Hello.
I want to get GPU fan speed on Ubuntu 20.04 via sysfs interface.
There is a Linux kernel documentation - https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
So I'm executing the next command to get fan input value:
cat /sys/class/drm/card0/device/hwmon/hwmon3/fan1_input
I've tried different versions of drivers: 20.30, 20.40, 20.45, 20.50, but got the same result 0.
At the same time this command works well for RX 470/570 GPUs, but it does not work with Navi RX5500XT GPU. It always return 0.
Thanks
