Hi,
next-20150619 is un-bootable (it `drowns` in warnings).
I modified irq_move_masked_irq() to do WARN_ONCE() instead of WARN_ON
every !irqd_can_balance(), and here it is:

Do you guys want to replace WAN_ON() with WARN_ONCE(), perhaps? This, of course,
doesn't fix anything; but at least one can boot the system. (not really a patch,
just an idea).

Indeed. We really want to clear the move pending bit before the can
balance check. Patch below. But that does not explain why this happens
in the first place.
Can you please send me a full dmesg, kernel config and output of
/proc/interrupts ? (Private mail is fine, or upload it to some place)
Thanks,

Thanks for providing the data. I think I know what happens.
Something in the kernel (not yet clear what) tries to move the hpet
irq 0 by calling irq_set_affinity(). That's an kernel internal
interface which does not check whether the NO BALANCE flag is set for
the irq. So the call runs and triggers the move from next interrupt
machinery which ends up calling irq_move_masked_irq() and that trips
over the flag and yells.
That's why I changed the WARN to a pr_warn() because we already know
the call stack.
So the core behaviour is inconsistent. We let the caller of
irq_set_affinity() succeed and yell later because we think it's wrong.
I'm pretty sure that we must drop the check for NO BALANCE in
irq_move_masked_irq() and only check for the per_cpu bit, but at the
same time I really want to know where that call to irq_set_affinity(irq0)
is coming from.
Can you please collect the output of /proc/timer_list for the previous
patch and then replace the previous patch with the one below and
gather all the data again?
Thanks,
tglx

It's 10pm here in Korea and I'm out of office already. I'll try
to collect the data tomorrow (or on Monday in the worst case).
Thank you.

Hi Thomas,
Maybe it's caused by the hpet driver itself?
irq_set_affinity() may set the IRQD_SETAFFINITY_PENDING flag,
thus triggering the warning.
---------------------------------------------------------------
static int hpet_setup_irq(struct hpet_dev *dev)
{
if (request_irq(dev->irq, hpet_interrupt_handler,
IRQF_TIMER | IRQF_NOBALANCING,
dev->name, dev))
return -1;
disable_irq(dev->irq);
irq_set_affinity(dev->irq, cpumask_of(dev->cpu));
enable_irq(dev->irq);
printk(KERN_DEBUG "hpet: %s irq %d for MSI\n",
dev->name, dev->irq);
return 0;
}
-------------------------------------------------------------
Thanks!
Gerry

And the usage pattern seems reasonable, the IRQF_NOBALANCING flag
means nobody may change the affinity except myself:)

Right, that's why I removed the restriction. I just wonder why we have
not seen that before ...

I suspected it's caused by the hierarchy irqdomain at first glance
because the multiple irq_datas issue, but seems it's not after checking
the code. It will only be triggered if HPET works in MSI mode instead of
legacy IRQ mode, but still need more investigation here.

just a note,
I compile/run every linux-next on at least two different
x86-64 boxen, w/o changing the .config a lot.

Right. And what confuses me is that this happens on irq0, which is
ioapic edge.
Thanks,

Hi Thomas,
One possible cause is that hpet_assign_irq() fails, and the
code below treats 0 as a valid irq number(which should be fixed).
----------------------------------------------------------------------
static void hpet_msi_capability_lookup()
{
.........................
irq = hpet_assign_irq(hpet_domain, hdev, hdev->num);
if (irq < 0)
continue;
sprintf(hdev->name, "hpet%d", i);
hdev->num = i;
hdev->irq = irq;
hdev->flags = 0;
...............................
}
Hi Sergey,
Could you please help to apply the debug patch below
and check the log message?
Thanks!
Gerry

OK. It's setup_ioapic_dest() and I understand now where this all comes
from.
One last request. Can you please provide /proc/timer_list and dmesg
from a mainline kernel for comparison?
Thanks,

x86/hpet: Check for irq==0 when allocating hpet MSI interrupts
irq == 0 is not a valid irq for a irqdomain MSI allocation, but hpet
code checks only for negative return values.

genirq: Remove bogus restriction in irq_move_mask_irq()
If an interrupt is marked with the no balancing flag, we still allow
setting the affinity for such an interrupt from the kernel itself, but
for interrupts which move the affinity from interrupt context via
irq_move_mask_irq() this runs into a check for the no balancing flag,
which in turn ends up with an endless storm of stack dumps because the
move pending flag is not reset.
Allow the move for interrupts which have the no balancing flag set and
clear the move pending bit before checking for interrupts with the per
cpu flag set.

Thanks for providing that. As I feared already, there is a regression
as well. The new code fails to allocated more than one hpet MSI
interrupt. Fix below.
Thanks,

Subject: x86/hpet: Use proper hpet device number for MSI allocation
From: Thomas Gleixner <tglx@linutronix.de>
Date: Sun, 21 Jun 2015 16:21:50 +0200
hpet_assign_irq() is called with hpet_device->num as "hardware
interrupt number", but hpet_device->num is initialized after the
interrupt has been assigned, so it's always 0. As a consequence only
the first MSI allocation succeeds, the following ones fail because the
"hardware interrupt number" already exists.
Move the initialization of dev->num and other fields before the call
to hpet_assign_irq(), which is the ordering before the offending
commit which introduced that regression.
