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/timekeeping.c中的定义如下...
ktime_get_real_ts64于linux v3.17版本面世，最初以宏定义形式存在。在linux v5.0版本中，随着do_gettimeofday的退役，ktime_get_real_ts64正式登场。其定义位于kernel/time/timekeeping.c，声明则在include/linux/timekeeping.h。具体实现和使用详情，需查阅相关源代码和文档。

至linux v2.0版本，正式升级为外部接口。其定义位于arch/i386/kernel/time.c。然而，随着linux v5.0的更新，do_gettimeofday退出历史舞台。原因在于struct timeval在32bit机器上面临2038问题。替代函数为ktime_get_real_ts64。这一替代被官方文档明确指出，详细信息可参考"linux kernel documentation"中的...

In "ioctl_cfg80211.c" I've replaced: struct timespec ts; get_monotonic_boottime(&ts); with: struct timespec64 ts; ktime_get_boottime_ts64(&ts); Then the DKMS module compiles properly! Please could you adapt the code accordingly. ...
