Step 1: Enable time-slicing
configUSE_TIME_SLICING must be set to 1 to allow equal priority tasks to share CPU time.Step 2: Ensure tasks yield or block
Tasks should periodically yield or block to allow others to run.Final Answer:
Enable time-slicing and ensure tasks yield/block -> Option AQuick Check:
Time-slicing plus yielding ensures fair CPU sharing [OK]
Quick Trick: Enable time-slicing and yield for fair CPU sharing [OK]
Common Mistakes:
- Assigning different priorities defeats equal priority scheduling
- Disabling preemption prevents time-slicing
- Increasing tick rate alone does not guarantee fairness
