[Qemu-devel] Here is a patch to build qemu with powerpc (system) support on win32

[Martin]

[-- Attachment #1: Type: text/plain, Size: 1184 bytes --]

I mad a little patch to be able to enable powerpc system emulation on 
windows
The patch is against qemu 0.5.5.
Just run configure with
./configure --target-list=i386-softmmu ppc-softmmu
(Which is the default with this patch)
and it builds both qemu.exe (which is i386 system emulation) and 
qemu-system-ppc.exe (which is ppc system emulation)

I tested it with the VGA framebuffer enabled linux kernel zIamge and the 
debian install disk on  Jocelyns page
http://jocelyn.mayer.free.fr/qemu-ppc/

It seems to work for me.
I used the commandline:
qemu-system-ppc.exe --kernel zImage_vgafb.prep --fda 
debian_install_root.bin --boot a
and it just boots.

If anyone is interested I can make my binary qemu-system-ppc.exe 
available but I think it would be better to place one on the Fabrices 
qemu homepage or on Jocelyns qemu-ppc homepage if it is ready for primetime

Strange thing about the patch is I had to manually set the env struct to 
zero in cpu_ppc_init (in translate.c)
for(i=0;i<sizeof(CPUPPCState);i++)
{
    ((char*) env)[i]=0;
}

With the standard
memset(env, 0, sizeof(CPUPPCState));
The compiler complained about not being able to free a register.
 
Greetings,
Martin

Has anybody been able to run MacOnLinux inside qemu's ppc emulation?

;)

If so, this development could be very interesting...

I am surprised to hear that ppc system works on Windows.
It works fine on my PC. I can see ash prompt.

If you could run it inside qemu, you could run MacOSX (on MOL on linux on
qemu emulating a ppc) on i386.  Or under any host qemu supports.

I thought that doesn't work right now, does it?  But it would be cleaner,
you're right.

[Qemu-devel] pearpc (PPC) anyone?

[Johannes Schindelin]

Hi,

Today I saw for the first time the project pearpc:

http://pearpc.sourceforge.net/

It emulates a PPC machine with JIT. Has anybody seen/worked with it
before? How does pearpc relate to qemu? Would a cooperation be good?

Ciao,

[Qemu-devel] Mac OS X installer working

[Jamie Burns]

Has anybody else seen this project:

http://pearpc.sourceforge.net/screenshots.html

They appear to have the Mac OS X installer working. Is there possibly code
that could accelerate getting Mac OS X on QEMU working?

Yep, they support 3C90x which is imho better than ne2k currently supported
by Qemu, so maybe Qemu authors could "steal" some code from it.

I spoke too soon!

  I just found this:

PPC emulator with JITC for PCs.

http://pearpc.sourceforge.net/screenshots.html

Initial report (not mine) says that this lets you run OS X on a PC 
faster than on a comparably equipped mac.

They don't appear to be using code from qemu, but from Bochs.  The code 
appears to be GPL, perhaps some useful code could be found from here to 
help the qemu PPC project?

I am looking at the code. I'll see if it is possible to use it to have a 
Mac OS X support in QEMU.

doesn't MacOS X starting with X.3 (Panther)
require AltiVec support (G4) to run?

if that is complete bullshit, please ignore ;)

Wrong. It runs on g3, and g3 hasn't altivec.

I might be wrong here, but from what I've heard Apple made an effort to make 
10.3 run better without AltiVec. Previous versions of OSX has been very well 
optimised for AltiVec and the G4 which didn't make G3 users very happy.
