- pps: Round to closest integer in pps_event() The comment above bintime2timespec() says: When converting between timestamps on parallel timescales of differing resolutions it is historical and scientific practice to round down. However, the delta_nsec value is a time difference and not a timestamp. Also the rounding errors accumulate in the frequency accumulator, see hardpps(). So, rounding to the closest integer is probably slightly better. Reviewed by: imp Pull Request: https://github.com/freebsd/freebsd-src/pull/604

- pps: Simplify the nsec calculation in pps_event() Let A be the current calculation of the frequency accumulator (pps_fcount) update in pps_event() scale = (uint64_t)1 << 63; scale /= captc->tc_frequency; scale *= 2; bt.sec = 0; bt.frac = 0; bintime_addx(&bt, scale * tcount); bintime2timespec(&bt, &ts); hardpps(tsp, ts.tv_nsec + 1000000000 * ts.tv_sec); and hardpps(..., delta_nsec): u_nsec = delta_nsec; if (u_nsec > (NANOSECOND >> 1)) u_nsec -= NANOSECOND; else if (u_nsec < -(NANOSECOND >> 1)) u_nsec += NANOSECOND; pps_fcount += u_nsec; This change introduces a new calculation which is slightly simpler and more straight forward. Name it B. Consider the following sample values with a tcount of 2000000100 and a tc_frequency of 2000000000 (2GHz). For A, the scale is 9223372036. Then scale * tcount is 18446744994337203600 which is larger than UINT64_MAX (= 18446744073709551615). The result is 920627651984 == 18446744994337203600 % UINT64_MAX. Since all operands are unsigned the result is well defined through modulo arithmetic. The result of bintime2timespec(&bt, &ts) is 49. This is equal to the correct result 1000000049 % NANOSECOND. In hardpps(), both conditional statements are not executed and pps_fcount is incremented by 49. For the new calculation B, we have 1000000000 * tcount is 2000000100000000000 which is less than UINT64_MAX. This yields after the division with tc_frequency the correct result of 1000000050 for delta_nsec. In hardpps(), the first conditional statement is executed and pps_fcount is incremented by 50. This shows that both methods yield roughly the same results. However, method B is easier to understand and requires fewer conditional statements.

- pps: Simplify capture and event processing Use local variables for the captured timehand and timecounter in pps_event(). This fixes a potential issue in the nsec preparation for hardpps(). Here the timecounter was accessed through the captured timehand after the generation was checked. Make a snapshot of the relevent timehand values early in pps_event(). Check the timehand generation only once during the capture and event processing. Use atomic_thread_fence_acq() similar to the other readers.
