[Issue]: Can not set fan speed on Radeon Pro W7900

[AbdullahMPrograms]

Problem Description

I am currently not able to set fan speeds for my W7900 card using the echo commands:

echo 0 50 40 > fan_curve 
echo 1 55 45 > fan_curve
echo 2 60 50 > fan_curve
echo 3 65 55 > fan_curve
echo 4 70 60 > fan_curve

on my system this shows:

$ cat fan_curve
OD_FAN_CURVE:
0: 0C 0%
1: 0C 0%
2: 0C 0%
3: 0C 0%
4: 0C 0%
OD_RANGE:
FAN_CURVE(hotspot temp): 0C 0C
FAN_CURVE(fan speed): 0% 0%

$ echo 0 50 40 > fan_curve 
bash: fan_curve: Permission denied

$ echo 0 50 40 | sudo tee fan_curve
0 50 40
tee: fan_curve: Invalid argument

$ echo "manual" | sudo tee /sys/class/drm/card0/device/power_dpm_force_performance_level  
manual

$ cd /sys/class/drm/card0/device/gpu_od/fan_ctrl

$ echo 0 50 40 | sudo tee fan_curve
0 50 40
tee: fan_curve: Invalid argument

The ppfeature mask is set through kernel parameters like so:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.ras_enable=0 amdgpu.ppfeaturemask=0xfff7ffff"

@tcgu-amd I'll continue our debugging here so that we can better track its status

bump, issue still unsolved

Hi @AbdullahMPrograms, thanks for bumping! I think at this point it is possible that fan curve control is intentionally locked on the firmware level for the pro cards. Might want to check with the fw guys to know for sure...
