Same > for PWM outputs. 1) I was reading my mainboard manual and I found that there is a third fan connector (1 processor fan and 2 chassis fans). I have just two: 1 processor and 1 chassis). I confirmed at the mainboard and the third connector is really there. I can't test it for now. 2)Sorry, I didn't understand about PWM outputs. Sorry. :-| > This is now fixed in patch tagged beta1: > http://khali.linux-fr.org/devel/i2c/linux-2.6/linux-2.6.8-rc2-i2c-smsc47m1-beta1.diff > > Please test and confirm that both of you now have fan 1 and 2 > working, and two pwm file sets as well (whether they have an actual > effect on fans is yet another matter). > > (You can revert the first patch using "patch -R" before applying > this one, so that you won't waste your time getting a fresh new > tree.) I did patch -p1 -R. I applied the new one. Applied and compiled fine. Please, take a look at probs2.txt attached. > Thanks a lot for testing my code. Thanks a lot for coding it. :-) > Among things that can be done to test the driver more actively: > > 1* Change fan limits in /etc/sensors.conf, run "sensors -s" and > check that the limits have been set properly. Ditto for divisors. As you can see at probs2.txt, I tried some values and there are diffs between them. (sensors.conf and sensors output) > 2* Change the fan limits through sysfs directly. Testing of corner > cases is welcome (large values, negative values, zero). Ditto for > divisors. I tried to put values in fan1_min. It didn't accepted values less than 1299 and treated it as 1300. I tried negative values and it didn't accept it. (if you "cat fan1_min" or use sensors command, the output is the same: 1300) (see probs2.txt also) > 3* Play with PWM (enable/disable, change speed). Be careful not to > stop your fans completely, systems usually don't like that much. As I said, I am not using PWM (power management?), so I don't know how to try this. Sorry. Oh, I am using gkrellm and I can get fans there too. (both) :-) If you need more information, please just tell me. > Thanks again. Thanks again, too. :-) Cheers, Freitas -------------- next part -------------- A non-text attachment was scrubbed...
