Hi -

I have a Dell OptiPlex 9020 running 3.14.17. I am trying to get this system to run 3.14.17 with xenomai (using the 3.14.17 patch in the xenomai 2.6.4 source).

The computer hangs when I select the kernel at “Loading initial ram disk”. I tried booting into recovery mode and go the following output:

Kernel panic - not syncing: timer doesn’t work through Interrupt-remapped IO-APIC.
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.14.17-xenomai-2.6.4.

I’m having a hard time finding the source of the error. I’ve attached my config file. Any suggestions appreciated!

Does the exact same kernel configuration, but without CONFIG_IPIPE
and CONFIG_XENOMAI work ?

I disabled CONFIG_XENOMAI and CONFIG_IPIPE - but when recompiling the kernel, I get:

kernel/fork.c: In function ‘dup_task_struct’:
kernel/fork.c:317:29: error: ‘struct thread_info’ has no member named ‘ipipe_data’
__ipipe_init_threadinfo(&ti->pipe_data);
make[2] *** [kernel/fork.o] Error 1
make[1] *** [kernel] Error 2

I checked the config and both of those are set to “n”. What am I missing?

Sorry, I may have misunderstood but if you’re asking if 3.14.17 works out of the box (withough being patched), then yes it does work.

The question is: with the exact same configuration?

I can't get the kernel to compile if I turn those two options off (but leave everything else the same).

I get the following error: 

kernel/fork.c: In function ‘dup_task_struct’:
kernel/fork.c:317:29: error: ‘struct thread_info’ has no member named ‘ipipe_data’
__ipipe_init_threadinfo(&ti->pipe_data);
make[2] *** [kernel/fork.o] Error 1
make[1] *** [kernel] Error 2

You were talking about the unpatched kernel. Does the unpatched
kernel work with the exact same configuration (only without
CONFIG_IPIPE and CONFIG_XENOMAI).

Yes, I compiled an unpatched kernel with all the same options (turn off processor ACPI, frequency scaling, etc) and I can successfully boot up.

With the patched kernel, if I provide “noapci” to the kernel boot commands, I can get past the “Loading initial ramdisk” but then the system freezes prior to getting to the login screen.

I tried the same config with a patched 3.14.17 kernel on a different machine (not the same model as the one that is hanging at initrd) - and the system boots up successfully into 3.14.17 with xenomai.

I am sorry, but this does not look like the "exact same
configuration". To get the exact same configuration, simply copy the
damn .config file, the unpatched kernel kbuild system should cope
with the missing CONFIG_XENOMAI and CONFIG_IPIPE. This will remove
any uncertainty. Run diff to get 100% sure that nothing else is
changed.

Also, as mentioned in the documentation, starting from a "full
monty" configuration like the ones you find in a distribution, and
simply removing CONFIG_ACPI_PROCESSOR, CONFIG_CPUFREQ) IS NOT the
recommended way. It is better to start from a lean configuration
where only what you need is enabled, this makes the kernel build
process much faster and so further attempts less expensive, and you
have more chances to void enabling an option that nobody else uses
with Xenomai.

The obvious answer, which I believe you can find many times
mentioned in the archives, and even in the troubleshooting guide Is
to disable the kernel "silent" mode if it is not disabled, and
enable early printk.

Seeing a user which does not read and follow the basic guides makes
me reluctant to answer him.

Sorry, Gilles - I do not mean to waste your time. I have spent time on the website and I have already disabled kernel silent and built early printk. Those didn’t help the case.

Going back to your original question about does it work with the exact same configuration (with the exception of CONFIG_XENOMAI and CONFIG_IPIPE) - the answer is yes.

I have successfully compiled a Xenomai patched 3.14.17 kernel by copying the original config file over and rebuilding from there. 

The diff between the config that I previously shared with you (which did not work) and the config that worked has no differences except for the fact that the missing IPIPE and Xenomai statements.

The machine that I am working on is a Dell Optiplex 9020 with a Intel i5-4670 processor.

Sorry. I missed that information. Please try the latest available
I-pipe patch for Linux 3.14 instead of the one in Xenomai sources.

Please turn off CONFIG_IRQ_REMAP or boot the kernel with intremap=off.
This feature is not yet compatible with I-pipe. I guess we should encode
this into the x86 patch.

I tried Jan's suggestion and it works with the 3.14.17-x84-6 ipipe patch 
- I can boot in get to a desktop/etc. However, the latencies are all 
over the place. I am seeing worst-case latencies anywhere between 2us-50us.

I tried Gilles' suggestion, too - and compiled with 3.14.17-x86-9 ipipe 
patch. Same thing as above.

I read around online about interrupt remapping - and I can't seem to 
find anything that hints at why this turning it off would cause the 
latencies to be all over the place.

Any thoughts/guidance appreciated!

Yogi

It shouldn't. There may be other reasons. But beware, in our tests the
Core i5/i7 showed about 29 us max. latency (running dohell), but
depending on the load, that can go up to 70 us (running a handbrake
video encoding session). What you see might actually be the best you
can get.

> Any thoughts/guidance appreciated!

You seem to be running a desktop distribution. Try leaving desktop
mode (kill the window manager / X). Check you're not running binary
graphics drivers. Unload as many drivers as you can.

Just some ideas; you don't seem to have provided a dmesg log.

I've been using "stress" to put a load on the system while running the 
xenomai latency test.

You are correct. It looks like if I blacklist the radeon module (which I 
compiled with the kernel as a module, not using a binary), the latencies 
drop to 8-10us. I

Sorry - dmesg log is attached. From just looking at the radeon specific 
messages, I don't quite see what the problem could be except for 
something internal to the radeon driver.

The information that would be interesting would be whether you are
running the proprietary module. Even though proprietary modules
seem like being compiled, they in fact compile a small glue over a
big binary blob. Obviously, the I-pipe patch can not patch that
binary blob, so, you can only hope that the glue compiles what the
I-pipe patch would want to patch.

Anyway, this log message:
> [    0.880890] drm: module has bad taint, not creating trace events
Suggests that you are running the proprietary blob.

Also, something to note, once again, is that if you care about
performances, you should not have a kernel with everything enabled.
Notably not any form of tracing or debugging.

On the other hand, this message:
> [   21.886328] kvm: module has bad taint, not creating trace events
would suggest that you have rather a module/kernel mismatch. This
too can be detrimental to performances if you are running plain
linux modules with an I-pipe patched kernel.

However, looking at all this, I do not find any evidence that
disabling irq remapping created any performance issue, and I really
do not understand the logic that lead you to this weird conclusion.

Well, at least we now know that you are running with a HD8xxx GPU, and
what I find intriguing is the date reported by the driver:

[drm] Initialized radeon 2.37.0 20080528 for 0000:01:00.0 on minor 0

I would definitely check your driver. especially verify that fglrx is
NOT running. Apart from that:

[    0.877121] video: module verification failed: signature and/or
required key missing - tainting kernel
[ 0.880890] drm: module has bad taint, not creating trace events
[ 0.884665] radeon: module has bad taint, not creating trace events
...

you have no less than 6 tainting warnings for a kernel you claim to
have built yourself. Are you sure you didn't turn the module
versioning check off ? To me it seems your modules (or not all of
them) and kernel do not match. If so, all bets are off and this setup
could only be running by coincidence. You could even be running
modules that aren't patched at all in a patched kernel.

I also see a 'vboxdrv' driver. I have absolutely no idea what its
impact on I-pipe would be, but it sounds bad to me (along with kvm).
This is the type of thing you would only enable / try when the system
is working properly. I wouldn't even allow it to initialize.

Apart from that, there is indeed not much that can be learnt from your
dmesg log...

Other suggestions include trying to use the on-CPU video (but you must
have the proper chipset for this), remove the Radeon and save some
energy in the process.

It is imperative that you do as Gilles said: minimize the .config
(you'd be amazed how much you can throw away and still keep the Ubuntu
desktop). It compiles much faster and at least you are more likely to
throw an eye on the compile log afterwards.
