[Forum] Any NEW amigaONE Linux Kernel? ANN.lu Posted on 11-Aug-2004 09:26 GMT by SpawnPPC 55 comments View flat View list Any news about a new AmigaONE Linux Kernel, with DMA and 3D support for ATI RADEON cards? Any NEW amigaONE Linux Kernel? : Comment 1 of 55 ANN.lu Posted by JoannaK on 11-Aug-2004 08:48 GMT Seriously.. Who cares anymore? Those who purchased AmigaOnes did so because of upcomin OS4 and they have got it (actually some feature lacking beta variant of it but...). For others, that machine has nothing to offer. It's way too pricey, too flakey etc to be used as a Linux machine. Any NEW amigaONE Linux Kernel? : Comment 2 of 55 ANN.lu Posted by Thomas Würgler/Pagan on 11-Aug-2004 09:02 GMT I guess we can safely say that at the moment Linux development is not a priority on the A1. I do think though that once development of OS4 nears completion (or whenever someone gets some spare time) we will see some updates for Linux. It is nice to have a backup OS to boot into, if you need to do home banking or similar, which isn't possible on AmigaOS till we have java and an advanced browser (in most cases - I do know some just require SSL). Any NEW amigaONE Linux Kernel? : Comment 3 of 55 ANN.lu Posted by Don Cox on 11-Aug-2004 09:11 GMT In reply to Comment 2 (Thomas Würgler/Pagan): "I guess we can safely say that at the moment Linux development is not a priority on the A1. I do think though that once development of OS4 nears completion (or whenever someone gets some spare time) we will see some updates for Linux." My guess is that nothing will happen until the next generation of MAI's chips is available. MAI are the people who might benefit from having other OSes running on their hardware designs. I can't see why Hyperion or Eyetech would devote any time to it - they have both always wanted a new Amiga. Any NEW amigaONE Linux Kernel? : Comment 4 of 55 ANN.lu Posted by ikir on 11-Aug-2004 09:27 GMT Spawn you should visiti my website more! On MAI ftp there is a 2.6 testing kernel. Any NEW amigaONE Linux Kernel? : Comment 5 of 55 ANN.lu Posted by koan on 11-Aug-2004 11:05 GMT In reply to Comment 3 (Don Cox): I can't see why Hyperion or Eyetech would devote any time to it - they have both always wanted a new Amiga. That may be true but IIRC Eyetech thought AmigaOne was a good thing for Linux because PPC based machines didn't need so bulky fans, if any. They were saying that A1s would be highly desirable for servers as you could fit more boxes per rack and they would recoup a lot of money through this application alone. Personally, I want an Amiga I can run Linux on from time to time. koan Any NEW amigaONE Linux Kernel? : Comment 6 of 55 ANN.lu Posted by Bernie Meyer on 11-Aug-2004 11:45 GMT In reply to Comment 3 (Don Cox): I guess Hyperion might be interested --- because on December 4th, 2002, no other than Ben Hermans wrote "I can assure you that Hyperion & Co were indeed contracted by Mai and Eyetech to have Linux PPC SuSe running on the Teron CX/PX/A1. This development is being spear-headed by Hans-Joerg Frieden of Hyperion in conjunction with several other valuable developers with A1 machines".It's all there in the "Eyetech reply to BBRV open post" thread. Truly an interesting read 20 months later. Highly recommended :) Any NEW amigaONE Linux Kernel? : Comment 7 of 55 ANN.lu Posted by Bernie Meyer on 11-Aug-2004 11:55 GMT In reply to Comment 6 (Bernie Meyer): In the same thread, Ben says "We were contracted by MAI to adapt the current state of Linux PPC to the Teron CX/PX/A1 hardware".Quite unambiguous, and quite in contrast to the more recent position of "Why should we care if Linux' DMA drivers corrupt data on the A1, we do OS4, not linux" (paraphrased, obviously). Any NEW amigaONE Linux Kernel? : Comment 8 of 55 ANN.lu Posted by Don Cox on 11-Aug-2004 12:57 GMT In reply to Comment 7 (Bernie Meyer): I must admit I'd forgotten some of that. However, it makes it even more likely that they are waiting for the new Northbridge chips. Any NEW amigaONE Linux Kernel? : Comment 9 of 55 ANN.lu Posted by Thomas Würgler/Pagan on 11-Aug-2004 12:59 GMT In reply to Comment 7 (Bernie Meyer): @Bernie: Well, obviously disabling DMA under Linux is the recommended thing to do at the moment - unless you don't mind reinstalling. Linux development hasn't stopped. It's just not top priority - which I think is perfectly understandable at this point in time. Btw... still working on your project? :) Any NEW amigaONE Linux Kernel? : Comment 10 of 55 ANN.lu Posted by Olegil on 11-Aug-2004 13:18 GMT In reply to Comment 7 (Bernie Meyer): Well, if my memory serves me the reason why Hyperion did the initial port of Linux was as a proof of concept because they did the porting of PPCBoot. After it was shown that the parts involved in booting worked fine their commitment to Linux on the A1 ended and other people were invited in. Very few took up that invitation and did anything constructive. MAI and Eyetech should have donated some hardware to professional kernel developers instead of thinking they would get them for free. Because you don't. Linux is developed by professionals for money and by hobbyists for fun. Doing it the other way around is a certain disaster :-P Any NEW amigaONE Linux Kernel? : Comment 11 of 55 ANN.lu Posted by NoBeForMe on 11-Aug-2004 14:21 GMT In reply to Comment 7 (Bernie Meyer): No need to paraphrase, here's a direct quote from a Hyperion employee "we won't waste our time fixing the Linux Driver" Just in case anyone isn't yet familiar with the history in this area.... During Autumn 2002 rumours circulated of problems with the Teron/A1 hardware, and also with the Pegasos, being built on the same Articia S Northbridge. These claims were dismissed by Eyetech and Hyperion who had conducted extensive tests and completely validated the A1 hardware. In early December 2002 the story was now that the Teron/A1 used a buggy VIA southbridge and the OS4 IDE DMA driver included a suitable workaround for the problem, as did the Linux drivers. There were no problems with the Articia S, and Eyetech had done extensive tests to prove that. A week or two later, just after Christmas the new story was that early Articia S chips were buggy, and Eyetech knew that it could be fixed in software, but instead they had a hardware fix to tide them over until MAI shipped the next, fixed revision. Then Eyetech announced that AmigaOne Earlybird hardware would definitely include the hardware fix from MAI, incorporated into the Articia S itself. The problem had been completely eliminated. Reports of problems continued regardless. In August 2003 the VIA southbridge story was back. A patch to U-Boot and to the Linux Kernel was developed by Hyperion together with MAI which tinkered with the 686B settings, eliminating all problems and proving conclusively that VIA's southbridge had been solely to blame all along. At the start of November the new patch had completely failed to fix the problem, and a new theory was offered. Now the story became that Hyperion had known all along of a powerful new feature in the Articia S chipset which reduced memory access latency. The Linux drivers don't cater for this feature, but MAI was working on a fix for it. Meanwhile Hyperion had of course written the DMA capable drivers for the AmigaOne (in OS4) properly all along. Then by December 2003 the story became that no OS4 IDE DMA driver had been written, although one was now in progress. Initial reports said that this driver, like the one written in 2002 was working 100% reliably. The Linux drivers were no longer of interest to Hyperion, and no fixes would be forthcoming from them. During Spring/summer 2004 an announcement was made that an OS4 IDE DMA driver did now exist, and was 100% reliable, but it couldn't be released for testing and would only be included in the final OS4.0 So basically at any time Eyetech and Hyperion might say nearly anything, but having changed their minds so many times I don't think even they know what the truth is, so it's probably best to steer clear altogether. Any NEW amigaONE Linux Kernel? : Comment 12 of 55 ANN.lu Posted by Thomas Frieden on 11-Aug-2004 15:29 GMT In reply to Comment 6 (Bernie Meyer): We were contracted to do an initial Linux port. Which we did. Which also means every Linux involvement ended then. So where's the frigging problem ? Any NEW amigaONE Linux Kernel? : Comment 13 of 55 ANN.lu Posted by Thomas Frieden on 11-Aug-2004 15:35 GMT In reply to Comment 7 (Bernie Meyer): > Quite unambiguous, and quite in contrast to the more recent position See my other post. We did the initial port. After that, our contract was fulfilled. And this was in fact Hyperion's last involvement with Linux. That's the thing about contract work. You do your job, get paid, and that's it, really. FIY, we were contracted by Monolith once to do some Windows related work. Does that mean the next thing we do is adapt Windows to the A1 ? Problably not, right ? Any NEW amigaONE Linux Kernel? : Comment 14 of 55 ANN.lu Posted by Fabio Alemagna on 11-Aug-2004 15:42 GMT In reply to Comment 12 (Thomas Frieden): > We were contracted to do an initial Linux port. "Initial" as in first, or as in half-working/malfunctioning? Any NEW amigaONE Linux Kernel? : Comment 15 of 55 ANN.lu Posted by Hans-Joerg Frieden on 11-Aug-2004 15:46 GMT In reply to Comment 6 (Bernie Meyer): My, my. Same old story. Funnily enough, I remember I already pointed out the following to you in some older thread about the same topic. I am surprised that you forgot that but readily remember things futher in the past. Selective memory? Hidden agenda? Whatever. So, especially for you, the long version. Someone was supposed to do the initial Linux port (can't remember who that was). Nothing happened. Thomas and me sat down over the weekend and compiled the kernel. Could load it. MAI wanted us to go on, so we did. Made an initial install ISO for installing SuSE on a Teron board (SuSE mostly because I used to use it on X86 as well). That's it. After the initial work was done others took up. Since my interest in Linux is rather low, I never invested any more work in it. I rather spent time on OS 4 again.

I rather spent time on OS 4 again." Good. It seems to me it is entirely up to MAI, if they want a version of Linux to run on their hardware, to organise it and if necessary pay for it. Any NEW amigaONE Linux Kernel? : Comment 19 of 55 ANN.lu Posted by Darth_X on 11-Aug-2004 17:09 GMT In reply to Comment 15 (Hans-Joerg Frieden): Selective memory? Hidden agenda? Whatever. I'm pretty sure that everyone who posts here, including yourself, has some kind of hidden agenda. Someone was supposed to do the initial Linux port (can't remember who that was). Nothing happened. Terrasoft? ftp://ftp.mai.com/maitest/Linux/ydl3/installer/ Since my interest in Linux is rather low, I never invested any more work in it. I rather spent time on OS 4 again. Hopefully you'll get a chance to port OS4 to a platform that can really take off, like a next generation game console or perhaps a new PDA/cellphone. Unless AmigaDE is going to reside on those platforms by itself with no OS4? Any NEW amigaONE Linux Kernel? : Comment 20 of 55 ANN.lu Posted by Ronald St-Maurice on 11-Aug-2004 17:13 GMT I am surprised that this issue is still around. IMO DMA on Linux should be a priority for MAI. Am I the only one that thinks this should have been resolved by now? I guess most Amigans have a Windows PC with them to browse the web.

Gee I was missing you deeply sweetheart! ;) Any NEW amigaONE Linux Kernel? : Comment 23 of 55 ANN.lu Posted by Johan on 11-Aug-2004 19:59 GMT 3d got nothing at all to do with the kernel, so there already is ati 3d support for the amigaone i suppose, probably not good 3d, but 3d.

So the update was released ? :-) Any NEW amigaONE Linux Kernel? : Comment 26 of 55 ANN.lu Posted by Don Cox on 11-Aug-2004 20:38 GMT In reply to Comment 19 (Darth_X): "I'm pretty sure that everyone who posts here, including yourself, has some kind of hidden agenda." My agenda is that late next year I would like to buy a new Amiga which is at least as fast as my Amithlon box, and runs more Amiga programs. The Amithlon is great but not compatible with several 68k programs that I want to run. So I want to see OS4 developed and bug free, and hardware that is faster than the current AmigaOnes. Any NEW amigaONE Linux Kernel? : Comment 27 of 55 ANN.lu Posted by Don Cox on 11-Aug-2004 20:41 GMT In reply to Comment 24 (JoannaK): H-J's point was that everybody knows it is a pre-release, so there was no need for that dig you included. Any NEW amigaONE Linux Kernel? : Comment 28 of 55 ANN.lu Posted by Bernie Meyer on 11-Aug-2004 21:24 GMT In reply to Comment 12 (Thomas Frieden): So where is Suse Linux for the A1? Because according to Ben, that's what you were contracted to do.Where are working DMA drivers for the A1? Because unless you consider the state of the art in linux/PPC to be DMA-less (which I assure you is not the case), you must have failed on that contractual obligation that Ben mentioned.Unless, of course, Ben was, shall we say, somewhat imprecise (to avoid terms like "blustering" or "bombastic", or even "exaggerating") in those posts. Which would be somewhat embarrassing, seeing how he called people questioning Hyperion's level of involvement in linux as "idiots".... Any NEW amigaONE Linux Kernel? : Comment 29 of 55 ANN.lu Posted by Bernie Meyer on 11-Aug-2004 21:46 GMT In reply to Comment 15 (Hans-Joerg Frieden): My my, that's what I call "spear-heading development in conjunction with several other valuable developers with A1 machines".How about Ben's "Strange. Must have been a different Hyperion with whom MAI contracted for their firmware and their Linux distribution.MOS - reality distortion all the way" comment? Has anyone ever seen "MAI's linux distribution" including anything from Hyperion?But of course, that was when Ben still thought he could get away with "It is my understanding that the April chip is nothing more than the revised Articia".And the classic "I have to add right away that we never encountered this problem [the ArticiaS "feature (BM)] even with our 'unfixed' boards during all our time that we have been using Linux PPC on the hardware. And we do this all the time as we are the ones producing the Linux PPC for Terrasoft to sell with the Teron CX boards"But the real clincher is comment 44 --- "This effectively means that all consumer targetted A1 boards will have the very latest Articia S chip. Any other boards will either be fixed or can be traded in." --- has anyone ever heard of an offer to "fix" or "trade in" their feature-laden board? And why, one might wonder, would Ben, the guy who is in some way involved with making software for these things, make announcements about trading-in or fixing of hardware?So if you are wondering whether I have an agenda --- yes, I do. I absolutely *hate* pompous assholes who either know that the crap they spout is bullshit, or know that they don't have enough of a technical clue to even think, let alone talk about the things they spout bullshit about.

[b] is bold, [br] is line break. Must remember my HTML.Apologies all round :( Any NEW amigaONE Linux Kernel? : Comment 31 of 55 ANN.lu Posted by Anonymous on 11-Aug-2004 23:45 GMT Can someone please state clearly: what will DMA support in Linux do for A1 users? Does it matter a great deal, or a little bit? Any NEW amigaONE Linux Kernel? : Comment 32 of 55 ANN.lu Posted by NoBeForMe on 12-Aug-2004 00:06 GMT In reply to Comment 31 (Anonymous): Currently, as best we can tell the options on the A1 hardware with Linux are 1. Switch off IDE DMA, disk I/O performance is terrible (unless your previous experience is with something out of the ark, like an Amiga or a RiscPC). When accessing the hard disks the machine will struggle to get anything else done. You may still experience crackle (audio DMA corruption), unusually high error rates for networking (NIC DMA corruption) and it's probably also dangerous to use SCSI (not many tests done). Quite a few people have disabled IDE DMA and continued to use their A1s, they seem more or less happy. Amiga owners have learned to put up with high prices and poor quality, and anyway they were looking forward to OS4. 2. Leave IDE DMA on, risk potentially unlimited data corruption, mysterious crashes, etc. Some people have done this too. A few claim not to have seen any corruption, on the other hand some of those complained extensively about mysterious crashes, weird problems no-one else could reproduce... draw your own conclusions.

Does it matter a great deal, or a little bit?" For current users who want an Amiga running AOS4, it will do nothing at all. Many have wiped Linux off their machines now that AOS is here. If somebody wants to sell large numbers of AmigaOne motherboards for some commercial use, then a fully working Linux would surely help sales. However, some applications might not use hard drives. I can't, personally, see why anyone wanting a machine to run Linux as a desktop OS would consider PPC.

Do have some silent ? Do be part on the 21st century ? Many people are using Linux as a desktop OS (some people are really mad, but some even use Windows !). As a result, this people may be interrested into a full working PowerPC workstation (which include Apple Mac and bPlan Pegasos, en exclude MAI Teron and Eyetech AOne which are thesame in fact). For example, the Apple iMac has a very interesting "All in One" designed. Pegasos has the advantage to use "standart" devices (like x86 Gfx card, common DDR RAM, FireWire...), and to use a small "MicroATX" format. So it can be installed in small (silent!) box and it still has some PCI/AGP slot available.

(Yes, I know about PearPC, but thatdoesn't get anything like native speeds any more than Qemu on PPC getsnative x86 speeds, though it's good enough for casual use in both cases.)Personally, I think the majority of flaky behavior is caused by not-quite-compatible RAM. In a few months it will be 2 *years* of no apparentproblems with DMA for me...except Qemu, that freezes the machine with DMAon, always, for some reason.

Were you trying to make a point? Perhaps that, yes, the Articia S does have DMA problems, and that still it remains to be seen whether these can really be worked around in software. The NIC drivers in OS4pre also seem to be problematic, but I don't think anyone in a position to know has blamed those problems on DMA, yet. Any NEW amigaONE Linux Kernel? : Comment 50 of 55 ANN.lu Posted by Davy on 13-Aug-2004 17:37 GMT In reply to Comment 49 (NoBeForMe): They were caused by a combination of my drivers not doing cache flushes and the IDE doing PIO mode which blocks everything.
