ktime_get_real_ts64 ktime_get_real_ts64函数诞生于linux v3.17,当时是一个宏定义如下: externvoidgetnstimeofday64(structtimespec64*tv);#define ktime_get_real_ts64(ts) getnstimeofday64(ts) 在linux v5.0中,也就是do_gettimeofday正式退役时,我们看看ktime_get_real_ts64的样子。其在kernel/time/ti...
函数名称:ktime_get_real_seconds - Get the seconds portion of CLOCK_REALTIME* Returns the wall clock seconds since 1970. This replaces the* get_seconds() interface which is not y2038 safe on 32bit systems. 函数原型:time64_t ktime_get_real_seconds(void) 返回类型:time64_t 参数:无934...
ktime_get_boot_fast_ns ktime_get_boot_fast_ns - NMI safe and fast access to boot clock.* To keep it NMI safe since we're accessing from tracing, we're not using a* separate timekeeper with updates to monotonic clock and boot offset* protected with seqlocks __ktime_get_real_fast_...
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...

do_sys_settimeofday64函数和do_settimeofday64类似,但它还接受一个时区结构tz作为参数。它是一个更高层次的系统调用,能够更全面地处理时间和时区设置 //41~45行externvoidktime_get_raw_ts64(structtimespec64*ts);externvoidktime_get_ts64(structtimespec64*ts);externvoidktime_get_real_ts64(structtimespec64...
