Tool to Control Fan - fanctl

[Luke]

Sorry, I wasn't clear. I want the fan to activate first when the SOC reaches 60*C and I want it to work continually at a temperature of 70*C.
I set the values accordingly in the config:

Code:

       -- Max Temperature Allowed for adjusting fan pwm( On this threshold, and above, fan is always on MaxValue )
       MAX_CONTINUOUS_THERMAL_TEMP     = 70,
       -- Min Temperature  threshold to activate/deactivate Fan
       MIN_CONTINUOUS_THERMAL_TEMP     = 60,

I checked with armbianmonitor that the SOC (which isn't really doing anything at the moment) hovers around ~45*C (max).
Despite this, the fan powers on for approx 2 seconds every minute or two.

I'll monitor whats happening using ats -t

Try, point 3) and 4) on my last comment,

Ans show at least point 3)
ats -t , with the service running

I noticed in the past that, kernels above 4.4.138-1097, do some interference in pwm.
I don't know if that could be the case here..

One way of testing it,
Would be stopping ats service and monitor pwm..
Something like:

Code:

while true;do pwm=$( cat /sys/devices/platform/pwm-fan/hwmon/hwmon0/pwm1);if [ ${pwm} -ne 0 ];then echo "--->${pwm}"; fi; done

 
In this way, you can sort out if pwm automatically activates..

Hello Luke,
I think I understood what you were talking about.. 

I reproduced that behaviour..
stopping ats,
then running ats in test mode..

Code:

root@rockpro64:~# ats -t
info:'SYSTEM' Table
info:    'BOARD' Table
info:        'NAME' = ROCKPRO64
info:        'CPU'  = RK3399
info:    'THERMAL0_CTL' = /sys/class/thermal/thermal_zone0/temp
info:    'THERMAL1_CTL' = /sys/class/thermal/thermal_zone1/temp
info:    'PWM_CTL'      = /sys/class/hwmon/hwmon0/pwm1
warn:    'MAX_CONTINUOUS_THERMAL_TEMP' outside range] -20, 70 [
        'MAX_CONTINUOUS_THERMAL_TEMP' = 60
info:    'MIN_CONTINUOUS_THERMAL_TEMP' = 60

ATS, has hard-limits for temps..
When you configure it to:

Code:

      -- Max Temperature Allowed for adjusting fan pwm( On this threshold, and above, fan is always on MaxValue )
      MAX_CONTINUOUS_THERMAL_TEMP     = 70,
      -- Min Temperature  threshold to activate/deactivate Fan
      MIN_CONTINUOUS_THERMAL_TEMP     = 60,

You are hitting the higher hard limit range: ] -20, 70 [
So Ats warns you,
And corrects 'MAX_CONTINUOUS_THERMAL_TEMP' to 60C

In this situation you end with higher and lower trigger points equal..
Without code changes, the Closest you can get in /etc/ats.conf would be:

Code:

      -- Max Temperature Allowed for adjusting fan pwm( On this threshold, and above, fan is always on MaxValue )
      MAX_CONTINUOUS_THERMAL_TEMP     = 69,
      -- Min Temperature  threshold to activate/deactivate Fan
      MIN_CONTINUOUS_THERMAL_TEMP     = 60,

An output in test mode:

Code:

root@rockpro64:~# ats -t
info:'SYSTEM' Table
info:    'BOARD' Table
info:        'NAME' = ROCKPRO64
info:        'CPU'  = RK3399
info:    'THERMAL0_CTL' = /sys/class/thermal/thermal_zone0/temp
info:    'THERMAL1_CTL' = /sys/class/thermal/thermal_zone1/temp
info:    'PWM_CTL'      = /sys/class/hwmon/hwmon0/pwm1
info:    'MAX_CONTINUOUS_THERMAL_TEMP' = 69
info:    'MIN_CONTINUOUS_THERMAL_TEMP' = 60
info:    'MAX_PWM' = 255
info:    'MIN_PWM' = 40
info:    'ALWAYS_ON' = false
info:    'PROFILE_NAME' = profile0
info:    'PROFILE'      = 0
info:'Pratio' timers
info:    'Pratio[ -20 - 60 [' = 0
info:    'Pratio[ 60 ]'       = 40
info:    'Pratio[ 61 ]'       = 63
info:    'Pratio[ 62 ]'       = 87
info:    'Pratio[ 63 ]'       = 111
info:    'Pratio[ 64 ]'       = 135
info:    'Pratio[ 65 ]'       = 159
info:    'Pratio[ 66 ]'       = 183
info:    'Pratio[ 67 ]'       = 207
info:    'Pratio[ 68 ]'       = 231
info:    'Pratio[ 69 ]'       = 255
info:    'Pratio[ 69 - 70 ['  = 255
Stop ATS Service first [ service ats stop ]..

No more warnings, and so no internal adjustments..

But even So, I could reproduce your report:

Code:

--------------------
Running for[ seconds ]................ 0
CPU Temperature[ max 70 °C ].......... 58
GPU Temperature[ max 70 °C ].......... 49
Fan PWM Duty Cycle value[ 0 - 255 ]... 0
--------------------
Stopping for[ seconds ]............... 120
CPU Temperature[ max 70 °C ].......... 58
GPU Temperature[ max 70 °C ].......... 49
Fan PWM Duty Cycle value[ 0 - 255 ]... 0
--------------------

I will look into the code, and check it..
The power is activated in 2 phases, probably the first one is running, on this conditions..

Thanks for reporting that!

[Luke]

Many thanks tuxd3v ! I'll retest with the values you suggested today and let you know how it goes

[edit] with your suggested values set in /etc/ats.conf

I am seeing same behaviour, the fan engages for a split second then spools back down. The log below is from ~4 min of ats -t running.

Hello Luke,
Yes, I remember that at the time,
I wanted to make a optimisation , and that reflected in the first stage start outside active window too briefly..

I am in a project now, but has promised I will look into it, and correct it   
I suspect that for that, I will loose the optimisation I have done before( ..its around 0.0001% CPU time), but maybe I could improve, in another places to gain it back 

Thanks for you post on this subject,
I confess, that with time I have forgotten it 

Best Regards

Hello Farley56,
What I recommend, is to go always...to Stable Version.. 

1) Please, remove the version you have installed..

First stop the running service:

Code:

service ats stop

Then remove version installed:

Code:

luarocks remove ats

2) Install Again:

Code:

luarocks build https://raw.githubusercontent.com/tuxd3v/ats/master/ats-master-0.rockspec

2.1) This is the full output of a installation, using the master branch( Method 1. )

Hello,
Try to run this:

Code:

which lua

Probably you don't have the symbolic link, bellow, created.. 
Create it with:

Code:

ln -s /usr/bin/lua5.3 /usr/bin/lua

And install again,it should work 

[Farley56]

Thanks for the suggestions.
1. which lua returned error.
