Designing Real Time Linux Applications for Multicore Systems - (PPT)

摘要

Real-time Guidelines: Applications: 1. Set the priorities of tasks in the system - Ensure real-time tasks get higher priority - Also ensure that the triggers for real-time tasks (e.g. interrupts) also get highest priority 2. Locking pages in RAM - reduce page swapping overhead, use Huge-TLB-FS 3. Use of high-resolution timers, with real-time clocks and not relative clocks 4. Use scheduler tracing tools: (CONFIG_SCHED_TRACER) to debug.
