Bug: fan spinning on max pwm even when temperature is low enough #27

Closed tandy-1000 closed 3 years ago

tandy-1000 commented 3 years ago

I notice sometimes that the temperature is around 34 degrees but the fan is stuck spinning at 255 pwm. If I restart the ATS service, the pwm goes down to 0 because of the low temperature.

Hardware: RockPro64 dietpi with ats master

Please let me know if you need any more information

I have the same problem, fan keeps spinning 24/7.

Hello , Check if the temperature entries in the /sys is correct, Wha is the output of this?

find /sys -name temp\*

hello Morpheus2018, if you do:

cat /sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input
cat /sys/devices/virtual/thermal/thermal_zone1/hwmon1/temp1_input
cat /sys/devices/virtual/thermal/thermal_zone0/temp
cat /sys/devices/virtual/thermal/thermal_zone1/temp

does the temperature is low? this are the places you should have in '/etc/ats,conf'` as 'THERMAL{0,1}_CTL'

but looking at your 'ats -t' you have: info: 'PWM_CTL' = ERROR

What is the output of this?

find /sys -name pwm\*

You should have a valid PWM entry in '/etc/ats.conf' as PWM_CTL.. For what I see ats can't set pwm because its in error :/

Morpheus2018 commented 3 years ago

if i do:

cat /sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input
45000
cat /sys/devices/virtual/thermal/thermal_zone1/hwmon1/temp1_input
43888
cat /sys/devices/virtual/thermal/thermal_zone0/temp
45000
cat /sys/devices/virtual/thermal/thermal_zone1/temp

the numbers are changing too!

What is the output of this?

find /sys -name pwm\*

output is... ~$ sudo find /sys -name pwm* /sys/kernel/debug/tracing/events/pwm /sys/kernel/debug/tracing/events/pwm/pwm_apply /sys/kernel/debug/tracing/events/pwm/pwm_get /sys/kernel/debug/pwm /sys/kernel/debug/regulator/vcc12v_dcin/pwm-fan-fan /sys/class/pwm /sys/class/pwm/pwmchip2 /sys/class/pwm/pwmchip0 /sys/class/pwm/pwmchip1 /sys/devices/platform/ff420020.pwm/pwm /sys/devices/platform/ff420020.pwm/pwm/pwmchip2 /sys/devices/platform/ff420010.pwm/pwm /sys/devices/platform/ff420010.pwm/pwm/pwmchip1 /sys/devices/platform/ff420000.pwm/pwm /sys/devices/platform/ff420000.pwm/pwm/pwmchip0 /sys/devices/platform/pwm-fan /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1 /sys/devices/platform/vcc12v-dcin/regulator/regulator.1/pwm-fan-fan /sys/bus/platform/devices/pwm-fan /sys/bus/platform/drivers/pwm-clock /sys/bus/platform/drivers/pwm-fan /sys/bus/platform/drivers/pwm-fan/pwm-fan /sys/bus/platform/drivers/pwm-regulator /sys/firmware/devicetree/base/pwm@ff420020 /sys/firmware/devicetree/base/pwm@ff420010 /sys/firmware/devicetree/base/pwm@ff420000 /sys/firmware/devicetree/base/pinctrl/pwm1 /sys/firmware/devicetree/base/pinctrl/pwm1/pwm1-pin /sys/firmware/devicetree/base/pinctrl/pwm1/pwm1-pin-pull-down /sys/firmware/devicetree/base/pinctrl/pwm3a /sys/firmware/devicetree/base/pinctrl/pwm3a/pwm3a-pin /sys/firmware/devicetree/base/pinctrl/pwm2 /sys/firmware/devicetree/base/pinctrl/pwm2/pwm2-pin /sys/firmware/devicetree/base/pinctrl/pwm2/pwm2-pin-pull-down /sys/firmware/devicetree/base/pinctrl/pwm0 /sys/firmware/devicetree/base/pinctrl/pwm0/pwm0-pin-pull-down /sys/firmware/devicetree/base/pinctrl/pwm0/pwm0-pin /sys/firmware/devicetree/base/pinctrl/pwm3b /sys/firmware/devicetree/base/pinctrl/pwm3b/pwm3b-pin /sys/firmware/devicetree/base/vdd-log/pwms /sys/firmware/devicetree/base/pwm-fan /sys/firmware/devicetree/base/pwm-fan/pwms /sys/firmware/devicetree/base/symbols/pwm3a_pin /sys/firmware/devicetree/base/symbols/pwm0_pin /sys/firmware/devicetree/base/symbols/pwm3 /sys/firmware/devicetree/base/symbols/pwm3b_pin /sys/firmware/devicetree/base/symbols/pwm1 /sys/firmware/devicetree/base/symbols/pwm1_pin /sys/firmware/devicetree/base/symbols/pwm1_pin_pull_down /sys/firmware/devicetree/base/symbols/pwm2_pin /sys/firmware/devicetree/base/symbols/pwm2 /sys/firmware/devicetree/base/symbols/pwm2_pin_pull_down /sys/firmware/devicetree/base/symbols/pwm0 /sys/firmware/devicetree/base/symbols/pwm0_pin_pull_down /sys/firmware/devicetree/base/pwm@ff420030 /sys/module/pwm_fan

The only way to slow the fan down is for me like this: 


sudo find /sys -name pwm1 | grep hwmon
/sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1
cat /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1
255
sudo nano /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1
cat /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1

hello, For what I see, In '/etc/ats.conf' use for PWM_CTL, the '/sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1' :)

And your problem should be fixed :)

now seems to be working again! why has / hwmon3 / changed automatically? For me it's solved first, thank you very much!

hello Morpheus2018, Nice you succeed :)

yeah, the Mainline kernel is a bit dynamic,,on reboot it sometimes change the paths :/ that's why we have in '/etc/ats.conf' so many options .. for control files in sysfs.. When ATS starts, it will check all links and see what of them are valid, and will stay with valid ones :)
