My best guess is that the status script is causing the problem. Try disabling the 'Action status' bit of wmiirc. I'm guessing that one or more of of date(1), uptime(1), or wmiirc(1) aren't making the buffer cache. If stopping the status script solves your problem, try sticking wmiir on a ram disk (it's statically linked by default), and ideally finding a statically linked date(1) and uptime(1) to do the same. -- Kris Maglione Question with boldness even the existence of God; because if there be one, He must approve the homage of Reason rather than that of blindfolded Fear. --Thomas Jefferson

Have you tried without any status > scripts running? you were right. ran it with only /bin/true in wmiirc and got less then 10 wakeups with only rxvt and powertop running. i'm using standard wmiirc/wmii.ssh that comes with wmii devel. time to dig into those scripts to finaly learn how it works. thanks mk

I can't really think of anything wmii would do to trigger wakeups, except perhaps in the rc code. Have you tried without any status scripts running? -- Kris Maglione Beware of "the real world".

[wmii] wmii hg devel, increased cpu wakeups-from-idle
Hi. I've migrated from the "stable" wmii(20080530 or similar) to development version and I've noticed increased wakeups-from-idle when measured with powertop. It used to be something like 13 wakeups, now its 40+. I've tested simple X(without any wm) with xterm and I get 2 wakeups in this way, so I guess it's not a problem with the rest of my system. Also the weird thing is, powertop doesn't show any processes with many wakeups. the largest event is hrtimer_start with 3.5 wakeups. If I sum up the rest of what powertop shows I get something around 6 wakeups so there must be either hundreds of little wakeups or there is something seriously wrong. Is anyone else experiencing similar problem? Could this really be related to wmii or is it something else? thanks mk
