I can't boot 3.16rc3 on my Globalscale Mirabox (Armada 370):
Linus 3.16rc3 tree, mvebu_v7_defconfig + another multiplatform soc
(e.g. omap3/4), enable IOMMU and the soc specific backend (IOMMU + OMAP_IOMMU)
and it gives a solid hang at boot - no output on console, so i can't debug
further.
The same multiplatform kernel, with support for a wide range of socs and iommu
(omap, exynos, imx, versatile, calxeda, tegra, etcetc), boots fine with
every other board, but hangs on armada: am i the only experiencing this?
is this a known issue?

Thanks for reporting the issue. Just to make it easy to reproduce the
problem, could post the complete .config that exhibits the issue?
Thanks a lot!

here it is:
mvebu_v7_defconfig + EXT4FS + DEVTMPFS (to ease booting my board) + OMAP 4
support + IOMMU_SUPPORT/OMAP_IOMMU
i'm pretty sure it's IOMMU related since if i disable it, the board boots fine.
attached is the actual config file

I managed to reproduced the hang with the configuration joined.
As you can in my .config see I also activated earlyprintk to have more
trace. The problem seems to come to something at the interaction between
PCIe and IOMMU:

Thanks for reproducing the problem. In my opinion, the problem is in
drivers/iommu/omap-iommu.c, which gets compiled when
CONFIG_OMAP_IOMMU=y. This file does:
static int __init omap_iommu_init(void)
{
struct kmem_cache *p;
const unsigned long flags = SLAB_HWCACHE_ALIGN;
size_t align = 1 << 10; /* L2 pagetable alignement */
p = kmem_cache_create("iopte_cache", IOPTE_TABLE_SIZE, align, flags,
iopte_cachep_ctor);
if (!p)
return -ENOMEM;
iopte_cachep = p;
bus_set_iommu(&platform_bus_type, &omap_iommu_ops);
return platform_driver_register(&omap_iommu_driver);
}
/* must be ready before omap3isp is probed */
subsys_initcall(omap_iommu_init);
So it calls bus_set_iommu() unconditionally, without caring@all
whether it is running on a platform that actually cares about OMAP
IOMMU. And then later on, a bus notifier of the IOMMU subsystem gets
called, and some NULL pointer gets dereferenced. I'm pretty sure that
if you comment out this subsys_initcall(), you won't see the problem
anymore.
However, this code has been around since a while, so I don't know if
it's actually the change that makes it visible. Maybe some other IOMMU
core internal change makes it actually visible. But this
subsys_initcall() that does random stuff without caring about the
platform it runs on anyway looks incorrect.

Indeed I comment it, and I didn't see the problem anymore.

I think that nobody until now have run this configuration.

Hello,
If you have touched the OMAP IOMMU driver recently, please read on.

Hum, indeed, I was assuming multi_v7_defconfig would have that enabled,
but it only has the Tegra IOMMU enabled, and not the OMAP IOMMU one.
So, the bug clearly belongs to the developers of the OMAP IOMMU driver,
so I've added a bunch of people who touched this driver recently in Cc.
Thanks!

To add more information: I thought the problem was here from a long time
so I tested a 3.14 kernel, and in this case the kernel booted without any
problem. So the bug is pretty recent. I will do a last test with 3.15 and
I will keep you inform.

So it also boot well in 3.15 and then failed in 3.16-rc3. I hope it will
help the developers of the OMAP IOMMU driver to fix it.

The OMAP IOMMU driver isn't the only one registering itself with the platform
bus at probe time, regardless of the system the kernel runs on. Some IOMMU
drivers push the bus_set_iommu() call to the probe function, but that's not a
good solution either, as we could have several instances of the same IOMMU,
and all of them should be probed before the bus_set_iommu() call.
We need a quick fix for v3.16, but we also need to fix bus_set_iommu(). That's
on my to-do list for <insert some fuzzy future date here>, but if you want to
give it a go, please feel free to do so. In all cases, this is a good occasion
to start discussing the problem. Any opinion on what the perfect API would
look like ?

Thank you. I've had a look at the OMAP IOMMU driver changes between v3.15 and
v3.16-rc3, and didn't find at first sight any change that could explain the
crash.

