Are there any plans to move toward a less expensive RTOS replacement for vxWorks? I am interested in RTEMS but would also like to be able to use a commercial product (without having to put up with Wind River).
RTEMS is available as a commercial product - you can pay oarcorp for support if you don't want to do everything yourself. Currently that's the leading alternative to vxWorks for IOCs with real hardware interfaces, although I'm personally interested in Jaluna, an open source (but also commercially supported) derivative of ChorusOS. It shouldn't be very hard to write the OSI routines to get EPICS running on Jaluna, which provides full Posix realtime support
Unfortunately, my performance evaluation software had a bug which resulted in apparently inferior latency figures when using the POSIX API.
Repeated tests with the corrected benchmarking software yielded the same low latencies measured when using the native API.
and a choice of 3 memory models, although nobody's doing this yet. http://www.jaluna.com/
