Since the relevant header files were not exported - * publicly as part of an ARM Ltd core tools release, it was a problem - * for developers manipulating the target side of the protocol. - * - * For Angel, this new (ANSI 'C' clean) header file defines the ADP - * protocol. The header should be useable by both host and target - * systems, thus avoiding problems that can arise from duplicate - * definitions. Care has been taken in the construction of this header - * file to avoid any host/target differences. - * - * MESSAGE FORMAT - * -------------- - * Format of the "data" section of debug and boot agent messages. This is - * the standard ADP (Angel Debug Protocol) message format: - * - * unsigned32 reason - Main debug reason code. - * unsigned32 debugID - Information describing host debug world; - * - private to host and used in any target initiated - * messages. - * unsigned32 OSinfo1 \ Target OS information to identify process/thread - * unsigned32 OSinfo2 / memory/world, etc. These two fields are target - * defined. - * byte args[n] - Data for message "reason" code. - * - * NOTE: The message format is the same for single threaded debugging, - * except that the "OSinfo" fields should be -1 (0xFFFFFFFF). Even - * single-threaded debugging *MAY* have different host specified - * debugID values, so the Angel debug system will preserve the "debugID" - * information for replies, and the relevant asynchronous target-to-host - * messages. The "debugID" is defined by the host-end of the - * protocol, and is used by the host to ensure that messages are - * routed to the correct handler program/veneer. - * - * The reason there are two target specified "OSinfo" words is because - * thread identifiers may not be unique when processes/tasks have - * private virtual address spaces. It allows more flexibility when - * supporting multi-threaded or O/S aware debugging. - * - * NOTE: The reason that there is no "size" information, is that the - * message IDs themselves encode the format of any arguments. Also it - * would be a duplication of information used by the physical - * transport layer (which is distinct from this logical message - * layer). Any routing of messages through programs, hosts, - * etc. should be performed at the physical layer, or the boundaries - * between physical layers. i.e. packet received on socket in host, - * and transferred to serial packet for passing on down the line. - * - * NOTE: Pointers aren't passed in messages because they are dangerous in - * a multi-threaded environment. - * - * ADP REASON CODE - * --------------- - * The message reason codes contain some information that ties them to - * the channel and direction that the message will be used with. This - * will ensure that even if the message "#define name" is not - * completely descriptive, the message reason code is. - * - * b31 = direction. 0=Host-to-Target; 1=Target-to-Host; - * b30-28 = debug agent multi-threaded control (see below) - * b27-24 = reserved. should be zero. - * b23-16 = channelid. The fixed Angel channel number - * (see "channels.h"). - * b15-0 = message reason code. - * - * It is unfortunate that to aid the error-checking capabilities of - * the Angel communications we have changed the message numbers from - * the original ARM Ltd RDP. However this also has benefits, in that - * the Angel work is meant to be a clean break. - * - * However, it isn't so bad since even though the numbers are - * different, the majority of the reason codes have exactly the same - * functionality as the original RDP messages. - * - * NOTES - * ----- - * It would be ideal to use "rpcgen" (or some equivalent) to - * automatically maintain compatibility between the target and host - * ends of the protocol. However, ARM Ltd expressed that the message - * handling should be hand-coded, to avoid dependance on external - * tools. - * - * All other channels have undefined data formats and are purely - * application defined. The C library "_sys_" support will provide a - * veneer to perform message block operations as required. - * - * It is IMPLIED that all of the ADP messages will fit within the - * buffer DATASIZE. This has a minimum value, calculated from - * BUFFERMINSIZE. - * - * All messages are passed and received to the channel system in little - * endian order (ie. use little endian order when writing a word as - * a sequence of bytes within a message). - * - * A reply / acknowledgement to an ADP message is always sent and has the - * same reason code as the original except that the TtoH / HtoT bit is - * reversed. This makes it simple to check that the reply really - * is a reply to the message which was just sent!

In a true commercial target, this code should be - * re-designed to build a system where the Angel logical message - * system, device driver and hardware accesses are merged to provide - * the best performance. - */ -/*---------------------------------------------------------------------------*/ -/* Angel overview: - -... some comments describing Angel ... - - * Angel is designed as a kit-of-parts that can be used to provide - * run-time support for the development of ARM applications. The main - * core of Angel is in providing support for the "debug" message - * communication with a host system. These messages do not just cover - * debugging ARM processes, but also the process of downloading ARM - * programs or attaching to executing processes on the target. - * - * A stand-alone ROM based Angel world is the basic starting point for - * a system, since it will allow programs to be downloaded to the - * target. The ROM version of Angel will provide the generic debug - * support, but no system specific routines. The preferred method of - * using Angel is as a link library. This ensures that applications - * carry with them the Angel routines necessary to support debugging - * (and also ensure that the Angel version is up-to-date, independant - * of the version in the target ROM). Eventually, once a program has - * been fully debugged, a ROMmed version of the program can be - * generated with the Angel code being provided in the application. - -.. more comments .. - - * The standard Angel routines do *NOT* perform any dynamic memory - * allocation. To simplify the source, and aid the porting to a non C - * library world, memory is either pre-allocated (as build-time - * globals) or actually given to the particular Angel routine by the - * active run-time. This ensures that the interaction between Angel - * and the target O/S is minimised. - * - * Notes: We sub-include more header files to keep the source - * modular. Since Angel is a kit-of-parts alternative systems may need - * to change the prototypes of particular functions, whilst - * maintaining a fixed external interface. e.g. using the standard - * DEBUG messages, but with a different communications world. - */ -/*---------------------------------------------------------------------------*/ - -#ifndef __angel_h -#define __angel_h - -/*---------------------------------------------------------------------------*/ -/*-- Global Angel definitions and manifests ---------------------------------*/ -/*---------------------------------------------------------------------------*/ -/* When building Angel we may not include the standard library - * headers.
