Conclusion and best practices

Successful QNX porting requires: 

• Deep architectural understanding: Recognize where Linux assumptions break in QNX.

• Incremental porting: Start with core functionality, then add features.

• Continuous testing: Validate real-time behavior at each stage of porting and ensure library test suites work on QNX ported library.

• Performance tuning: Optimize for QNX's constrained environment.
