下面是一些常见的ktime用法: 1.获取当前时间: ```c ktime_t current_time = ktime_get(); ``` 2.将ktime转换为纳秒: ```c s64 ns = ktime_to_ns(current_time); ``` 3.将纳秒转换为ktime: ```c ktime_t time = ns_to_ktime(ns); ``` 4.获取两个ktime之间的时间差: ```c k...
ktime_mono_to_real将单调时间转换为真实时间。ktime_get_ns等函数用于系统时间、真实时间等纳秒级获取。ktime_get_boottime_ts64和ktime_get_coarse_boottime_ts64用于获取启动时间。ktime_get_boottime_seconds获取秒级启动时间。ktime_get_clocktai_ts64和ktime_get_coarse_clocktai_ts64用于获取...

ktime_add_ns宏和ktime_sub_ns宏分别用于将纳秒值加到ktime_t类型的时间变量上和从ktime_t类型的时间变量中减去纳秒值。本质上这两个函数和上面的add、sub是相同的。 //71~74行staticinlinektime_ttimespec64_to_ktime(structtimespec64ts){returnktime_set(ts.tv_sec,ts.tv_nsec);} ...
