Interfaces

1. With the setp command-line interface
2. With the qps monitor program
3. Direct manipulation via window manager integration
4. Using the AutoQOS feature (simple QOS management)

Reserves

The key parameters for QOS scheduling are Period and Slice. Processes belonging to a reserve are guaranteed to receive Slice microseconds of time every Period microseconds. A smooth 50 FPS animation might require a Slice of 7ms and a Period of 20ms, for example.

Linux-SRT's admission control algorithm will refuse to create new QOS contracts if to do so would over-commit the processor.

QOS scheduling takes precedence over the POSIX static RT priorities in order to ensure that guarantees are met.
