Function Documentation

long long nano2ticks ( long long  nano )

inline

No conversions are needed in userspace.

Time conversions from nano seconds to system ticks.

The HBGenerator needs this for accurate timekeeping, which is an anachronism in userspace.

NANO_TIME rtos_get_time_ns ( void  )

inline

Get "system" time in nanoseconds.

TICK_TIME rtos_get_time_ticks ( void  )

This function should return ticks, but we use ticks == nsecs in userspace.
