Hello Kim, Please have a look at *rt*.*wiki*.kernel.org If you use a preempt-rt Kernel you shoud note following points: - for realtime processes use SCHED_FIFO or SCHED_RR - you can raise the priority up to 99 (only root) - if you want to have a nice realtime performance for your control proces

[etherlab-users] EtherCAT realtime priorities

2011-01-19 Thread Kim H. Madsen
Hi We are using the user space interface with the application running at a real time priority on a PREEMPT_RT system. Until now we have been running the EtherCAT master on priority 0 (SCHED_OTHER). We are considering to raise the priority of the ETherCAT to a real time priority (SCHED_FIFO). We
