Even with low-power CPU (laptop) it could deliver G3 1 GHz class performance (eg. like A1-500), support for 3D GFX is nice bonus.

For some people, never. Emulation simply is not "the real thing".

for me as amiga user names like sam, amigaone, pegasos or whatever are completely meaningless. for me morphos, os4 or aros might run on whatever hardware it wouldnt make any difference.

Well, I clearly see Amiga in AmigaOne name.

@pavlor
Than don't call it emulation : )
I have a mini loader ready which theoretically could fit as payload into a BIOS Rom.
That way you would think that there is no emulation involved.

Make a mainboard with integrated catweazel and you are done.
Of course as soon a user would try native aros he would not go back to os4 : p (kidding)

@pavlor

and where is amiga in "sam" or "pegasos" ? or do you want to imply that those running os4 on those machines belong to some other inferior class of people?

Did you read our discussion with phoenixkonsole? My point was: Although lower-end OS4 market would be affected by possible PowerPC emulation, there are still people willing to pay for dedicated Amiga branded computers.

I might be completely wrong so don't be mad if I am, it's just a feeling. What I'm thinking is that maybe they've contacted him and wanted this since he said that it would never happen but suddenly changed his mind? It would make sense because AOS isn't gaining new people. Just a thought. If it's good or bad I don't know but "I got a bad feeling about this".

Well, let's see. UAE PPC with AmigaOS 4.x could allow:

1) ECS and AGA Amiga chipset compatibility
2) fast Windows and Macintosh compatibility
3) laptops for AmigaOS 4.x
4) cheaper low end AmigaOS 4.x computers
5) Macintosh PPC computers to use UAE+real PPC
6) Wii, PS3 and XBoX to use UAE+real PPC
7) virtualization capabilities with multiple operating systems
8) multiple cores/threads to be used
9) more memory to be used
10) more hardware options

Toni has opened up all these opportunities for AmigaOS 4.x. Tight fisted and controlling Hyperion has nothing to worry about .

JIT emulation can play all sorts of tricks on performance benchmarks, so I'd be very wary of drawing such conclusions.

I doubt it. I think majority of OS4 users are using SAM or Pegasos 2. A1-500 is very rare and by numbers AmigaOne users are minority. And the brand name loyalty has its limits. If there are users who ditch OS4 there are users who ditch dedicated AmigaOne hardware. It is the OS an the AmigaOS name that matters anyway. Everything else is just small extra.

But it depends on how fast WinUAE can execute PPC code if ever. We dont know yet.

But that is what I wrote in my post 10:

If emulated CPU is fast enough (and it seems PearPC core is), it would certainly destroy low-end OS4 hardware market.

Exactly.

Even if the WinUAE PPC emulator can't execute code fast enough on non-PPC processors, cheaper existing PPC computers (PPC Macs and consoles) can be made to use the existing PPC processor at full speed or nearly full speed. Who is going to pay $1000 for a SAM when they can buy a G4 Macintosh for $100? Plus the AmigaOS 4.x classic version is cheaper (and just went up in value). Plus UAE can seamlessly emulate the ECS+AGA Amiga chipset and WarpOS. Also, a UAE+AmigaOS 4.x+ G5 Mac could potentially outperform an Amiga X1000 for a fraction of the price. It is not just the low end OS4 market that is threatened, but the whole OS4 market and Hyperion marketing model.

How?

There is no such solution. Toni just want to add PowerPC emulation to WinUAE, not to port OS4 to PowerPC Mac. I repeat, it is PowerPC on x86 emulation, not some kind of virtualisation on PowerPC (like ShapeShifter on 68k, or SheepShaver on PowerPC was).

Quote:

Not yet.

@Pavlor

"Not yet" how you wrote

WinUAE is base for most other UAE emulations like FS-UAE and others. So "changes" he is doing now will certainly be ported. Matthey should have wrote "potential threat for...".

@OlafS25

Quote:

Sure, but not in sense of some clever virtualisation on PowerPC based Macs (although that wouldn´t be bad).

Is there any such open-source CPU virtualisation solution for PowerPC? As for emulators: PearPC (as tried by Toni now) supports only x86, Dolphin x86 and ARM. QEMU has support for many host CPU architectures, but not in sense of virtualisation in case of PowerPC.

Note: OS4 needs also PowerPC MMU. If desired emulation solution doesn´t support this, OS4 will not run.

@pavlor

if you google both PearPC + MMU you get hits so I would say yes. It was developed to emulate Apple PPC hardware on X86 and I do not think that Mac OS worked without MMU

I kinda always thought he had to do it at some point as really he was running out of things that need to be emulated on UAE. Best of luck with the project.

Yes, that is what I say - PPC hardware emulation on x86, NOT PowerPC virtualisation on PowerPC. I fear my English language skills are weak.

@pavlor

I think that the full PearPC package is a kind of emulation of the Apple PC hardware like some of the amiga emulators emulating a complete PC. Toni takes the CPU part from it (not the full package).

Exactly. matthey´s point was to use such impoved UAE on PowerPC Macs to run OS4 - nonesense in case of PearPC CPU core.

Making PPC code execute near full speed on a real PPC processor is simpler than coding a PPC emulator. Some PPC processors would need patching while others would need practically no changes.

Not yet but the necessary coding is not rocket science and the UAE sources are freely available. Most of the needed code may already be available from other open source projects. Is the code for SheepShaver open source?
