Compiling qemu X64 for OS4.1 (Ryzen) and also other CPU (MAC)

It seems rude to me not to respond to:
@Balaton
@Maijestro
@smarkusg
@joerg

and all the other forum users who answer my questions.

So I'll try to ask a few questions whoever has the time and desire can answer them.
This is to avoid writing on other "posts" dedicated to other topics.
Because even if you don't want to, sometimes it's normal to write in other posts at first glance to participate in the topic.
So I hope my thoughts are right because I always have so many questions

Here I compiled with -Doptimization=3 without errors
but even modifying meson.build I get no errors.

./configure --target-list=ppc-softmmu --disable-dbus-display --enable-slirp --enable-lto --enable-sdl --enable-gtk -Doptimization=3

Result:

./configure --target-list=ppc-softmmu --disable-dbus-display --enable-slirp --enable-lto --enable-sdl --enable-gtk -Doptimization=3

OK,

If the log is long I can delete it.
But with this I would like to understand later, not now, if something is missing in the compilation for AmiCygnix, because I will come back to it later.

I was planning to buy a second ATI graphics card because I would like to do many things that I can't do now, always dedicated for OS 4.1.
But it seems that there are currently no suggestions on this.
To put up virtual systems but to do that I need a second graphics card in my specific.
A Geforce 1060 6gb can be found for 100 euros. But an ATI would be better if it is needed for qemu.

@white
Quote:There are no AmigaOS drivers for any NVIDIA gfx card. Except for some very ancient ones like Cirrus, Voodoo, etc. only Radeon R100/R200 (ATIRadeon.chip), Radeon HD and Radeon RX cards are supported.

AFAIK only a single user got a passed-through gfx card working with QEmu yet, see https://www.amigans.net/modules/newbb/ ... id=147757#forumpost147757
4 Radeon gfx cards tested:
HD4850, R9 270x and RX560/570 didn't work.
HD7000 does work (requires BBoot 0.7 or newer).

You need to use a separate IOMMU group for the passed-through gfx card. No big problem on Linux, but I don't know how/if at all that works on MacOS or Windows.

@joerg

this is interesting, thanks
I'll take a look now

@white
You don't get error with modifying meson.build and that works too until you want to update from git. Then you'd need to undo the change and redo it again afterwards so it's better to pass it to configure and not change meson.build. Maybe you can try to add one more configure option: --disable-qom-cast-debug but don't know if it makes any difference in performance. It may be a little faster in some cases but probably not a big deal, but if you want to optimise everything than this can be added.

With gfx card passed through to guest the AmigaOS driver gets full control of the card so a card is needed that QEMU can pass through correctly and AmigaOS can drive. This seems to be ATI HD7000 or similar card currently. Older cards aren't properly passed through by QEMU (it needs some changes in the places I've pointed to before) and newer cards may have problems with PCIe passed through as PCI or newer BIOS that crashes the emulated BIOS in these older firmwares or something. It also needs separate purchase of Enhancer software or whatever the RadeonHD driver comes with as the one included in AmigaOS 4.1FE is just enough to get picture to install the real driver that fully supports the card. One important point is that GPU pass through with pegasos2 needs BOTH -bios pegasos2.rom (but not -kernel bboot) and then boot with boot hd:0 bboot.fth with at least bboot 0.7. The firmware is needed to run the card bios and then BBoot is needed to fix IRQ routing and 64bit BARs. If you boot with -kernel bboot as usual then the card BIOS will not be run and may not work so need to boot with firmware and use bboot from firmware not on its own. It may be easier with amigaone where only the -bios u-boot-amigaone is needed without bboot or sam460ex but that may have other problems so currently only the pegasos2.rom+bboot way was tested.

I won't try to explain what's needed for AmiCygnix again as I did that for a few times so you'd need to understand the network setup under QEMU and either configure tap networking or with -netdev user add the appropriate hostfwd option to allow connecting to the X server in the guest. I'll let others have a go trying to explain that as I could not describe it in a way that you could understand so I would just confuse you further trying to explain.

