1 Release notes for GXemul 0.3.4
2 ==============================

4 Copyright (C) 2003-2005 Anders Gavare.

7 GXemul is an experimental instruction-level machine emulator. It can be
8 used to run binary code for (among others) MIPS-based machines, regardless
9 of host platform. Several emulation modes are available. For some modes,
10 processors and surrounding hardware components are emulated well enough to
11 let unmodified operating systems (e.g. NetBSD) run as if they were running
12 on a real machine.
13
14 I have verified that the following "guest" operating systems can run
15 inside the emulator:
16
17 Guest operating system Emulated machine
18 ---------------------- ----------------
19 NetBSD/pmax 2.0.2 (and 1.6.2) DECstation 5000/200
20 OpenBSD/pmax 2.8-BETA DECstation 5000/200
21 Ultrix 4.2-4.5 DECstation 5000/200
22 Sprite demo harddisk image DECstation 5000/200
23 Debian GNU/Linux for DECstation DECstation 5000/200
24 Redhat Linux 7.1 for mips DECstation 5000/200
25 NetBSD/arc 1.6.2 Acer PICA-61
26 OpenBSD/arc 2.3 Acer PICA-61
27 NetBSD/hpcmips 2.0.2 NEC MobilePro 770, 780, 800, 880
28 NetBSD/cobalt 2.0.2 Cobalt
29 NetBSD/evbmips 2.0.2 Malta 5Kc/4Kc evaluation board
30 NetBSD/sgimips 2.0.2 SGI O2 ("IP32")
31
32 Some of these guest operating systems are easier to install and run than
33 others. The best supported mode is the DECstation 5000/200 emulation mode,
34 with NetBSD/pmax as the guest operating system.
35
36 A couple of other emulation modes exist. Some of these modes are almost
37 working well enough to run complete guest operating systems, but most are
38 just skeletons. The modes that work are listed in the documentation.
39
40 The emulator can also be used in other experiments; it does not have to
41 run entire guest operating systems. (However, GXemul does not simulate
42 things smaller than an instruction. What this means is that pipe-line
43 stalls, penalties caused by branch-prediction misses or cache misses, and
44 other micro-architectural effects are not simulated.)
45
46 Summary of changes between release 0.3.3.2 and 0.3.4:
47
48 x) When emulating a network of multiple machines, the emulated
49 machines can now be placed on different hosts.
50
51 x) NetBSD/evbmips can now be installed and run from a disk image.
52 (There is no INSTALL kernel for NetBSD/evbmips, so you need to
53 install using another OS, for example emulated NetBSD/pmax.)
54
55 x) NetBSD/sgimips can now be installed. Not onto a SCSI disk,
56 but the files can be exported via nfs from another emulated
57 machine. The sgimips machine can then netboot. (Read the
58 documentation for details.)
59
60 There have also been various other minor updates and bugfixes.
61
62 Files included in this release are:
63
64 BUGS A list of known bugs.
65 HISTORY Detailed revision history / changelog.
66 LICENSE Copyright message / license.
67 README Quick start instructions, for the impatient.
68 RELEASE This file.
69 TODO TODO notes.
70 configure, Makefile.skel sh and make scripts for building GXemul.
71 doc Documentation.
72 experiments Experimental code. (Usually not needed.)
73 src Source code.
74 tests Regression tests.
75
76 To build the emulator, run the ./configure script, and then run make.
77
78 Building the emulator should work on most Unix-like systems. (One system which
79 is specifically known to NOT work is Ultrix/RISC inside the emulator; Ultrix
80 chokes on the configure script and the default cc in Ultrix doesn't work.)
81
82 Regarding files in the src/include/ directory: only some of these are written
83 by me, the rest are from other sources (such as NetBSD). The license text says
84 that "All advertising materials mentioning features or use of this software"
85 must display acknowledgements. Even though I do NOT feel I mention features or
86 use of the header files (the "software") in any advertising materials, I am
87 still very grateful for the fact that these people have made their files
88 available for re-use, so regardless of legal requirements, I guess thanking
89 them like this is in order:
