    Well...my G5s have both cost me $30 and $50 respectively, and I did have to rebuild the cooling system ($5 for four o-rings and you only need two)...so its not nothing ;-), but it IS the best value I've ever had in computer hardware.

    And I've got this 11,2 sitting here humming away running Linux, which it does almost as well as my X64 hardware, which makes the arguments against porting MorphOS to these systems doubly frustrating because its 'low hanging fruit' and it would leap frog us over A-eon's offerings in performance and price (the highest price I've seen for an 11,2, which was completely refurbished, was $300, so we are talking about half the price of a Tabor board alone).




    In the case of the 11.2 G5 PowerMac Quad G5, I think it should have been supported instead of the X5000, but understand why some users prefer to buy new hardware. Myself, I like getting extended use from old things, because I so strongly dislike how most of our societies have become too wasteful, and throw away things that still work perfectly well, just because something a tiny bit better has come along. This is specially true in the computer world, where things improve at such a fast rate, and everyone wants to have the latest and greatest stuff. I guess this is partly why I am still an Amiga user, because I enjoy making it do things it was never designed to do, but make it continue to be useful.

    Given that so little work seems to be needed to complete a version of MorphOS which could support the 11.2 G5, I will be surprised if we don't see a bounty to complete and release support for it some time in the near future. Specially since it will be able to take advantage of PCIe video cards which will already be supported in MorphOS3.10.

    So, hang in there Jim. You have a good chance to get your wish granted "someday" in the future, but it might take a bounty to get it done. I probably won't get one, unless I see a quad G5 locally that is free, or almost free to pick up. If MorphOS suddenly (and unexpectedly) some day gets a version which can use more than one CPU for any task, then I might reconsider (it would need to be able to use more than 2 CPU cores to make it better than my current dual 2.7GHz G5). Either that, or if I decide that the better video card performance allowed by switching to a PCIe video card, makes it worth getting rid of my dual 2.7GHz G5, and switching to the quad G5.

    Hey, I'd contribute to a bounty.
    I'd even consider a flight to Germany or South Africa to camp out on either Frank or Marks doorstep and beg for it on my knees.
    It would just be a really kick ass MorphOS system.
    The 11,2 can even be upgraded to SATA3 (with PCI-E X4 cards).
    It can handle dual video cards (which only the X1000 can do), and even with two video cards its still got two X4 PCI-E slots to spare.
    If you really wanted to get weird (the system could support four video cards), if you used cards that supported 3 or four mintors, that 12 to 16 separate displays from one computer/

    And No other NG system has the capability of supporting a full bandwith SATA card (unless it might work in an X1000's X8 slot), as you need a controller with more than one PCI-E lane (as an X1 slot doesn't have enough bandwidth).

    Look, its ideal for our OS, plain and simple.

    If potential support for PowerMac11,2 won't span over all models, I'd prefer the slower dual-core ones to the quad-core one, because I prefer air cooling over liquid cooling.

    ...or have been supported since MorphOS 3.8 already, which added compatibility with Sam460 and Radeon R500 (2D+3D). In a PCIe-capable MorphOS machine, I would take a 3D-supported R500 card over any 2D-only supported higher card any day. But that's just me :-)

    What makes you think we won't get 3D support above the R500s?
    The R500 cards were the last to support 2D primatives.
    So all the 2D code Mark is creating currently uses 3D commands.
    And he has admitted that this will make writing the 3D part of the drivers easier.

    From that comment, I'd assume 3D is a goal.

    As to the 11,2, I want the 2.5 Quad, and yes support for air cooled model should be included as well for the timid (or in my mind, overly cautious, if that makes you feel better).
    Personally, I've never had a water cooler failure, but then I followed David's suggestion and rebuilt them on receiving them.

    I'd also have no problem installing a water cooler in an X64 system, and that is the likely route I will take for Ryzen.

    But, I'm glad to have one of the sharpest minds posting here on my side on this issue ;-), 11.2 support ought to be pursued.

    What about the X5000's x4 slot (the one behind the PCIe-PCIe bridge)? Wouldn't a normal PCIe x16 card work in it? (Btw, I also found R500, R600 and R800 cards with PCIe x1 connector).

    Yes, full-speed SATA3 needs 4 lanes of PCIe v1 or 2 lanes of PCIe v2. So what about the X5000's x4 slot (the one behind the PCIe-PCIe bridge)? Wouldn't a SATA3 card work full-speed in it, even if it was somehow limited to x2 speed by the bridge bottleneck?

    X5000's x4 slot is blocked by any video card wider than single slot.

    Would it, as its multiplexed?
    I don't know, I'm not sure I'd want to see the benchmarks.

    BUT video cards work in the G5's X4 slots, so you have a point.
    And talking to guru Hans, I did confirm (from tolsm's own benchmarks no less) that the X5000's video drivers aren't using DMA yet (and they're still as good as the SAM460), so look for that situation to improve.
    Also, I'm convinced there's got to be a firmware issue behind the low memory benchmarks.

    BTW - Where'd you find the X1 video cards? The only X1 cards I've seen were AMD FirePro cards and similar designs primarily intended to increase the number of displays (a video card running through an X1 connection would definitely be crippled in performance).

    But yes, I've seen them too.

    I guess you could say anything with an extra PCI-E slot (even if its only X1) could handle an extra card.
    I'd just install a primary card that could support more monitors (like AMD's Eyefinity concept).

    BTW - I just did a quick comparison between the P1022 and the T1042's SerDes I/O lines.
    You know, even though the T1042 only has two more SerDes lines, its bus operating frequency (twice as high) gives it about 267% of the performance of the P1022?

    6 SerDes lanes at 2.5 GHz vs. the 20 lanes at 5 GHz of the P5040...buying Tabor is just not that great an idea.
    I mean, we're already arguing if the X5000 is I/O limited.

    Then again, the only thing that comes close to the 11,2 is Freescale's T4240RDB, since the T4240 has 32 SerDes lanes at 10 GHz.

    There are PPC processors that could be used to build a decent lineup for NG, the T1042 at the low end, T2080 for a mid-range model, and something from the T4 lineup (like the T4240) at the high end, OR even the Power9 (as in the TalosII). We've discussed these, I can accept the P50XXs in the X5000, and hope the T2080 laptop makes it.
    But a P1022 based board in 2018?

    Mmm, since they're almost ready, how about the X5000 port and the 11,2 port, and then let's hit the road running for X64 (Ryzen maybe).
    'Cause its not getting just crazy around here, its getting STUPID.
    And I have some tolerance for crazy, but stupid is just plain irritating.

    It takes some work to set it up for Linux.
    Your easiest course if you want AMD graphics is one of those Apple X1900GT everyone keeps saying aren't available (although on any given day I can usually find listings for two or three of them).

    If its the water cooled quad, get a t-handled hex wrench, pull them cpus and rebuild the cooler.
    If not you're probably good for another 12 years if you just blow out the dust. ;-)

    BTW - How much did it set you back?

    Nothing. I just said I would always prefer an older and slower card with 3D support to a newer and faster card without 3D support. For instance, if PowerMac11,2 support was introduced soonish and 3D support wasn't extended since MorphOS 3.8 at that time, i.e. not available for anything newer than R500, I'd use that PowerMac11,2 with an R500 card instead of a newer card.

    > I'd assume 3D is a goal.

    Yes, of course it is. But judging by the really small list of things still lacking for a potential PowerMac11,2 port, I guess that *could* be released before 3D support for anything newer than R500 was finished.

    > 11.2 support ought to be pursued.

    Absolutely :-)

    So what? Single-slot graphics cards supported by OS4 are widely available, so this doesn't render my questions invalid.

    3D might be delayed, I don't know.
    Its an unspoken thing with Mark that I don't ask, and whatever he cares to mention...well that cool.

    I do know he works on this stuff maybe a little more than he should, after all he's married, and any guy that changes continents out of love...I just have a soft spot for that kind of stuff.

    You know, Mark's not just a top notch programmer, he's a very good guy (better man than me, I assure you).

    I'm REALLY looking forward to this next release, the little I already know of it...its going to be cool.

    I'd assume this is the PCI-E to PCI-E bridge, the link doesn't work for me, but you included the part number, so I'll find it. I figured it was an IDT component, so this confirms it (plenty of PCI-E to PCI bridge vendors, not so many for this type of component).

    >https://www.diodes.com/assets/Datasheets/PI7C9X111SL.pdf

    PCI-E to PCI bridge, link works, got it. Thank you.

    Thanks for the component listing. I've been bouncing the idea of a PCI-E bridge chip off of Roberto Innocenti (from the T2080 laptop project), since I actually think its a smart move.

    Does Tabor use anything like this first bridge? I would certainly help, considering the limited number of SerDes lanes.

    In any case, for a technical junkie like myself, good stuff. Again, big thanks.

    Edit - Its better to provide the page where the download link (for the first component) is provided.

    Still, really f'ing neat stuff.
    Thanks Spectre.

    > Would it, as its multiplexed?

    I think so, as I doubt that multiplexing reduces the nominal bandwidth by more than 50%. There are 4 input lanes to the bridge, so using x2 bandwidth for a SATA3 card in the x4 slot leaves another x2 bandwidth for the remaining two x1 slots and the PCI bridge with two PCI slots. This means that using further cards in the two x1 slots (or in one x1 slot and one or two PCI slots) would be within the bandwidth of the PCI controller and the SATA3 card wouldn't be slowed down. Just when the two x1 slots *and* one or two PCI slots are occupied by cards, the 4 input lanes have to be multiplexed to more than 4 output lanes, so bandwidth would likely not be enough to sustain full SATA3 speed anymore.

    > Where'd you find the X1 video cards? The only X1 cards I've seen were
    > AMD FirePro cards and similar designs primarily intended to increase the

    Yes, FirePro and FireMV. In EU online stores, I find currently available new:
    - FireMV 2250 (RV516) for 56 EUR
    - FireMV 2260 (RV620) for 89 EUR
    - FirePro 2450 (RV620) for 271 EUR
    - FirePro 2270 (RV810) for 113 EUR

    > I just did a quick comparison between the P1022 and the T1042's SerDes I/O lines.

    Regarding P1022:
    The P1022 on the Tabor/A1222 riddles me. A-Eon claims one PCIe x16 slot with x4 bandwidth for Tabor. If we look at the possible SerDes configurations for the P1022, we can see that the most sane configurations for PCIe that allow both SATA and Ethernet are x1 x1 x1 (0x06) and x2 (0x0e). This means the x16 slot could have x2 bandwidth at best, not x4. The only option that provides x4 bandwidth for one PCIe controller would be x4 x2 (0x1c), but this lacks both SATA and Ethernet.
    Even if we assume that assignment of the P1022's 6 SerDes lanes was completely arbitrary and not restricted by predefined configurations, PCIe x4 + 2x SATA + GbE would obviously require 7 SerDes lanes.
    Something seems not right here. Any ideas?

    Regarding T1042:
    If we look at the possible SerDes configurations (or there, page 37) for the T1042, we see that the most sane configuration is 0x08 with x4 x1 x1 for PCIe, also providing 2x SATA as well as Ethernet (via "Parallel Port").

    > 20 lanes at 5 GHz of the P5040

    ...of which max. 8 can be assigned to PCIe.

    > the only thing that comes close to the 11,2 is Freescale's T4240RDB

    The T4240RDB has one x8 slot and one x4 slot (both at 5 GHz / PCIe v2), so only 50% of slots, 37.5% of PCIe lanes and 75% of PCIe bandwidth. The T4240QDS, which has up to four x4 slots and thus 100% of slots, has only 50% of PCIe lanes but 125% of PCIe bandwidth.

    > the T4240 has 32 SerDes lanes at 10 GHz.

    ...of which max. 16 can be assigned to PCIe (twelve at 5 GHz / PCIe v2, four at 10 GHz / PCIe v3).
    (Beside, the T4241 is to be preferred.)

    > since they're almost ready, how about the X5000 port and the 11,2 port

    I think the X5000 port *is* ready, or isn't it? :-)

    I already linked to the PCIe-PCIe bridge two weeks ago. Can you quote the information from the datasheet that answers my specific questions?

    > PI7C9X111SL

    Again, what has the PCIe-PCI bridge to do with my questions?

    When I linked to this same page two weeks ago, nobody seemed to care ;-)

    I don't think so as it has just one PCIe slot and apparently no other on-board components connected to PCIe.

    I was raising a point based on the the models of video card that Jim talks about using so that reply was really pointed in his direction .

    I am looking at a page from the Cyrus Technical Reference Manual.
    I am not an engineer so somebody correct me if I am going wrong.

    The 1 x PCIex4 ,3 x PCIex1 connect through 4 lanes of the P5020/P5040 via the 89H12NT12G2 PCIex-PCIE switch and the 2 PCI slots connect to the 89H12NT12G2 via the PI7C9X111SL PCIE-PCI so if I understand correctly everything is going to pass through 4 lanes to the cpu .

    What would the impact of say transferring data from a drive attached to a pciex4 sata 3 card to a drive attached to a pciex1 sata 2 card while playing audio from internet radio with a PCI based network card and pciex1 Audio card ?

    If you transfer via the pciex4 to the onboard sata no problem ? or if you do the internet radio and transfer from the pciex1 to the onboard sata also no problem ? .

    Yeah, I'd be for it.
    Just bought a 11,2.


    It takes some work to set it up for Linux.
    Your easiest course if you want AMD graphics is one of those Apple X1900GT everyone keeps saying aren't available (although on any given day I can usually find listings for two or three of them).

    If its the water cooled quad, get a t-handled hex wrench, pull them cpus and rebuild the cooler.
    If not you're probably good for another 12 years if you just blow out the dust. ;-)

    BTW - How much did it set you back?


    It's explicitly meant for MorphOS. If support for it doesn't come with 3.10 I'll sell it, or I'll keep it with macOS Leopard for my daughter.
    Probably I paid a little too much, ~100. But it's it good shape, clean, no scratches, etc.

    From what I know the support won't come with 3.10 (if at all). It's way behind schedule to delay it even more (and supporting the PCIe G5's would mean a further delay for the team).

    @Andreas_Wolf

    A while ago I tried a pciex16 video card in pciex1 slot via a pciex1 to pciex16 adapter but the X5000 would not boot any of the combinations that I tried. Primary Card in pcix16 slot
    X5000 would not boot even with just the adapter and no video card attached with the primary card in the pciex16 slot.
    Second card in a pci slot with pci to pciex16 adapter would boot. Worked but was slow under linux but crashed while workbench was starting up under AmigaOs 4.1

    Okay, so you hit the wrong "Reply" button and quoted the wrong message twice :-)

    Yes, that's what I wrote in comment #40 of this thread, two weeks ago in that other thread and two months ago in yet another thread :-)

    As I wrote in comment #40, I *think* that the bridge and the SATA3 card could negotiate to use only 2 of the 4 connected lanes, which would still be 67% more bandwidth than required for full-speed SATA3. In your scenario, this would leave x2 bandwidth for the x1 SATA2 card, the x1 audio card and the x1 PCI bridge (with the NIC). This means that the 4 input lanes would have to be multiplexed to 5 output lanes, so bandwidth would likely not be enough to sustain full speed for all cards anymore.
    I don't know what would happen, but I can imagine that the x2 connection between bridge and SATA3 card would be re-negotiated to x1, resulting in reduction to 83% SATA3 speed, but freeing one more lane so that there are 3 lanes for the other three cards connected by x1.

    I guess so.

    Did not see post #40 when I was typing what became post #43.
    Was looking at the reference manual page so took my time before pressing submit.
    Sorry also was not following the bridge info in the earlier part of the thread .

    That's strange as such adapter should be just a dumb extension of the x1 connector (and the other lanes electrically dead or not even there).

    Yeah. This was a highly speculative task to buy this thing. Probably a bit passion driven in the hopes that 3.10 would add support for it.
