Can anybody (Jocelyn ?) tell me the status and availability of the
powerpc system emulation?
I have been trying for a long time to run a powerpc kernel on a x86 machine.
A few years back I used psim but never got further than a ppc netbsd
kernel booting and crashing halfwaydown (linux kernel crashing too)
The problems. Understanding and making a working openfirmware devicetree
How to boot a kernel and putting it in the right space in memory.
How to get a working console and network.
Now I am trying to use the powerpc system emulation in Qemu to try to
run a powerpc linux in it but I am running into similar problems.
I found out there is not yet a powerpcbios and tried to use the
openfirmware image and linux kernel from my rs6000 ( a 7043-140 prep
machine running debian)
(IBM openfirmware for rs6000 machines can be downloaded at
http://techsupport.services.ibm.com/server/mdownload/download.html)
I tried changing the sources to get it to load and run the firmware or
linux kernel but didn't succeed.
I disabled running the vga bios because I thought that was one of the
problems but that didn't help.
> Current PPC system emulation status is: I can launch Linux and a
shell in it and use it. That's all.
Is there a way to get these patches so I can try this too or have you
already merged it with Fabrice's commits?
With a little luck some day Qemu should be able to run a linux kernel
and a complete partition dump of my rs6000 prep debianppc installation.
(This would include a working mac-on-linux ;-)
> For now, I use PREP, because my first goal is to eliminate PPC CPU
emulation bugs. As PREP is nearly a PC with a PPC CPU, I can re-use
current Qemu hardware emulation, which make things simpler... The only
thing I got for recent Mac emulation is OpenPIC (good start).
Good enough for me.
Greetings,
Martin
