 |
|
Bonjour,
Je viens d'installer une carte graphique RX570 (Sapphire ITX). Celle-ci semble bien supportée dans l'ensemble.
En revanche, j'ai l'impression que le ventilateur n'est pas contrôlé correctement.
Celui-ci ne tourne pas, pourtant il est indiqué par sensors qu'il tourne :
| Code: | $ cat sensors
[...]
amdgpu-pci-0100
Adapter: PCI adapter
vddgfx: 900.00 mV
Ventilateur GPU: 1426 RPM (min = 0 RPM, max = 3500 RPM)
edge: +54.0°C (crit = +94.0°C, hyst = -273.1°C)
PPT: 22.01 W (cap = 120.00 W)
pwm1: 0%
sclk: 404 MHz
mclk: 2 GHz
|
En fait, les réglages d'origine définissent un PWM toujour trop faible pour déclencher le ventilateur, même au-dessus de 50°C.
J'ai essayé de lancer pwmconfig, il parvient bien à le faire tourner à vitesse maximale (~3600 tr/min indiqué) puis l'arrêter temporairement mais quand je lance un test, rien ne se passe :
| Code: | $ sudo pwmconfig
# pwmconfig version 3.6.2
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
Found the following devices:
hwmon0 is acpitz
hwmon1 is drivetemp
hwmon10 is hid_1e:d8:aa:a4:99:41_battery
hwmon2 is drivetemp
hwmon3 is drivetemp
hwmon4 is drivetemp
hwmon5 is drivetemp
hwmon6 is drivetemp
hwmon7 is coretemp
hwmon8 is it8620
hwmon9 is amdgpu
Found the following PWM controls:
hwmon8/pwm1 current value: 70
hwmon8/pwm1 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n)
hwmon8/pwm2 current value: 70
hwmon8/pwm2 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n)
hwmon8/pwm3 current value: 70
hwmon8/pwm3 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n)
hwmon8/pwm4 current value: 70
hwmon8/pwm4 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n)
hwmon8/pwm5 current value: 0
hwmon8/pwm5 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n)
hwmon9/pwm1 current value: 0
hwmon9/pwm1 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) y
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon8/fan1_input current speed: 604 RPM
hwmon8/fan2_input current speed: 1285 RPM
hwmon8/fan3_input current speed: 437 RPM
hwmon8/fan4_input current speed: 0 ... skipping!
hwmon8/fan5_input current speed: 0 ... skipping!
hwmon9/fan1_input current speed: 3578 RPM
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!
Hit return to continue:
Testing pwm control hwmon9/pwm1 ...
hwmon8/fan1_input ... speed was 604 now 607
no correlation
hwmon8/fan2_input ... speed was 1285 now 1225
no correlation
hwmon8/fan3_input ... speed was 437 now 436
no correlation
hwmon9/fan1_input ... speed was 3578 now 3116
no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon9/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)
Did you see/hear a fan stopping during the above test (n)? y
Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)?
What should be the path to your fancontrol config file (/etc/fancontrol)?
Loading configuration from /etc/fancontrol ...
Device path of hwmon5 has changed
Device path of hwmon6 has changed
Device name of hwmon5 has changed
Device name of hwmon6 has changed
Configuration appears to be outdated, discarded
Select fan output to configure, or other action:
1) hwmon9/pwm1 3) Just quit 5) Show configuration
2) Change INTERVAL 4) Save and quit
select (1-n): 1
Devices:
hwmon0 is acpitz

hwmon8/temp3_input 26
hwmon8/temp4_input 27
hwmon8/temp5_input 41

Select a temperature sensor as source for hwmon9/pwm1:

17) hwmon8/temp4_input
18) hwmon8/temp5_input
19) hwmon8/temp6_input
20) hwmon9/temp1_input
21) None (Do not affect this PWM output)
select (1-n): 20
Enter the low temperature (degree C)
below which the fan should spin at minimum speed (20):
Enter the high temperature (degree C)
over which the fan should spin at maximum speed (60): 65
Enter the minimum PWM value (0-255)
at which the fan STOPS spinning (press t to test) (100): t
Now we decrease the PWM value to figure out the lowest usable value.
We will use a slightly greater value as the minimum speed.

Puis plus rien…
Pourriez-vous m'aider à le faire fonctionner correctement SVP ? Peut-être me manque-t-il des drivers ?
Merci beaucoup

J'ai testé manuellement en écrivant ceci, le ventilateur répond bien à ma demande :
| Code: | # cd /sys/class/drm/card0/device/hwmon/hwmon9
# echo 1 > fan1_enable
# echo 100 > pwm1
# echo 150 > pwm1
# echo 200 > pwm1
# echo 255 > pwm1 |
Ce qui m'a permis de créer un /etc/fancontrol qui fonctionne correctement. Après avoir démarré fancontrol, le ventilateur semble géré correctement.
| Code: | $ cat /etc/fancontrol
# Configuration file generated by pwmconfig, changes will be lost
INTERVAL=10
DEVPATH=hwmon9=devices/pci0000:00/0000:00:01.0/0000:01:00.0
DEVNAME=hwmon9=amdgpu
FCTEMPS=hwmon9/pwm1=hwmon9/temp1_input
FCFANS= hwmon9/pwm1=
MINTEMP=hwmon9/pwm1=20
MAXTEMP=hwmon9/pwm1=65
MINSTART=hwmon9/pwm1=150
MINSTOP=hwmon9/pwm1=100
|
Mais comment se fait-il que celui-ci ne fonctionnait pas correctement à l'origine ? En effet, que ce soit pour le ventilo CPU et pour les ventilos du boîtier, ils étaient gérés automatiquement sans avoir besoin ni de configurer ni de démarrer fancontrol... Aussi, quand je cherchais la corrélation entre la vitesse et la valeur PWM, pwmconfig était capable de me faire une courbe de réponse du ventilateur concerné, apparemment il n'y parvient pas pour le GPU.

Aussi, je retrouve maintenant le souci que j'avais eu lors de ma première tentative d'utilisation de fancontrol sous Gentoo : le service crashe lors de la mise en veille du système…
