[Qemu-devel] IBM makes AIX 6 beta available for download for everyone

[Qemu-devel] IBM makes AIX 6 beta available for download for everyone

[Martin]

IBM opened up a little bit and makes the beta of AIX 6 available to anyone.
Maybe this is an opportunity to get AIX running on QEMU.

At the moment QEMU does not yet understand the AIX cd boot format.
I tried to boot it using the -kernel option b
I tried to boot it in the following ways, but that doesn't work yet (as expected)
qemu-system-ppc -m prep -cdrom cd.AIX_6_OpenBeta.0723C1.V1.ISO -boot d

sudo mount -o loop cd.AIX_6_OpenBeta.0723C1.V1.ISO /mnt/loop
qemu-system-ppc -M prep  -kernel /mnt/loop/ppc/chrp/bootfile.exe

The -kernel option is meant for linux kernels but I hoped it would take an AIX kernel too.

You can download the AIX 6 beta from:

Hi,

AIX was already tested in QEMU and is not that it does not understand
the AIX boot format (it does!), just there is another problem that
prevents OHW from working (some say there is a regression in the IDE
controller code).

AIX 4.3.3 starts to boot (well, further than 5.1 & 5.2 do)

The serial console has:
-------------------------

--------------------

The graphic console has some messages (which I assume are the ones above) and then it goes blank.
It may still be doing something, I'll just wait for a while and see.

Both 5.1 and 5.2 complain about the return code from the ide controller 
ERROR: ATAPI READ12 : status 41 != 0x48

(ready | error ) != ( ready | drq)


It looks like open hack'ware is pretty much stalled, so its hard telling
what progress will be made futurewise.

Might it be possible to replace it with OpenBIOS?

Sure, and as both are GPL useful, code can be shared. But some PPC
developers are needed. It may still be easier to fix the OHW bugs than
start over anew.

I've talked about that idea long ago.

Theorically there should be no problem, as OpenBIOS already supports
PowerPC.

You'll have just to implement filesystems for HFS and booters for CHRP
and Mac OS (OHW has them).

Just compile OBIOS for PPC and try it :p

Not sure I understand... I thought Open Firmware was based on  
platform independent Forth code?
I'm running on ppc64 and could try to compile something under Linux  
in case that's the problem.


I had previously commented on ppc emulation issues but had not  
received any replies. I've not been able to do anything useful with  
the ppc emulation despite its status being "OK" on the qemu page.  
When I start it (compiled with the patch recently attached), using

qemu-system-ppc -boot d -cdrom debian-40r0-powerpc-netinst.iso

this is what I see on the console:

starting qemu...
init_ppc_proc: PVR 00080000 mask ffffffff => 00080000

The (Cocoa) screen then has some apparent debug information rushing  
by and an
ERROR: Give range: start 0x300000 0x100000
and unreadable chars before the Debian yaboot screen; looks and  
behaves okay from there.
If I type "install" or "install video=ofonly" it starts to do some  
things, intermixed with lots of these:
ERROR: Give range: [...]
HFS ERROR in hfs_get_bloc: Block 8192 not found
ERROR: bloc: -1 part size: 477144 5834a00
ERROR: OF_property_copy cannot get property 'device_type' for [...]
ERROR: overlap: start 0x1d00000 virt 0x2000000 end 0x2100000 0x[...]
ERROR: No range match !
ERROR: Give range: [...]

and it ends with

Calling quiesce ...
returning from prom_init

Some of the "funny output" does not appear if I use the -nographic  
option but the errors remain.

If I use qemu-system-ppc64 with the "install64" yaboot option it is  
shortened to this:

Please wait, loading kernel...
ERROR: Give range: start 0x1400000 0x600000
    Elf64 kernel loaded...
Loading ramdisk...
ERROR: Give range: start 0x1a00000 0x400000
ERROR: Give range: start 0x1e00000 0x400000
HFS ERROR in hfs_get_bloc: Block 8192 not found
ERROR: bloc: -1 part size: 477144 5834a00
ramdisk loaded at 01a00000, size: 4095 Kbytes
invalid/unsupported opcode: 1e - 12 - 1b (782106e4) 0x00000000014080e4 1

So no better. "install64" works fine on real hardware, thus the DVD  
image should be okay. Interestingly the fallback after quiesce, as  
seen in ppc emulation, occurs when trying 32-bit "install" on a real  
ppc64.


Questions: Do you get the same results? Or are those an OS X or an  
endianness issue? Which part is an OHW bug and which on the qemu side  
of things? Any workarounds or pointers to fix it?

The Sparc32/OpenBIOS combination has been working much better than  
this for me...

Yes, OF is basically a Forth-interpreter.
Of course this Forth-interpreter is in C and compile to machine code :p

Then you can add modules in F-Code machine independent code.

Try to compile OpenBIOS under Linux/PPC (using 32bit compiler, not
ppc64) and comment us.

Yes, that is obvious. Not so obvious was what ppc *developers* were  
needed for.
I got the other answer afterwards saying that HFS etc. support needed  
to be added.

I tried SVN HEAD of both fcode-utils and openbios-devel.

OpenBIOS supposedly has support for ppc and cross-ppc archs but that  
is not true. It currently only has support for cross-ppc (for the old  
PearPC emulator it seems). I copied these files as ppc_config.xml and  
ppc_rules.xml respectively to get the ppc target, in ppc_rules.xml  
changed the tool names to use the standard gcc etc. and was able to  
compile okay. Products based on this unmodified configuration were  
among others an openbios-pearpc.elf file - I thus changed ppc_rom.bin  
in some ppc files to this filename. Launching qemu-system-sparc -boot  
d -cdrom /dev/cdrom with a Debian Etch DVD inserted resulted in an  
opcode error. My guess thus is that this OpenBIOS file is not suited  
for qemu in that configuration?

Some observations that might be of interest:
- OpenBIOS has support for some (not all) PowerPC processors  
according to some Readme
- it specifically mentions ppc/AIX and has some apparent IBM  
contributions despite the missing ppc target
- the cross-ppc config mentions HFS and HFSP which I guess refer to  
HFS and HFS+ filesystems respectively (HFS was set to false, HFSP to  
true)

Maybe someone can shed some more light on what exactly needs to be  
changed config-wise or is missing in OpenBIOS or qemu in order to  
boot AIX 6 or any Linux.

[Blue Swirl]

The correct place for these questions would be the OpenBIOS list
(blatantly cross-posted).

Can't tell you much, but for sure, you won't need support for HFS or  
HFS+. HFS support enables you to boot all versions of classic Mac OS  
(1.0 to 9.2.2). HFS+ can be used for Mac OS 8.1 and later. Mac OS X  
can boot off HFS+ and off UFS. All PPC Macintosh OSs use an Apple  
partition map.

To install Debian I needed a minimum of three partitions: one "Apple"  
partition, one NewWorld bootloader partition (yaboot) and the  
standard ext3 root partition. No idea how the first two are structured.

I believe the point about HFS+ was that this would be required in  
order to replace OpenHackWare with OpenBIOS completely in the future.
