For anyone else that is looking to try this with AmigaOne version of AOS4.1Fe, I just saw the Alinea is apparently stocking it again. I was able to order it today. I have the same card that smarkusg used so I hope this will be the magic ticket to full emulation with a real GPU.

I had a response from Alinea, they are out of stock on AmigaOne version of OS4.1fe, so I'm just waiting for them to get more from Hyperion. I have the impression that these are low-volume sales, so they may wait until they get enough before ordering another round of disc to be made. (So wish we could buy digitally).

@smarkusg

Thanks, I'll email them. I didn't think about the tariff war going on. I wonder if they could just email the code for the one I buy and I download directly without getting the physical copy.

So far, only seeing Alinea and Amedia-computers show having the AmigaOne version in stock. However, Alinea says it doesn't have the quantity I want (jus 1), and Amedia says no carrier to deliver to that address (I used 2 different addresses in 2 different states.

I've purchased copies for Amiga Classic, Pegasos2 and Sam460. I think it's crazy that there have to different versions for each. I'm guessing it just a bootloader difference.

If anyone knows what the differences are or where to find one that ships to the US, I would be very appreciative. I'm considering trying the same gpu (Asus HD 7750) that smarkusg was using for his test but with the pegasos2 to see if that works better than the r9 270x and 2 different RX 580s I've tried.

Does anyone know of a retailer that is currently selling the AmigaOne version of AmigaOS4.1fe?

The Alinea shop seems to have it then says it can't be shipped in the quantity selected (which is just 1 in my case). Acube lists it as out of stock.

Any ideas? Shipping to USA

Does anyone know if the QEMU vfio passthrough works with the SAM460 version machine version and the OS4.1FE for SAM?

Swapping PCI slots is one way. The other is to use ACS-overwrite. This requires both a new kernel and some lines in the grub boot. I don't have the link handy that tells how to do that, butas for the ACS overwrite/patch, you just need ot install linux-zen as the kernel (I think I did that on arch linux using pacman -Sy linux-zen or similar... can be found online). Think it is similar on ubuntu-based systems.

After that, and reboot, etc, you will see only a single pci device per IOMMU group (you will have many groups). You can then just make a '-device ' entry in the qemu command line for just the video part and not bother with the audio if you don't want.

My only nVidia card isn't available to use for this project. I did try SDL and GTK and it was very snappy. However, my goal isn't just to run qemu emulation but to have a real Radeon card so that I can run things like CANDI and games just for the novelty.

Insulting me for not having time to catch up on forums posts isn't helpful. I'll post my qemu command line soon.

Sorry for silence. Been super busy on other projects.
So, the suggestion for using bochs-display to be fullscreen to capture mouse worked. At the same time, I noticed my mouse was way more responsive. However, installation of AmigaOS was still very slow. In fact, I didn't get to finish it, I gave up since it was taking so long.

I did swap to another RX 580 that I had (MSI brand), so I'm not sure if this contributed to the better/speedier mouse response. I will try again with a preinstalled Amiga OS4.1FE harddrive image.

I tried SDL and GTK and they were great. I personally am not trying to get the super-fast emulation, I just want to be able to use Warp3D Nova and the CANDI wallpaper apps that need real hardware. I'm also considering an older card like HD 7750 or so to see if those work.

I'll put in my results when that happens.

@balaton

Just tried using the bboot.fth script.

I had to use rdbtool to create a new disk image and copy over the files to the new drive in order to get the pegasos2.rom bios to see them: (modified slightly from your pegasos2 subpage



when it got to the point I could manually enter commands:



(Doing this without the vfio passthrough parts, and only using -device sm501, it booted okay (just no external graphics.

Switching by removing the sm501 and inserting the vfio devices:


I never get the opportunity to enter the boot command. Here is the output:

@white
The tests that did show the screen open were with the XFX RX 580. I have yet to get the Sapphire R9 270X to do anything other than reboot my computer when I launch qemu. It's on the latest firmware as well.

@balaton
I realized that I needed to get Enhancer and AmiStore had it less expensive and I was on my Windows side so I just launched AmigaOS4.1 in WinUAE since I had that set up.

I then copied the files out to USB, rebooted to Linux, copied them out, and rebuilt Kickstart.zip with them in place. Just a convenience thing.

Thanks for the suggestions on using pegasos2.rom. I'll try that next. I thought I had tried it and ran into an issue. I'll update. Thanks for all the help!

I have also noticed that I can only run the qemu command a few times before I get this error:

qemu-system-ppc: ../qemu-9.2.0/hw/pci/pcie.c:1024: pcie_find_capability_list: Assertion `next <= PCIE_CONFIG_SPACE_SIZE - 8' failed.

