Making it run on a very similar processor might be that quick, but rewriting most of the OS to take advantage of multiple cores would be a long task. We'd need to change the single memory-space architecture altogether.

Rouge has been given a PS3 in hopes that he might port OS4 too it, but thats about it.

Actually, I haven't. I asked DiscreetFX to take down the page and return the donations, since, as I pointed out, I cannot do what people expect me to do. I haven't heard from him, he didn't reply to my messages. I am very sorry for that, I didn't want to come across as an unthankful idiot, but I cannot do what people expect me to do with this donation, so I wanted the money returned.

Now, as I said, he hasn't replied to my messages yet. But do not get your hopes up, there will be no AmigaOS 4 for the PS 3 in the foreseeable future.

To another PowerPC architecture, yes. That includes things like the board handling, i.e. port from AmigaOne/G4 to a SAM/440 takes around a month.

Not a different CPU like PowerPC to x86.

The single memory space architecture is no problem. It's the forbid()/permit() method of gaining exclusive access to OS structures that has to go. By necessity forbid() would have to halt all other cores until permit() is called; that's just not efficient.

I read about that on an article on ars technica, where the writer said that there is already a os4 version running on ps3.

There are many things that are incorrect or half true in that article, the PS3 stuff was just wishful thinking.

I read a lot of forums, and try to remember what developers say, some stuff has been cleared up I other threads.

Some stuff I know is untrue because I develop software for AmigaOS4.0, and have the AmigaOS4.0 SDK.

The article should have been reviewed by AmigaOS4 developer before it as posted on ars technical that’s what I think.

Well I think it was meant as reword, after all you are where active in the community, answering questions and supporting every one, your not the only one that has worked hard on AmigaOS4, but you are the one that as been most public.

I think it was clear from the start you might just end up just playing PS3 games on it, and I think people are happy whit that.

I'd love something like this. Only if AOS4 run on it. I don't care if it utilized multicores right away. It would eventually.

Hi @Crumb

It's Amiga Inc's stupid license scheme the thing that is ruining the market, created solely to "milk customers".
These asses also spend their profits for law courts instead of Research & Development. You can see why Amiga is lame in development. Smart money says Genisi has better development. Believe me, you need to follow the 'smart money' these days, right?

@Rogue

I may come across as rude or ignorant since you are the key developer of OS4 but I am wondering why shelve the possibility of development for the PS3 permanently? Sony's bootloader makes the PS3's hypervisor able to detect any OS installation that can be read from a disc. There is even development for a open source graphical front-end for easily accessing specific files. Then IBM among others provide every bit of documentation and an SDK to setup a library for the SPEs.

I am not trying to argue with you since you are ultimately the currently man with the plan for OS4, it is just a suggestion. I would also like to know what other limitation there are to getting OS4 onto POWER5 based architecture or anything above ATi RV420 GPUs? Perhaps a good way to make sure, that nicely working software or even to help with future platform porting development, is a clear dialog being established with other developers? There could be a certification step involved to legally rule out any potential reverse engineers. Which I know is hard if not impossible to establish in the current situation.

But if anything I stated above reads like incoherent babble don't let it get in the way with whatever progress you are making.

Cant port os4 to ps3 but i can end playing games on it. Please send it to me :)

@Kicko

Sorry about going off topic but with Resistance 2, Little Big Planet and a few PS Eye games coming out for it nobody is going to be handing their's over to anybody. You do have a point concerning open development dialog.

I guess I'll have to accept it being ported to SAM and version 4.1 will be remain the biggest steps reported in OS4 development within at least a few years time.

Hmmm.... I smell political speak. Maybe it's the presidential election season that has gotten me all suspicious.

I can't help but notice how this thread is about this quad-core beast, and Rogue has popped up to reply to something completely off-topic like a port to PS3.

That said... he did imply a port to another PPC chip wouldn't take a lot of time.

@Rogue
We're all dying to know......
What about the a port to the subject of this thread??

Maybe we should just be thankful that you know about it.
I guess you don't want to be undermining SAM sales now don't you.

For one thing, it's not my decision to make.
Secondly, the hypervisor prohibits direct chipset or video ram access. The result is a rather sluggish behavior of Linux on the PS/3, and it is not going to get better with AmigaOS 4.x. Porting it over just to see that it is unusable is not going to work.

You overestimate my importance, really.

Quote:

There aren't any inherent limitation. The POWER5 and/or CELL are 64 bit and AmigaOS is 32 bit, but they both support the 32 bit bridge mode which poses no problem for porting. The reasons are, as I said, the limitations of the hypervisor.

@ReverseGTR
Do you own a PS3 and have tried Linux on it? I have.

Its very sluggish to use because of the hypervisor that prevents the usage of 2D/3D hardware accelerated graphics.

@Rogue


First,THANK YOU for posting ;even though you can't officially speak for your employer,what you can say has been very helpful.

So porting to another PPC is a month's work?

Excellent news!


So is the port to Mac G3/G4/G5 well underway?

If Hyperion released Amiga OS 4 for those machines,I'm sure Amigans would buy it.Even if we had to install new video cards.

I certainly would.

Especially if they did licensing like Apple so that a person could buy a 5 unit license for less than twice the price of a 1 unit install.While I dislike the idea of $150 for a single installation of ANY OS,paying $200 and putting it on 5 machines makes it very reasonable.


(currently making do with A500s,A1000s,A2000s,A3000Ds,A3000T,CDTV,SCALA box(CD32 w/SX-1),CD32s),all which are past their "best used by "date!)
And a bushel of Apples plus IBM clones.Bought 2 Amiga Forever CDs for the IBMs.

Running DOS 2.11 to XP Pro,OS2 Warp,MacOs 7.5 to 10.4.11,Ubuntu,Slax,and Fedora.

You can read about Moana in #9:

Official Amigaworld.net list of potential hardware candidates for OS4

As has been stated previously, currently the only hardware available for purchase is SAM440ep.

You can read a current Q&A with Acube Systems, which mentions future plans:
