"Thank you for the information, Joerg, much appreciated. I've missed a few years of developments due to family and work, and your input has been very thorough and has filled all the gaps. Thanks again!"

Balaton,
There are some missing 'signals or functions' on the Pegasos chipset. In fact, many have tried using a PCIe → PCIe adapter to run modern graphics cards on the Pegasos 2, and I remember that not all cards managed to work—except with a patch for the customized OpenFirmware. I'm recalling this from memory, but I believe others could confirm it.

"I believe it would be more appropriate to test VFIO on machines that have a native PCIe architecture, such as Sam or e5500. In fact, our friend, in my opinion, should first manage to run Linux PPC with VFIO on an x86 host, especially since Linux already has a kernel with modules prepared for this, and then move on to AmigaOS, which is less digestible by emulation/virtualization systems.

@all.

PPC 60x, 7xx (motorola), 6500 (NXP), Power (IBM), PA6T (Semi) are book3s

PPC 4xx, PPC 5xxx (nxp) ,1222 and so and so are book3e

you cant paravirtualize (kvmpr or kvm) Book3e in Book3s and opposite.

if you are speaking about pure emulation all PPC or X86 or Arm can emulate a PPC Mac... you need Qemu and you can have it on all systems.

If you are writing about Virtualization or paravirtualization only 603 or 604 "amiga" can virtualize a PPC Mac but the host os have to be linux. If i remember good only AmigaOne Xe and Pegasos 2 can run Linux with MOL.

@Hans

Never have issues on Sdl or GTK with Gl=on under Qemu X86 guest on X86 host.
with PPC guest on X86 host you will find issue with strange colors with gl=on i think because bit swapping endianess.

The same endianess is present if you run an X86 guest on PPC host with gl=on.

I dont know other issue, i suggest to compile and run NOT the last one version.

Ciao

Try just with only this

qemu-system-ppc \
-M amigaone \
-device VGA,romfile=VGABIOS-lgpl-latest.bin \
-device sm501 -accel tcg \
-drive if=none,id=cd \
-device ide-cd,drive=cd,bus=ide.1 \
-drive if=none,id=hd,file=AmigaOne.img,format=raw \
-device ide-hd,drive=hd,bus=ide.0 -m 2048 \
-device es1370 \
-rtc base=localtime \
-device rtl8139,netdev=network01 -netdev user,id=network01 \
-display sdl \

@Fairdinkem

for what i sow in wii/game cube emulation on PI5, with PIStorm you will have a better performances compared old Sam Mini ITX if the delphine Jit and Video accelleration will be used for emulating PPC hardware.
For sure you will be able to run AmigaOS4 Classic better than Classic amiga 4000 with PPC 640e 233 on amiga 500 with pistorm and ppc jit.

You can have it if some one will make it... by the way

VirGL i can say for sure was working on Linux PPC plus i was able to build it but not tested on Linux Arm (raspberry).
This mean if KVMpr and Virgl together will work on PPC Linux host machine we will have a good base for new devs and extra users for AmigaOS.
On Linux Arm i was able to build and use Vulkan (3y ago). where i had success to have Linux X86 inside a blob with full Vulkan 3d acceleration support.
This mean we can have a good start in future for have a SDK Amigaos vms machines an arm or on other hw architectures if some one take the right decisions.

@Hans

KVM and Virtio is only for Linux users.
Use It will mean have a good skill in linux.
By the way will be a good thing if we think about cross developing something inside VMs with multiple istances on a single machine.
For sure it will help developers.
In future i can see a good official distro on usb amiga brand stick with AmigaOS4 with all sdk in sell by Hyperion resellers.

@kas1e
Good job!
i dont know if is possible to hack system timer speed on Dosbox ... but if possible try to set it with different value there.

on softwindows i have have this result with a small hack
https://youtu.be/h3j-5i1GO3g?t=168

the machine will gave in console eg 10 fps on quake but in reality it will be 1800 fps...
this had make me have on G5 f1gp 2 at super great performaces

@kas1e
Quad g5 mate 32bit dosbox patched frameskip 0

timedemo demo2

quake 320x200 scaler none 16.1 fps
quake 320x200 scaler normal 2x 15.2 fps

dosbox cpu 486_slow
quake 320x200 scaler none 16.2 fps
quake 320x200 scaler normal 2x 15.5 fps


i tested mdk with pentium_slow options the speed are exactly like qemu. and this is good

tested needfor speed, vrsoccer, dukenukem all are really good enjoyable.

i will check on debian PPC64 because on mate dosbox use 2 threads ... 2 cores :-O im courious there on debian

@samo79

i know, i had use the same core patch used from kas1e for his aos version

@kas1e

yesterday i parched doxbox svn with the diff on linux ppc. result no issue with the diff but when i try to select the core=dynamic doxbox reply me it swithced to auto because the option core was not available.
Did you make more implementation on the AOS sources extra diff for make it work??

thx

good job kas1e. i suggest in future to add the 3dfx module too. probably now with jit cpu you will have decent performance with it too.

@kas1e

in the quake command prompt, usually it exit with pressing in the game menù "tab" on the keyb.
timedemo demo1
and
timedemo demo2

the result will be show at the end of the demo on the command prompt

ps: when you run the command press fast the tab again or the command promt will be there and will meke the demo not run at real spead (because not all the scene will be rendered)

Kas1e https://www.vogons.org/viewtopic.php?f=32&t=65057&start=60

I think this was did in dosbox for Boxer. A dosbox modded version for MacOSx PPC leopard. If was it i confirm was much more faster than standard dosbox.

By the way Kas1e can be possible have the link with the original inculde for make i build it in a dosbox for lnx?
thanks

Guys,
is possible have the fimware upgrade file ?
It is not available any more on the blan/Genesys web site

@Hans

ok i understand now x5000 can be used in poles and not in italy ... is better warn user about "this machine need to work at home temperature not more hight then 28° celsious or you will face freeze if work in smp"

by the way, i ask aeon what kind of water cooling system can be compatible to p5040 because was my intention buy it ... and no reply.
when an object is in garancy and prize more than a motorbike im sorry but for me is normal ask the producer...


about issue with pc ...never in my life i see too much problems on a machine like i face on this one. i build my pc,my amiga, my macs from 1990 and the worst mobo never gave me this issues.

@RIBDEVIL

this issue come if you turn on first x5000 after the monitor.
start first the monitor wait a little bit and turn on x5000.

voltage drops ? umm on the devices if yes swap dvdrom on sata0 and hd on sata1 .... because this machine suffer of fpdma issue on atapi device if on sata1

the others i dont have solution ... just cry
