Hi Rudolf, I like the added mutex locking. It's a good idea. It sounds like you'll be modifying it a little? Here is the output of the regression test on my machine: # ./w83627ehf_regression.sh * WARNING: This will run your system fans through many possible combinations. There is a possibility your system will overheat. Use this script at your own risk! Mapping fans...setting all PWMs to 100% fan 1 0 RPM: ignored. (Fan not installed?) fan 2 0 RPM: ignored. (Fan not installed?) fan 3 3479 RPM: pwm1 3443 RPM pwm2 3443 RPM pwm3 1654 RPM: connected. Testing fan 3 - pwm3 ... div OK, PWM/DC OK, enable OK test_smartfan1 $1="3" $2="pwm3" , SF1 OK Obviously, I'm right in the middle of building SmartFan 1 testing. It doesn't test that. Everything else works fine. I'm attaching the regression test which is updated for this patch. So, sign me off on it.
