This would mean that a new window might not get pinged for almost 20s, but is that so bad. I think as soon as one has a large amount of windows open (which I have all the time, hell why not use all those virtual desktops :)) this method would be better even if the polling was reduced to 5s. I don't know how feasible this is and I know you have a lot more important things on your plate it's just an idea. > i share your desire to reduce this, though 4/sec is really minimal when you > think about it :) > > I agree. Sony disables the hpet timer in bios and don't put an option in to enable it. I have ~ 100 wakeups/s just caused by the kernel because of this. The Sony bios really sucks. They have a bloody option to enable/disable a bios splash screen, but both hpet and virualization support are disabled and no way of enabling them.

> if the mouse causes 4 interrupts/sec - this probably cause mouse events? > thus x wakeups and then e wakeups to get the events. Nope, the 4/sec are just the usb hcd polling. When I move the mouse, or use the trackpoint, then I get a ton of wakeups. Also, the X wakeups are usually around 1/sec in idle, which implies that it's not pass-through X-events that are triggering it. > 1. something polling - what, i don't know, but you will need to strace > and/or debug and find out. Yeah, I started to use strace and there were a bunch of select() which probably are the cause. There was some mention of a similar problem with WindowMaker, so I'll look into that patch to see what was done to eliminate those wakeups. > i share your desire to reduce this, though 4/sec is really minimal when you > think about it :) It remains to be determined if it makes any real difference, but so far powertop has been pretty effective at reducing the power consumption of my thinkpad, so we'll see...

Of > this, e17 is 4/sec, hence it would be nice to find the culprit and (if > possible) remove it. if the mouse causes 4 interrupts/sec - this probably cause mouse events? thus x wakeups and then e wakeups to get the events. those 4 could be: 1. something polling - what, i don't know, but you will need to strace and/or debug and find out. as already pointed out some modules like to poll - but most of them its in the 1 per second or multiple seconds between polls (except cpufreq. 2. it could be the result of an x client changing a property etc etc. like a titlebar etc. see #1 - need to debug. 3. every 10 secs e pings x clients to see if they are alive if they say they do the netwm ping protocol, but if you have enough windows these pings won't happen at the same time so they will be spread out based on when the window came up. i share your desire to reduce this, though 4/sec is really minimal when you think about it :) > Regards, > > Alec > > > > > - > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.

True, the ipw2100 and the usb mouse cause ~4/sec each and prevent the kernel from reaching C3. With both of these gone and NoDRI for the radeon driver, I can get the kernel into C3 state most of the time with ~6-8 wakeups/sec.

I'm not sure how low you can go, since I can't see less than 61 wakes from the radeon driver, but with e17 idle in xorg, I get 99% of the time in C3. On my system, there are a lot of things waking below e17 which quickly adds beyond the 2-5 polls/sec I get from e, giving a much less marginal benefit. --Kent - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
