Release notes for GXemul 0.6.0

Copyright (C) 2003-2010 Anders Gavare


GXemul is a framework for full-system computer architecture emulation. Several processor architectures and machine types have been implemented. It is working well enough to allow unmodified "guest" operating systems to run inside the emulator, as if they were running on real hardware.

The emulator emulates (networks of) real machines. The machines may consist of ARM, MIPS, Motorola 88K, PowerPC, and SuperH processors, and various surrounding hardware components such as framebuffers, busses, interrupt controllers, ethernet controllers, disk controllers, and serial port controllers.

The documentation lists the machines and guest operating systems that can be regarded as "working" in GXemul. The best working guest operating system is NetBSD/pmax.


The main change between release 0.4.7.2 and 0.6.0 is:

In addition to the new framework, a couple of other changes are worth mentioning:


Please read the HISTORY file for more details.


Files included in this release are:

    HISTORY                       Detailed revision history / changelog.
    LICENSE                       Copyright message / license.
    README                        Quick start instructions, for the impatient.
    configure, Makefile.skel      sh and make scripts for building GXemul.
    demos/                        Tutorial-like demos of testmachine functionality.
    doc/                          Documentation. (*)
    doc/RELEASE.html              This file.
    doc/TODO                      TODO notes.
    experiments/                  Experimental code. (Usually not needed.)
    man/                          Man page.
    src/                          Source code.
    test/                         Files used for testing.

(*) Note: In general, the documentation refers to how things worked in pre-0.6.0 releases.

To build the emulator, run the configure script, and then run make. This should hopefully work on most Unix-like systems, with few or no modifications to the source code.

Regarding files in the src/include/ directory: only some of these are written by me, the rest are from other sources (such as NetBSD). The license text says that "All advertising materials mentioning features or use of this software" must display acknowledgements. Even though I do not feel that I mention features or use of the header files (the "software") in any advertising materials, I am still very grateful for the fact that these people have made their files available for re-use, as Free software, so regardless of legal requirements, I guess thanking them like this is in order:
