So that's in arch/powerpc/sysdev/uic.c.

Well, I myself have no idea. It could also indicate a bug in the uic code.
But let's CC some people responsible for this code. Pekka recently added
this WARN that triggers in your case; David and Paul look to be the
people most involved in the uic code.
Start of the thread is at http://lkml.org/lkml/2009/6/20/165.
Cheers,

It's not implausible that this is, in fact, the first bad commit. The
early slab topic could easily have been correct for everything in the tree
when it was written, but cause problems with some other patch developed
simultaneously.
It's worth rechecking that both 871fa90 and b8ec757 are good and
b640f042faa2 is bad, since it's also pretty likely that the test isn't
reproducing perfectly.

* Make bridge bug in linux 2.6.25b using Powerpc 405ep
From: zhong wang @ 2009-06-21 3:45 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 15916 bytes --]
hello all:
I encountered a very strange question, I am using the AMCC Powerpc 405ep its Emac0 received a single phy intel 971, Emac1 received RTL8305SB, they shared Mdio, Mdc. 2.6.25.10 I use the kernel.
The problem is to use the following command will be eth0, eth1 configured bridge .my borad will down often. Hope that helps!

uic_init_one
___alloc_bootmem
___alloc_bootmem_nopanic
alloc_arch_preferred_bootmem
In alloc_arch_preferred_bootmem we have:
if (WARN_ON_ONCE(slab_is_available()))
return kzalloc(size, GFP_NOWAIT);
Since the slab is available (it had better be or the call will return
NULL), we get the badness message, then a successful return from
kzalloc.
I believe the author wants something like:
if (slab_is_available())
return kzalloc(size, GFP_NOWAIT);
else
WARN_ON_ONCE(1);

Hmmm. That's b640f042faa2, which is another merge...
So you're still not there.

Makes sense I messed up somewhere. This is the commit that causes
problems:
Merge branch 'topic/slab/earlyboot' of git://git./linux/kernel/git/penberg/slab-2.6
* 'topic/slab/earlyboot' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6:
vgacon: use slab allocator instead of the bootmem allocator
irq: use kcalloc() instead of the bootmem allocator
sched: use slab in cpupri_init()
sched: use alloc_cpumask_var() instead of alloc_bootmem_cpumask_var()
memcg: don't use bootmem allocator in setup code
irq/cpumask: make memoryless node zero happy
x86: remove some alloc_bootmem_cpumask_var calling
vt: use kzalloc() instead of the bootmem allocator
sched: use kzalloc() instead of the bootmem allocator
init: introduce mm_init()
vmalloc: use kzalloc() instead of alloc_bootmem()
slab: setup allocators earlier in the boot sequence
bootmem: fix slab fallback on numa
bootmem: use slab if bootmem is no longer available
Makes sense since it is very early in the boot I get the badness. Also, there is no mention of JFS in the above logs.
Cheers,
Sean

The fact that your bisect ended at a merge essentially means that it is=20
invalid. As a merge does not introduce any actual change (unless it=20
includes changes to resolve conflicts), it normally cannot be the cause=20
of a regression.
So either you made a mistake when marking a commit as good or bad during=20
the bisect, or the "badness" does not trigger reliably, resulting in you=20
incorrectly marking a bad commit as good.
My suggestion would be to run the bisection again from the start.

I wouldn't trust the backtrace too much since it seems to keep
changing. It used to show __start_notes as the backtrace. This one is
with the head of Linus' tree as of a few minutes ago.
So I did a git bisect, and the problem goes back to June 11. The Warp
boots and seems to run fine. So I didn't notice until looking at the
logs for a different problem. I have since added a test to my
regression tests to look for badness or oops in the logs.
The git bisect returned:
871fa90791a6f83dd8e2e489feb9534a8c02088d is first bad commit
That is it, no more info.... strange. git show 8714...088d gives:

The Warp has jfs disabled, so I don't know why it would affect us,
especially this realy in the boot! Anyway, I tried to revert the patch:
$ git revert 871fa90791a6f83dd8e2e489feb9534a8c02088d
fatal: Commit 871fa90791a6f83dd8e2e489feb9534a8c02088d is a merge but no -m option was given.
So, anybody got an idea what is going on here? Or how I can revert the
patch. I am not a git expert, so if I am doing this wrong, let me know.

I switched to 2.6.30 and found that CONFIG_CC_OPTIMIZE_FOR_SIZE option
takes influence on delay. If it is enabled, there is delay. I tried to
shrink configuration, but I can't find a real module which responsible for this.

* howto redirect serial console
From: Mirek23 @ 2009-06-20 17:54 UTC (permalink / raw)
To: linuxppc-dev
I have a ppc405 based board with one serial interface which I use as a
console.
I would like to redirect or suppress, at run time, the console in order to
use the
serial port to control external serial devices.
I have tried (busybox) setconsole program to redirect the console to
/dev/null
but it did not work. What would be the elegant way to redirect or suppress
the serial console.
M.

Makes sense. I2C transactions better shouldn't be interrupted or
data loss might happen.

Ok - thanks - i'll push it to Linus probably later today.

Hi Ben,
Looks like the control enters pgtable_cache_init but rever returns. The
machine just hangs. I triggered a system reset via HMC to see what's
happening on the cpu. Here is the xmon o/p after a system reset.
The code that was executed was __mutex_lock_slowpath..

* [PATCH] powerpc: warp platform fix for i2c change
From: Sean MacLennan @ 2009-06-20 5:43 UTC (permalink / raw)
To: linuxppc-dev, ben-linux, Josh Boyer
A change to the i2c subsystem breaks the warp platform code. The patch
is cleaner anyway, the old way was a bit crufty.
For those with keen eyes, the gratuitous change in the string from
PIKA to Warp is just so the logs look a bit nicer. The following two
lines tend to be printed one after another.
Warp POST OK
Warp DTM thread running.
Yeah, this will be the third patch to warp.c submitted in this
release....
Cheers,
Sean
The i2c_client struct changed, breaking the code that looked for the ad7414
chip. Use the new of_find_i2c_device_by_node function added in 2.6.29.

Do we really want to keep of_serial.c ?
I fail to see the point in keeping -both- the of_serial (of_device
variant) and the legacy serial stuff which shims the device-tree into
platform devices.
They tend to clash with each other too, which is annoying.

That is strange. If I revert that commit, I get breakages on machines
here. It would be interesting to understand what the problem is here,
as we -do- use that kmem cache for allocating page tables, so we do
need it initialized that early. (IE, we can't allow vmalloc for example
to be called before the page table caches are initialized).
This will need more debugging and understanding as to why it hangs.
Cheers,
Ben.

* [PATCH] powerpc/amigaone: Limit ISA I/O range to 4k in the device tree
From: Gerhard Pircher @ 2009-06-19 21:42 UTC (permalink / raw)
To: linuxppc-dev list
The kernel reserves the I/O address space from 0x0 to 0xfff for legacy
ISA devices. Change the ranges property for the PCI2ISA bridge to match
the kernels behavior, even if the ranges property isn't used for now.

* [PATCH v3 2/2] fsldma: Add DMA_SLAVE support
From: Ira Snyder @ 2009-06-19 19:31 UTC (permalink / raw)
To: linuxppc-dev, Dan Williams, Li Yang, Kumar Gala
Use the DMA_SLAVE capability of the DMAEngine API to copy/from a
scatterlist into an arbitrary list of hardware address/length pairs.
This allows a single DMA transaction to copy data from several different
devices into a scatterlist at the same time.
This also adds support to enable some controller-specific features such as
external start and external pause for a DMA transaction.
Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu>
---
This patch depends on the "fsldma: split apart external pause and
request count features" patch.
After discussion with Dan Williams, this is the third version of the
DMA_SLAVE API for the Freescale DMA controller. I've tested it heavily
with both drivers I have written against this API, an FPGA programmer
and an FPGA data grabber.
Kumar, Dan asked me to add you to the CC list, so you can have a look at
this patch before he adds it to his tree.
The other two small patches I posted earlier are very helpful in testing
this functionality. They make the fsldma driver leave the BWC (bandwidth
control) bits alone on the 83xx controller, as well as making the
external start feature available on 83xx.
v2 -> v3:
* add support for setting DMA request count
v1 -> v2:
* move fsldma.h from include/linux to arch/powerpc/include/asm
* add kerneldoc documentation

* [PATCH 1/2] fsldma: split apart external pause and request count features
From: Ira Snyder @ 2009-06-19 19:26 UTC (permalink / raw)
To: linuxppc-dev, Li Yang, Dan Williams, Kumar Gala
When using the Freescale DMA controller in external control mode, both the
request count and external pause bits need to be setup correctly. This was
being done with the same function.
The 83xx controller lacks the external pause feature, but has a similar
feature called external start. This feature requires that the request count
bits be setup correctly.
Split the function into two parts, to make it possible to use the external
start feature on the 83xx controller.
Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu>
---
This patch splits apart the external pause feature from the request
count feature, to make it possible to use the external start feature on
the 83xx controller without writing the register directly after the
driver has been initialized.
The DMA_SLAVE patch depends on this patch.

You will have to program GPIO's to select appropriate external IRQ as
they are shared .

Subject: kilauea/405ex external interrupts
Hi,
I'm writing a linux driver that uses an external interrupt (ppc 405ex).
I'm using GPIO pin 30 (external IRQ 1) connected to UIC1. I'm aware of
the virtual interrupt stuff, so I added a new node to my device tree in
order to get proper virtual IRQ number. This node describes an external
event and its connection to UIC via the mentioned ext. int. Here is a
sample of the divce-tree:
..
UIC1: interrupt-controller1 {
compatible = "ibm,uic-405ex","ibm,uic";
interrupt-controller;
cell-index = <1>;
dcr-reg = <0x0d0 0x009>;
#address-cells = <0>;
#size-cells = <0>;
#interrupt-cells = <2>;
interrupts = <0x1e 0x4 0x1f 0x4>; /* cascade */
interrupt-parent = <&UIC0>;
};
EXTEVENT: external_event {
device_type = "external";
#address-cells = <0>;
#size-cells = <0>;
#interrupt-cells = <2>;
interrupts = <0x1e 0x1>;
interrupt-parent = <&UIC1>;
};
...
Then I use function "irq_of_parse_and_map()" which returns the virtual
IRQ number 22. So, "request_irq()" seems to be satisfied with this
number. I can see this interrupt in the /proc/interrupts. But! When I
connect a signal source to the pin 30, nothing happens - the interrupt
service routine isn't called.
Am I suppose to configure anything else? (e. g. pin multiplexing,
further device-tree tuning...) Thank you!
Best regards,
Ladi

Works for me (and some custom hardware I created [quite a while ago,
when I was young ;-)] that is not very tolerant to Byte-by-Byte-Transfers).
