如何在 PREEMPT_DYNAMIC 内核中启用实时模式

enable-realtime-mode.sh

sudo sh -c 'echo full > /sys/kernel/debug/sched/preempt'

sudo sh -c 'echo full > /sys/kernel/debug/sched/preempt'

该命令通过向对应的 debug 文件写入 “full”，在 PREEMPT_DYNAMIC 内核中启用实时模式。这使内核能够以完全可抢占模式运行，对实时应用至关重要。

你可以通过运行以下命令恢复为 voluntary 模式：

disable-realtime-mode.sh

sudo sh -c 'echo voluntary > /sys/kernel/debug/sched/preempt'

sudo sh -c 'echo voluntary > /sys/kernel/debug/sched/preempt'
