Short: Update the MuLib 40.5x -> 40.60
Uploader: thor@math.tu-berlin.de (Thomas Richter)
Author: thor@math.tu-berlin.de (Thomas Richter)
Type: util/libs
Requires: Os 2.04, a 68020/68851, 68030, 68040 or 68060 with a working MMU
Version: 40.51.1
This is an upgrade package for the MMULib 40.5x to 40.60. The 40.5x package
must have been downloaded already, I *will not* re-upload the complete 40.5x
packages for a minor release change. Please get the 40.5x packages first,
then download this archive.
-----------------------------------------------------------------------------
Release 40.60
-------------
- fixed the shutdown code of MGA, thanks to Stephan!
- disabled a kludge in the mmu.library which write protected
a kickstart image at 0x00200000 and up by checking the name
of execbase. This kludge might have conflicted with some softkickers.
- Because people tend not to read guides, I added the
arguments "WRITEPROTECTED" and "INVALID" to the library build-in
"SetCacheMode". Note that they work different to what "MuSetCacheMode"
does. Here, "WRITEPROTECTED" and "INVALID" are just aliases to "ROM"
and "BLANK", hence enable the most defensive protection strategy.
- Added a new LVO "RebuildTreesA" which is "officially" not yet
existing and will be documented in V41. More LVOs might be added up
to V41, but please *DO NOT* yet call them as they did not exist
in V40.50.
- Fixed the installation script, due to a typo the P5 MMU boot hack
was not detected.
- Fixed the P5Detect program which just looked to the wrong
identification resources. Ooops. Installation on "non-standard"
boards should be smoother now.
- Fixed a bug in the disassembler.library which disassembled the
lea (offset.L,pc)
wrong. The offset was wrong by two bytes.
- The release number in the MuForce guide was wrong.
- When will people finally learn to read the FAQ? *Sigh*
In case MuFastZero complains "The zero page is already remapped",
---> READ THE GUIDE. <---
-----------------------------------------------------------------------------
The MuLib and related tools are intrinsically incompatible to the ppc.library.
I would have supported the ppc.library if I would have had some internal
information about it. Unfortunately, P5 denies to hand them out. Sorry.
-----------------------------------------------------------------------------
Purpose and goal of this library:
The mmu.library is a planned 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
is planned to fill.
The goal is to provide a basis of functions to address and program the MMU in
a hardware independent, Os friendly fashion. Hence, a future version of the
Enforcer 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-Software Licence (v2, 24th June 1998)
This License applies to the computer programs known as the "mmu.library"
and its sources. The "Program", below, refers to such program. The
"Archive" refers to the package of distribution, as prepared by the author
of the Program, Thomas Richter. 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)

Distribution of the Program, the Archive and the data in the Archive by a
commercial organization without written permission from the author 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 author 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. THE ENTIRE
RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD
THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.
IF YOU DO NOT ACCEPT THIS LICENCE, YOU MUST DELETE THE PROGRAM, THE ARCHIVE
AND ALL DATA OF THIS ARCHIVE FROM YOUR STORAGE SYSTEM. YOU ACCEPT THIS
LICENCE BY USING OR REDISTRIBUTING THE PROGRAM.
