True, it was an great opportunity to see and talk to you guys. Here is a first list, please feel free to criticize it: - signals in primary domain (something that we almost forgot) We don't need that immediately but I think it would be very handy to have a standard method to register callbacks which are called once a thread has been signalled and is scheduled. - xnsynch_acquire using atomic_cmpxchg unconditionally (no #ifdefs) Atomic operations are always good :) - statistics of all mapped named heaps in /proc/xenomai/heap That would be very handy from our point of view. - unwapped access to user-space posix skin methods We'r using native skin... so I can't say much about that. - fast semaphores in user-space - syscall-less select ? I think, that'd be great. I think that'd help to decrease the execution time significantly. I haven't told you yet, but I also have managed to compile and run our Switch application in kernel space. That decreased the access time to a shared hardware resource protected by mutexes and using queues by 20% (avg. access time was 270us in kernel-space instead of 330us in user-space according to the histograms I generated).