Only rebooting the computer will allow it to work again.

I plan to make a post about my efforts if they ever work out on my blog: amigafun.wordpress.com

Okay, so balaton's suggestion of adding -device usb-mouse and -device bochs-display seemed to work as far as mouse movement was concerned. The downside is that in order to capture the mouse movement, I have to only use it within a very small black window that pops up over the linux desktop. if I move the mouse outside that little box, the mouse pointer on the amiga monitor freezes until I get it back within the boundaries of that box.

When it did work, the system was VERY, VERY SLOW. I think this is something found in other threads so I haven't had a chance to read up on their solutions (if there were any).

I also went through so many changes that I'm not sure about making a step-by-step tutorial. I basically used the notes balaton made on this form as well as his Amiga-like OS's webpage with emphasis on the pegasos2 page.

Basics:

- Installed the latest archlinux on my AMD system (choose grub as bootloader)
- Followed VFIO and GPU passthrough tutorials on KSK Royal's YouTube page (turning on virtualization and IOMMU as well)
- Follow how he found the radeon vendor and model ids are added them to grub and regenerated grub bootloder.
_ He used Nvidia card, so I had to change the file /etc/modprobe.d/vfio.conf to use the vendor:model numbers as well as change second line to be `softdep amdgpu pre: vfio vfio-pci
- Had to make a new file in same folder vfio.conf called amdgpu with the only line being the same as the 2nd line of vfio.conf
- arch doesn't regen modprobe changes like ubuntu in his video so had to use one for arch: sudo mkinitcpio -P
- then had to install linux-zen using pacman -Sy linux-zen.
- added `pcie_acs_override=downstream,multifunction vmlinux=zen` to end of grub GRUB_CMDLINE_LINUX_DEFAULT line after vfio additions.

I had to use acs overwrite to break each pcie device into it's own IOMMU group. I had to do this because the 270x card was showing up with several other devices.

The command line was something like this:



Oh and I used WinUAE (Flowerpot) running AmigaOS4.1fe Classic to log into AmiStore and purchase/download Enhancer 2.2 to get the RadeonHD and RadeonRX chip files to include in the Kickstart.zip file. It was much cheaper buying it there than physical media from a vendor.

Model number RX-580P8DFD6

https://www.amazon.com/XFX-Radeon-1386 ... -580P8DFD6/dp/B06Y66K3XD/

The system I'm using has a Ryzen 5 5600x, and two GPUs:

XFX Radeon RX 580
Sapphire Radeon R9 270X

I installed ArchLinux to use Qemu 9.2.0 and set up GPU passthrough with VFIO. While trying to get the passthrough working, I wanted to use R9 270x with Amiga side. The R9 270x video and audio components were tied up in IOMMU groups with other devices and QEMU didn't like that, so I then implemented ACS write patch to break out each device into its own group (using linux-zen kernel).

I never got it to work, so I swapped to using the RX580 (by changing the vfio ids in the grub line, running mkinitcpio again) and I was able to finally see the Amiga boot on it's own monitor, but now the mouse is frozen in the upper left. I tried the bochs-display to capture mouse events but there was an error ... can't reproduce it now but mouse still frozen. Will next try to pass through a specific mouse device on the command line.

Another update: Decided to swap from the R9 270X to the RX 580, swapped back to bboot and Kickstart.zip instead of pegasos2.rom.

I can now see the AmigaOS4.1fe installer fullscreen on my other monitor. But the mouse isn't moving. Getting closer.

Anyone else have a frozen mouse on a fullscreen AmigaOS4.1 workbench via qemu?

Made some progress. The filesystem was complaining about the blank disk image I'd created. Using the instruction on this page (http://zero.eik.bme.hu/~balaton/qemu/amiga/aos_pegasos2.html), where I used rdbtool (from amitools), to create the harddrive layout, and manually copy the amigabool.of and other files to it, I'm able to then get to a prompt and do:

boot hd:0 amigaboot.of and it works fine

then, I add back in the vfio devices for the isolated gpu, and remove sm501 and I'm getting complaints about something else. I see errors and no prompt:

I've seen the command in the bboot readme about booting manually from Smartfirmware by using the command `boot hd:0 bboot.fth`.

I've copied that fth file to the same directory as the other files, I boot using the -bios pegasos2.rom file and when I try the command to boot using bboot.fth, I see this "filesystem not supported:

Any ideas what it is complaining about?

Early versions of AMIStore are looking good. Here's one of several favorable reviews:
