NetBSD 6.1.5 Sparc64 on Qemu

Yes, really!

I thought I’d try it for the heck of it, and it’s working enough to go multiuser, but it has some issues with hitting the disk & network pretty hard.  But it does let you install!

I just started it up like this:

qemu-system-sparc64.exe -cdrom NetBSD-6.1.5-sparc64.iso -net nic,model=ne2k_pci -net user -boot c -hda netbsd-615-sparc64.raw -nographic -serial mon:telnet:127.0.0.1:23,server,wait -m 2048 -boot d

And in no time I was booting up!

Wow, how’s that for cool?

A few notes though, if you use a VMDK disk access is dreadfully slow during the install, raw disk images are MUCH MUCH faster (36Kb/sec vs 3+MB/sec).  The kernel cannot figure out the root disk, so you have to tell it on every boot.  When installing it’s cd0c, when booting off the harddisk it’s wd0a. The e1000 adapter causes the kernel to go crazy, and on bootup the system indexes the man pages, which seems to kill the machine.

makemandb
makemandb indexing like crazy

As you can see this is what happens when you hit the disk too hard..

# dd if=/dev/wd0c of=/dev/null bs=1m
^Ccmdide0:0:0: lost interrupt

463+0 records in
463+0 records out
485490688 bytes transferred in 59.701 secs (8132036 bytes/sec)

and if you don’t incur the rage of the disk controller it’s the same speed:

# dd if=/dev/wd0c of=/dev/null bs=1m count=10
10+0 records in
10+0 records out
10485760 bytes transferred in 1.217 secs (8616072 bytes/sec)

But yeah, I can’t complain!

 

OpenWatcom v2

I know what you are thinking, wouldn’t it be great if you could create MS-DOS executables directly from a Win64 desktop with no MS-DOS needed?

Well, I just found out about this unofficial Open Watcom v2 project that targets the usual suspects, allows you to compile from Win64!

Hello World!
Hello World!

Some of the features of this fork include:

  • New 2-phase build system, OW can be build by platform native C/C++ compiler or by itself
  • Code generator properly initialize pointers by DLL symbol addresses
  • DOS version of tools now support long file names (LFN) if appropriate LFN driver is loaded by DOS
  • OW is ported to 64-bit hosts (WIN64, Linux X64)
  • Librarian support X64 CPU object modules and libraries
  • RDOS 32-bit C run-time compact memory model libraries are fixed
  • Resource compiler and Resource editors support WIN64 executables
  • OW text editor is now self containing, it can be used as standalone tool without any requirements for any additional files or configuration
  • Broken C++ compiler pre-compiled header template support is fixed
  • Many C++ compiler crashes are fixed
  • Debugger has no length limit for any used environment variable

Binaries are available on sourceforge.

So how does it fare?  I thought I’d take the old Wolf4GW, and compile it with this toolset.  The first hurdle I hit was this fun feature:

  • The C++ compiler now treats warning W737, implicit conversion of pointers to integral types of same size, as an error.

Which is an integral part of wl_menu.cpp .  So this was somewhat problematic, until I just commented out that block, and while I was expecting no working keyboard, I’m able to play, and load/save games…. Even the boss key works.

Wolf4GW
Wolf4GW

So with the W737 taken care of, I have to say this thing compiles FAST.  Incredibly FAST.  If for some reason you have to build 16bit or 32bit anything, you should look at a 64bit tool chain, well assuming you have a 64bit computer by now.

If anyone want’s to build their own Wolf4GW with the newer OpenWatcom, my source drop is here.

64bit Windows QEMU builds

I stumbled across this page, which has installers & executables for Win64 based OS’es of Qemu!

Of course this is very exciting… considering I never could get a working build of Qemu for a Win64 platform, and more or less gave up.

From the brief guide on building, it looks like they use POSIX threading and cross build from Linux.  Naturally I’ve been trying to use native tools & Win32 threading as I saw mentioned over here.

Maybe one day I’ll be able to get it working in a semi-consistent manner and put back in my lame fixes disabling screen resizing in a window, and control alt delete shortcuts.

Windows 8 x64 and Qemu

Since people have been asking, does it work with Qemu 1.0.1?  And the answer, sadly is ….

 

sadly…

no.

As you can see the primary error code is 0x000000c4

0x0000000000000091

0x000000000000000f

0xfffff802cc92e880

0x0000000000000000

And that is about it…..  And of course keeping in mind that Qemu hasn’t been able to boot a 64bit version of Windows since 0.9.0 and Windows XP x64/Windows 2003.

Running Qemu as a Windows service …

Long story short I’m doing some work with a network that suffers a lot of ‘you can’t get there from here’.  They’ve given me VPN access and yet even the VPN cannot get to a lot of stuff.

The solution for them is to use this old server and ssh out from there to the rest of everything.  Which for the most part works fine, but if more then 2 people need to leapfrog suddenly you are waiting in line, or constantly knocking people off.

So I figured I’d do something different, install a QEMU virtual machine on the server during my allotted hour, and then launch it as a service so that I could leap in/out through the VM leaving the console free.

While I am going to add Qemu as a service, it is still somewhat stealthy as I don’t need device drivers, and I can run it nested as I know this machine is slated to be migrated to VMWare ESX.  And the best part of that is that it’ll continue to run.

So how do we set this kind of thing up?

The first thing you’ll need is srvany.exe instsrv.exe which both can be found in the Windows 2003 resource kit.

Installation is very straightforward, just remember to use complete paths for your Qemu, BIOS, and disk files.  Installation goes like this from the command line:

InstSrv qemu c:\qemu-0.15.0\srvany.exe

This will create a service entry named Qemu, which will in turn kick off the srvany executable from the resource kit.  Now I know what you are thinking, what about Qemu?  Well we have to specify that using regedit.  Also remember that because you are going to run this as a service you don’t want the SDL display popping up and scaring some poor hapless user.  So the first thing I’d recommend is to work out the flags that you want to start with.  Something like this:

c:\qemu-0.15.0\qemu -L c:\qemu-0.15.0\qemu\pc-bios -hda mydisk -net nic -net user -redir tcp:2222::22 -vnc w.x.y.z:2223

This will redirect tcp port 2222 into the VM for ssh, and sits the VNC display on port 2223 …

So we fire up regedit and navagate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Qemu

There we add a new key “Parameters”.  Then add an ASCII key of “Application” then just paste in the all of the qemu flags as mentioned above (or changed as needed by you).

Then you can simply start/stop the thing using the net start/net stop.

I suppose this is a little subversive (lol) but sometimes you’ve got work to do and the best way through it to piggyback on someone else’s computer.  Also I really fail to see the ‘wisdom’ in creating ACLs that only permit you to access your routers/switches from your desktop when you could easily *NOT* be in the office.  Or this guy just likes the excuse of not being able to work from home.

Anyways not to ramble but that’s how I ‘fixed’ the issue without ruffling too many feathers.

Windows 2008 & Proxmox VE

Just a quick tip to people running Windows 2008 under Proxmox/VE (I know this applies to the amd64 x86_64 version probably i386 as well) sometimes when you reboot it’ll come up and crash saying that there is no available hard disks. Then it’ll go into recovery mode and … somehow claim you have no hard disks.

Turn the VM OFF.

Wait a few seconds.

Turn the VM ON.

I had this issue after installing antivirus software in the VM, but I guess there is other things that may set it off. Anyways after a shutdown, power cycle of the VM it’ll boot back up.

That’s it!

I’ve got to stop watching the blogger stats…

Because then I see something like this come my way as a query from google:

“is there a version of colossal cave adventure that runs on 64 bit systems”

Well I certainly can’t let that one go unanswered.

So whomever you are stranger, here it is. Well for Win64 x86_64 machines.

This is built using f2c on MinGW64. I’ll spare you the details, but it compiled, and fired up and I got lost in the woods… So I assume it is working…..

For those of you not in the know, colossal cave adventure, or sometimes known simply as ‘adventure’ is the grand daddy of all text adventure games.

As mentioned in this timeline of adventure versions, adventure was written by Willie Crowther and expanded by Don Woods. This version, the Kenneth Plotkin version was derived from Kevin Black’s DOS version and Bob Supnik’s Decus versions.

With that said, there is a tonne of INT2 and INT4 casting, which I’ve just removed as I’m passing it through f2c. I suppose I could have seen about fixing the variables, but I just fixed the ones f2c and gcc really complained about. Included in the download is the modified source, and the original source, so anyone can take a look at it.

Naturally Wikipedia has a most excellent article on the history of adventure, check it out.

Colossal Cave in 64bits!

MinGW-w64

Well after yesterdays x86_64 excitement, I figured I’d take a look in the windows area to see about the 32bit vs 64bit performance on Windows…

I know this isn’t the ‘best’ test as I’m using VMWare Fusion on OS X and running Windows XP x64 sp2 (the 2007 edition, not the 2003 one).

If anyone wants to know how to get a 64bit gcc on windows, this is the best formula I’ve come up with so far.

First download a build of mingw-w64-bin_x86_64 from sourceforge… Right now I’m using a ‘Personal Build’ from sezero_20101003, because… it’s recent, and I would imagine a personal build has some hope of actually working.

I downloaded that, and extracted to the root of the C drive. Then I renamed the mingw64 to mingw.

Next up, I downloaded and installed MSYS 1.0.11, and installed that. I selected the default options, and of course specified my mingw is installed in

C:/mingw

After that, I install the MSYS DTK 1.0, again with default options.

The final part is some kind of editor, I like VIM but it’s… involved to download as the default package ‘vim-7.2-1-msys-1.0.11-bin.tar.lzma’ is in a 7zip compatible archive that needs a bit of tweaking to get a tar file out of. I can provide it here in gzip format, that you can simply extract within the msys command prompt in the /usr directory.

Now with all that done, you should be in business!

$ gcc -v
Using built-in specs.
Target: x86_64-w64-mingw32
Configured with: ../gcc44-svn/configure –host=x86_64-w64-mingw32 –target=x86_6
4-w64-mingw32 –disable-multilib –enable-checking=release –prefix=/mingw64 –w
ith-sysroot=/mingw64 –enable-languages=c,c++,fortran,objc,obj-c++ –enable-libg
omp –with-gmp=/mingw64 –with-mpfr=/mingw64 –disable-nls –disable-win32-regis
try
Thread model: win32
gcc version 4.4.5 20101001 (release) [svn/rev.164871 – mingw-w64/oz] (GCC)

 

But will it run Dungeon?

What is also cool, is that this build of mingw includes gfortran, which is a Fortran 95 compiler with various 2003 & 2008 enhancements. So for the heck of it, I’ve rebuilt the makefile from dungeon-2.5.6 and tweaked the machdep.f to at least call the ITIME function to get the current time. The resulting archive runs pretty well!

Windows XP x64 - dungeon

Yes, it runs! And without a *32 meaning this is a 64bit binary!

 

Onward with SIMH

So going back to SIMH as my benchmark, here is the vax780 with -O0/-O0

Dhrystone(1.1) time for 500000 passes = 18
This machine benchmarks at 27777 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 20
This machine benchmarks at 25000 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 19
This machine benchmarks at 26315 dhrystones/second

Which comparing it to the native x86_64 build is pretty good considering I’m running this in a VM (VMware Fusion!). Now the same test with -O1/-O1

Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second

Which is pretty good! Now for the finally with -O2/-O1

Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second
Dhrystone(1.1) time for 500000 passes = 12
This machine benchmarks at 41666 dhrystones/second

Which is interesting in that there is no appreciable difference in the -O2/-O1 vs the -O1/-O1 build. Although I kind of expect different results on a native machine. If anyone else cares to test, I’m going to make available the whole project here. This includes the source and the pre-built binaries.

Unzip it on a win64/win32 machine and it should be somewhat straightforward to build / run. You can alter the makefile and change the primary CC flags from O0 to O1 or O2 if you so wish… just run make and it’ll generate a vax780.exe . Then in the test directory you can bench your exe like this:

The d0,d1,d2 are the dhyrstone benchmark compiled with -O0, -O1, and -O2 respectively. This gives you a chance to observe various optimizations in the GCC 2.7.2.2 for the VAX.

Neko x64!

 

For no real reason today I remmeber that there used to be this cool program back in the Windows 3.0 days called Neko. I was trying to explain it to my girlfriend about this cat that would chase your mouse!  Click the picture above to play with neko in jdosbox.

I recal that Neko even made it to OS/2 as it was more interesting then the mouse trails alternative from Microsoft.

 

At any rate, I was wondering if there ever was a 32bit version of Neko… And much to my amazement I found there was a Neko95, and a Neko98! And they even ran on my x64 version of Windows… So after googling around, I found the source code to Neko 98!

So I did the next best thing, which is download the source, fix a single casting ‘error’ in some square root function and I got it building under Visual C++ 2008. Then I figured, what the hell, added a target for the x64, and built… a 64 bit version of neko!

 

You can download the x64 binaries, and the source directory that I used here.

You may need some VC runtimes if your system is an old x64… At this moment it can be found here:

Or by searching for Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)

Oh well at any rate, it’s cool to see Neko still kicking!

PS When I get back I’ll have to see about an i386MIPS, Dec Alpha and Itanium build… wink wink!

—edit

Neko98’s source code has been rescued, all saved here.

—years later

I just received this screen shot of Neko x64 rocking it on Windows 8 (Desktop mode)
