20050816	Some success in decoding the way the SGI O2 PROM draws graphics
		during bootup; lines/rectangles and bitmaps work, enough to
		show the bootlogo etc. :-)
		Adding more PPC instructions, and (dummy) BAT registers.
20050817	Updating the pckbc to support scancode type 3 keyboards
		(required in order to interact with the SGI O2 PROM).
		Adding more PPC instructions.
20050818	Adding more ARM instructions; general register forms.
		Importing armreg.h from NetBSD (ARM cpu ids). Adding a (dummy)
		CATS machine mode (using SA110 as the default CPU).
		Continuing on general dyntrans related stuff.
20050819	Register forms for ARM load/stores. Gaah! The Compaq C Compiler
		bug is triggered for ARM loads as well, not just PPC :-(
		Adding full support for ARM PC-relative load/stores, and load/
		stores where the PC register is the destination register.
		Adding support for ARM a.out binaries.
20050820	Continuing to add more ARM instructions, and correcting some
		bugs. Continuing on CATS emulation.
		More work on the PPC stuff.
20050821	Minor PPC and ARM updates. Adding more machine types.
20050822	All ARM "data processing instructions" are now generated
		automatically.
20050824	Beginning the work on the ARM system control coprocessor.
		Adding support for ARM halfword load/stores, and signed loads.
20050825	Fixing an important bug related to the ARM condition codes.
		OpenBSD/zaurus and NetBSD/netwinder now print some boot
		messages. :)
		Adding a dummy SH (Hitachi SuperH) cpu family.
		Beginning to add some ARM virtual address translation.
		MIPS bugfixes: unaligned PC now cause an ADEL exception (at
		least for non-bintrans execution), and ADEL/ADES (not
		TLBL/TLBS) are used if userland tries to access kernel space.
		(Thanks to Joshua Wise for making me aware of these bugs.)
20050827	More work on the ARM emulation, and various other updates.
20050828	More ARM updates.
		Finally taking the time to work on translation invalidation
		(i.e. invalidating translated code mappings when memory is
		written to). Hopefully this doesn't break anything.
20050829	Moving CPU related files from src/ to a new subdir, src/cpus/.
		Moving PROM emulation stuff from src/ to src/promemul/.
		Better debug instruction trace for ARM loads and stores.
20050830	Various ARM updates (correcting CMP flag calculation, etc).
20050831	PPC instruction updates. (Flag fixes, etc.)
20050901	Various minor PPC and ARM instruction emulation updates.
		Minor OpenFirmware emulation updates.
20050903	Adding support for adding arbitrary ARM coprocessors (with
		the i80321 I/O coprocessor as a first test).
		Various other ARM and PPC updates.
20050904	Adding some SHcompact disassembly routines.
20050907	(Re)adding a dummy HPPA CPU module, and a dummy i960 module.
20050908	Began hacking on some Apple Partition Table support.
20050909	Adding support for loading Mach-O (Darwin PPC) binaries.
20050910	Fixing an ARM bug (Carry flag was incorrectly updated for some
		data processing instructions); OpenBSD/cats and NetBSD/
		netwinder get quite a bit further now.
		Applying a patch to dev_wdc, and a one-liner to dev_pcic, to
		make them work better when emulating new versions of OpenBSD.
		(Thanks to Alexander Yurchenko for the patches.)
		Also doing some other minor updates to dev_wdc. (Some cleanup,
		and finally converting to devinit, etc.)
20050912	IRIX doesn't have u_int64_t by default (noticed by Andreas
		<avr@gnulinux.nl>); configure updated to reflect this.
		Working on ARM register bank switching, CPSR vs SPSR issues,
		and beginning the work on interrupt/exception support.
20050913	Various minor ARM updates (speeding up load/store multiple,
		and fixing a ROR bug in R(); NetBSD/cats now boots as far as
		OpenBSD/cats).
20050917	Adding a dummy Atmel AVR (8-bit) cpu family skeleton.
20050918	Various minor updates.
20050919	Symbols are now loaded from Mach-O executables.
		Continuing the work on adding ARM exception support.
20050920	More work on ARM stuff: OpenBSD/cats and NetBSD/cats reach
		userland! :-)
20050921	Some more progress on ARM interrupt specifics.
20050923	Fixing linesize for VR4121 (patch by Yurchenko). Also fixing
		linesizes/cachesizes for some other VR4xxx.
		Adding a dummy Acer Labs M1543 PCI-ISA bridge (for CATS) and a
		dummy Symphony Labs 83C553 bridge (for Netwinder), usable by 
		dev_footbridge.
20050924	Some PPC progress.
20050925	More PPC progress.
20050926	PPC progress (fixing some bugs etc); Darwin's kernel gets
		slightly further than before.
20050928	Various updates: footbridge/ISA/pciide stuff, and finally
		fixing the VGA text scroll-by-changing-the-base-offset bug.
20050930	Adding a dummy S3 ViRGE pci card for CATS emulation, which
		both NetBSD and OpenBSD detects as VGA.
		Continuing on Footbridge (timers, ISA interrupt stuff).
20051001	Continuing... there are still bugs, probably interrupt-
		related.
20051002	More work on the Footbridge (interrupt stuff).
20051003	Various minor updates. (Trying to find the bug(s).)
20051004	Continuing on the ARM stuff.
20051005	More ARM-related fixes.
20051007	FINALLY! Found and fixed 2 ARM bugs: 1 memory related, and the
		other was because of an error in the ARM manual (load multiple
		with the S-bit set should _NOT_ load usermode registers, as the
		manual says, but it should load saved registers, which may or
		may not happen to be usermode registers).
		NetBSD/cats and OpenBSD/cats seem to install fine now :-)
		except for a minor bug at the end of the OpenBSD/cats install.
		Updating the documentation, preparing for the next release.
20051008	Continuing with release testing and cleanup.

82     <h3>General notes on running "guest OSes":</h3>
83    
84     The emulator works well enough to run complete operating systems. These
85     are often refered to as "guest" operating systems.
86    
87     <p>
88     Although it is possible to let a guest OS access real hardware, such as
89     harddisks, it is much more flexible and attractive to simulate harddisks
90     using files residing in the host's filesystem. On Unix-like systems, files
91     may contain holes, which makes this really simple. To the guest operating
92     system, the harddisk image looks and acts like a real disk.

108 dpavlin 4
109 dpavlin 10 <p>To install <a href="http://www.netbsd.org/Ports/pmax/">NetBSD/pmax</a>
110     onto a harddisk image in the emulator, follow these instructions:
111 dpavlin 2
112 dpavlin 10 <p><ol start="1">
113 dpavlin 2 <li>Create an empty harddisk image, which will be the root disk
114     that NetBSD installs itself onto:<pre>
115 dpavlin 12 <b>dd if=/dev/zero of=nbsd_pmax.img bs=1 count=512 seek=1900000000</b>
116 dpavlin 2
117     </pre>
118     </ol>
119 dpavlin 4
120 dpavlin 2 <p>
121     From this point, there are two separate ways to continue the installation.
122     You can either download a CD-ROM iso image (and let the installation
123     program copy files from the CD-ROM image to the harddisk image), or you
124     can install via ftp. For an installation from a CD-ROM image, follow these
125     steps:
126     <p>
127     <ol start="2">
128    
129     <li>Download a NetBSD CD-ROM iso image:<pre>
130     <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/1.6.2/pmaxcd.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/1.6.2/pmaxcd.iso</a>
131     or
132 dpavlin 10 <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/2.0.2/pmaxcd.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/2.0.2/pmaxcd.iso</a>
133 dpavlin 2
134     </pre>
135     <li>Start the emulator like this:<pre>
136 dpavlin 12 <b>gxemul -e 3max -A -d nbsd_pmax.img -d bc:pmaxcd.iso</b>
137 dpavlin 2 </pre>
138 dpavlin 10 and proceed like you would do if you were installing NetBSD on a real
139 dpavlin 12 DECstation. Remember to choose <tt>vt100</tt> as your terminal
140     type, and not <tt>rcons</tt>.
141 dpavlin 2 </ol>
142     <p>
143     For an ftp install, substitute steps 2 and 3 above with these:
144     <p>
145     <ol start="2">
146    
147 dpavlin 10 <li>Download a NetBSD pmax INSTALL kernel:<pre>
148 dpavlin 2 <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-1.6.2/pmax/binary/kernel/netbsd-INSTALL.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-1.6.2/pmax/binary/kernel/netbsd-INSTALL.gz</a>
149     or

151 dpavlin 2
152     </pre>
153     <li>Start the emulator like this:<pre>
154 dpavlin 12 <b>gxemul -e 3max -A -d nbsd_pmax.img -O netbsd-INSTALL.gz</b>
155 dpavlin 2 </pre>
156 dpavlin 10 and proceed like you would do if you were installing NetBSD on a real
157 dpavlin 12 DECstation. Remember to choose <tt>vt100</tt> as your terminal
158     type, and not <tt>rcons</tt>. Suitable networking parameters are as
159     follows:<pre>
160 dpavlin 2 Which device shall I use? [le0]: <b>le0</b>
161     ..
162     Your DNS domain: <b>mydomain.com</b>
163     Your host name: <b>foo</b>
164     Your IPv4 number: <b>10.0.0.1</b>
165     IPv4 Netmask [0xff000000]: <b>0xff000000</b>
166     IPv4 gateway: <b>10.0.0.254</b>
167     IPv4 name server: <b>10.0.0.254</b>
168     </pre>
169 dpavlin 10 (If using 10.0.0.254 as the nameserver fails, then try entering the
170     IP number of a real-world nameserver instead.)
171     </ol>
172 dpavlin 2
173 dpavlin 12 <p>If you want to use a graphical framebuffer during the install, you can
174     add <b><tt>-X -Y2</tt></b> to the command line, and choose <tt>rcons</tt>
175     instead of <tt>vt100</tt> when prompted with which terminal type to use.
176     (By just using <tt><b>-X</b></tt>, you will get a full-size framebuffer
177     window.)
178 dpavlin 2
179 dpavlin 12 <p>When the installation is finished, the following command should start
180 dpavlin 2 NetBSD from the harddisk image:<pre>
181 dpavlin 12 <b>gxemul -e 3max -d nbsd_pmax.img</b>
182 dpavlin 2 </pre>
183    
184 dpavlin 12 <p><font color="#ff0000">NOTE:</font> For some reason, NetBSD 2.0.2
185     doesn't work with X out-of-the-box on pmax. It seems that this has to do
186     with NetBSD switching console system to "WSCONS" somewhere between 1.6.2
187     and 2.0. For now, if you want X, then try NetBSD 1.6.2.
188 dpavlin 2
189 dpavlin 12 <p>With NetBSD/pmax 1.6.2, try the following to start with a framebuffer:<pre>
190     <b>gxemul -X -e 3max -d nbsd_pmax.img</b>
191 dpavlin 2 </pre>
192 dpavlin 12 and log in as <tt>root</tt> and type <tt>startx</tt> to start X windows.

346     <p>
347     <ol start="1">

362 dpavlin 6 -d b:hpcmipscd.iso -j hpcmips/installation/netbsd.gz</b>
363 dpavlin 2
364     </pre>
365     and proceed like you would do if you were installing NetBSD on a real
366 dpavlin 12 MobilePro 770. (Install onto wd0, choose "Use entire disk" when
367 dpavlin 2 doing the MBR partitioning, and choose wd1d (not cd0c) as the
368     CDROM device to install from.)
369     </ol>
370    
371     <p>
372     If everything worked, NetBSD should now be installed on the disk image.
373 dpavlin 12 Use the following command line to boot the emulated hpcmips machine:<pre>
374     <b>gxemul -e mobilepro770 -X -d nbsd_hpcmips.img netbsd-GENERIC.gz</b>

377    
378 dpavlin 12 <p>If you change your mind at this point regarding which machine type to
379     emulate, you might for example prefer a MobilePro 800, then you can change
380     that at any time. NetBSD/hpcmips is designed to be able to boot on many
381     types, without any need to change the kernel.

