[Qemu-devel] PPC Haiku

[François Revol]

It seems the ppc OF loader for Haiku finally starts in OpenBIOS on qemu
:)

Though it currently stops here:
http://dev.haiku-os.org/browser/haiku/trunk/src/system/boot/platform/openfirmware/arch/ppc/mmu.cpp#L963

It seems OpenBIOS doesn't call the loader with translation turned on or
something alike. I thought OF specs required it, but it seems OpenBIOS
isn't alone there...
We will have to handle this case by creating the mappings ourselves it
seems...


For those interested in trying it, cf.

http://www.haiku-os.org/documents/dev/getting_linux_developer_tools
http://www.haiku-os.org/documents/dev/building_haiku_on_ubuntu_linux_step_by_step

You'd just use "ppc" instead of "x86" when running configure, with gcc4
since gcc2 is useless for ppc (just used for binary compatibility on
x86).

Then you can either build the full image:
jam -q haiku-image
which isn't bootable yet, or just go directly to the boot HFS/ISO:
jam -q haiku-boot-cd-ppc

I use then:

qemu-system-ppc -serial stdio -cdrom generated/haiku-boot-cd-ppc.iso -
boot d

OpenBIOS is running with enabled MMU and doesn't turn it off when it  
call the loader.

It seems there are pegasos and  OpenHackware workaround, did you try  
to remove them ?

Could you give me more details ?

Where can I download the ISO ?

Hmm ok so it's because it doesn't find it...

Is there a way to get the OpenBIOS console to serial ?
I tried -prom-env output-device=ttyb or ttya to no avail.
Also tried the OFW thing "com1 io"...

They are not triggered it seems:

Anyway here if what it prints:

1: empty region
total physical memory = 128 MB

With OpenBIOS r452 (two days old), you can simply use -nographic.

Ah nice, but it's not in qemu svn yet is it ? ;)

No, because the previous one (r450) is 9 days old and still nobody has
reported any bugs with it, so it must be perfect and there is no need
to update the image. ;-)

Can that one boot opensuse cds already? If not, feel free to take this  
as a bug report :)

I know Stefan worked on this, but I'm unsure what became of his patch.

openSUSE is booting well since openBIOS r448.

Almost but not completely perfect ;-)

Yes, openSUSE 11.1 boots ok.  No success with Fedora-11-Alpha, though:

  cd:0,\ppc\chrp\yaboot.conf: Unknown or corrupt filesystem
  Can't open config file

I still get a boot: prompt, but there are no images to boot.  Same problem
occurs with F10.  Is there any workaround?

This is with the image

OK, I try to make it working.

Fedora-10 boot CD is now working with openBIOS r456.

To boot, use following command:

boot cd: conf=cd:,\ppc\ppc32\yaboot.conf

Fedora-11 is also working, but kernel hangs somewhere...
