CONFIG_TIMEOUT_64BIT

Store kernel timeouts in 64 bit precision

Type: bool

Help

When this option is true, the k_ticks_t values passed to
kernel APIs will be a 64 bit quantity, allowing the use of
larger values (and higher precision tick rates) without fear
of overflowing the 32 bit word.  This feature also gates the
availability of absolute timeout values (which require the
extra precision).