383 dpavlin 12 <p>When you have logged in as <tt>root</tt>, you can use <tt>startx</tt> to
384     start X Windows, but there is no mouse support yet so only keyboard input

526 dpavlin 12 <p>Note 1: NetBSD detects a very fast CPU although the emulation isn't

531     (MIPS64) CPU, add <tt><b>-C 4Kc</b></tt> to the command line. With NetBSD
532 dpavlin 12 2.0.2, however, there will be little or no difference in functionality, as
533     NetBSD still runs in 32-bit mode on 64-bit MIPS CPUs. The only difference
534     it makes in practice is that GXemul's binary translation subsystem might
535     run a bit faster (because there are some optimizations for 32-bit

730     For example, when NetBSD says "<tt>nfs_boot: trying DHCP/BOOTP</tt>",
731     there will be a long pause, even on a very fast host machine. The reason
732     for this is mostly because the emulator doesn't deal with timing issues

799 dpavlin 2 before continuing here. If you have never installed OpenBSD on any

810     <p>
811 dpavlin 2 OpenBSD/pmax died at release 2.8 of OpenBSD, so you should be
812     aware of the fact that this will not give you an up-to-date OpenBSD
813     system.
814    
815     <p>
816     Following these instructions <i>might</i> work. If not, then use
817     common sense and imagination to modify them as you see fit.
818

837 dpavlin 2 <li>You now need to make an ISO image of the entire directory you downloaded.
838 dpavlin 10 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
839 dpavlin 6 already have <tt>mkisofs</tt> installed on your system, you need
840 dpavlin 10 to install it in order to do this.)<pre>
841 dpavlin 12 <b>mkisofs -o openbsd_pmax_2.8.iso ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax</b>
842 dpavlin 2
843     </pre>
844     <li>Start the emulator with all three (!) disk images:<pre>

846 dpavlin 2
847     </pre>
848 dpavlin 12 (If you add <tt>-X</tt>, you will run with the graphical
849 dpavlin 6 framebuffer. This is <i>REALLY</i> slow because the console has to
850     scroll a lot during the install. I don't recommend it.)
851 dpavlin 2 <p>
852     <li>Go on with the installation as you would do if you were installing on a real machine.
853     If you are not used to the OpenBSD installer, then this will most likely
854     be a very uncomfortable experience. Some important things to keep in mind are:
855     <ul>
856     <li>rz0 is the rootdisk you wish to install onto.
857     <li>rz1 is the simpleroot image.
858     <li>rz2 is the CDROM containing the "install sets".
859     <li>When asked for the "<b>root device?</b>", enter <b>rz1</b>.
860     <li>At "<b>Enter pathname of shell or RETURN for sh:</b>", press enter.
861     <li>At the # prompt, do the following:<pre>
862 dpavlin 12 <b>fsck /dev/rz1a</b> (and mark the filesystem as clean)
863     <b>mount /dev/rz1a /</b>
864     <b>mount -t kernfs kern kern</b>
865     <b>./install</b>
866 dpavlin 2
867     </pre>
868     and proceed with the install. Good luck. :-)
869     <li>Answer "<b>y</b>" when asked if you wish to configure the network.
870     (See the section about installing NetBSD/pmax for suitable
871     network settings.)
872     <li>Install from "<b>c</b>" (cdrom), choose "<b>rz2</b>" as the cdrom device, and "<b>/</b>" as
873     the directory containing the install sets.
874     </ul>
875     <p>
876 dpavlin 10 <li>For some unknown reason, the install script does not set the root
877     password! The first time you boot up OpenBSD after the install, you
878     need to go into single user mode and run <b>passwd root</b> to set
879     the root password, or you will not be able to log in at all!<pre>
880 dpavlin 12 <b>gxemul -e 3max -A -d obsd_pmax.img -d 2c:openbsd_pmax_2.8.iso -j bsd -o '-s'</b>
881 dpavlin 2 </pre>
882     While you are at it, you might want to extract the X11 install sets
883     as well, as the installer seems to ignore them too. (Perhaps due to a bug
884     in the installer, perhaps because of the way I used mkisofs.)
885     <p>
886     Execute the following commands in the emulator:
887 dpavlin 12 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
888     <b>fsck /dev/rz0a

895     ln -s /dev/fb0 /dev/mouse
896     echo /usr/X11R6/lib &gt;&gt; /etc/ld.so.conf

899 dpavlin 12 sync
900     halt</b>
901     </pre></td></tr></table>
902 dpavlin 2 </ol>
903    
904     <p>
905     NOTE: It is also possible to install via ftp instead of using a CDROM image.
906     This is not much less awkward, you still need the simpleroot filesystem
907     image, and you still have to manually add the X11 install sets and set the
908     root password, and so on.
909    
910     <p>
911     Once you have completed the installation procedure, the following command
912     will let you boot from the new rootdisk image:
913     <pre>
914 dpavlin 12 <b>gxemul -e 3max -X -M64 -o '-aN' -d obsd_pmax.img -j bsd</b>
915 dpavlin 2 </pre>
916    
917     <p>
918 dpavlin 6 (Normally, you would be asked about which root device to use (<tt>rz0</tt>),
919     but using <b><tt>-o '-aN'</tt></b> supresses that.)
920 dpavlin 2
921     <p>
922     When asked for which terminal type to use, when logging in as root,
923 dpavlin 6 enter <b><tt>rcons</tt></b> if you are using the graphical framebuffer,
924     <b><tt>vt100</tt></b> for text-mode.
925     <br>Use <b><tt>startx</tt></b> to start X windows.

1078 dpavlin 10 <h3>Ultrix/RISC:</h3>
1079 dpavlin 2
1080 dpavlin 4 Ultrix 4.x can run in GXemul on an emulated DECstation 5000/200.
1081 dpavlin 10 (Ultrix was the native OS for these machines, but NetBSD/pmax is
1082     also usable.)
1083 dpavlin 2
1084 dpavlin 4 <p>
1085     &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
1086     <a href="20040504-ultrix45-boot1.png"><img src="20040504-ultrix45-boot1_small.gif"></a>

1089    
1090     <p>
1091     The following instructions should let you install Ultrix onto a disk image:
1092    
1093 dpavlin 2 <ol>
1094     <li>Create an empty harddisk image, which will be the root disk
1095     that Ultrix installs itself onto:<pre>
1096 dpavlin 12 <b>dd if=/dev/zero of=rootdisk.img bs=1024 count=1 seek=800000</b>
1097 dpavlin 2
1098     </pre>
1099 dpavlin 6 <li>Place your Ultrix installation media in your CDROM drive.
1100     (On FreeBSD and similar systems, it is called <tt>/dev/cd0c</tt>.
1101     Replace that with the name of your CDROM drive, or the name of a
1102     .iso image file.) Then, start the emulator like this:<pre>
1103 dpavlin 12 <b>gxemul -X -A -M64 -e 3max -d rootdisk.img -d bc:/dev/cd0c -j vmunix</b>
1104 dpavlin 2
1105     </pre>
1106     <li>Once the first stage of the installation is done (restoring the root
1107     filesystem), you need to restart the emulator, booting from the
1108     new rootdisk, to continue the installation process.
1109 dpavlin 6 This is done by removing the bootflag ('<tt>b</tt>') from the second
1110 dpavlin 2 diskimage argument:<pre>
1111 dpavlin 12 <b>gxemul -X -A -M64 -e 3max -d rootdisk.img -d c:/dev/cd0c -j vmunix</b>
1112 dpavlin 2
1113     </pre>
1114     </ol>
1115    
1116     <p>
1117     When the installation is completed, the following command should start
1118     Ultrix from the harddisk image:<pre>
1119 dpavlin 12 <b>gxemul -X -A -M64 -e 3max -j vmunix -d rootdisk.img</b>
1120 dpavlin 2 </pre>
1121    
1122 dpavlin 10 <p>Ultrix mostly seems to work with dynamic binary translation (which can
1123     be disabled by the <b><tt>-B</tt></b> command line option). If you have a
1124     very fast host machine, and use bintrans, you might experience a weird
1125     timer related bug, which makes it impossible to logon to the system. It is
1126     triggered when the emulation goes faster than any real DECstation machine
1127     was capable of running. A temporary workaround is to add
1128     <b><tt>-I33000000</tt></b> to fix the emulated clock speed to 33 million
1129     instructions per emulated second. (When using <tt><b>-CR4400</b></tt>,
1130     <b><tt>-I16000000</tt></b> should be used instead.)
1131 dpavlin 2
1132     <p>
1133 dpavlin 6 You can experiment with adding <b><tt>-Z2</tt></b> (for emulating a
1134     dual-headed workstation) or even <b><tt>-Z3</tt></b> (tripple-headed), and
1135     also the <b><tt>-Y2</tt></b> option for scaling down the framebuffer
1136     windows by a factor 2x2.
1137     There is also a <b><tt>-z</tt></b> option for supplying names of X11
1138     displays to use. The following example starts Ultrix on an emulated
1139     tripple-headed workstation, on three different displays (<tt>remote1:0.0</tt>,
1140     <tt>localhost:0.0</tt>, and <tt>remote2:0.0</tt>), using no scaledown:<pre>
1141 dpavlin 12 <b>gxemul -M64 -N -e 3max -jgenvmunix -d rootdisk.img \
1142 dpavlin 6 -XZ3 -z remote1:0.0 -z localhost:0.0 -z remote2:0.0</b>
1143 dpavlin 2 </pre>
1144    
1145     <p>
1146 dpavlin 6 The photo below shows a single Ultrix session running tripple-headed in
1147     GXemul on an Alpha 21164PC, with displays on a Sun Ultra1 (to the left),
1148     on the Alpha itself (in the middle), and on an HP700/RX X-terminal (8-bit
1149     color depth, running off the Alpha) to the right.
1150    
1151     <p>

1153     <a href="20041209-ultrix-tripplehead.jpg"><img src="20041209-ultrix-tripplehead_small.jpg"></a>
1154    
1155     <p>
1156 dpavlin 2 The X11 displays may differ in bit depth and endianness. Unfortunately,
1157     there is no way yet to set the scaledown factor on a per-window basis, so
1158     the scaledown factor affects all windows.
1159    
1160     <p>
1161 dpavlin 6 (If you didn't use <tt><b>-Z<i>n</i></b></tt> during the installation, and
1162     compiled your own <tt>/vmunix</tt>, then it will not contain support for
1163     multiple graphics cards. To overcome this problem, use the generic kernel,
1164     <tt><b>-j genvmunix</b></tt>, whenever you are running the emulator with a
1165     different setup than the one you used when Ultrix was installed.)
1166 dpavlin 2
1167 dpavlin 4 <p>
1168     A note for the historically interested: OSF/1 for MIPS was quite similar
1169     to Ultrix, so that is possible to run as well. If you are unsuccessful
1170     in installing Ultrix or OSF/1 directly in the emulator, you can always
1171     install it on your real machine onto a real SCSI disk, and then copy the
1172 dpavlin 6 contents of that SCSI disk into a file (using <b><tt>dd(1)</tt></b>), and use
1173 dpavlin 4 that file as a disk image file in the emulator.

1297     cause Linux to use the graphical framebuffer. Unfortunately, Linux
1298     does not seem to have a driver for the DZ11 keyboard controller yet,
1299     so you cannot interact with the system. You will see the penguin in
1300     the upper lefthand corner while booting, and nicely rendered Unicode
1301     characters, but that's about it.)
1302     <p>
1303     You need to enter some values during the installation procedure, for
