From: Ingo Molnar <mingo@elte.hu>
When CONFIG_PREEMPT_RT_FULL is enabled, tasklets run as threads,
and spinlocks turn are mutexes. But this can cause issues with
tasks disabling tasklets. A tasklet runs under ksoftirqd, and
if a tasklets are disabled with tasklet_disable(), the tasklet
count is increased. When a tasklet runs, it checks this counter
and if it is set, it adds itself back on the softirq queue and
returns.
The problem arises in RT because ksoftirq will see that a softirq
is ready to run (the tasklet softirq just re-armed itself), and will
not sleep, but instead run the softirqs again. The tasklet softirq
will still see that the count is non-zero and will not execute
the tasklet and requeue itself on the softirq again, which will
cause ksoftirqd to run it again and again and again.
It gets worse because ksoftirqd runs as a real-time thread.
If it preempted the task that disabled tasklets, and that task
has migration disabled, or can't run for other reasons, the tasklet
softirq will never run because the count will never be zero, and
ksoftirqd will go into an infinite loop. As an RT task, it this
becomes a big problem.
This is a hack solution to have tasklet_disable stop tasklets, and
when a tasklet runs, instead of requeueing the tasklet softirqd
it delays it. When tasklet_enable() is called, and tasklets are
waiting, then the tasklet_enable() will kick the tasklets to continue.
This prevents the lock up from ksoftirq going into an infinite loop.

Commit fa27271bc8d2("genirq: Fixup poll handling") introduced a
regression that broke irqfixup/irqpoll for some hardware configurations.
Amidst reorganizing 'try_one_irq', that patch removed a test that
checked for 'action->handler' returning IRQ_HANDLED, before acting on
the interrupt. Restoring this test back returns the functionality lost
since 2.6.39. In the current set of tests, after 'action' is set, it
must precede '!action->next' to take effect.
With this and my previous patch to irq/spurious.c, c75d720fca8a, all
IRQ regressions that I have encountered are fixed.

When unbinding a device so that I could pass it through to a KVM VM, I
got the lockdep report below. It looks like a legitimate lock
ordering problem:
- domain_context_mapping_one() takes iommu->lock and calls
iommu_support_dev_iotlb(), which takes device_domain_lock (inside
iommu->lock).
- domain_remove_one_dev_info() starts by taking device_domain_lock
then takes iommu->lock inside it (near the end of the function).
So this is the classic AB-BA deadlock. It looks like a safe fix is to
simply release device_domain_lock a bit earlier, since as far as I can
tell, it doesn't protect any of the stuff accessed at the end of
domain_remove_one_dev_info() anyway.
BTW, the use of device_domain_lock looks a bit unsafe to me... it's
at least not obvious to me why we aren't vulnerable to the race below:
iommu_support_dev_iotlb()
domain_remove_dev_info()
lock device_domain_lock
find info
unlock device_domain_lock
lock device_domain_lock
find same info
unlock device_domain_lock
free_devinfo_mem(info)
do stuff with info after it's free
However I don't understand the locking here well enough to know if
this is a real problem, let alone what the best fix is.
Anyway here's the full lockdep output that prompted all of this:

Did this patch not make it into stable releases other than 3.1. I
couldn't find it in any other stable tress prior to 3.1.

Ah, this was done in the early stable-rt releases. Where we took
mainline fixes as long as they were in tglx's tree. But today the
stable-rt tree waits for mainline fixes to come in via the stable tree
so we don't do something like this. That is, miss getting a fix into
stable. Yeah, this should be added to 3.0. (looks to be already in 3.2
and 3.4).
Greg,
Can you add the following commit to the 3.0 stable tree. We've had this
in v3.0-rt for some time now. :-/

I had to edit the path to the file, but it looks like it applies
properly now, thanks.

Thanks,
Just in case, below is what I applied to v3.0-rt.

