I can confirm that a few fixes in v2.1 were missing, so trunk works
correctly, didn't you forget to rebuild the kernel when building trunk ?
Attached is a patch to v2.1 that contain the fixes backported from
trunk. Please try this patch and tell me if this works for you.
In fact, I've downloa

Shared memory are also accessible to non-rt tasks. Since user-space
realtime and non-realtime threads from the same process reside in the
same address space, the si

When configuring your kernel, configure the posix skin as a module. A
module xeno_posix.ko will then be compiled that you may load with
mo
Ok, thanks, i'll try. My old pc will have some job... :)
I still have a few questions :
- How can we load/unload posix skin ?
- Will this shared memory be accessible to non rt-task ?
- What's the simplest way to share information with a non rt-task ?
