==============  RELEASE  ==============

20050609	Adding simple MIPS IPIs (to dev_mp).
20050611	Adding an ugly hack to track down low-reference bugs
		(define TRACE_NULL_CRASHES, or configure --tracenull).
		Other minor updates.
20050612	Adding a dummy evbmips mode.

1 Release notes for GXemul
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. Several
9 emulation modes are available. For some emulation modes, processors and
10 surrounding hardware components are emulated well enough to let unmodified
11 operating systems run as if they were running on a real machine.
13 I have verified that the following "guest" operating systems can run
14 inside the emulator:
16 Guest operating system Emulated machine
17 ---------------------- ----------------
18 NetBSD/pmax 2.0 (and 1.6.2) DECstation 5000/200
19 OpenBSD/pmax 2.8-BETA DECstation 5000/200
20 Ultrix 4.2-4.5 DECstation 5000/200
21 Sprite demo harddisk image DECstation 5000/200
22 Debian GNU/Linux for DECstation DECstation 5000/200
23 Redhat Linux 7.1 for mips DECstation 5000/200
24 NetBSD/arc 1.6.2 Acer PICA-61
25 OpenBSD/arc 2.3 Acer PICA-61
26 NetBSD/hpcmips 2.0 NEC MobilePro 770, 780, 800, 880
27 NetBSD/cobalt 2.0 Cobalt
29 A couple of other emulation modes exist. Some of these modes are almost
30 working well enough to run complete guest operating systems, but most are
31 just skeletons. The modes that work are listed in the documentation.
33 The emulator can also be used in other experiments; it does not have to
34 run entire guest operating systems. It is important to remember, though,
35 that GXemul does not simulate things smaller than an instruction; this
36 means that pipe-line stalls, penalties caused by branch-prediction misses,
37 and other effects are not simulated.
39 Summary of changes between release 0.3.2 and
41 x) When booting from an ISO9660 (CDROM) filesystem image, the kernel
42 can now in some cases be read directly from the image, so there is
43 no need any longer to supply an external kernel. (It is a quick,
44 buggy, and very ugly hack, but it sometimes works.)
46 x) Mixing more than one disk image type (SCSI, IDE, PC-style floppy)
47 within one emulated machine is now possible. (There is however no
48 stable emulation mode yet that uses this.)
50 x) Many minor updates and bugfixes.
52 Files included in this release are:
54 BUGS A list of known bugs.
55 HISTORY Detailed revision history / changelog.
56 LICENSE Copyright message / license.
57 README Quick start instructions, for the impatient.
58 RELEASE This file.
59 TODO TODO notes.
60 configure, Makefile.skel sh and make scripts for building GXemul.
61 doc Documentation.
62 experiments Experimental code. (Usually not needed.)
63 src Source code.
64 tests Regression tests.
66 To build the emulator, run the ./configure script, and then run make.
68 Building the emulator should work on most Unix-like systems. (One system which
69 is specifically known to NOT work is Ultrix/RISC inside the emulator; Ultrix
70 chokes on the configure script and the default cc in Ultrix doesn't work.)
72 Regarding files in the src/include/ directory: only some of these are written
73 by me, the rest are from other sources (such as NetBSD). The license text says
74 that "All advertising materials mentioning features or use of this software"
75 must display acknowledgements. Even though I do NOT feel I mention features or
76 use of the header files (the "software") in any advertising materials, I am
77 still very grateful for the fact that these people have made their files
78 available for re-use, so regardless of legal requirements, I guess thanking
79 them like this is in order:
