Your realtime thread needs to use one of the POSIX realtime scheduling options: SCHED_FIFO or SCHED_RR. For best results, only do this for the code that actually *needs* precise timing. > * How does normal priorities (nice, renice) play together with the > real-time kernel? They run at a lower priority than SCHED_FIFO or SCHED_RR threads. -- joq
