What the fastest possible x64 emulation way of OS4 today ?

@Maijestro

I immediately wanted to test your precious suggestion. for (AHI)

I have to make myself want to move the entire system to SSD

With WinUAE the speed increases exponentially and the "cache" of the SSD is not exploited.

I don't know if with "qemu" the SSD disk cache is exploited.
We should understand if the partition initialization can occur as on "real hardware"

In any case, the speed increases at least ten times in writing and also in reading even without "cache"

a bit like what happens on old laptops when you put the SSD in place of the mechanical HD.

I don't know, in this case with qemu it would be useful to have an opinion from @balaton.

@whiteQuote:

Somewhere here in this forum I had already tested write and read accesses @joerg gave me the hint and it was much faster than on real hardware.

AmigaOs4.1 is here with me also on a very fast SSD transfer rates:

@Maijestro

but does the test concern a virtual HD on SSD or on a dedicated real SSD partition ?

@whiteQuote:

Of course I installed AmigaOs4.1 on a Virtual HD, have you found a way to use AmigaOs4.1 on a real HD under Qemu?

If that's the case, I'll have to completely change my setup.

@Maijestro

the preparation happens in this way
"x76" raw disk
in this case there is no need for the "hide" flag
or is it better to say yes I don't remember with Linux

with windows yes, because otherwise it always tries to initialize it and it cannot be used

you can optionally set the "hide" flag

sudo fdisk -l

Device Boot Start End Sectors Size Id Type
/dev/sdd5 1892083712 1948473343 56389632 26.9G 76 unknown <<<--- this is my real partition on HD that I currently use with WinUAE

as you can see it is marked as "76 and unknown"
because it has the SFS filesystem of AmigaOS Classic


initializing with qemu with the Pegasos2 CD
-cdrom Amiga.iso -hda /dev/sdd5/id/ etc.

now the question is:
Is it accessible with qemu ?

I might already test this just to see if the AmigaOS CD-ROM can access it.

If he accesses it, it's done.

The process can work.

Once everything is complete.
the nice thing is that "true-image" is able to backup the entire partition in bulk despite being an AmigaOS partition

so when you back up you can include it in addition to your main system.

I backed up Linux two days ago because I wanted to.

Ok, it works

by booting from the Pegasos2 CD

I have direct access to the hard disk where AmigaOS Classic is installed and if I wanted I could initialize it to see if everything works.

here is the simple command:

sudo qemu-system-ppc -L pc-bios -M pegasos2 -bios /home/white/Downloads/pegasos2.rom -m 1024 -serial stdio -vga none -device sm501 -device rtl8139,netdev=network00 -netdev user,id =network00 -cdrom /home/white/Downloads/Pegasos2InstallCD-53.54.iso -hda /dev/sdd5

is the log:

I'll make a video now

Of course now it's a matter of understanding as well as being helped

I used the pegasos.rom in this case.

So I guess it can be done
here the video:
https://youtu.be/9PHDSppyqn8

therefore a more complete command would be needed for the part dedicated to the real partition

does anyone know how to do it ?

@white

Elude is a group from the AmigaOS scene from my country ... must work on my hardware
They were always unlucky to come second from what I remember....

It works although sometimes you have to wait a while.

@smarkusg

Well,

Can you post or attach your config file somewhere ?
Thank you.

Maybe it's a management problem
chipmem_size or z3mem that I assigned

which picasso driver (uaegfx) did you use (version) ?

I would prefer the complete config file if possible

For the real hard disk
it also works:

Now I'd like to find a way to not use the ROOT command to start qemu

and I imagine that:

WARNING: Image format was not specified for '/dev/sda5' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.


And
-hda/dev/sda5

needs additional parameters
but I can't find them

some idea ?

@all

Can someone please link to the AmigaOne Qemu emulation?

I have searched the whole forum but can't find this thread anymore. There was some debug information I did under this emulation and I need this information now to improve the sound output.

@Maijestro

https://www.amigans.net/modules/newbb/viewtopic.php?topic_id=9282

@Primax

Thanks for the quick help

Well it seems everything is ok,
the SSD is recognized and is ready to be initialized.

The difficulty I encountered was the "hidden" flag.
Having both Linux and Windows, if I did all the work from Linux then when I went to initialize the SSD from AmigaOS I had the RDB-DISK with the wrong blocks.
Because strangely, an uninitialized partition appeared in Windows 10.

Long story short I solved it.
Those who only use Linux will not encounter this problem.

But if you have both Linux and Windows you may encounter this problem.
(Although I use Split Boot-Loader it is not dual-boot for practical reasons.)

For MAC there probably won't be this problem.
But I can't say because I don't have a MAC

Clearly the SSD will not be able to use the "cache"
But I think the speed of execution improves.

I just have to try now.

The command line:

sudo qemu-system-ppc -M pegasos2 -accel tcg -kernel /home/white/Scaricati/bboot-0.4/bboot -initrd /home/white/Scaricati/Kickstart.zip -m 2048 -serial stdio -device sm501 -cdrom /home/white/Scaricati/Pegasos2InstallCD-53.54.iso -hda /dev/sdc2 -netdev user,id=mynet0 -device rtl8139,netdev=mynet0 -display gtk,zoom-to-fit=on -full-screen -vga none


First I'll back up with TrueImage but I don't want to do it all over again

here The SSD recognized without problems

Thank goodness I watched the video again
I was initializing the 1TB SSD

@whiteQuote:

To be able to use a real SSD under Qemu for AmigaOs4.1 would of course be ideal, but mounting under MacOs with -hda /path/to/SSD/ doesn't work without further ado, I need to read up a bit more on how things work under MacOs with Qemu.

@Maijestro

I'll try it now and let you know if it's worth it
I hadn't used Linux in years.
I dedicated 50gb for AmigaOS
On the other hand, I bought the 250GB SSD specifically to use qemu

https://youtu.be/AJEoERNQZ5c


note:
the right command would be:
-hda /dev/sdc2/ "disk id"
precisely to avoid unexpected device changes

but I couldn't find the syntax to do it

@whiteQuote:

This looks really good, I keep my fingers crossed that it works and am curious about further tests.

The read and write speeds of the virtual HD are already enormously high, I'm not sure if passing a real hard drive will be even faster, or even relieve the CPU a bit.

Would this also allow such a device (SSD or another) to be used to be accessed from both "sides" - the host system and AOS4.1?

SDD works.

this problem also remains:
even if AmigaOS works and the SSD works:

WARNING: Image format was not specified for '/dev/sdd2' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.

I also tried with pegasos.rom
instead of boot-0.4 but the problem is identical.

I was reading a bit of everything online.
But I can't find the solution.

Hoped @balaton can give me some suggestions or anyone might know how to do it.

1)Everything works, ssd etc.
2)I can also access the WinUAE partition on the OS4.1 Classic system. Clearly I can't use the apps.
3)I can use SSD + a .raw virtual disk at the same time
just add it with "HDToolBox".
4) I use a 250gb SSD from "crucial" which does not perform excellently.
paid 27 euros on Amazon. But it's good for its price.

Now let's get to the problem

This also occurs with a normal configuration:

so if I use the .raw disk configuration

example:
qemu-system-ppc -M pegasos2 -cpu 750cxe -accel tcg -kernel /home/white/Downloads/bboot-0.4/bboot -initrd /home/white/Downloads/Kickstart.zip -m 2048 -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 -netdev user,id=mynet0 -device rtl8139 ,netdev=mynet0 -drive if=none,id=hd1,file=/home/white/Scaricati/coffin.raw,format=raw -device ide-hd,drive=hd1,bus=ide.1 -display gtk,zoom -to-fit=on -full-screen -vga none

Everything works.

But if I do

sudo qemu-system-ppc -M pegasos2 -cpu 750cxe -accel tcg -kernel /home/white/Downloads/bboot-0.4/bboot -initrd /home/white/Downloads/Kickstart.zip -m 2048 -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 -netdev user,id=mynet0 -device rtl8139,netdev=mynet0 -drive if=none,id=hd1,file=/home/white/Scaricati/coffin.raw,format=raw -device ide-hd,drive=hd1,bus=ide.1 -display gtk, zoom-to-fit=on -full-screen -vga none

then using : sudo qemu-system-ppc etc. etc.

the audio stops working
Here are the errors in the output window:


ALSA lib pcm_dsnoop.c:566:(snd_pcm_dsnoop_open) unable to open slave
alsa: Could not initialize ADC
alsa: Failed to open `default':
alsa: Reason: No such file or directory
ALSA lib pcm_dsnoop.c:566:(snd_pcm_dsnoop_open) unable to open slave
alsa: Could not initialize ADC
alsa: Failed to open `default':
alsa: Reason: No such file or directory
audio: Could not create a backend for voice `ac97.mc'

you can try it yourself

use in front of your current command:
I sweat
and the audio should stop working.

I guess I have to compile differently and add my "user" probably.

I also simply tried:
./configure --target-list=ppc-softmmu --disable-dbus-display --enable-slirp --enable-lto --enable-sdl --enable-gtk --audio-drv-list=alsa,pa

but it's the same.

with the SSD if I do:

sudo qemu-system-ppc -M pegasos2 -cpu 7457 -accel tcg -kernel /home/white/Downloads/bboot-0.4/bboot -initrd /home/white/Downloads/Kickstart.zip -m 2048 -serial stdio -device sm501 -netdev user,id=mynet0 -device rtl8139,netdev=mynet0 -vga none -hda /dev/sdd2 -audiodev driver=alsa,id=snd0,out.try-poll=off -device AC97,audiodev=snd0

it's the same the audio is not heard.

Practically :
IF YOU COULD USE THE ABOVE COMMAND WITHOUT "sudo" EVERYTHING WOULD WORK

How do I compile to enable the "white" user
to use the SSD without the "sudo" command?

or I can somehow modify:
qemu.conf

somehow like:

#user=root
#group=root

in

user=white
group=root

with libvirt
I have already created the "white" user
etc. but I imagine it has nothing to do with qemu from the command line.

@Reth
What do you mean by:
Would this also allow such a device (SSD or another) to be used to be accessed from both "sides" - the host system and AOS4.1?

If you give me a practical example I will understand better

this removes the restrictions:

WARNING: Image format was not specified for '/dev/sdd2' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.


-drive format=raw,file=/dev/sdd2

now there is no more warning

the audio problem remains


I always sudo fdisk -l
at every startup
(of the machine Linux not of qemu)

the DISK ID should also be added here
because it could change with each reboot.

And you might mount the wrong partition

I haven't figured out how to add it yet
