Project Petunia pages (the emulator, that will be used in AmigaOS4) updated and extended with a FAQ.

After a long period of checking forums, chatboards and answering e-mails I decided to add a FAQ part into the project page. I hope I can clean up all the important questions arising in you. If something is not clear enough feel free to write a mail.

..... when i'll can use petunia emulation on my OS4.......????

I very depressed today..... and i think that os4 is vapor.....

Relax!! Only today! I hope.... tomorrow ikir will return to be the super amiga fan....

Anyone know if OS4 even needs 68k emulation or is it 100% PPC?

AmigaOS 4.0 needs only the JIT 68k emulator, if you want to use 68k Amiga software, the OS should be 100% PPC (As far as I know) :-D

That is NOT what Ben said.....

Core parts will be PPC, but some other parts are planned for later.

That's what I understood too.  But the key parts that need the performance from the PPC chip will be native, and other parts will come in updates.

Oh no, that means the clock won't be PPC native?
We are doomed!!! :-D  :-D  :-D

At least give us a PPC calculator, that is essential,
I can't imagine what it would be running that in 68k emulation... :-D

Hi
I hope they will use "FX!32" or Transistive Dynamite approach. Using FX!32, 68K applications are converted to PowerPC through several iteration. First execution is pure emulation, but the result is stored as combo PowerPC - 68K codes. On the 2nd run, more codes are converted / optimized. In the end the software will be fully ported to PowerPC.

It might be that OS4 can have 68k (non-JIT) emulation, so that Petunia isn't immediately needed to run it. But I don't know. We'll have to see.

I guess that could be a possibility. Since Petunia won't emulate MMU's.

Hey, take a chill pill, don't fall into the crazy world of the 'unbelievers'.

For those of you who don't realise, this is a major piece of the OS4 jigsaw. After all, it doesn't require a Nuclear Physicist to work out that no 68k emulation = no applications (well alright, hardly any).

With it now ready enough to be slotted into the OS, it's another step closer for OS4 heading toward a Beta release, rather than the Alpha that it currently is.

Don't be afraid, both clock and calculator will be PPC native...  It will be blazing fast! ;-)

Everything from the recent AmigaOS will be PPC-native, only 3rd party stuff is waiting for emulation/conversion.

@Bill

L*O*L ... (they are ALL the same aren't they).

Regarding a non-JIT-68k-emu for OS4: There isn't any !!

H&P had written one once, but that won't be used (for obvious reasons).

Depending on an 100% JIT-emu can spell problems, as you always have to
compromise between fast compiling and good optimization, and need
to have a look at the JIT-cache-size /real prob on the Phase5-HW).

That's why Bernie's JIT will only start if a piece of codes has
allready been executed a few times. Using UAE's non-JIT 68k is much
faster for code that is only used once, and you don't have to throw
out other code out of a full cache.

Actually OS 4's 68K emulation concept goes beyond just a JIT.

There are benefits to be derived from a combination of both technologies.

I'm sure it wouldn't be too hard to implement. There must be 68k->PPC emulators somewhere, maybe some being open source.

If not, I'm sure they could always rip 68k emu from the public beta of MOS ;-)

You mean like they did with MUI-PPC ?  :-P

Funny, eh? I thought they have licenced the technology from mr. Stuntz, and participate also for CVS update/committing..

This thread is getting restless...

@Mr_Capehill

Sure as long as they stick to Strunzi's rules, it's o.k. , but
if you remember what Ben said about MUI at the beginning (not
needed/no part of the OS) you should understand that there
would be no MUI-PPC without R.S. porting it and then giving it
back to the CVS.
