(__stp_estimate_cpufreq): Compute kHz instead of MHz. (__stp_time_timer_callback, __stp_init_time): Compute base in ns. (__stp_time_cpufreq_callback): Record kHz instead of MHz. (_stp_init_time): Record kHz, and disable preemption to avoid a race in the cpufreq notifier. (_stp_gettimeofday_ns): Converted from _stp_gettimeofday_us. tapset/ * timestamp.stp (gettimeofday_ns): New function (gettimeofday_us, gettimeofday_ms, gettimeofday_s): Use gettimeofday_ns as the base unit. testsuite/ * buildok/timestamp.stp: add gettimeofday_ns test. --- stapfuncs.5.in | 3 +++ 1 file changed, 3 insertions(+) (limited to 'stapfuncs.5.in') diff --git a/stapfuncs.5.in b/stapfuncs.5.in index 51cdddd8..bde9729b 100644 --- a/stapfuncs.5.in +++ b/stapfuncs.5.in @@ -90,6 +90,9 @@ Return 1 if string s1 contains string s2, returns 0 otherwise. get_cycles:long () Return the processor cycle counter value, or 0 if unavailable. .TP +gettimeofday_ns:long () +Return the number of nanoseconds since the UNIX epoch. +.TP gettimeofday_us:long () Return the number of microseconds since the UNIX epoch. .TP -- cgit
