Blood for WarpOS!

 Thanks to BSzili (on EAB) Blood from Monolith (in the form of nBlood) is now available to Amiga! Cowcat and I have taken up the task to port this to WarpOS. Below can you see a work-in-progress. Sorry for the bad quality. If it is finished probably somebody else will do a much better job :-)

It is running on my AA3000+ with a Mediator (I replaced the FireBird for development a bit) and a Radeon 9200 Pro card with a Apocalypse card (MPC7410 / 256MB).

The current showstopper for release is multiplayer. It works, but it slows down the game a lot (from the fps you see in this video to below 20 fps).

MIDI slows down a bit in heavy scenes and also window mode is sluggish, but those I don't consider real show-stoppers.

As you can see, FPS is not too shabby. This is on 640x480 with interpolation on and details on highest:

Playing with my new toys!

Bought myself some covid-comfort gifts a few months ago. First off the amazing AA3000+ made by Hese. It is a hybrid of two prototype Amigas. The AA3000 and the A3000+ meaning it has AGA and a DSP. For more info on the latter I point you to A1K.org.

Secondly, as I was toying with CAMD in the latest ScummVM sources (back then 2.2) and I needed something to actually test it (and was sold by some of the ScummVM plus MIDI movies on the internet). So I bought myself a Roland SC-55 MKII all the way from Japan. Finding a correct power supply took longer than expected, but the result is cool IMHO.

Further specs of this AA3000+ is a CSMK2 running on 55MHz, a Ragnarok PPC card running on 800MHz and some card that cannot be named with 128MB gfx RAM.

Shown are "Day of the Tentacle" and "I Have No Mouth, and I Must Scream".

New Amiga driver for PCI network card....

Well, sort of. We are talking about the BigFoot Killer NIC here with a dedicated NPU for helping out with the network traffic to reduce latency and ping. It was advertised as giving you an edge to kill virtual people faster.

So why for the Amiga then? Well, the Network Processing Unit, or short NPU, is actually an MPC8343E PowerPC CPU running at 400MHz. The card also had 64MB DDR RAM on-board.

Here's a picture of the card with mega-awesomeness-superduper heat sink:

That NPU can be used to run WarpOS software when plugged into the Mediator:

This is a cheap alternative to the more expensive PPC accelerator cards. It only has 64MB on-board so don't expect running Quake III on it. Currently people are looking whether or not the on-board RAM can be upgraded by the means of modding.

Have fun!

Developing for WarpOS

Of course it is fun to play with the old stuff on the Sonnet and the Rapture card. But how about new stuff?

The old GCC compiler for WarpOS (2.95.3) was hopelessly outdated and VBCC doesn't support C++ and most of the C sources out there need some adaptation to compile on VBCC.

Enter another project of mine: mos2wos. This stands for MorphOS to WarpOS and is a set of tools to develop for WarpOS on MorphOS machines. Now you can use the newer GCC binutils from MorphOS and what is even better, you can use GCC compilers version 4.4.5, 5.5.0 or 6.4.0 to produce WarpOS executables!

It took a few months to mature, but it is getting to a point that it is getting usable with a freshly compiled SDL library especially made for WarpOS and a very up-to-date C library (newlib 3.0) making porting even more easy!

How useful is it? Here are some examples compiled with version 0.8:

Power in Diversity

A while back, well actually June 2015 or around there, I should a picture of a PMC2PCI card. Since then I have been scouring the Internet for suitable PMC cards. Tried a bunch of them, but none of them worked.

Then I got some help from an expert in PMC cards and he delivered :-)

Below is a Force PowerPMC-250 card with a 450 MHz MPC7410 (G4) card with 256MB SDRAM on-board:

With a PMC to PCI carrier card it was added to my A3000UX and here is the first result after updating the driver:

The card is regarding power consumption on the edge of what the A3000D can handle. The Amiga has to warm up for a couple of minutes before the PPC card becomes stable. It is not the PPC which is crashing, but the 68K when fetching/running code from the PPC memory. But as said, after a while it becomes stable. I guess I need to upgrade my PSU.

I also wish to thank Elbox for their speedy support in updating their pci.library to support these kind of cards!

Hopefully, we can ramp up with faster cards in the near future.

Quake 3 on the Sonnet

Lately, there has been a resurgence of porting of games to WarpOS and Quake 3 is one of them. This port was done by CowCat. Still in alpha, but it definitely has potential.

Sadly, this phone has a worse camera than my previous one. Also, playing with the keyboard which was behind the camera was a tad difficult, hence the weird walking sometimes :-)

Dabbling with Warp3D..

Just a teaser. I've been converting some OS4 and/or 68K Warp3D stuff to OS3 and PPC. Here some first results.

I haden't posted in a while....so... :-)

Hope to show you some more the coming weeks. Or not... who knows...

Further developments...

Now with sound :-)

Some glitches here and there and a annoying mouse pointer in the way, but it's getting there. I also notice I need to silence my A3000UX PSU one of these days.

Some developments....

There has been a little movement on the WarpOS front as of late. Cowcat, who did a great job the last few years on Quake2 and BlitzQuake now tried his hands on Hexen II.

Here is the result:

Sound needs an overhaul and I guess I need a better camera, but for a first beta is it really cool. Well done!

SIMD for classic Amigas

As you all of course know by now, Sonnet cards are rather hard to be found. Even more rare is to find a Sonnet Crescendo 7200 G4. There were a few for sale when I started this project over 2 years ago, but they wouldn't ship to Europe. Since then, it has dried up, even for the G3s, on the various market sites.

A good friend of mine happened to have bought one....maybe 6 months ago. He lives in Germany. While I was in the neighborhood I could setup and test the G4 card. The computer used was a busted up A3000 with a Mediator and a Voodoo3. Also in the picture you can see a CSPPC:

The CSPPC makes it impossible to close the A3000, as the cooler of the 060 was too high. So we set up the system in a very unconventional way :-) It was running a bare OS3.1. 

As the biggest difference between G3 and G4 is AltiVec (I'm not certain about number of pipelines and FPU speed) which is a so called SIMD instruction set which speeds up certain calculations, the first program run was the dnetc program. It supports AltiVec, or so I thought:

As you can see in the above picture, no speedup or AltiVec cores chosen. This was due to two issues. One, the sonnet.library needs to activate the AltiVec stuff when available. And two, dnetc for WarpOS does not have AltiVec compiled in it. So after a bit of work I added AltiVec support to sonnet.library:

Here you can see my system with the G4 card. GetInfo recognizes the card correctly. In the window on the left you see part of the AltiVec support in sonnet.library. It's the loading of the various AltiVec registers after a task switch (when AltiVec is detected (PSL_VEC)).

As AltiVec programs for the classic Amiga are even more rare (WarpOS does not support it and there are 0 (zero) programs which use it), I wrote a small program to test if it works and that seems ok.

Next step would maybe be to port some MPEG-1 player. Or maybe you guys have some AltiVec sources lying around I could test? Much appreciated :-)

Lies, damned lies and statistics

Added functionality to the sonnet.library which tracks CPU usage (time running), busy time (time not waiting) and activity (time.... I forgot, but the tooltips of WarpStat are very handy :-)

I also noticed that people are having a hard time to install the Sonnet card. (The few people having one). I actually got a copy from a Workbench of someone and my Sonnet refuses to work with that system disk. Not sure what the problem is yet... Seems like the set P96 screen modes are messing with the system. Have to look further into it.

Next post will be probably about all the pitfalls of installation :-)

Blue in the face!

As said in the previous post, the last update made it possible for more demos to run. Here's one from that OTHER ppc solution back in the days: PowerUP from Phase 5.

The demo called Glare is from the widely known PPC demo group Mad Wizards. The video doesn't handle lighting perfectly (some of it is overexposed for example), but it is the thought that counts :-)

Enjoy!

Buggy first try at PPC assembly....

While doing the ReWarp project and testing out all kinds of demos (the hardest things to get going IMHO, they break system conformity quiet often), I decided to test some of the demos also with the sonnet.library. A hard crash with the first demo (bus error) and a DSI error with the other was the result

After debugging I found some serious bugs in the oldest code of the sonnet.library. The very first functions implemented were GetInfo, Alloc/FreeVecPPC and the TagItem functions (NextTagItemPPC etc.). I hadn't looked at this part of the code in almost 1.5 years. It were my first real tries at PPC assembly.

Anyway, that fixed the bus error problem.

The DSI resulted from the demos allocating memory for the PPC using Run68K and not the native PPC memory allocating functions. After a fix to that I had some fun watching demos:

MadWizards - Till I Feel You:

MadWizards - Third Eye Conqueror:

Some gfx bugs in some scenes, but overall it looked good! I hope to publish a video soon!

