Hi!

I am experiencing problems with Xenomai on a Beckhoff C6920 PC.

Most times Xenomai works correclty, but at random I'm getting the following messages when booting:
[    0.459466] Xenomai: hal/i386 started.
[    0.471028] Xenomai: real-time nucleus v2.4.9 (Big Bad Moon) loaded.
[    0.522072] Xenomai: native skin init failed, code -19.
[    0.522135] Xenomai: starting POSIX services.
[    0.572046] Xenomai: POSIX skin init failed, code -19.
[    0.622037] Xenomai: RTDM skin init failed, code -19.

So, Xenomai may start correctly many times and than fails to start for 10 times or it fails to
start every second boot. It's completly random, it may happen on a cold boot or on a reboot.

It seems to have something to do with the APIC timer, as the kernel also writes this message
when Xenomai fails to start:
[    0.290132] APIC timer disabled due to verification failure

The kernel options listed in the Xenomai installation and troubleshooting guides are already disabled,
C1E is also disabled in BIOS.

I have attached the complete kernel log and the kernel configuration to this e-mail.

The software components I'm using are:
Linux: 2.6.29.5
Xenomai: 2.4.9
Adeos: adeos-ipipe-2.6.29.5-x86-2.4.02

I know, it's pretty old, but we've been running these versions for almost 3 years on our production system
on older hardware without any problems. So, maybe there is a simple solution to get rid of this problem.

Best regarts,
  Christoph

Hi!

Meanwhile I found out that the problem does not occur when the X86_PM_TIMER option is enabled in the kernel.

Is it OK to enable X86_PM_TIMER? The Xenomai documentation does not explicitly say if this option should be
enabled or disabled, but I've read about some issues on the mailing list where this option caused problems.

Best regards,
  Christoph

Hi,

Xenomai will use a timer only if it has not been shutdown by Linux. So,
if enabling the PM_TIMER causes the APIC to be shut down then yes, you
should disable PM_TIMER. Though with CONFIG_SMP, there is one LAPIC
timer whereas there is only one PM_TIMER.

What is the result of cat /proc/timer_list when the APIC was disabled?

Regards.

I have also turned on APIC debugging with apic=debug to see whats going on:

Thats the output where everything is fine:

And here is the output where Xenomai fails to initialize (note the value of jiffies delta):

With X86_PM_TIMER enabled in kernel the APIC timer verification seems to be skipped,
I got no failure in this constellation anymore:

mode 1 is shutdown, that is the reason why Xenomai will not start.

mode 3 means that the timer is running (in one-shot mode, but that is
not really important), in that case Xenomai can work.

Same here.

Well the clock speed is weird too... So, it would be interesting to find
out what happens during the APIC timer verification. Though you may
spend some time figuring out something which was fixed in later
revisions, so, I would advise to do a quick test of Xenomai 2.6.1 to see
if it still has the problem.

Hi,

I tried out Xenomai 2.6.1 with both Linux 2.6.38.8 and 3.2.21 and CONFIG_X86_PM_TIMER disabled,
the problem still exists with these versions.

[    0.021152] CPU0: Intel Celeron(R) Dual-Core CPU       T3100  @ 1.90GHz stepping 0a
[    0.021391] Using local APIC timer interrupts.
[    0.021392] calibrating APIC timer ...
[    0.021998] ... lapic delta = 20112246
[    0.021998] ..... delta 20112246
[    0.021998] ..... mult: 863945707
[    0.021998] ..... calibration result: 3217959
[    0.021998] ..... CPU clock speed is -12379.-059 MHz.
[    0.021998] ..... host bus clock speed is 3217.0959 MHz.
[    0.021998] ... verify APIC timer
[    1.662609] ... jiffies delta = 1609
[    1.662705] APIC timer disabled due to verification failure


Also, enabling CONFIG_X86_PM_TIMER seems to solve the problem in these newer versions.


Best regards,
  Christoph
