[Xenomai-help] Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled

Hi there

I'm using ubuntu 6.06 LTS.
I patched a 2.6.19.1 vanilla kernel with xenomai 2.3.0 adeos
(Processor type is Pentuim III)
The realtime section has been left at the default settings.

The kernel compiles and boots ok.

Userspace Xenomai has been compiled with the --disable-x86-tsc option

When i try to run the latency test, i get the following error

Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled
(modprobe xeno_native?)

The kernel .config file shows that the native skin is supposed to be
compiled
into the kernel and CONFIG_SENO_OPT_PERVASIVE=y

Any help to solve this problem would be appreciated

Thanx
Vicki

I bet you are still running your old kernel...

Anyway, check the boot messages and the content of /proc/xenomai,
specifically .../interfaces.

Hi
Thanx for the reply

uname -al shows that the kernel is the patched kernel (2.6.19.1). Ubuntu's
kernel is 2.6.15
Xenomai is failing to load because of the APIC

Passing lapic=1 as a boot parameter causes a kernel panic

Going to try recompiling with APIC disabled (if it is)

Keep well
Vicki

Hi,

I have compiled and installed Xenomai and am able to boot from the Xenomai
kernel. when running the latency test I get:
Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled.
(modprobe xeno_native?)

linux 2.6.25, xeno 2.4.4

It seems that APIC is not starting. I have tried lapic parameter in the GRUB
but still the same?
Any ideas please?

Dehann

Did you exclude those reasons mentioned above?

Please send us your kernel config. Which architecture and CPU do you have?

If you want anyone other than me to answer then don't drop the mailing 
list from CC in the future ...

The APIC situation is explained in the TROUBLESHOOTING file. So, please,
read this file.
