yes, futex is there. You can check it in
arch/microblaze/include/asm/futex.h

It is possible to connect several MicroBlazes but the problem is missing 
cache coherency modul. I hope that Xilinx will release any version which

We haven't done any significant work to support it but it is expected 
solution which will happen.

Thanks for input,
Michal
