radeon in dom0/ivtv in domU: irq 16 nobody cared

radeon in dom0/ivtv in domU: irq 16 nobody cared

[Mark Hurenkamp]

Hi,


With a fairly recent (~march 29th) xen/next kernel and a recent  
xen-4.0.rc9-pre build, i still get
occasional 'nobody cared' messages on a IRQ which is shared between  
dom0 radeon
driver, and domU ivtv driver. Usually this happens while i'm working  
on the desktop,
and a recording is active in domU.

Is there something i can do about this?


Regards,
Mark.

Yes,

Please e-mail your full serial log output, your cat /proc/interrupts,
and 'lspci -vvv' output. This is to say, for both Dom0 and DomU.

I think I am able to reproduce this with one device (in DomU) that shares the IRQ
(17) with another device that is in Dom0. In Dom0 I get:

For the "nobody cared" message to trigger, then there must either have
been no interrupt handlers at all, or they all returned IRQ_NONE.

So in theory, if irq 17 has an active driver on it, then its irq handler
should see the interrupt, poke the device, go "huh, nothing for me to
do, must be a spurious interrupt from something else sharing the irq",
and I guess return IRQ_NONE.

So what stops this?  If the irq isn't being shared with anything in
dom0, we should be careful not even map the interrupt into dom0 (though
I suspect we only ever map, never unmap, interrupts).

But if the interrupt is being shared, I think we need a proxy interrupt
handler installed by pciback (pcistub?)to absorb apparently spurious
interrupts, which always returns IRQ_HANDLED (and perhaps have some of
its own screaming interrupt logic in case something has gone awry)?

Or if not that, what?  How has this problem been avoided before?

That's very strange, but I suspect there's a lot of mysterious magic
around piix ide controller interrupts relating to backwards compat, etc.

I've done ahead and made an attempt at this, but it isn't completly
finished. The code is in pv/pciback-2.6.32 branch. To make it work the
'fake_irq_handler' paramater has to be set to 1.
> 
> Or if not that, what?  How has this problem been avoided before?


In 2.6.18 there was logic to return IRQ_HANDLED if the IRQ line was
shared with another guest. Basically this:


 914 int irq_ignore_unhandled(unsigned int irq)
 915 {
 916         struct physdev_irq_status_query irq_status = { .irq = irq
};
 917 
 918         if (!is_running_on_xen())
 919                 return 0;
 920 
 921         if (HYPERVISOR_physdev_op(PHYSDEVOP_irq_status_query,
&irq_status))
 922                 return 0;
 923         return !!(irq_status.flags & XENIRQSTAT_shared);
 924 }

Which would be called on any spurrios interrupt and it would
shortcircuit it. I tried something similar by setting up the fake IRQ
handler if this hypercall returned a positive value. But the call logic
in any device driver is that it first does the PCI configuration writes
(enable the device, etc) and then calls request_irq which binds the
interrupt to the event channel and then this above hypercall returns
the shared flag. But the pciback/pcifront isn't used for request_irq
so I need to figure out some mechanism to schedule this hypercall later
on in Dom0 to figure out if there is a need to insert the IRQ handler.


Anyhow, my test rig that has a couple of IRQ lines shared across (A Dell
Dimension something) various devices and is doing something wacky with
or without this patch where the interrupt lines on the IOAPIC get masked
(and only if a specific IRQ line gets shared - 17) and no interrupts get
sent to either Dom0 or DomU. Manually unmasking the IOAPIC starts the
flow of interrupts thought it becomes a storm. Not sure if it is just
faulty hardware or operator, so please consider the above code/branch completly
untested.

Does the kernel get to know about the passed-through irqs?  I was
thinking that at pass-through time it would install the handler in dom0
on the irq (and all other domains sharing the irq), and then the handler
could do that hypercall and return IRQ_HANDLED / IRQ_NONE accordingly.

Hrm.  You could instrument Xen to see who's masking the interrupt.

That was my other thought. But that means that the handler has to
do a hypercall - which I thought is a bit too heavy handed considering we only need
to know whether it is shared only once. The fake irq handler gets
disabled if the domain is turned off/pci hotplug removed.

Currently the fake IRQ handler is installed on the IRQ that is requested
by the guest. So if the IRQ is not shared in Dom0, it still gets
inserted in (and it won't receive any interrupts since that IRQ line is
not shared with the domain 0).

<nods>Right now I am, digging through code to figure out how to make this
happen without inserting to much code in the handler which would have
slowed the machine to a crawl.

It could just return IRQ_HANDLED unconditionally, without doing the
hypercall.  Remember you also need it in the domU and any other domU
using the same GSI.

Yep.

Just for clarity's sake, you mean GSI for each instance of IRQ here, right?

I was thinking of something very dumb and ad-hoc, like putting an
explicit "if (gsi == X && masking) print something".

Re: radeon in dom0/ivtv in domU: irq 16 nobody cared

Meanwhile i moved to an even more recent xen/stable-2.6.32 (.11) kernel,
and a xen-4.0.0 release, the problem still shows.

I've attached the requested information, although it was collected after a fresh boot
(thus the problem has not occurred yet), with the same xen & kernel as were in use 
when the problem last exposed itself. 

Note that during boot, there are a lot of warnings about slowpath and schedule_bug,
most of these occur when starting xen-domains.

I've been working on this problem and came up with some code that
follows Jeremy suggestion. But my test rig shows some weird behavior
(with and without the patch) and starts having an IRQ storm which
I think are unrelated.

Anyhow, what I would like you test is to provide 'noirqdebug' flag on
your Linux kernel command line. That should take care of the 'nobody
cared IRQ'. Please test and see if you your machine is more or less
sluggish.


Also, please do run this:
while (true)
do
 sleep 10
 cat /proc/interrupts | grep 16
done

during the lifecycle of the whole machine. I am curious to see whether
you also get an IRQ storm (or if it is just a trickle - which is OK)
after launching the DomU guest.

Ok, i just rebooted my system with this setting, Will start some  
recordings,
and see how it behaves.

I put a monitor in place, we'll see what happens. As far as i can see  
now,
the radeon driver registers the IRQ, but doesn't seem to do much with it
during normal use (counter is still 0 after about 15 minutes running X  
now).
Perhaps it is meant for opengl or some accelerated function, or my  
xserver
is just not using the drivers full potential.
Which makes it all the easier to see a storm should it occur ;-)

Regards,
Mark.

It probably only gets used if the X server is driving the card faster
than it can keep up, so the queue starts getting filled.  Its quite
likely that normal X/text stuff just doesn't get close to exerting the
card at all.

If your setup allows it, you could try turning on "desktop effects" to
see what happens then...

I have had my system up and running for several days now, and indeed
the IRQ nobody cared has not occured. I do not see my system behave
any more sluggish than before. All the scheduled recordings seem to have
been recorded correctly (sometimes up to 3 in parallel).

Having done so, i notice that the count in dom0 and domU is identical,
and seems to increase with about ~100 or so per second while domU is
recording from /dev/video0. To me that does not seem unusual.


Probably unrelated, but although i do have compiz running, and quite some eye-
candy enabled in my dom0 Kde environement, the radeon driver still doesn't 
seem to generate any interupts. 


And probably also unrelated, dmesg in the domU shows a lot of these messages:
