[Xenomai] problems with ipipe-3.10 on i.MX6

[Xenomai] problems with ipipe-3.10 on i.MX6

[Henri Roosen]

Hi,

We are currently transitioning our i.MX6 systems from kernel
ipipe-3.0-imx6q with Xenomai 2.6.2.1 to kernel ipipe-3.10 with Xenomai
2.6.4.

The application uses interrupts from external hardware, fed into the system
by a GPIO pin interrupt.

The system behaves very in-stable with the 3.10 version. I observe kernel
crashes, kernel null pointer dereferences, timer stalls and lock-ups at
various different places. The 3.0 version runs fine.

Are there any known issues like this with the ipipe-3.10 on an i.MX6?
Any suggestions how to tackle this problem?

Thanks,
Henri

Basically, as I explained yesterday, SOCs in the mainline I-pipe
patch for which I have no hardware are only build-tested. The I-pipe
patch for 3.0 is better maintained, because I have feedback from its
users.

Nevertheless, if you report patiently the errors you have reporting
one after we have solved the other, I will help you solve them all.
However, I would recommend using the 3.14 kernel, chances are that
it is not more stable, but when upgrading, there is no reason not to
upgrade to the latest.

Thanks Gilles for helping out! The reason we chose the ipipe-3.10 kernel is
because we want to merge with the Freescale L3.10.x-1.1.0 release later.
But I've tried the ipipe-3.14 release and also this version unfortunately
gives the same results.

The first thing that occurs is the following ipipe dump when we are calling
ioremap_nocache to map some device memory into the kernel. It is in the
non-rt ioctl of an rtdm driver:

I-pipe: Detected stalled head domain, probably caused by a bug.

I'm not sure how to find out what is wrong here. From code-review it seems
sane.
I guess this might cause the system instability, right?
The problem I observe after that is after some time the "i.MX Timer Tick"
stalls, which then locks up the system.

You are sure you are not calling ioremap with irqs off ?
Are you sure the current domain is Linux when calling ioremap ?

The current domain should be Linux because in the trace we see the
losyscall_event and the ioctl_nrt handler which is lrt_non_rt_ioctl_work.
How could I verify irq's are off?

Well, do you use rtdm_lock_get_irqsave or spin_lock_irqsave before
calling ioremap ?

Otherwise enable the I-pipe tracer, and cause a trace freeze instead
of the debug message.

Ok thanks, found an  rtdm_lock_get_irqsave in the path before calling
ioremap. Reworking the driver code now and get back to you with results.

I reworked the driver now and the 'stalled head domain' is not there
anymore.
However, the other symptoms did not disappear.

I currently observe 2 symptoms:
Either 1) a stall of the i.MX timer or 2) a kernel NULL pointer dereference.

The kernel trace of the NULL pointer dereference is as below:

Unable to handle kernel NULL pointer dereference at virtual address 00000000

As I said, I prefer handle one problem at a time, and pass to the

Who cares ? The i.MX timer has no reason to be used, the cortex a9
local timers should be used. Or are you booting a kernel compiled
without CONFIG_SMP ?

Well the kernel trace is not exactly as below, because your mailer
wrapped it, which makes it hard to read. Please try to get your
mailer not to wrap the trace, or failing that, simply attach a plain
text file with the trace.

__ipipe_do_sync_stage is jumping to address 0, some function pointer
is NULL. You would have to disassemble __ipipe_do_sync_stage around
offset 0x1cc to know what exactly. But it is probably an IRQ
handler. You can modify __ipipe_do_sync_stage code to emit a printk
with the irq number being currently being processed when its handler
is NULL. We will know what IRQ number has an issue.

I compiled without CONFIG_SMP as the symptoms seemed less random. However,
as you said, let's put this on ice for now and focus on the NULL pointer
dereference for now.

Please find the log.txt file attached, which shows the IRQ number that has
the issue (150: ethernet) as well as the output of /proc/interrupts and
/proc/xenomai/irq

I'll do some more tests to see if it is always IRQ 150.

Ok, if it is always 150, could you show us how the ethernet driver
does its request_irq ? If it does a set_type or something ?

To request the irq, the following statement is called:
ret = request_irq(irq, fec_enet_interrupt, IRQF_DISABLED, pdev->name, ndev);
I didn't find a set_type.

However, I'm not sure if I completely understood your question. Is it ok if
I point you to the file drivers/net/ethernet/freescale/fec_main.c, line
1983.

Yes, should be all in the included imx6qdl.dtsi file. Our board .dts file
includes the file and just sets the correct pinctrl, phy-mode and status to
okay, similar to what other boards do.

Ethernet communication is working and we are getting interrupts at first,
just after a while it stops working because of the NULL pointer dereference.
Any suggestion how to trace down this specific handler getting NULL-ed?

You can try using the I-pipe tracer. Enable the I-pipe tracer,
trigger a panic before printing anything when the bug happens (by
the way, which pointer is NULL, is it the irq handler, or the
interrupt acknowledge routine ?). Modify the I-pipe tracer to store
the current value of the handler instead of the timestamp in the
I-pipe trace structure, and the function printing the traces to cast
the timestamp to a pointer and print its value instead of computing
a difference. With enough back trace points, it should be clear in
the trace generated which function sets the pointer to NULL.

Alternatively, if you are ready to spend time in your processor
documentation, you can look for a way to program its hardware
breakpoints registers to watch the handler address once it has been
set.

However, it is only requested and registered in the Linux domain.

I'll use the I-pipe tracer now to make a trace at the moment the 150
interrupt gets handled in the xenomai domain..

I was actually wondering how __ipipe_next_irq() could come up with 150 when
in the xenomai domain.

I'm not sure, but the code in __ipipe_do_sync_stage() looks a bit strange
to me:
first p is set to the __ipipe_current_context and ipd to p->domain. Later
in the for-loop, p get updated again to __ipipe_current_context again (so
it is expected to change) but ipd is not updated to be set to the p->domain
again.
Was that on purpose or is the ipd = p->domain; statement missing inside the
for-loop?

The callee may not switch domain over an interrupt handler. Only CPU
migration may happen, which is what this assignment cares about.

rules in IRQ context over sync_stage are:

- no domain migration
- CPU migration possible over the root domain only

Each CPU holds an array of per-domain context areas, each context area

Yes, domain migration is visible in the I-pipe trace, the current
domain is indicated with a + in one of the two columns corresponding
to the two domains at the left of the trace, or with # if the
current domain is also "stalled", that is has run local_irq_save or
local_irq_disable for Linux domain, or hard_local_irq_save or
hard_local_irq_disable for Xenomai domain.

I don't see how that would be possible with Xenomai. The domain
migration gates are relax/harden calls in the nucleus, and these can
only be invoked from regular task contexts. But checking for peace of
mind won't harm anyway.

The tracer reports the current domain, see the heading line of a trace
for details about the symbols used.

I've added the check on p->domain != ipd at the end of the for-loop. That
one triggers in my case.

More debugging found:
1) the irq that triggers the domain switch is always irq 164 (0xa4). This
is the irq from our FPGA, fed to the i.MX6 via GPIO interrupt. The
interrupt handler is a primary domain handler, registered
using rtdm_irq_request(). I've added checks on primary domain at entry and
exit of the handler. Those checks never trigger, so the handler always
enters and leaves in primary domain.

2) our irq-handler is apparently not called when the switch occurs. I've
added a variable that is set to zero in __ipipe_do_sync_stage() after
__ipipe_next_irq(). Our handler sets it to a non-zero value. The value of
that variable is zero when the switch is detected at the end of the
for-loop.
I've noticed that when not setting the variable to zero, it has the value
that is returned by our handler at a spurous interrupt, which means the
last time our handler was called was not a valid interrupt... not sure what
to conclude from that.

I'm having trouble interpreting the ipipe-trace to find out what is really
going on. I've added a trace (fr7.txt) that was frozen at the point where
the domain-switch was detected at the end of the for-loop in
__ipipe_do_sync_stage(). Could you help me interpreting this trace to find
out where and why there is a domain switch during the irq handling?

Thanks!

I've added some more tracing to the ipipe-code:

At __ipipe_do_sync_stage()
ipipe_trace_begin(0x2222); // at enter
ipipe_trace_end(0x2222); // at leave
ipipe_trace_begin((irq << 16) | 0x2222); // at for-loop after irq is known
ipipe_trace_end((irq << 16) | 0x2222); // at end of for-loop

At __ipipe_dispatch_irq()
ipipe_trace_begin((irq << 16) | 0x1111); // at enter
ipipe_trace_end((irq << 16) | 0x1111); // at leave

:~# cat /proc/xenomai/irq
IRQ         CPU0
 87:     2441549         [timer]
164:     2192094         fpga0:164
1027:      254734         [virtual]

~# cat /proc/interrupts
           CPU0
 34:          0       GIC  sdma
 51:          0       GIC  rtc alarm
 54:      50372       GIC  mmc0
 59:        693       GIC  IMX-uart
 70:        792       GIC  21a8000.i2c
 87:     232403       GIC  i.MX Timer Tick
150:     108432       GIC  2188000.ethernet
151:          0       GIC  2188000.ethernet
Err:          0

This leads to the attached trace fr12.txt.

Line 3586: Entry to __ipipe_do_sync_stage()
Line 3587: __ipipe_do_sync_stage found pending IRQ 1027
Line 3710: Another entry to __ipipe_do_sync_stage()! This is before end of
the previous IRQ 1027!
Line 3711: __ipipe_do_sync_stage found pending IRQ 164. This is the last
entry where the fpga is handled. This is in primary domain.
Line 3735: it seems to me the irqhandler_fpga is completed all in primary
domain.
Line 3790: Here is the end of __ipipe_do_sync_stage() handling IRQ 1027!
Line 3792: Switch to secondary domain
Line 4012: There is no end logging of __ipipe_do_sync_stage() handling IRQ
164, but the freeze entry shows it is completing irq 164, so at that entry
the end would be if there was no freeze. This is in primary domain.

These are the interesting entries that occurred to me. So my questions:
- Should it be possible at line 3710 to enter again before ending the
previous call?
- When the end of IRQ 1027 is finally there at line 3790, why is there a
switch to secondary? Handling IRQ 164 is not completed yet.

Is the failure visible in this trace, or what tracing can I add to trace
down the actual problem?

Thanks!
Henri.

I don't want to be rude or push anyone, as I know everyone has a lot to do
by himself. But it would really help me forward if someone could have a
look at the trace I made and answer the questions above.
If there is no apparent sign in the trace, please point me to some places
where I can add some extra tracing to get down to the root cause.

Hi Henri,

I know I said I would help you, but I am not very familiar with this
code, so Philippe will be much more efficient. But he is busy at the
moment and will not be able to help you before some time.

Thanks Gilles, I appreciate the update. However the following short
question might be something you are familiar with and I would appreciate if
you could answer it:
In the traces I see gic_mute and gic_unmute, while in between the
gic_handle_irq is traced, which triggers our fpga-handler too.

Does that mean we have a problem with the gic-muting? What can I do to
verify?

Thanks!

No, gic_mute only prevents the secondary mode interrupts from being
delivered. And since the GPIO irq has a primary mode interrupt, the
mute function does not mute it. So, everything seems fine so far.

Maybe a short question that you or Philippe can shortly answer:
I see two __ipipe_sync_pipeline() calls running concurrently. Is that
allowed? If not, which flag or check should prevent both to be running
concurrently?

One (triggered from the virtual interrupt) makes an explicit switch to
secondary domain:
__ipipe_set_current_domain(ipipe_root_domain) in __ipipe_do_sync_pipeline().
This triggers the domain switch in the other current call
to __ipipe_do_sync_stage.

virtual irq path:

__ipipe_restore_head(0)
__ipipe_sync_pipeline(ipipe_head_domain) // __ipipe_current_domain != top
__ipipe_do_sync_pipeline(ipipe_head_domain);
__ipipe_set_current_context(ipipe_head_domain);
__ipipe_sync_stage();
__ipipe_do_sync_stage() // for irq 1027
__ipipe_set_current_domain(ipipe_root_domain); //  <------- secondary
domain switch!

gpio-interrupt path:

__ipipe_dispatch_irq()
__ipipe_sync_pipeline() // !test_bit(IPIPE_STALL_FLAG,
&ipipe_this_cpu_context(top)->status)
__ipipe_sync_stage()
__ipipe_do_sync_stage()

Thanks for the effort!

Yes, this is allowed, when the head domain preempts the root one, which
is the case here if the gpio path is a real-time one.

I can't see this happening in the fr7 trace you sent, at least not at
line 3790 as you mentioned. What can be seen soon after, at line 3820 is
the control being given back to the regular kernel, with a virq being
handled to run an APC, on behalf of a task called "LTRmgr.e<something>"
(i.e. which was preempted by the virq in the root domain, which has been
delayed by rt activity before it could call the APC handler).

I don't see any forced transition from rt to nrt mode in this particular
time span, only the nrt mode getting the CPU back at line 3820, once the
rt activity goes to sleep, and therefore relinquishes control to the
regular kernel.

What I can see is a quite long rt processing (1.62 ms, from spot 1771 ->
151) preempting the root domain, and no relax in between.

You may want to add user-defined traces using ipipe_trace_special(),
when you think the domain has spuriously changed, or when some assertion
does not hold true unexpectedly. Looking at the complete trace flow may
shed some light.

The exact patch with your instrumentation is needed too, so that we can
understand your assumptions, and how you check them. You may want to
simplify it to the bone, only with the very minimal traces required to
demonstrate the bad behavior you suspect.

Maybe there is a bug, but so far I could find not any manifestation of
it in the traces you sent.

Thanks Philippe for your answers!

The virtual irq path and gpio path described above were a conclusion from a
different trace file, which is now attached as well as the code
instrumentation patch.

So please have a look at trace file fr20.txt.

The interesting lines:
3578: virtual irq 0x403 gets dispatched
3586: __ipipe_do_sync_pipeline sets the current domain to the head
(primary) domain
3592: __ipipe_do_sync_stage handling irq 0x403 (this only ends on line 3803)
3642: __irq_svc for irq 0x62 (this is the GPIO1_0-15 multiplexed interrupt
on the gic)
3658: irq 0xa4 is dispatched, the GPIO1_4 interrupt
3675: __ipipe_do_sync_stage handling irq 0xa4, while the one started at
line 3592 did not end yet. Also, this one started here is not ended before
the end of the trace!
3803: __ipipe_do_sync_stage ends for irq 0x403
3804: __ipipe_do_sync_stage ends as a whole
3807: __ipipe_do_sync_pipeline explicitly switched to ipipe_root_domain
(secondary domain) using __ipipe_set_current_domain(ipipe_root_domain);

In my opinion this breaks rule 'no domain migration during sync_stage' you
mentioned in one of your earlier emails as sync_stage for irq 0xa4 is still
ongoing and later triggers the freeze at line 4012.

So this was the reason for my question about __ipipe_do_sync_pipeline being
allowed to run concurrently, as the one explicitly switches the domain to
primary and the other path doesn't allow for domain switching while still
in __ipipe_do_sync_stage().

So where did this go wrong?
- should __ipipe_do_sync_pipeline() really be allowed to run concurrently?
- or should __ipipe_do_sync_stage() for irq 0xa4 already have finished
before the other path switches domains. I guess the other path played all
head - interrupts already.
- or is there something else I overlooked or should trace further into?
Please let me know.

Thanks for your time and effort!
Henri

Please read my previous email with the attached traces and questions first.
But to find out why __ipipe_do_sync_stage() for irq 0xa4 doesn't complete,
I've added some ipipe_trace_special to xnintr_irq_handler() and it turns
out it runs until the xnpod_schedule(); call in xnintr_irq_handler(). It
only returns from the schedule call just before the freeze gets triggered.

I'll patiently await your response for now and wait with providing new
traces because that might get confusing. I'm sure the last trace (fr20.txt)
and this email provide enough clarity to draw some conclusions and/or push
me in a direction where to best trace down the root cause.

Thanks!
Henri

I'm sorry, I don't want to be rude to trigger this again, but unfortunately
I have a customer deadline and this problem is currently a show stopper. It
would be really great if you could give some input to this issue so we can
keep on making progress in solving this.

Also I found out the switching of domain during __ipipe_do_sync_stage
happens with kernel ipipe-3.0-imx6q and Xenomai 2.6.2.1, but it somehow
doesn't show a visible issue. Likely this issue is in earlier versions too,
maybe even for other architectures.

Thanks for your time and effort!
Henri

FWIW, I'm not contributing free software as a result of having too much
free time. I have customers and contract deadlines to cope with as well
right now, and unfortunately, I can't divert the time which would be
required for such analysis at the moment.

to get this solved. It seems nobody else but you can help me right now. I
understand getting support is our risk for choosing free software.

If you know any other option for me to get this solved, then please let me
know. Else, I hope you would still be willing to spend a little free time
to look into this issue. Any help is appreciated!

Thanks,
