enter_from_user_mode(): 标记当前从用户态进入内核态,更新内核状态(如设置current->in_user_mode),并处理上下文切换相关工作(如审计、性能计数)。 local_irq_enable(): 启用本地中断。虽然系统调用通常在中断禁用状态下执行,但此处启用中断是为了支持内核抢占(允许更高优先级任务中断当前系统调用)。 current_thread...
ktime转换为ms的函数 通过ktime_to_ms函数可以从ktime转成ms的时间 ms=ktime_to_ms(ktime_get_boottime()); 如果计算某段代码运算时间,可以通过ktime_sub测试code 运行时间 ktime_t start, end, elapsed; start = ktime_get_boottime(); ... end = ktime_get_boottime(); elapsed = ktime_sub...
