I wrote it after reading the OpenFirmware PCI doc I've linked to above. Maybe also check the Marvell Discovery II docs as that provides the PCI bus on pegasos2.

These are from libpayload as can be seen in the comment at the top of the file.

Did you try if you can access the card behind the bridge with config-l@ config-w@ and so on from the SmartFirmware prompt? Maybe you're just passing the wrong address to the RTAS function that's why it does not read the right bus.

Re: Attempting to upgrade Sam 440 with an R7 240 or HD 7770

@Hypex

You know I was referring to modern gen Amiga systems right? lol

I mean, if I were to try another card, it would be a 7450, as that card requires the same power to run as the 5450

HOWEVER

According to geennamm, it doesnt have backward compatibility for 5v, meaning, despite me having ample PSU power, without an rail adapter, it still wont work.....

Alas, back to square 1, I either go back to a 9250, 9200, or grab the 460le, and use its pcie slot.....

Albeit having said that, I'd have to double check with the community here if the 460le would be able to run a r7 240 or whatever without an adapter with its pcie slot thats included, knowing my luck in Amiga land, nothing will be that simple.

:D

This isn't windoze Hypex, ofcourse it isn't included.....

They even only included an extremely basic Radeon HD Driver with Amiga os4.1FE release, what about all the people that may have already upgraded their cards and did not keep their 9250 or whatever???? lol

I could continue but I won't, as I really am a little hopeful that Amiga Os4.1fe is still under going development to see the light of perhaps Amiga OS4.2 or Amiga os 5.0, LOL

Call it being in dream land or la la land if you will, but the hopefulness is still there.

I'm even hopeful they've re-coded it all to be able to be on more accessible hardware for all of us that remain, I dont mind if it went ARM even, if this is an easier plausible action to complete.

Anyway, I suppose maybe thats why they released the first enhancer for free to allow users to atleast have a driver that could work with some of their more basic cards that werent 9250s?

I don't know of any docs on pegasos2 specifically but there are some docs on OpenFirmware here: https://openfirmware.info/Bindings and on PCI there are many on the net. You may also look at some BSD sources but not GPL code if you want to use it in non-GPL closed source project.

Well actually, if you can get both online normally, there both on the network.

But networked over a cross link, well, Miami was good for that like a Mac with internet sharing features. I gave up on that almost 20 years ago with Roadshow. It just needed too much manual work. Where as with Miami or MiamiDX it may have been, it was built in, it just needed one Amiga to connect to the other and both were online.

Quote:

Albeit having said that, anyone who's used a mac before will probably find it relatively quick and easy to understand and even possibly get annoyed at the OS for not auto arranging icons, for example, when opening up a drawer.

Yes I find that annoying these days as well. And even after the three actions needed to it, it can still not look right after. The reason it's like that is to avoid writing to disk. Since AmigaOS started as a floppy OS. And this avoiding of writing has continued on, though it may seem quaint now, so the disk isn't constantly thrashed. This is evident in the design of specific save/use/cancel in requesters where as in other desktops, which I also see as confusing, the close window action actually saves. The AmiDock tends to save on change though which differs from standard AmigaOS practice.

@Gregor

Those values are measured with the ADC inside a serparate microcontroller on the X5000 mainboard (Atmel). The OS (OS4 or Linux) has no part in that.

Those ADCs are generally bad and don't specify items like gain and offset drift. So don't expect multimeter quality values.

So looking at what you've written here, its basically not comparable due to how Amiga OS works with these cards versus any other modern operating system that actually has support basically.

Yes, pretty much. And also something I forgot to mention. How the card interfaces with the computer matters as well. So a 9250 PCI is designed for a PCI system and can work well. The Sam supporting a 66Mhz would help if it does have full support. But a 5450 and above with a PCIe interface needing a PCI bridge would have a bottleneck. Some 5450 cards had PCI interfaces on the hardware but I don't know if they would perform any better being a legacy interface.

My XE, though is has a 66Mhz PCI slot and AGP, doesn't miss out on bottlenecks either. The 66Mhz slot, it it can work, is not plug and play, needs some config in UBoot and conflicts with AGP. The AGP is set at 2x speed, but in reality, only works at 1x speed. Also, funny enough, when I set it up and bought my 9200SE with 8x AGP from a normal computer shop, I sent messages about it to OS4 people, and was told an 8X card will never work in my XE AGP slot. I forget the details, but I plugged it it in, and it worked fine as it does now almost 20 years later.

I'd expect for the PassMark tests that the PC hardware plugged in, especially PCIe, was plugged into a native PCIe slot. Working at full speed. With drivers optimised for maximum efficiency.

Quote:

is there a web site that shows comparisons to what Im getting with a card on a system compared to other users using the same card?

Well, yes, that would be results on the HDRLab site Joerg linked too.

The Composite 3d demo could also be good to test as well.

Quote:

Im baffled why the community didnt continue with the idea that WARGUS put upon the community, a user may have an original CD, and there fore could physically install the copy....

Well, they still do for some ports. Wargus is one example. There would be others. A recent example is the Quake 2 OS4 update which uses a PC CD for data files. But that one is strange, as it's a paid product update of the Hyperion port from years ago, that needs the data files. I'd expect if paying for a game that it would all be included.

That's true... When I have followed the voltages with MCUinfo, the values have been very stable. There are only four values in which there is a constant 10mv 'flip-flop':

Voltages (mV)

CPLD: 3320
XenaXorro A: 3300...3310
XenaXorro B: 1010
PCIe: 1000mv
Main 3.3V: 3350...3360
Main 2.5V: 2490...2500
Ethernet: 1200...1210
Platform: 1030
Core A: 1200
Core B: 1190
DDR3: 1490
Serdes: 1820

But the base level has not changed.

Quote:

And you asked about replacing parts.. low voltages can be caused by the supply (regulator) or by excessive load. chips that draw too much power get noticeably warm.. but history puts the odds on a flakey regulator, which may not get warm at all.

These shutdowns has appeared totally randomly, both after the computer has been on for a long time, and just for a few minutes. That suggests there is no temperature issue, at least. Also, I have had both AmigaOS and Linux running when the issue appears, so the OS does not seem to affect it directly.

I of course tried and pure base install from netiso, and with manual typing of correct mirrors working today (archive...something, and it dl stuff from net when install), but in any case it fail. But from dvd1.iso all goes well. Its like net install is broken in some way and didnt manage properly to do post install steps to make system to boot.

But so far dvd one works, that enough for our tests :)

I forgot that Debian 8 "jessie" was ported to the archive in 2020.
The Net installation (netinstall.iso) even if you can't download packages contains the "base" core packages.
It should install itself. It is possible. that in case of correct apt/sources.list entries it does not complete the installation correctly.

If you need to install any packages, use the packages from the install DVD. The entries should be apt/sources.list.

@balaton

I took a quick look at the BBoot source-code. Is it accessing PCI configuration registers via register accesses instead of using OpenFirmware's function calls for that?

If so, is there documentation on how it's done?

The major problem blocking the use of RadeonHD/RX cards on the Pegasos-2, is that attempting to access its PCI configuration registers fails. Reads return either 0, or 0xFFFFFFFF, and writes fail. This is using RTAS calls.

From kas1e's tests, it looks like Linux may also be unable to access the configuration registers.

The Pegasos-II firmware was clearly able to access the device's config registers at some point, or the device wouldn't be listed in the device tree.

If there's documentation on how to read the PCI configuration registers of any device directly (i.e., without RTAS), then we may have a chance to get it working.
