[PATCH 2.6.10-rc3][PPC32] Fix Motorola PReP (PowerstackII Utah) PCI IRQ map

[Tom Rini]

The PCI IRQ map for the old Motorola PowerStackII (Utah) boards was
incorrect, but this breakage wasn't exposed until 2.5, and finally fixed
until recently by Sebastian Heutling <sheutlin@gmx.de>.

Heh. I take that back. The whitespace "corruption" was in the file itself. 
Seems to have spaces instead of tabs there..

Yesterday I finally got around to testing it. It seems the patch has 
been applied in Linus's tree so I downloaded the latest BK and tried it.

Still does not work for me but this time it's different. Before the 
patch SCSI worked fine but PCI NICs caused hangs. Now I can't test PCI 
NICs because even the onboard 53c825 SCSI hangs - seems it gets no 
interrupts.

It detects the HBA, tries device discovery, gets a timeout, ABORT, 
timeout, TARGET RESET, timeout, BUS RESET, timeout, HOST RESET and there 
it hangs.

Does it work for anyone else on Powerstack II Pro4000 (Utah)?

It does work in 2.6.8 using backported patches (e.g. the debian 2.6.8 
kernel). But it doesn't work above that version because of other patches 
in arch/ppc/platforms/prep_pci.c and arch/ppc/platforms/prep_setup.c 
(made by Tom Rini?). I couldn't find out what exactly is causing this 
problem yet (because lack of time and the fact that my Powerstack is 
used as a router).

Ah, this could well be my fault.  Those patches were to improve support
of IBM RS/6000 PReP boxes.  Do those machines have residual data?  If
so, could anyone who has one send me the contents of /proc/residual?

Also, a full boot log when working and failing would be cool.

it does not really hang, it just tries to initialize every target of the
HBA (here: from sym0:0:0: to sym0:15:0, see [1] for more info) and it is
so busy with it that the bootprocess seems to hang. after failing with the
last target, booting continues just fine. (i have no disks attached,
booting via nfsroot)

[1] it's all here: http://nerdbynature.de/bits/hal/2.6.11-rc3/

(yes, they are from different dates, but the setup is the same. the
kernelversion from messages is 2.6.11-rc2, the rest is all 2.6.11-rc3,
from vanilla (-BK) sources)

No, the PowerstackII Pro4000 (Utah) has no residual. I couldn't see 
anything unusal in the bootlogs except that
neither IDE nor SCSI interrupts occour (timeouts for SCSI and lost 
interrupts for IDE). I assume other PCI-devices have a similar problem. 
I will try to extract some bootlogs in the next days but I think they 
won't help.

Can you try : 

  http://people.debian.org/~luther/d-i/images/daily/powerpc/netboot/vmlinuz-prep.initrd

It works for me, and the kernel (2.6.8) has the irqs patched, but not the scsi
stuff touched, i think.

Oh, damn, need to fix my daily builder, should be ok for tomorrow. IN the
meanwhile, you can try : 

  http://people.debian.org/~luther/d-i/images/2005-02-23/powerpc/netboot/vmlinuz-prep.initrd

This is a zImage.prep kernel with builtin initrd, you just put it somewhere

This seems to work fine: onboard scsi is OK, pci nic with de4x5 is OK 
too. Haven't got more PCI cards in there currently.

Ok, can you now install the 2.6.10-3 package from : 

  http://people.debian.org/~luther/powerpc/2.6.10-3 

(you need kernel-image-2.6.10-powerpc and mkvmlinuz), call mkvmlinuz on it (or
add it to kernel-img.conf as postinst_hook=/usr/sbin/mkvmlinuz).

You may probably want also to modify /etc/mkinitrd/mkinitrd:MODULES_DEP to dep
instead of MOST, or you may hit size problems with your initrd, i would be
interested in knowing that.

Then just dd your /boot/vmlinuz-2.6.10-powerpc to your prep partition, or
better yet to a tftp server, and try it out. If the scsi problems are there,
can you fill a bug report against kernel-source-2.6.10 ? 

Friendly,

Thanks for the new kernel. Just filed a bug report on 
kernel-source-2.6.10.

It worked without changing the module list, with 5.2M resulting vmlinuz.

oh, what fun - it's booting! de4x5 is loading (although i build my kernels
with a (compiled in) tulip driver). sym53c8xx gets loaded and initializing
the scsi bus is *not* blocking all other activities as usual.

here are the logs:

So, now, we need to find out what the problems where, i think it is something
that went in between 2.6.8 and 2.6.10, and leigh said he had some ideas. Leigh
can you elaborate on those ?

may i ask what patches were applied to a vanilla 2.6.8 kernel to build the
2.6.8-d-i then?

yes, the prep_pci.c and its irq-mappings. the PowerStackII lines were 
changed back and forth, and a current 2.6-BK is only different in one 
line to the patch you mentioned:

http://nerdbynature.de/bits/hal/2.6.11-rc5.patched/powerpc-prep-powerstack-irq_2.6.11-rc5.patch

unfortunately it did not help either and i'll switch back to vanilla
