Subject: timer_stats slimmed down: using statistics infrastucture
From: Martin Peschke <[EMAIL PROTECTED]>
This patch implements timer_stats based on the statistics infrastructure.
Here is some sample output, which even somewhat
resembles /proc/timer_stats.
(>80 char lines because of symbol names, sorry for line breaks).
It reads:
<statistic name> <basket> <hits> <label>
with label being:
<pid> <task name> <start_fn>(<stop_fn>)
[EMAIL PROTECTED] timer_stats]# cat data
this patch changes the userspace API though, and breaks PowerTOP :(
Though I think it was unfortunate to add the "old" proc API in 2.6.21.
timer_stats is clearly labeled as debug stuff in config help, which is why
debugfs would have been a proper place.
