Release notes for Gavare's eXperimental Emulator (GXemul), 0.4.2
================================================================

Copyright (C) 2003-2006  Anders Gavare.


GXemul is an experimental instruction-level machine emulator. Several
emulation modes are available. In some modes, processors and surrounding
hardware components are emulated well enough to let unmodified operating
systems (e.g. NetBSD) run as if they were running on a real machine.

The documentation lists the machines and guest operating systems that can 
be regarded as "working" in GXemul. The best working guest operating 
systems are probably NetBSD/pmax, NetBSD/cats, and OpenBSD/cats.


Changes between release 0.4.1 and 0.4.2 include, among other things:

    o)  The NetWinder emulation mode now works well enough to let
        NetBSD/netwinder run from a disk image.

        (NetBSD/netwinder has to be installed manually, though, because
        there is no installation ramdisk kernel. The GXemul documentation
        has an example of how to install NetBSD/netwinder using an emulated
        NetBSD/pmax machine.)

    o)  Algorithmics P5064 emulation works well enough to let NetBSD/algor
        run from a disk image. (Similar to NetBSD/netwinder, it has to
        be installed manually, using another emulated machine.)

    o)  PCI configuration register writes can now be handled, which allows
        NetBSD/Malta (evbmips) 3.0.1 and NetBSD/cobalt 3.0.1 to run from
        PCI IDE harddisk images. (Previously, only NetBSD 2.1 worked for
        the Malta and Cobalt emulation modes.)

    o)  Some performance increases:

        The virtual translation table update routine has been simplified
        to work the same way for 32-bit and 64-bit emulation, and this
        apparently results in a speedup for all 64-bit modes.

        For 32-bit MIPS, some more instruction combinations have been added.

Please read the HISTORY files 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.
  RELEASE                     This file.
  TODO                        TODO notes.
  configure, Makefile.skel    sh and make scripts for building GXemul.
  demos                       Tutorial-like demos of testmachine functionality.
  doc                         Documentation.
  experiments                 Experimental code. (Usually not needed.)
  src                         Source code.

To build the emulator, run the configure script, and then run make. This 
should work on most Unix-like systems.


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 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, so regardless of legal requirements, I guess thanking
them like this is in order:
