binaries
-except may be a new configuration file changing the binary/debug file format,
-
-@item the processor must be supported for disassemble/step instruction command,
-
-@item the target system must be supported. As far as I know RTEMS is not currently
-@emph{officially} supported anyway,
-@end itemize
-
-@item [(R2)]:
-Our primary targets are Intel and PowerPC. We however do not think implementing
-RGDBSD for other processors will be a heavy task. It will mainly require :
-
-@enumerate
-@item Implementing exception handling for the target processor, 
-
-@item Interfacing the generic part of RGDBSD with the low level exception handling
-and make RGDBSD aware of exception used for debugging (usually illegal instruction
-or dedicated trap, single step),
-
-@item Making GDB aware of the frame layout pushed on exceptions,
-
-@item Implement the code for data transfer for the exception frame,
-
-@item Implement code to copy data cache back to main memory and invalidate instruction
-cache. This is needed in order to be sure opcode modification used to set breakpoint
-that use the data cache will be proagated to the instruction cache,
-@end enumerate
-
-As soon as we will have completed the first core work a document describing
-how to port it to a new processor should be written. So far we will organize
-the source tree with processor dependent directories so that port will be as
-easy as possible. May be a bare processor support should be created,
-
-
-@item [(R3)]:
-GDB already has an interface for manipulating multi-threaded programs.
-This interface is rather weak at the moment but it will certainly be improved
-in the future with the generalization of POSIX thread API on Linux and other
-operating systems. This implies that either GDB or RGDBSD is able to obtain
-the list of threads currently executing. The choice of implementing this in
-GDB or RGDBSD is a tradeof between target code size and simplicity,
-
-@item [(R4)]:
-Regular GDB code contains clients code for debugging over a serial line.
-However only few functions are implemented. We would like to provide a better
-support and to uniformize serial line debugging with debugging over Ethernet
-via the use of SLIP,
-
-@item [(R5)]:
-Regular GDB code contains client code for debugging over Ethernet for
-VxWorks via the SUN RPC library. So there will be at least one starting point
-to implement remote debugging over Ethernet via SUN RPC. The Chorus remote debugging
-code has been disclosed under GPL and also contains code for debugging suing
-SUN RPC,
-
-@item [(R6)]:
-Due to a classical chicken and egg problems, the remote debugging daemon
-cannot be used to debug code it uses to function. Thus depending on the API
-used by RGDBSD, some parts of the target system will not be debuggable via GDB.
-The most important point is documentation because my feeling is that implementing
-RGDBSD on a totally different @emph{dedicated} nano kernel should be possible,
-
-@item [(R7)]:
-RTEMS core executive is a real-time OS which implements priority level
-scheduling, synchronization objects, and interrupt handling. As mentioned in
-previous item, we may not debug theses features if RGDBSD uses them. This requirement
-is thus very strong because it impose that :
-
-@enumerate
-
-@item RGDBSD is totally interrupt driven (no thread API available),
-
-@item But it does not use RTEMS interrupt management,
-
-@item Nor does not use RTEMS exception management,
-
-@item RGDBSD must provide its own UDP/IP stack as the current FreeBSD code rely on
-tasks switching and RTEMS provided synchronization object for input path handling,
-@end enumerate
-
-So our feeling is that the @b{(R7)} more or less requires to write a @emph{dedicated}
-nano kernel with a very small dedicated UDP/IP stack.
-
-
-@item [(R8)]:
-GDB remote debugging over Ethernet code communicates with the remote
-target via the SUN RPC protocol. This requires a UDP/IP protocol and a minimal
-socket like interface. In RTEMS environment, this feature is currently provided
-by the FreeBSD stack. Again, if we use the FreeBSD stack itself for remote communication,
-it will be impossible to debug this stack as a breakpoint in the stack code
-will stop its execution and there would be no more way to communicate with the
-target. A solution consists in implementing a minimal, dedicated UDP/IP stack
-(with at least IP and UDP protocols, a minimal BSD sockets) and a simple SUN
-RPC library, which will be both dedicated to the debug. We can use RTEMS API
-to implement it if @b{(R7)} is not required. As the two stack will need
-to share the same chip, a kind of shared filter must be implemented at the bottom
-of the two stacks so that Ethernet frames can be dynamically directed either
-to the dedicated UDP/IP debug stack or to the regular FreeBSD stack. The fact
-that in the current design, the low level ethernet input routine mainly signal
-a thread should facilitate the design of this filter. The output path is less
-complicated as it is run by a task and thus can sleep on a synchronization object,
-
-@item [(R9)]:
-This requirement represents what we find reasonable as a first target.
-However, we can still present to the final user this kind of debugging via different
-model. RTEMS can be represented as a single threaded system or, because RTEMS
-is a multitasking system, as an ensemble of separate tasks. In the first representation,
-the debugger sees only 1 ``task'' without distinguishing the core executive
-part from the applicative part. This is the simplest way to implement the debugger
-but also implies that there is no way to protect the core executive. Some of
-these tasks are system tasks (tasks form the core executive and from the FreeBSD
-stack), the other ones are tasks implemented by the developer. The developer
-wants to debug his tasks, and sometimes only one of his tasks. We can provide
-a way to debug not the entire system but only the concerned task by testing
-if the current running task is a debugged task (test on the task identifier).
-GDB offers an API to ``detach'' thread so that if a detached thread hits a
-breakpoint it is automatically restarted without user intervention,
-
-@item [(R10)]:
-Several developers can work on a large project, each on a specific
-module. Sometimes only one target is available for everyone. This requirements
-is not really meaningfull until RTEMS supports dynamic code loading,
-
-@item [(R11)]:
-This requirement heavily depends on the @b{(R7)} and @b{(R8)}
-requirements.
-@end table
-
-@section Requirements Selection
-
-
-@subsection Requirement We Will Take Into Account For the First Implementation
-
-@table @b
-
-@item [(R1)]:
-Obviously.
-
-@item [(R2)]:
-As these are our targets. Of course other will be free to contribute.
-We will however document the works that needs to be done in order to port the
-debug code to other processors,
-
-@item [(R3)]:
-We think it is feasible with only few RTEMS modifications,
-
-@item [(R5)]:
-We think serial line debugging is nowadays too restrictive as most equipment
-are now connected via Ethernet,
-
-@item [(R6)]:
-This is a documentation problem and should be fairly easy to describe
-once we have the RGDBSD code,
-
-@item [(R9)]:
-We will try to provide the multi-thread target system presentation,
-@end table
-
-@subsection Requirements We Will Not Implement
-
-@table @b
-
-@item [(R4)]:
-it will not be implemented for the moment. It is just a matter on implementing
-SLIP in the FreeBSD stack and alternative solutions already exist in the meantime,
-
-@item [(R7)]:
-To simplify the first developments, we don't plan to implement a @emph{dedicated}
-nano-kernel to allow the RTEMS kernel to be debugged. It means that, if any
-breakpoint is set in the kernel, unpredictable behaviors can occur. So, developers
-must keep in mind to avoid stopping the kernel. They must also keep in mind,
-in order to not stop the kernel, that the user's tasks must have a lower priority
-than the tasks used for debug. The solution is to use a specific very-high priority
-level for the system tasks used directly or indirectly by RGDBSD. The SYSTEM_TASK
-attribute that already exists should be fine.
-
-@item [(R8)]:
-To avoid increasing the code size and the used memory and because the
-FreeBSD stack doesn't need to be debug any more, we choose not to implement
-a minimal TCP/IP stack but rather to use the FreeBSD one as communication protocol,
-
-@item [(R10)]:
-We will see later when a file system will be available and we can implement
-@b{exec} system call,
-
-@item [(R11)]:
-Without a separate TCP/IP stack it will be hard to freeze the system
-as some interrupts must occur in order to enable the FreeBSD stack to function,
-@end table
-
-@section Implied Restrictions
-
-High priority level must be used for these features :
-
-@itemize @bullet
-
-@item FreeBSD interrupt handling thread,
-
-@item Debugger threads.
