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 serial world this makes it important that any buffers on the host + * side are flushed during initialisation of the debugger, and in an + * Ethernet world it makes it important that the target can cope with the + * message not being received. + * + * Eventually the Debugger will be started up and will send an + * ADP_Reboot or ADP_Reset request. The target will respond to this with + * an ADP_Reboot or ADP_Reset acknowldege and will then reboot, finally + * sending an ADP_Rebooted when it has done all it needs to do (very little + * in the case of ADP_Reset, but completely rebooting in the case of + * ADP_Reboot). Note that it is important that an ADP_Rebooted message is + * sent so that the Debugger does not attempt to send any data after it has + * made a request to ADP_Reboot and before it receives an ADP_Rebooted, as + * data can be lost be the target during this time. + * + * The target and host are now ready to start a debug session. + * + * b) Target board is powered up after host debugger is invoked + * + * The debugger will send an ADP_Reboot or ADP_Reset request, but will + * receive no reply until the target is powered up. +/ * + * When the target is powered up then it will send an ADP_Rebooted + * message to the debugger. The debugger should accept this message + * even though it has received no ADP_Reboot or ADP_Reset acknowldege message + * from the target. + * + * The target and host are now ready to start a debug session. + * + * + * If at any point during the bootup sequence and ADP messages are + * sent down the S_DBG channel then they should be responded to with a + * RDI_NotInitialised error.

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.