I added a few printks and found that the problem is that the iommu_bus_notifier is
called for the 'pci' bus type, which has a null iommu_ops.

I reverted the above commits but nothing changed. I'm far from being an expert,
but it sounds odd to have this bus notifier (that got registered for the
platform bus type) called by a pci bus type.
This doesn't look like a mvebu-specific problem, other platforms should be
affected as well. I'm Ccing GregKH, in case he has an idea what's going on.

Why wouldn't the PCI bus set this up for its devices? Are you
"assuming" you know the bus type and that's the issue?
I see the a number of different places this is being initialized for the
pci bus.
Ah, look at drivers/iommu/fsl_pamu_domain.c, odds are, it shouldn't be
doing that logic in the pamu_domain_init() code, using the same bus ops
for different bus types, that's ripe for major problems...

Why wouldn't the PCI bus set this up for its devices? Are you
"assuming" you know the bus type and that's the issue?
I see the a number of different places this is being initialized for the
pci bus.
Ah, look at drivers/iommu/fsl_pamu_domain.c, odds are, it shouldn't be
doing that logic in the pamu_domain_init() code, using the same bus ops
for different bus types, that's ripe for major problems...

Thanks for looking at this.
I guess I snipped the thread and lost most of the information about the panic.
Here's the original bug report:
http://www.spinics.net/lists/arm-kernel/msg344059.html
The problem reported involves enabling OMAP IOMMU driver and not any other IOMMU
driver. Doing some tracing and adding a few prints, we found that
omap_iommu_init() sets a bus notifier for the platform bus type:
omap_iommu_init -> bus_set_iommu -> iommu_bus_init:
static void iommu_bus_init(struct bus_type *bus, struct iommu_ops *ops)
{
bus_register_notifier(bus, &iommu_bus_nb);
bus_for_each_dev(bus, NULL, ops, add_iommu_group);
}
But the iommu bus notifier gets called for the 'pci' bus type, which
has the iommu_ops field NULL (since it hasn't been set for iommu).
The panic is here when the NULL field is dereferenced:
static int iommu_bus_notifier(struct notifier_block *nb,
unsigned long action, void *data)
{
struct device *dev = data;
struct iommu_ops *ops = dev->bus->iommu_ops;

Maybe I'm missing something, but since the fsl driver is not enabled it has
nothing to do. And since the OMAP IOMMU doesn't set the iommu bus notifier
for the 'pci' bus type, I was wondering if there's a problem with the bus
notifier itself.
I hope the above makes sense.
Thanks again for helping out,

So this is what needs to be figured out, how is the notifier being
called with a PCI device? Who else called iommu_bus_init() for the PCI
bus?

Nobody. The only caller of iommu_bus_init() the above OMAP IOMMU.
However, I found something interesting. Tried to bisect this without much
luck; I did two bisects and ended up in the same merge commit:
# good: [0f16aa3c24a216d14d7f0587e1cbd2c1b51a38f3] Merge tag 'samsung-dt-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/dt

So, after doing a few diff's between that good and bad and searching for
"bus_notifier" changes, saw something strange in arch/arm/mach-mvebu/coherency.c.
It seems bus_register_notifier() is been called for platform and pci devices
with the *same* notifier block. Haven't looked close enough, but you mentioned
that could cause trouble?
This patch fixes the issue here:

Paolo, can you apply it and confirm it fixes the problem?
Greg, can you confirm using the same notifier block pointer
for two different bus types makes the bus notifier go nuts?

The bus notifier doesn't "go nuts", but the call back functions must be
able to handle the devices for that specific bus being passed to the
function for it.
Again, you shouldn't ever mix bus types with the same notifier unless
you _really_ know what you are doing, and even then, I wouldn't
recommend it.

The bus notifier doesn't "go nuts", but the call back functions must be
able to handle the devices for that specific bus being passed to the
function for it.
Again, you shouldn't ever mix bus types with the same notifier unless
you _really_ know what you are doing, and even then, I wouldn't
recommend it.

Looking at how notifier_chain_register() is implemented (which gets
called by bus_register_notifier() ->
blocking_notifier_chain_register()), I indeed don't see how a single
'struct notifier_block' can be registered on multiple notifier chains,
so I believe your patch is correct.
Thanks for the investigation!
