[Xenomai-help] Xenomai suspends my kernel thread

[Xenomai-help] Xenomai suspends my kernel thread

[Branko]

[-- Attachment #1: Type: text/plain, Size: 16237 bytes --]

Hello all!

 

I would be most grateful for your help.

 

I ported my PowerPC GNU/Linux C/C++ application to Xenomai.

When I ran the application everything looked fine.

However, with more intense data exchange, one of my interrupt handler
threads did not react any longer.

I looked at the /var/log/messages file and I saw that Xenomai suspended my
thread due to the exception 768.

 

According to https://mail.gna.org/public/xenomai-help/2006-11/msg00233.html
I disabled CONFIG_XENO_OPT_DEBUG 

from my kernel configuration, but the behaviour of my application did not
change.

 

Please find my kernel configuration bellow.

 

Looking forward to receiving your suggestions.

 

Best regards,

Branko

What version of Xenomai do you use ? Does your application use fork ? If
yes, then you should switch to Xenomai 2.3.1.

A lot of different situations may lead to a 0x300 exception code
(including application errors), not necessarily related to the PTE
misses issue we recently fixed for 2.6.

Which kernel version, which Adeos patch revision are you using?

I'm afraid you are out of luck with 2.4/ppc kernels if PTE misses are
suspected to occur. IIRC, they have only been fixed by recent Adeos
patches for the Adeos 2.6/arm and 2.6/x86[_64] series. There would be no
straightforward solution to your problem then, fixing the issue for
2.6/ppc too would be required.
