Re: The Quadra 800 coming to Qemu
qemu-system-ppc64 already emulates PowerPC G5 cpu.
qemu-system-ppc only emulates PowerPC G4 and below.

Re: The Quadra 800 coming to Qemu
Is Quadra 800 support even being developed on?
If you need more info, tell me
Re: The Quadra 800 coming to Qemu
Things move, but they move slowly:
https://github.com/mcayland/qemu/tree/q800-dev-mca
https://github.com/vivier/qemu-m68k
Current public status: start-up sound and grey screen.

Re: The Quadra 800 coming to Qemu
Any progress?
There's now an empty Qemu forum under the 68k emulation section (on this board) with no posts.

I guess you have to stay tuned to that forum .....

Re: The Quadra 800 coming to Qemu
That's what I get on Arm64 as a host system. Any progress in sight on this one?Current public status: start-up sound and grey screen
PS: The darn thing eats up an entire CPU core just sitting there (utilization 93%) - that is *abysmal* compared to B-II.
Is it supposed to be *that* bad?
Re: The Quadra 800 coming to Qemu
Hi,
You don't have a fully functional build?
I guess it depends on from which source you compile.
However, progress is immanent.
Some scsi stuff seems to be almost ready to be applied to master. Other patches can then follow. Audio issues will also be fixed.

Re: The Quadra 800 coming to Qemu
I got my qemu build from Debian bullseye and had to github the 68k module directly from the author's repo. It all compiled OK but as I wrote I only get a blank screen and a CPU core on the host side that is *completly* maxed out.
Given that I got to ask the question if this is even worth the wait for me, if I'm not running this on a supercharged Desktop Workstation?
I need a system that's comparable in speed to B-II, but w/o that baby's memory/sigsev issues.

Re: The Quadra 800 coming to Qemu
Yes,
That can be achieved by compiling from https://github.com/mcayland/qemu/tree/q800.upstream2.1
I'll move this topic to our qemu m68k forums. OOPS: no I won´t.

Re: The Quadra 800 coming to Qemu
Still compiling, had to bypass a lot(!) of w2errors.
Will the PPC emulation be as stable/fast as the 68k?

Re: The Quadra 800 coming to Qemu
make terminated with error 1 on rules.mak:89 (disas/arm-a64.0)
Looks to me like this thing could still use a good deal of tweaking.
Could it be that this thing is mainly meant to run on Intel/AMD host systems?

Re: The Quadra 800 coming to Qemu
I really have no idea whether it can be compiled on your host. Does qemu-system-ppc compile on your host?
In my experience the m68k emulation is way faster compared to the PPC emulation.
See here what it is currently capable of on an M1 Mac: https://www.youtube.com/watch?v=gLuo-2K798s

The Quadra runs Mac OS 7.1 to 8.1, A/UX 3.x and NetBSD. So I gather you ask whether the m68k emulation is as fast as the PPC emulation?Will the PPC emulation be as stable/fast as the 68k?

Re: The Quadra 800 coming to Qemu
The Qemu-PPC comes as a compiled binary from the official repo. But I have no clue how Mac conpatible it is and I got no PPC boot media anyway.
But most important: I don't want to loose precious time messing around with that unless I can get a system out of it that runs smooth, stable and is performant. I don't just want to get some screenshots to brag about, I want a system that is pleasant to work with.
If I can't get that and it turns out to be one of those "walking in quick sand" experiences then I'd rather not go there (lost too many days fiddling with B2 compile options already).

Re: The Quadra 800 coming to Qemu
Well I guess you then have to wait until the code gets into the official qemu repository through the review process and your distro provides a build.

Re: The Quadra 800 coming to Qemu
But can you answer my concerns regarding the PPC emulation part?
Re: The Quadra 800 coming to Qemu
In my opinion you can´t get a more stable PPC emulator than Qemu. It is not as quick as SheepShaver.
And it is not as fast as Qemu's upcoming m68k emulation.

Re: The Quadra 800 coming to Qemu
Thanks for all the hard work on this thing, but the wait is taking a toll. I just can't get passed the B-II SIGSEV issue on Arm64 and Arm-Qemu works out of the box for any platform but 68k.
Feels like getting cursed just because I turned away from WIntel.
Really everyone is still primarly developing for that platform - like the Tablet & Pi revolution never happened. :O
