By default it adds 1, and a number of points may be transmited in event's parameters. E.g. sched:sched_stat_runtime adds how long process has been running. But this functionality was broken by v2.6.31-rc5-392-gf413cdb and now the event's parameters doesn't affect on a number of points. TP_perf_assign isn't defined, so __perf_count(c) isn't executed and __count is always equal to 1.
