Dear rt-freeBSDer's, I am interested in using free BSD with real time extensions for a machine controller application. Our application is being ported from a VME / VxWorks based system to a PC based system. We would like to minimize modifications to our existing code. Any help from someone familiar with VxWorks would certainly help alot. The information I need is mostly related to task scheduling and memory protection. Specifically, 1) does rt-freeBSD support threads? if yes to 1), 2) is the thread scheduling preemptive and priority based? (ie: higher priority tasks can preempt lower priority tasks) 3) does the thread scheduling support time sliced (round robin) scheduling at a given task priority level? if no to 1) 4) is process scheduling preemptive, priority based? and finally, 5) where can I get more info on the real time extensions to freeBSD? thanks in advance Rich To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-realtime" in the body of the message
