Do you have something different from my network configuration? I also tried to set a MAC address, in case that helped, but nothing. It seems like the problem is not from the OS4 but from QEmu.

Is anyone else having the same issue?

You can try it via vmnet it is a bit more direct but also requires sudo rights.

-netdev vmnet-bridged,id=net0,ifname=en0 -device rtl8139,netdev=net0

You may have to reinstall it on Linux and I'm not sure how it's done, but please try that.


The network over vmnet under linux is of course nonsense as this only works under MacOs, sorry.

I'm currently using this to get an external IP without needing to configure a static IP

Just do the classic guided configuration automatically with RTL8139 without adding dns and other parameters.

you can assign any IP you like:

example:
sudo ip tuntap add user (your user) mode tap
sudo ip link set tap0 up
sudo ip addr add 192.168.0.1/24 dev tap0
sudo iptables -t nat -A POSTROUTING -s 192.168.0.2 -j MASQUERADE

then in qemu:
qemu-system-ppc -cpu 7457 -L pc-bios -M pegasos2 -bios /home/white/Scaricati/pegasos2.rom -m 1024 -serial stdio -device sm501 -drive if=none,id=hd,file=/ home/white/Scaricati/32gb.raw,format=raw -device ide-hd,drive=hd,bus=ide.1 -device rtl8139,netdev=tap0 -netdev user,id=tap0,net=192.168.0.1/24 ,dhcpstart=192.168.0.1 -nodefaults

no speed loss is same as virtual router configuration like 10.0.2.15 for example.

(( if desired, dhcpstart=192.168.0.1
you can also not put it in qemu you can do your own tests ))

The emulation is really good.

Too bad it doesn't work AmiCygnix I tried several days to make different configurations and accesses.

so I assume the problem is either in the graphics driver in qemu or in AmiCygnix.

I created a KVM machine to use Amilator via FS-UAE and it works perfectly.

So SSH Server is configured fine.

i have some questions anyone use wazp3d with qemu ?
when to use video players do you use Comp or SDL ?

anyone use E-UAE with qemu ?
which version do you use?

Thank you

I would like to make a long video just to show in a practical way what happens in the use of the whole more "technical" system to further improve the emulation.
I imagine further changes to "SDL" may bring other emulation benefits.

But I wonder who is interested ?

Knowing your crazy videos I would personally like it. It would be interesting to see what is currently possible and how well or badly it runs to encourage other interested parties to test it.

But it should not be too crazy and maybe only show the pure usage of AmigaOs4.1 under Qemu Peg2.

I did some simple tests with E-Uae under AmigaOs4.1 and I think that E-Uae SDL seems to be the fastest at the moment.

But I can't say exactly, I haven't had time to set up a proper configuration under AmigaOs4.1 with E-UAE.

Yes, it's just the SDL version of E-UAE that doesn't work as I would like
If it works for you you should see the "UAEGFX" driver among the resolutions to choose in the "Workbench" once Picasso96 is installed, also the version on aminet.

(don't install "Picasso96" with the latest versions of E-UAE otherwise the installation will hang )

You should use early versions of E-UAE or use WinUAE is build what you want.
Just remember to use Dopus to move the "Emulation" folder
Otherwise it will lose its properties

if you use Winuae rename the .raw extension to .hdf it will not lose its properties and then once you do what you want you can rename it again to .RAW



I use -cpu g3 and get the SDL version without problems
But if I use -cpu 7457 the screen has smudges.

Can you verify this?
With -cpu 7457 ?
Do you have "UAEGFX" active without problems?
With the screen without smudges ?

Also some programs conflict with the audio
Apart from Odyssey which always gives the same "OWB media player" error with relative "DSI"

This also happens with the new ScummVM with some games after using it.

it also happens with AmiCygnix

Do you have these problems too?

Thank you.

I would compile the 7457 disabling "ALTIVEC" if possible just to try.

Performance apart from "AmigaOS" Desktop does not seem to suffer in terms of speed between -g3 and -7457 for example with ScummVM and other applications.

Do you also have problems with the audio as described above?

Thank you.