@white
As for the card I would use the same one that @geennaam used.
On his screen you have the identifier 0x1002 x6810 = Curacao XT / Trinidad XT [Radeon R7 370 / R9 270X/370X].
That is, Radeon HD 7xxx - RX 5xxx 2GB . Most likely Club 3D Radeon HD 7870 Club3D S13 2GB GDDR5 1GHz

I also remember that I think @MartinW mentioned the motherboard requirements. It was more than half a year ago and I can't find this thread on the forum with this entry.

@smarkusg

Yes, I remember this discussion too, now I'll try to look it up

@balaton

Thanks, I will compile again with this other function you suggested.

It would just need something to further improve performance for the Ryzen in the qemu 3.xx version there were specific options for compiling for "Intel" I7 processors etc.
I still have the build files but I need to find them so I can show an example.

@Flash
he had given me some tips on this.

add this at configure or do an export.

@all

Thank you for your suggestion
Now I try.

I would also like to do some TESTS on optimization: 3 and native
how do I do them

I leave this link:
https://stackoverflow.com/questions/52 ... rch-native-used-so-rarely

How do I start this TEST ?
what options can I use in qemu to do the checks.
Thank you.

this is an example given from the link but I would like to do it on my CPU

Original with O3 not set and march=native.

800 out of 900 %89 time left: 0:0:0 time since: 4

what command can I run with qemu ?

@white

You could try running the tool that @Balaton made.
It was created for a slightly different purpose but maybe it will show you if your performance has increased.
QEMU script from Linux PPC under Pegasos 2 with lame.
Adapt the script to your needs ‘pegasos2-lame-test’ and see the results.

http://zero.eik.bme.hu/~balaton/qemu/amiga/pegasos2-lame-test.zip

@white
You could use http://os4depot.net/?function=showfil ... ty/benchmark/cpubench.lha on AmigaOS.
Results of that from different systems (real hardware, QEmu Mac ARM, QEmu and WinUAE Intel x64, QEmu AMD x64, QEmu Pi ARM, etc.) are available somewhere, but I currently find the link to it.

@joerg

unfortunately it is not reliable for testing I have always tried to use it but it does not serve my purpose.

@smarkusg


I can't get the script to work

tells me :
** Running test 1
./pegasos2-lame-test: 13: ./qemu-system-ppc: not found

How do I make it work


( However, everything seems faster )

@white

I have tested it briefly with optimization=2 and optimization=3 "-mtune=native -mcpu=nativethe" increased optimization level led mostly to problems with the graphics output it was so far everything ok, but behaved somewhat differently than with level 2.

I changed it directly in "meson.build"

With optimization=3 there was also no relevant speed increase.

I compiled with:



For me is always a good test with Quake1 Timedemo under AmigaOs4.1 and here I reached 29.2 FPS 1280x720 in both cases. So I'm not sure if optimization=3 does anything at all except maybe more problems.

The biggest problem is the lack of 3D acceleration everything else is already really
fast on my hardware.

@Maijestro

It's not a CPU speed issue
With Quake I do FPS 22.8 with 1280x800
With a basic 2048x1152 Desktop

I was interested to know if this compiled build had its advantages.
And for the moment it seems so.

I used to do a lot less.

@white

Quote:

Ok, I see then it has at least had an effect on your machine

@Maijestro
@all

Yes, I recorded Quake FPS 20.1 here
1280x800 and Desktop 2048x1152
because there is recording software.

https://youtu.be/_zUyGJbSQqM

but everything is faster E-UAE etc.

By the way I'm still using the old SDL
How can I see the versions of the SDL installed on my system from shell or otherwise ?

Which versions are recommended to install ?

Thank you.

@whiteQuote:

It doesn't matter which resolution you use for your guest system AmigaOs4.1 under the WB the result is always the same if you run e.g. Quake Timedemo in a slightly lower resolution which is then also used.

qemu 9 is also included AmigaOne ?
without needing to compile a separate branch ?

@white

Quote:

You can use Qemu 9 for all 3 machines Pegasos2/AmigaOneXe and Sam460. An extra branch is no longer necessary.

@Maijestro

Which one do you prefer from your tests ?
