Hello,
I am working on porting x86 RTAI based application/kernel-modules to
Xenomai for Blackfin (BF537). We are using RTAI's FPU and I want to
ask: Do Xenomai support FPU operations on Blackfin platform (in
kernel) ?

I am no blackfin expert, but from the code, I am afraid not. But it
seems Linux does not support Blackfin FPU either. And in fact, blackfins
have no FPU.