(( If you don't have these audio problems then there is something wrong with "pulseaudio" in qemu x86 x64 version ))

I should also point out that I did a clean kubuntu install just to use qemu.

The problems are identical, also kubuntu is a brick compared to kali-linux which is really light and not yet deactivated some services which honestly I don't need in kali-linux.

E-UAE if configured correctly with SDL and with Picasso96 installed you should see it like this:

Here I'm using -cpu G3:
https://youtu.be/tecgSKKZ_yQ


here if i use -cpu 7457 any preference i set to "SDL Prefs" has no impact on E-UAE :

you can see the smudges:

here I made a test using only the -cpu G3
for me it is a new very fast emulation.

I have not yet "assembled" the whole OS 4.1 system to use it definitively.

But here I did some tests with Scumm Grim Fandango etc.
Internet some TwitchTV music and other things with E-UAE

But I'm very happy it's really nice for me to see that 4.1 is usable now.

I plan to dedicate an SSD partition to it now that sfs works.

I compiled the e-uae versions for you from this repository -> https://github.com/khval/e-uae-1-0-0/tree/catweasel

It should work for you on a QEMU g4 with SDL.

The e-uae itself on *Linux is much slower than fs-uae, so don't expect miracles under QEMU.

https://we.tl/t-lCqirbJnJQ

There was one project from "khval" which works really nice. It used AmiGfx not on SDL. But the project is unfortunately no longer developed.
I have a silent hope that the author is working further in seclusion and one day will show his version of e-uae on AOS4

Thanks works with -cpu 7457
Now the smudges are no longer visible.

Unfortunately it is slow

This version with the speed of the previous SDL version would be ideal
Because the smudges are gone.

Thanks for compiling, I will test it later.

I would be much more interested in what you left out of your compiled build to solve the problem.

What changes did you make or omit from this build?

In the Youtube video it looks very slow indeed...maybe you didn't compile the JIT translator or the SDLGFX drivers?

I am sure we can solve the problem.

Don't worry, we are already in the emulations column and since it is an emulation it should be okay to share our experiences here.

Your workbench looks a bit chaotic

Thanks for the video it still clearly shows how fast the whole thing runs. And don't worry about the current problems that are still there, many things have already been improved and there will be some more.

As already mentioned I use Qemu under MacOs and here there is no pulseaudio or so but coreaudio, but I will also do some tests if I can reproduce the errors under my system.

Could you explain me again how you set up twitch tv under AmigaOs4.1 ?

In the video there is a compilation with "khval" without SDL only with AmiGFX. It is with "JIT"

Here is the thread: https://www.amigans.net/modules/newbb/viewtopic.php?topic_id=8397

Amiga OS 3.2.x takes a long time to boot. On a real classic Amiga it is the same.

The speed is like on a bare A4000, so you can say it's a real hardware emulation

I won't share the files of this compilation, because it's a bit buggy

The e-uae project I think "khval" has been terminated as I wrote and I regret it terribly.

You could ask here if you can get help if you have already compiled it and it already works even if it has bugs, there are also many nice AmigaOs developers here.

I was also helped with MilckyTracker, SDL2, ScummVM we are still AmigaOs4.1 users even if it runs over an emulation.

When I watched your video I was surprised that you could watch YouTube in a pretty big window and smoothly.

I don't know what I changed, but it works just as well on my machine. Before I saw your video, I had always kept the window content quite small, which is not necessary. Thanks again for your video.

Here again the comparison:

The Sm502/1 which is also used in the Sam460 as graphics unit does this chip support 32bit output on real hardware or is it limited to 16bit there too. ?

Following up on this, the problem is that the emulated hardware is an SM501, which is limited to 16-bit colour output. We're lucky that the SM502 driver can handle the SM501, or it wouldn't work at all. We could get 32-bit if the SM502 were emulated instead.

I'm surprised too. I've just installed AmigaOS 4.1 on the Pegasos II using the amiga-news.de guide, and everything feels painfully slow compared to real hardware.

Are there any settings that you guys use for better performance? Or have things improved in the latest betas? I'm using the latest stable release (8.0.0.0).