-@end itemize
-
-This will allows these tasks not to be stopped when a process is stopped
-in debug mode 
-
-If we don't want to use a ``specific'' priority level, we must affect
-priority to each of these tasks as follow :
-
-@itemize @bullet
-
-@item FreeBSD stack (high priority)
-
-@item Debugger (less high priority)
-@end itemize
-
-The user must remember the higher priority level he can use for his
-software in order not to block one of the previous threads and to not put breakpoints
-in part of the code executed by RGDBSD.

-@chapter Commands
-
-The usual GDB commands are available to display or modify data structures and
-machine registers, disassemble code, display source listings, set and reset
-breakpoints, control the debuggee execution, etc. Refer to Debugging with GDB
-for a complete documentation of the standard GDB commands.
-
-GDB 4.17 has been extended with a number of commands specifically
-for multi-threaded debugging within a RTEMS host-target environment. These commands
-are described in this section.
-
-
-@section Host-target connection control
-
-@itemize @bullet
-@item (gdb) setrpcmode sun : specifies the SUN RPC type.
-@item (gdb) setdaemontype rdbg : specifies the RDBG debug server type.
-@item (gdb) target rtems target-name : specifies the target type.
-@end itemize
-
-@section System status information
-
-@itemize @bullet
-@item (gdb) info threads : gives a list of all threads in the debuggee,
-their names, identifiers and states. It also indicates which thread is
-the target thread.
-@end itemize
-
-
-@section Thread control
-
-@itemize @bullet
-@item (gdb) thread target [id] : allows the user to get/set the target thread.
-The argument id is either the thread's symbolic name or its local identifier.
-@item (gdb) thread detach [id...] : all stops (breakpoints) of some specified
-thread(s) can be ignored using the thread detach command. Each time a detached
-thread hits a breakpoint, RTEMS/GDB will automatically restart the debuggee
-without passing control to the user.
-@item (gdb) thread attach [id...] : (re)attach specified thread(s).
-@end itemize

-@chapter Introduction
-
-GDB 4.17 is a source-level symbolic debugger for RTEMS environment.
-This version is an extension of GNU GDB version 4.17, adapted for the debugging
-of RTEMS applications in a heterogeneous host-target environment.
-
-This paper documents @b{only} the RTEMS/GDB extensions to GNU
-GDB 4.17, as well as its use in the RTEMS environment. The reader is assumed
-to be familiar with GNU GDB.
-
-The RTEMS project would like to thank Emmanuel Raguet (raguet@@crf.canon.fr)
-and Eric Valette (valette@@crf.canon.fr) of the Canon Research Centre 
-France S.A. for developing and documenting RTEMS/GDB and submitting it.

-@chapter Getting Started
-
-This section describes the steps which are necessary to set up a
-debugging session with RTEMS/GDB.
-
-
-@section Compiling The System Components
-
-The components that need to be debugged have to be compiled with the -g option
-in order the generated file to contain the required information for the debug
-session.
-
-
-@section Starting a debugging session
-
-After having launched GDB, the user must connect to the RTEMS target with the
-following commands:
-
-@example
-(gdb) setrpcmode sun
-(gdb) setdaemontype rdbg
-(gdb) target rtems target-name
-@end example
-
-Then he can use the file GDB command to specify the binary to be debugged.
-
-This initialization phase can be written in a @code{``.gdbinit''}
-file. Each time, the user will launch GDB, it will execute this initialization
-sequence.
-
-
-@section Attaching To The System
-
-The entire target system is viewed as a single multi-threaded process,
-the identifier of which is 1. To attach, use:
-
-@example
-(gdb) attach 1
-@end example
-
-When successfully attached, the user can control the execution of
-the target system from the debugger.

-
-RTEMS/GDB host-target debugger is architectured around:
-
-@itemize @bullet
-@item One debugger, running on the host.
-@item One debug server, running on the target.
-@end itemize
-
-The host debugger communicates with the debug server using Sun RPC
-over UDP/IP (Ethernet).
-
-When opening a debugging session, the user takes the control over
-the entire target system. The target system is viewed as a single multi-threaded
-process.
-
-The debugger can observe the state of the system objects, without
-stopping the entire system. However, breakpoints and stepping affect (stop)
-the entire system.
-
-For a given target, only one single system debugging session is possible
-at a time.