Increased compatibility

With the introduction of the latest features in the sonnet.library: Correctly working mirror tasks and a shared signal system between the two CPUs, the compatibility with WarpOS has increased. Also some speed was gained (5-10%).

The major result is that in FreeSpace there now is sound. Also the timing task and the sound output task within ScummVM WOS are now correctly working.

Here are some movies with build 140 in action:

Samurai Showdown 4 for the Neo Geo (NeoMAME): I noticed later that the health bar is missing. This is an artifact of the chosen FrameSkip parameter (2):

Here ScummVM for WarpOS version 0.7.1. (no newer version, sadly enough): The heavy hick-up in the beginning is encoding related. It is however not running at full speed due to extra context switches due to CHIP memory access attempts by the PPC.

Finally FreeSpace: The Great War: I had to turn of music streaming due to artifacts in the sound output. It is not always there when I start the game. Need to investigate that one further. I cut out parts of loading screens to shorten the movie a bit.

Until next time!

PPC Demos on the Sonnet

I was looking to get some demos running on the sonnet and a posting on EAB came in very handy (see it here: http://eab.abime.net/showthread.php?t=71650). It listed some demos which are suppose to work on CSPPC/Voodoo3. So I picked the very top one and did a small & quick patch to the hunk header and names and here is the result:

Compare this to a CSPPC on 366MHz and G-Rex/Voodoo3 (Pardon the shaking, it is not mine ;-))

I know it is a bit difficult to read so here are the FPS:

x - CSPPC 366 MHz - Sonnet 500 MHz
1 -             33              -              46
2 -             22              -              32
3 -             20              -              38
4 -             18              -              30
5 -             21              -              30
6 -             17              -              29
7 -             48              -              50
8 -             18              -              31
9 -             22              -              42

Picture of the Day: Unlimited Powerrrrrr

While I'm debugging the code and chasing some nasty bugs, here's the sonnet card doing a PowerUP program using ppclibemu from Frank Wille. Yes, it is an ELF binary.

Picture of the Day: Sonnet Developments

Not a flashy video showing 3D madness, but a picture showing the Sonnet compiling vasm, the assembler used to compile the sonnet.library. In this instance, the resulting binary runs on the Sonnet and puts out PPC code usable by the Sonnet.

3D In Motion!

I had some time off between cooking for the family x-mas dinner and had a look at Warp3D. I had looked at it before and back then it just crashed the system.

This time around I noticed that the ramlib_ppc task was the culprit. So I googled around and found that it was a common problem within WarpOS/Warp3D. The stack is just too small.

So I upped the stack size for ramlib_ppc and installed a 68k patch for ramlib itself and now the sonnet library hanged on a DSI when opening Warp3DPPC.library. Debugging showed that this was because Warp3DPPC.library was loaded into FAST memory. Memory the PPC on the sonnet card cannot reach.

So the InitSonnet program was adjusted to pre-load all the Warp3D libraries to the memory of the Sonnet and below is the result (e.g. 75 FPS on the Warp3D gears program).

On a side note: I had ordered multiple Sonnet cards from the US for $25 USD dollar a piece on http://resale.headgap.com/. Too bad they now removed it from their web shop without replying to me. I guess they didn't had it in stock anyway...

Happy New Year :-)

Happy Holidays!

Happy Holidays from the SonnetAmiga Team!

As the year closes it's time to show a clip about the current state of the library. ;-)

The fade in the sound is the monitor switching resolutions (it's a monitor with build-in speakers). As people might remember, this is 2 out of 3 of my personal goals done.

See you all in the next year! The new year resolutions are

*) Warp3D support
*) WarpDT support (Goal 3)
*) A4000D non black mediator mod
*) A4000D black mediator support
*) A1200 TX/SX support.

Hopefully Santa has some secret stash of Sonnets somewhere.... ;-)

MooOOoo!

One of the early goals of the project was to get some specific stuff running on the G3 processor. The WarpDT suite, the MP3 engine for AmigaAMP and the dnetc client (see distributed.net).

It took me the better parts of a week to finally get some results regarding the dnetc client. Of course it is a good thing that for every program I try to run I need to do a lot of bug fixing in the sonnet library, but it can be tiresome sometime :-) On the other hand it gives me more and more insight on the inner workings of WarpOS. Anyway here the first output of the client:

As you can see, the speed is as what is to be expected from a 500 MHz MPC750 processor. It still crashes on exit, but I guess that's for the next week :-)

And yes, I have not forgotten to look at the A1200, but I first want to have this 100% running.
