After a quick look at all architectures xenomai supports, it seems that we can implement atomic_cmpxchg for most of them in user-space. The only one for which I have a doubt is blackfin. Since linux for blackfin is uclinux, can we call cli/sti from user-space ? -- Gilles _______________________________________________ Xenomai-core mailing list Xenomaiemail@example.com https://mail.gna.org/listinfo/xenomai-core
