[Xenomai-help] problem with gtk

[Ludovic Lemarchand]

Hello

I have patched a debian kernel 2.6.26 with Xenomai 2.4.7.

When I use Xenomai with gnome environment my computer freeze.

So, I have install kde. Its works perfectly but when I use a gtk
software like firefox or eclipse, my computer freeze too.

I don't understand why Xenomai is not compatible with gtk.


I thank you for any response and suggestions.

Could you try Xenomai 2.4.8 with the included patch for Linux 2.6.29 ?

Hello

I solved the problem of the freeze.

I disabled the Symmetric multi-processing support (SMP) and now it works with no freeze.

That is not normal. Does the SMP kernel freeze with Xenomai 2.4.8 and
the ipipe patch for 2.6.29 it contains ?

If yes, then please try to get the kernel logs and post them on this list.

Hello

I use Xenomai 2.4.7 with the ipipe patch for 2.6.26 because I should use a 2.6.26 Debian kernel.

Well, this version of the I-pipe patch is known to be broken on SMP
machines. It was fixed but in later patches (the earliest version fixed
is 2.6.26 I think).

And you can compile Xenomai as a debian package without resorting to the
xenomai repository, see:

http://www.xenomai.org/index.php/Building_Debian_packages

Well, I am afraid these instructions are a bit out-dated since they are
refering to svn. So, please use git-buildpackage instead of
svn-buildpackage (the url of xenomai git repository is available on
xenomai main page at http://www.xenomai.org).

Besides, I am having SATA controller problems with the latest 2.6.26
kernel from debian (unpatched I mean), so I would recommend to stay away
from it.

I meant 2.6.28. The first fixed version is 2.6.28.

I am using debian stable, so all I have is the package name 2.6.26-2,
and it is an ahci sata, I would expect sata_nv to be nvidia ?

Any x86 patch older than adeos-ipipe-2.6.28.9-x86-2.2-07 is broken on
recent kernel releases on SMP hardware running a SMP kernel config, due
to a TLB flush issue. 2.6.26 patches are known to have this issue. You
should definitely use anything >= 2.2-07 for the x86 series.

[Xenomai-help] message pipe services

[LEMARCHAND Ludovic]

Hello

I have an application with xenomai task and a standard linux process in order to establish a communication between them.
I have read that message pipe services is the best solution.

So, I tested the pipe.c exemple, but it doesn't compile. I have include native/pipe.h library but it doesn't find RT_PIPE_MSG and rt_pipe_alloc().
So, I take a look at the library and this elements are declared between ifdef __KERNEL__ ... endif, but this condition is never validate.

How can I register my xenomai task as __KERNEL__ ? Is it automatic, have I something to do ?

Thank you for any response and suggestions.

See:
http://www.xenomai.org/documentation/trunk/html/api/group__pipe.html

Each service documentation tells the context from which it may be
called. Some services may only be called from kernel context (that is,
if you are compiling a kernel module), some other may be called from
user-space.

What you are likely looking for is rt_pipe_create.
