Jean Delvare 62ed6f484b Fix handling of absolute paths in config 
Reported by Marc Ferland. Make DEVPATH and DEVNAME mandatory only when
using relative paths. Optionally support DEVNAME check when using
absolute paths.

Jean Delvare 7e2b5c3376 pwm: Declare local variables as such 2013-05-01 11:37:47 +00:00
Jean Delvare e46e4e519f pwmconfig: Properly deal with multiple fan control 
When a given PWM output controls more than one fan,
fanactive_min is no longer a space-separated list of numbers, it will
also include items of the form "A+B". The tests in the rest of the
code do not expect that and choke with errors like:

/usr/sbin/pwmconfig: line 926: [: 538+799: integer expression expected
/usr/sbin/pwmconfig: line 952: [: 538+799: integer expression expected

As the only thing we really care about is whether any fan stops
completely when PWM is 0, we can simply record the minimum of the
lowest speed of all affected fans.

Jean Delvare f2b3e95c59 pwmconfig: Drop a stray comment 
fancontrol supports multiple controlled fans for quite some time now.
 2013-05-01 10:30:22 +00:00
Jean Delvare 58ec80bf54 pwmconfig: Raise the detection threshold to 3/4 
Detection threshold of 2/3 of the maximum speed is too low, some fans
will slow down to about that speed so controlled fans may be missed.
Use 3/4 as the threshold to avoid these false negatives.

Jean Delvare 2096d14c18 pwmconfig: Print the initial PWM values 
Print the initial PWM values before letting the user change them. This
should be useful to better understand what happens next, and for user
support in general.

Jean Delvare 501499e834 Wait for fans to return to full speed only once per PWM. In the rare 
case where a given PWM output controls more than one fan, this makes
the script somewhat faster.

Jean Delvare eb40756d74 When looking for pwm/fan correlations, sample all fans before returning 
a given PWM output to full speed. The code used to only sample the first
fan before doing so, so correlation with other fans could be missed.
Problem reported by Charles Pillar. This closes ticket #2380.

Jean Delvare 118a102198 Add a script that provides manual control of the vt1211 PWM outputs. 
This script puts the vt1211 in automatic PWM mode and fools the chip
into believing that there is a temp change to force the PWM outputs to
specified values. This is necessary since the standard manual mode of
the vt1211 doesn't seem to work.
Patch from Juerg Haeflinger.

Jean Delvare 7ca1c39b92 Use the same step values for the MINSTOP test as we do for the detailed 
correlation. That is, 15 above 31 and 2 below 31. This makes more sense
than using 10 all the time, as changes in low PWM values tend to have a
greater effect on fan speeds than changes in high PWM values.
