-/*! Configuration for time_cc.
- * Report the cumulative counter of time for which a flag is true as rate counter.
- * For example, for each second that the flag is true, increment a rate counter.
- *
- * The flag to be monitored is reported by time_cc_set_flag().
- *
- * The granularity defines how much time one rate counter increment represents:
- * the default configuration is gran_usec = 1000000, i.e. one rate counter increment represents one second.
- *
- * Reporting as rate counter is configurable by round_threshold_usec and forget_sum_usec, examples:
- *
- * round_threshold_usec:
- * - To get "ceil()" behavior, set round_threshold_usec = 1. This increments the rate counter for each gran_usec period
- *   where the flag was seen true, even if it was true for only a very short fraction of a gran_usec period.
- * - To get "round()" behavior, set round_threshold_usec = half of gran_usec. The rate counter increments when the flag
- *   has been true for 0.5 of a gran_usec (and then again at 1.5 * gran_usec of 'true' flag). round_threshold_usec = 0
- *   is a special value that means to use half of gran_usec.
- * - To get "floor()" behavior, set round_threshold_usec >= gran_usec. The rate counter increments when reaching full
- *   gran_usec periods of the flag being true.
- *
- * forget_sum_usec:
- * This is a tradeoff between the accuracy of the reported rate counter and making sure that the events reported are not
- * irrelevantly long ago.
- * - To keep sub-granularity-period surplus time forever, set forget_sum_usec = 0.
- * - To keep surplus time for up to a minute, set forget_sum_usec = 60000000 (60 seconds).
- * - To get rid of "leftover" time (almost) immediately after the flag goes false, set forget_sum_usec = 1.
- * - If gran_usec is set to one second and forget_sum_usec is set to one minute, the reported rate counter has a
- *   possible inaccuracy of 1/60th, but makes sure that no timings older than a minute affect the current reports.
- *
- * Reporting modes in detail:
- *
- * The rate_ctr increments when the cumulative counter passes round_threshold_usec (default: half of gran_usec).
