[Xenomai-help] Xenomai kernel user-space problem running testsuite

[Michael Galea]

I'm just starting with xenomai and am having troubles getting xenomai 
user space to talk to my kernel.

I build the kernel and user-space xenomai code and try to run `latency` 
from the test suite and get
mpc8360mds:# /usr/local/xenomai/bin/latency
Xenomai: incompatible feature set
(required="fastsem", present="nofastsem", missing="fastsem").


I have built xenomai from svn into my 2.6.26 powerpc kernel and it looks 
  good on the next boot, i.e. `dmesg |grep xeno -i` returns:
I-pipe: Domain Xenomai registered.
Xenomai: hal/powerpc started.
Xenomai: real-time nucleus v2.5-devel (Flying In A Blue Dream) loaded.
Xenomai: starting native API services.
Xenomai: starting POSIX services.
Xenomai: starting RTDM services.

The user-space builds and installs over NFS just fine:

./configure --host=ppc-unknown-linux-gnu --prefix=/usr/local/xenomai \
   CC=ppc_6xx-gcc CXX=ppc_6xx-g++ LD=ppc_6xx-ld
make
make DESTDIR=/opt/ppcrootmds/ install


I can't see any fastsem options in the kernel.  Does anyone have any 
advice?

Thanks

The trunk/ contains bleeding edge code. The powerpc port there is currently in a
state of flux, due to the introduction of fast user-space mutexes in the Xenomai
nucleus.

Please use the latest stable version such as 2.4.4, or our maintenance branch
instead: http://svn.gna.org/viewcvs/xenomai/branches/v2.4.x/.

Hi Phillipe,
	In trying to build xenomai 2.4.4 into the 2.6.26 kernel, using the 
default kconfig, I get

   CC      kernel/xenomai/arch/generic/hal.o
   LD      kernel/xenomai/arch/generic/xeno_hal.o
   LD      kernel/xenomai/arch/generic/built-in.o

You mentioned the maintenance branch, where can I find that?

Yeah, sorry, my mistake. You need to pull from the maintenance branch to run
2.6.26 kernels on v2.4.x, you can't use 2.4.4 vanilla.

Aside of this, Gilles's patch will successfully enable the fastsem support in
your kernel if you still want to live on the bleeding edge using the trunk. I
have just checked on an mpc836x, and the testsuite runs properly there as well
(cyclictest is the one that uses the fastsem stuff for now). Still no guarantee
though, I have only recently adapted Gilles's fastsem support to powerpc, and
this did not went through much testing yet.

It is supposed to be set by the Kconfig, but it looks like I forgot to
add it, so, you may try the attached patch.

FYI, with the ELDK the following command already works:

   ./configure --host=ppc-linux --prefix=/usr/local/xenomai
