If you are on a macOS M(Series) host and you want to run Linux in the hypervisor here is the basic commands with VGA networking and sound support. Some reason I could not get CoreAudio up, but SDL works great for sound.

This is an ultra fast way to run Linux adjust to fit your needs. If people ...

Thanks, I think that's it!

I've noticed an impressive speed/performance boost in my Mac OS 10.4.11 Qemu VM :shock: :mrgreen: Any chance to get a dual-core build but with sound support too?

Andrew_R has patched screamer with SMP, but I think we need to have someone branch Qemu on Github so we can continue with this ...

Now I'm working on making it cross platform for arch ppc/aarch64/x86 using SSE2 and NEON as well as VSX/VMX.

A new experimental build enabling dual cpu support has been added to the second post in this thread.

Kind of a moot point anyway, as the graphics stack is hopelessly broken in PPC Big Endian upstream anyways, but runs just fine with PPC Little Endian. So if folks want to run PPC linux they can just use the pSeries machine in qemu-system-ppc64.

Well, older Linuxes also exist, at Debian ...

I figured I start a thread to monitor enhancements in Qemu SMP and see what we can do to speed up the FPU and AltiVec units over time.

Here is a link to a cross platform AltiVec benchmark we wrote so we can see how AltiVec benchmarks between Linux and Mac OS X.

SMP should work with 2 CPUs as far back as 10.2; before that, I have no idea.

I saw your comments regarding OS 9 and the 2nd CPU issues; could it be something to do with the different ways that OF is managing the hardware between OS 9 and OS X? Something OS 9 isn't checking? If so, could we ...

Wow, that's great! How long until this gets into one of the unified experimental builds (multiple displays, screamer, etc.)?

Hopefully Cat7 can work us up an experimental build with SMP.

For now OS 9 is a no go for SMP, but I'm still working on it and have some idea what is casing the system ...

If 2 is good, 4 is better!