Subject: [PATCH] intel-iommu: Fix AB-BA lockdep report
When unbinding a device so that I could pass it through to a KVM VM, I
got the lockdep report below. It looks like a legitimate lock
ordering problem:
- domain_context_mapping_one() takes iommu->lock and calls
iommu_support_dev_iotlb(), which takes device_domain_lock (inside
iommu->lock).
- domain_remove_one_dev_info() starts by taking device_domain_lock
then takes iommu->lock inside it (near the end of the function).
So this is the classic AB-BA deadlock. It looks like a safe fix is to
simply release device_domain_lock a bit earlier, since as far as I can
tell, it doesn't protect any of the stuff accessed at the end of
domain_remove_one_dev_info() anyway.
BTW, the use of device_domain_lock looks a bit unsafe to me... it's
at least not obvious to me why we aren't vulnerable to the race below:
iommu_support_dev_iotlb()
domain_remove_dev_info()
lock device_domain_lock
find info
unlock device_domain_lock
lock device_domain_lock
find same info
unlock device_domain_lock
free_devinfo_mem(info)
do stuff with info after it's free
However I don't understand the locking here well enough to know if
this is a real problem, let alone what the best fix is.
Anyway here's the full lockdep output that prompted all of this:

Instead of blacklisting known-unsupported cpuid leaves, whitelist known-
supported leaves. This is more conservative and prevents us from reporting
features we don't support. Also whitelist a few more leaves while at it.

XSAVE valid feature scanning, but it was wrong. It was not considering
the sparse nature of this bitfield, instead reading values from
uninitialized members of the entries array.
This patch now separates subleaf indicies from KVM's array indicies
and fills the entry before querying it's value.
This fixes AVX support in KVM guests.

makes no sense to acquire the waitqueue lock for wakeup all. Provide

Commit 30765b92 ("slab, lockdep: Annotate the locks before using
them") moves the init_lock_keys() call from after g_cpucache_up =
FULL, to before it. And overlooks the fact that init_node_lock_keys()
tests for it and ignores everything !FULL.
Introduce a LATE stage and change the lockdep test to be <LATE.

Your emails seem to be damaged in interesting ways.
I assume the patch is going through the lockdep tree? If so, please make
sure you include Christoph's ACK in the changelog.

This is for the stable-rt tree. This patch is on its way, but you'll
have to talk to Peter about Acks and such.
But this brings up a point. I'll start adding [RT] to the subject of the
patches as well to not confuse people.
Thanks,

Ok, this is a nearly blind shot, but i was expieriencing strange idle time
behaviour with this Ingo Molnar patch. The idle time was never incremented as
read from /proc/stat for several minutes. The system itself was behaving fine
and had definetly not 100% load which was also verified with top.
I hadn't had the time to investigate further and my tests where with an ealier
release with the Ingo Molnar Tasklet patch on top.
Hopefully i will find some time to test this stuff further but it will
probably tuesday CET.
Best regards
Tim

Did some other time accounting increase instead ?

Hi

Yes, the other time seemed to be increasing normally.
I should also point out, that this phenomen was not always happening, but only
sometimes and then again disapeared without any known reason.

Hmm, then are you sure that the tasklet patch causes the bug? Or perhaps
it only changes the timing to cause it. The bug may be without the patch
too.

Well, we are running the preempt rt patchset 3.0 since the rt-9 release and we
have not seen this kind of error. It just started popping up after i applied
the patch which i took directly from the mailing list when it was posted,
since we had this ksoftirq issue especially after firmware update when ubifs
has been updated.
The bad thing is that it is not happening deterministic but seemingly at
random. But i will try your next prerelease and will report any results.
My patch is also not completly vanilla mainline. I am using the recomended
patch from ubifs/master, some small platform patches and some timer patches
Thomas Gleixner knows best about.
Best regards
Tim

Must be either config related, or something got fixed meanwhile.

May be patch is corrupted because it say this while patching:
patch -p1 <11.patch
patching file drivers/acpi/ec.c
patching file drivers/acpi/internal.h
patch unexpectedly ends in middle of line
or just not fix this issue but problem steel present after this patch,
and seems i hit another one, i attach full dmesg.
