I just put a 'if (!l3) return 0;' into cache_grow, the backtrace is the
one from the initial report.
Reverting 04231b3002ac53f8a64a7bd142fde3fa4b6808c6 does not change
anything.
Since -mm boots further, what patch should I try?
The kernel boots on a different p570.
See attached dmesg. huckleberry boots, cranberry crashes.

* Re: ml310 kernel2.6 booting problems
From: Joachim Meyer @ 2008-01-17 20:19 UTC (permalink / raw)
To: Grant Likely; +Cc: linuxppc-embedded
Hi
My Linux runs finally. Thx again for the help.
But 3 Questions remain:
1. After mounting the rootfs there came an message,
"fatal error, couldn't find modprobe in /lib/modules/2.6.24-rc3/..." or something like that.
so I changed the folder /lib/modules/2.6.19.2 to /lib/modules/2.6.24-rc3.
Is this a solution or will I get Problems with this?
Can I say ELDK that I have Kernel 2.6.24.rc3 ?
I only installed and ran the 2 scripts, like they say in the docs.
2. There came also something, that the it couldn't read the time or clock. Is it an error
or has the Board no clock?
3. I still need a network connection. Because of some special reasons
I prefer the ml310, so changing to a XUP would be the last possible solution.
Because of the Problems I had when I tried to compile the 2.4-kernel
(where the pci bridge works, I think) and can't find the proper 2.4 kernel-Version
to compile it successfully, theres only one solution, beside the XUP, left.
I need to bring up the pci bridge for the ml310.
I read at the mailing list this:
-----------------------------------------------------------------------------
I ended up using Secret Lab's GIT tree as my source archive, so I'll
let you know if I need to fix some code.

Hmmm... I'm not really ready to invest that much time into the PCI for ML-310.
--------------------------------------------------------------------------------
http://ozlabs.org/pipermail/linuxppc-embedded/2007-December/029211.html
How much work would it be (approximated), and do you think I can success (I'm a novice, like you know)?
Would you help me (Tell me where to start & what to do)?
Anyway I ,once more, wanna thank you, I wouldn't come so far, in that time without your help.

* Warp Watchdog
From: Sean MacLennan @ 2008-01-17 20:23 UTC (permalink / raw)
To: linuxppc-dev
The taco, er warp, has a watchdog timer built into the fpga. The
watchdog is very trivial and very tied to the warp. I have put it has
part of the platform code rather than a standalone module.
Two reasons for this: one, once started it can't be stopped. A module
unload would be fatal ;) Two, it is so closely tied to the taco that it
really has no use otherwise.
The platform always starts the watchdog, assuming you asked for the
watchdog, but does not enable it until hit from user mode.
What is the general feeling about this implementation? I am not
submitting this for inclusion in the kernel right now, just feeling out
what others think.
Cheers,
Sean

Sorry for the delayed reply. I've gone with "wrs,epld-localbus" based on
the format of all the existing localbus entries.

OK, I think I've captured the intent of what you mean here. It makes
the dts appear a lot more complex to a non-dts person (IMHO), but it
does capture the full details of the board this way.
I've put in a 2 address cell localbus entry, put in all the devices
listed in TFM for each CS#, of which the EPLD is on CS5, and since
the EPLD sub-decodes off of CS5, it too is a bus with 2 address cells
and the equivalent of a CS# for each sub-device. It takes a bit to get
your head around the various ranges = <...> with varying #s of parameters
(or at least it did for me) but I think I have it mapped out properly.
The UARTs still work, and since they are out in the weeds now, some three
nodes deep, it has to be at least partially correct...
[All the good stuff with the localbus is near the bottom of the dts.]
Paul.

* Problems with PCI on 8280
From: Rune Torgersen @ 2008-01-17 21:33 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 3108 bytes --]
Hi.
We have e 8280 bioard with PCI. We have three memory ranges set up;
0x8000_0000 to 0x8fff_ffff is prefetchable memory
0x9000_0000 to 0x97ff_ffff is non-prefetchable memory
0x9800_0000 to 0x9800_ffff is IO.
our device tree has
ranges = <42000000 0 80000000 80000000 0 10000000 // Pre-fetch memory
02000000 0 90000000 90000000 0 08000000 // Normal Memory
01000000 0 98000000 98000000 0 00010000>; // I/O
for the memory ranges in the PCI node (full node at the end)
Our problem is that we can only access the first 128MB of the prefetchable area.
an access to 0x87ff_ffff works (after ioremap), while an access to 0x8800_0000 causes an bus error.
trying to access 0x87FFFFFC -> 0x00000000
trying to access 0x88000000 ->Machine check in kernel mode.
Caused by (from SRR1=49030): Transfer error ack signal
It is like the prefetch area is not set up correctly for ioremap.
The PCI registers are set up correctly in u-boot, and we can access the whole prefetch area in u-boot without any problems.

Crap, I thought I fixed that one, but the patch never made it out...
I'll fix that tomorrow, sorry about that.

Are you using cuImage, or a regular uImage with a device-tree-aware
u-boot? If the former, try commenting out the call to fixup_pci() in
arch/powerpc/boot/cuboot-pq2.c and let me know if that changes anything.
Otherwise, are you sure the kernel didn't move BARs around such that
there's no longer a PCI device mapped at 0x88000000 (or that the device
that is there has been disabled)?
Can you show the contents of the following big endian registers:
TESCR1 (0x10040), TESCR2 (0x10044), PCIBRx (0x101ac, 0x101b0), and
PCIMSKx (0x101c4, 0x101c8)
and the following little endian registers:
POTARx (0x10800, 0x10818, 0x10830), POBARx (0x10808, 0x10820, 0x10838),
POCMRx (0x10810, 0x10828, 0x10840), POESR (0x10084), PCI_EACR (0x10890),
and PCI_ECCR (0x108a0)
after the machine check happens?

Have a look at this and see if it seems OK to you. It collapses the soc,
tsi-bridge, opb and localbus code blocks into one. The patch is layered
on my previous patch that did the for_each cleanup on the np's but if folks
are OK with the general implementation, I'll spin an equivalent patch
for direct application to the origin/for-2.6.25 branch with signed off etc.
Thanks,
Paul.

That's true, defconfigs are only reference configurations, but still,
I would opt for a separate defconfigs as it is more clear which target
given defconfig is meant for and it is more convenient for development
and customer to have it separate. And IMHO it's actually easier to
maintain, as you don't need to consider all three boards each time you
update defconfig and don't need to test each defconfig change on three
(right now) boards, etc.

I've seen this kind of behavior. i may guess that you configure the kernel
with PREEMPT, assuming it will solve the problem for you.
I'll split the problem into two:
1. program loading stage is finished (+ reschedule)
2. thread execution time (delay)
when executing a new application it's involved with plenty of kernel
activity such as fetching the application from storage, loader
relocation,allocating and remapping pages, resolving dynamic linking etc...,
all the activity occurs under the hood of the kernel, suspending most of the
kernel activities, due to many spin locks on the way. that delays other
kernel threads as well, and even workqueues.
trying to bypass the symptom - re-running the exact external application ,
should not be involved with a second delay, as it was cached. so may be
running the external application in advance may be good enough for you.
what you actually need is a better kernel preemption such as using Ingo
Molnar 's PREEMPT_RT patch. (it may reduce performance a little).
the second part is that the scheduler delays the thread execution as it
think other kernel's entities has a higher priority such as softirqs,
workqueue, etc...
the PREEMPT_RT may solve this problem as well as it bring a better priority
control, with the addition of priority inheritance.

From: Mariusz Kozlowski @ 2008-01-17 22:15 UTC (permalink / raw)
To: Andrew Morton; +Cc: linuxppc-dev, paulus, linux-kernel
In-Reply-To: <20080117023514.9df393cf.akpm@linux-foundation.org>
Hello,
The script below kills powerpc. oopses get longer and more
wonderful with every next 'cated' file.
/proc/<pid>/task/<pid>/pagemap seems to be the cause of oops. The
important thing is that it oopses for random (that is not first in a row)
process from /proc. So not every 'cat /proc/<pid>/task/<pid>/pagemap'
causes an oops.
I could try to bisect this but this powerpc box is iMac G3 (cpu at 400MHz)
and this will take time. So any hints appreciated.
Regards,
Mariusz

This makes the setjmp/longjmp code used by xmon, generically available
to other code. It also removes the requirement for debugger hooks to
be only called on 0x300 (data storage) exception.

Jocke,
I ran across this patch doing some looking around. It isn't in the =

downloaded a while ago and have been working with, and I am not sure of =
the
real extents of its support.
Maybe Kim or Kumar can fill us in, on if it is what we are looking for.

In any regards, it definitely looks like something we should be checking

Why not?

I believe so... other than the sources, of course. :-)

* L3CR
From: linuxppcdev @ 2008-01-17 22:26 UTC (permalink / raw)
To: Linuxppc-dev
It there a l3cr parameter? It's not in the kernel documentation. I'm
trying to enable L2 and L3 cache on a G4 cpu upgrade board in a powermac.
>From OSX I was able to get the values of:
l2cr = 0x80000000
and
l3cr = 0x9F020300
from a cache config utility. I've seen references to l3cr setting on
bsd lists but not for linux.
Thanks...

This board is also resold by Freescale under the names
"QUICCStart MPC8248 Evaluation System" and "CWH-PPC-8248N-VE".
Signed-off-by: Scott Wood <scottwood@freescale.com>

Removed const/initdata combo, and used simple-bus for probing.
Please apply for 2.6.25.
