20050617	Experimenting some more with netbooting OpenBSD/sgi. Adding
		a hack which allows emulated ethernet networks to be
		distributed across multiple emulator processes.
20050618	Minor updates (documentation, dummy YAMON emulation, etc).
20050620	strcpy/strcat -> strlcpy/strlcat updates.
		Some more progress on evbmips (Malta).
20050621	Adding a section to doc/configfiles.html about ethernet
		emulation across multiple hosts.
		Beginning the work on the ARM translation engine (using the
		dynamic-but-not-binary translation method).
		Fixing a bintrans bug: 0x9fc00000 should always be treated as
		PROM area, just as 0xbfc00000 is.
		Minor progress on Malta emulation (the PCI-ISA bus).
20050622	NetBSD/evbmips can now be installed (using another emulated
		machine) and run (including userland and so on). :-)
		Spliting up the bintrans haddr_entry field into two (one for
		read, one for write). Probably not much of a speed increase,
		Updating some NetBSD 2.0 -> 2.0.2 in the documentation.
20050623	Minor updates (documentation, the TODO file, etc).
		gzipped kernels are now always automagically gunzipped when
20050624	Adding a dummy Playstation Portable (PSP) mode, just barely
		enough to run Hello World (in weird colors :-).
		Removing the -b command line option; old bintrans is enabled
		by default instead. It makes more sense.
		Trying to finally fix the non-working performance measurement
		thing (instr/second etc).
20050625	Continuing on the essential basics for ARM emulation. Two
		instructions seem to work, a branch and a simple "mov". (The
		mov arguments are not correct yet.) Performance is definitely
		Various other minor updates.
		Adding the ARM "bl" instruction.
		Adding support for combining multiple ARM instructions into one
		function call. ("mov" + "mov" is the only one implemented so
		far, but it seems to work.)
		Cleaning up some IP32 interrupt things (crime/mace); disabling
		the PS/2 keyboard controller on IP32, so that NetBSD/sgimips
		boots into userland again.
20050626	Finally! NetBSD/sgimips netboots. Adding instructions to
		doc/guestoses.html on how to set up an nfs server etc.
		Various other minor fixes.
		Playstation Portable ".pbp" files can now be used directly.
		(The ELF part of the .pbp is extracted transparently.)
		Converting some sprintf -> snprintf.
		Adding some more instructions to the ARM disassembler.
20050627	More ARM updates. Adding some simple ldr(b), str(b),
		cmps, and conditional branch instructions, enough to run
		a simple Hello World program.
		All ARM instructions are now inlined/generated for all possible
		condition codes.
		Adding add and sub, and more load/store instructions.
		Removing dummy files: cpu_alpha.c, cpu_hppa.c, and cpu_sparc.c.
		Some minor documentation updates; preparing for a 0.3.4
		release. Updating some URLs.

1 dpavlin 10 Release notes for GXemul 0.3.4
2     ==============================
3 dpavlin 2
4     Copyright (C) 2003-2005 Anders Gavare.
7     GXemul is an experimental instruction-level machine emulator. It can be
8 dpavlin 10 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 dpavlin 2
14     I have verified that the following "guest" operating systems can run
15     inside the emulator:
17     Guest operating system Emulated machine
18     ---------------------- ----------------
19 dpavlin 10 NetBSD/pmax 2.0.2 (and 1.6.2) DECstation 5000/200
20 dpavlin 2 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 dpavlin 10 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 dpavlin 2
32 dpavlin 10 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.
36 dpavlin 2 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.
40     The emulator can also be used in other experiments; it does not have to
41 dpavlin 10 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 dpavlin 2
46 dpavlin 10 Summary of changes between release and 0.3.4:
47 dpavlin 2
48 dpavlin 10 x) When emulating a network of multiple machines, the emulated
49     machines can now be placed on different hosts.
50 dpavlin 2
51 dpavlin 10 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 dpavlin 2
55 dpavlin 10 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 dpavlin 6
60 dpavlin 10 There have also been various other minor updates and bugfixes.
62 dpavlin 2 Files included in this release are:
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 dpavlin 4 configure, Makefile.skel sh and make scripts for building GXemul.
71 dpavlin 2 doc Documentation.
72     experiments Experimental code. (Usually not needed.)
73 dpavlin 4 src Source code.
74 dpavlin 2 tests Regression tests.
76     To build the emulator, run the ./configure script, and then run make.
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.)
82 dpavlin 4 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 dpavlin 2 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:
