Short: Minimal MuLib archive for redistribution Author: thor@math.tu-berlin.de (Thomas Richter), evogt@free.fr (Etienne Vogt) Uploader: evogt free fr (Etienne Vogt) Type: util/libs Version: 43.10 Requires: Os 2.04, a 68020/68851, 68030, 68040 or 68060 with a working MMU Architecture: m68k-amigaos ----------------------------------------------------------------------------- Notice: This software was initially developped by Thomas Richter. As Thomas' amiga died a few months ago, I agreed with him to take over the development of some of his software packages, including this one. Etienne Vogt, June 2003. ----------------------------------------------------------------------------- Release 43.10 -------------- - Fixed nasty 43.9 exception crashes on 030 systems (and probably 020/881 as well). These crashes were caused by PhxAss default optimizations which converted explicit BRA.W to BRA.S in the exception handler and messed up calculated jumps. The MuLib is now assembled with branch optimization explicitely turned OFF *grunt* Release 43.9 -------------- - Made the mmu.library assemble with PhxAss by decoding DevPac only macros. - Added safeguard to the mmu.library AddMem command for switchable accelerator boards: memory in the 32bit address space (above the first 16Mb) will only be added if the CPU is at least a 68020. - Made the mmu.library ClearMMU command more effective: it will now reset areas incorrectly marked valid in the boot configuration to blank space. - THOR: Added workaround for some Appolo 060 boards that apparently misuse some undocumented 060 MMU table bits. ----------------------------------------------------------------------------- This archive is mainly considered for "re-distribution" within third-party products. In case your software requires the mmu.library, please include this archive unmodified and verbatim somewhere in your software package and include the installation nodes in your documentation. The mmu.library is freeware under my licence conditions stated below, hence if your software is "shareware" or "commercial", feel prepared that I'd like to ask you for one free licence of your software. It took over one year to write this software, to debug it, to write the tools, the documentation, to test it, I even spend some money for additional hardware to develop it. Hence, a lot of work went into this project. It would be nice if I would get some feedback from you. In case you need more documentation, insight, example sources, debugging tools,... please download the full MuLib archive from Aminet: util/libs/MMULib.lha Library to ctrl the MC68K MMUs ----------------------------------------------------------------------------- Purpose and goal of this library: The mmu.library is a basis for MMU (memory management) related functions the MC68K family can perform. Up to now certain hacks are available that program the MMU themselves (Enforcer,CyberGuard,GuardianAngle,SetCPU,Shapeshifter, VMM,GigaMem...). It's therefore not unexpected that these tools conflict with each other. There's up to now no Os support for the MMU at all - the gap this mmu.library fills. The goal is to provide a basis of functions to address and program the MMU in a hardware independent, Os friendly fashion. Hence, the new version of the Enforcer, called MuForce, will work together with virtual memory, and others. The mmu.library is also the basis for a virtual memory project, the memory.library. Even though the mmu.library does not provide virtual memory itself, it builds the basics to allow an easy implementation and to avoid the hacks required by other implementations so far. ------------------------------------------------------------------------------ The THOR/EV-Software Licence (v3, 23th March 2003) This License applies to the computer programs known as "LoadModule" The "Program", below, refers to such program. The "Archive" refers to the package of distribution, as prepared by the authors of the Program, Thomas Richter and Etienne Vogt. Each licensee is addressed as "you". The Program and the data in the archive are freely distributable under the restrictions stated below, but are also Copyright (c) Thomas Richter (upto V40.10) and Etienne Vogt (V40.11 and up). Distribution of the Program, the Archive and the data in the Archive by a commercial organization without written permission from the authors to any third party is prohibited if any payment is made in connection with such distribution, whether directly (as in payment for a copy of the Program) or indirectly (as in payment for some service related to the Program, or payment for some product or service that includes a copy of the Program "without charge"; these are only examples, and not an exhaustive enumeration of prohibited activities). However, the following methods of distribution involving payment shall not in and of themselves be a violation of this restriction: (i) Posting the Program on a public access information storage and retrieval service for which a fee is received for retrieving information (such as an on-line service), provided that the fee is not content-dependent (i.e., the fee would be the same for retrieving the same volume of information consisting of random data). (ii) Distributing the Program on a CD-ROM, provided that a) the Archive is reproduced entirely and verbatim on such CD-ROM, including especially this licence agreement; b) the CD-ROM is made available to the public for a nominal fee only, c) a copy of the CD is made available to the authors for free except for shipment costs, and d) provided further that all information on such CD-ROM is redistributable for non-commercial purposes without charge. Redistribution of a modified version of the Archive, the Program or the contents of the Archive is prohibited in any way, by any organization, regardless whether commercial or non-commercial. Everything must be kept together, in original and unmodified form. Limitations. THE PROGRAM IS PROVIDED TO YOU "AS IS", WITHOUT WARRANTY. THERE IS NO WARRANTY FOR THE PROGRAM, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OF THIRD PARTY RIGHTS.
