Hmm, uptime_proc_show() still uses get_monotonic_boottime(), this should include suspend time? > The second value isn't documented but looking at fs/proc/uptime.c I > think it's idle time? And this cpustat[CPUTIME_IDLE] doesn't match get_idle_time(), I guess it only counts ticks. > Except, if yo uadd up the idle time from all > processors wouldn't you get 4x the uptime on a 4-way SMP system that's > been idle since boot? Yes, looks strange. > Also, is this actual "cpu was on but not doing anything" time, so > doesn't count suspend as idle? I think suspend is not counted as idle. > Confused, I guess the 2nd value is historical, probably you should use /proc/stat.
