Here is the lists of operating systems that I'm able and not able to run on QEMU PPC:
- DEBIAN 5.0.5 PPC it works - OPENSUSE 11.1 PPC it works
- FreeBSD 8.1 PPC hangs (see below details) - NETBSD 5.0.2 PPC and PPC64 does not load with defaults (see below details) - SLES 11 SP1 PPC does not load with defaults (see below details) - AIX 4.3.3, 5.1 and 6.1 do not load (see below details)
Some time ago I remember that the "working" OSs was more that now :-(

Oh this is very interesting. Could you re-post with the full qemu command lines for each OS for other people to replicate? Also, if things do get further with revisions before r828, could you indicate these too so we can see which ones of these are indeed regressions?
Many thanks,
Mark.
qemu commands are very simple and basic:
qemu-system-ppc -k it -m 1024 -boot d -hda disk.qcow2 -cdrom cdrom.iso
or
qemu-system-ppc64 -k it -m 1024 -boot d -hda disk.qcow2 -cdrom cdrom.iso
This evening I will post the test for OSs with old (r828) revision of openbios inside qemu. Ciao

Great - thanks for helping with this!

Sorry to make, maybe, some confusions in the previous posts. I try now to make clear situation about my test data.

I hope this info help someone to understand the ppc "caos" in openbios code or qemu code :-)

Great :)
- FreeBSD 8.1 PPC => hangs at "Kernel entry at 0x100100 ..."
This may be the same issue that Blue sees with SPARC to do with ofmem allocating memory from the same region that the kernel tries to use.
- NETBSD 5.0.2 (netbsd-ofppccd-5.0.2.iso) PPC => hangs in the OpenBios
console wuith message "Trying cd:,\:tbxi..."
- AIX 4.3.3 PPC, AIX 5.1 PPC, AIX 6.1 PPC => hangs in the OpenBios
console wuith message "Trying cd:,\:tbxi..."
These two appear to be triggering some kind of bug in the filesystem code related to finding system executable files from the CD image. Do these images contain HFS filesystems or other? If you let me know which, I can point you towards the files you need to look at.
- NETBSD 5.0.2 (netbsd-prepcd-5.0.2.iso) PPC => waiting in the OpenBios
console after message "No valid state has been set by load or init-program"
- SLES 11 SP1 PPC => waiting in the OpenBios console after message "No
valid state has been set by load or init-program"
See my previous email to Andreas - these mean that either the load failed, or init-program failed to detect a valid ELF header after the load took place.
I hope this info help someone to understand the ppc "caos" in openbios code or qemu code :-)
It's really great to have someone interested in looking at the various outstanding PPC issues. Given that you can build OpenBIOS from SVN, all you need is a cross-gdb and you're good to go - I'm happy to point you towards the relevant sections of code. I don't think the fixes should be too complicated either.
ATB,
Mark.
