First off, thanks for your contribution to more tolerable sound levels.
However, i cant for the life of me figure out what i should put in the config file. Did i miss where the docs for that format are located?
What does "ty" mean? How do i set another profile than Maximum? Is that even what i should be doing?
Even if i change the "output" values to 0.1 or even 0.0 the resulting speed is over 2000RPM.
Edit: Apparently the key is the "ty: Static" entry, which acts as a "minimum" setting, not allowing the curve to go below it. How was i supposed to know?

5700(XT) cards with custom fan curve on linux via kernel patch + fanctl!

Yes, that was the patch that I did forgot. I saw the commit in the drm next when I was looking for some sdma patchs...
Now I'm waiting for proper OD support. I did flash the 5700 XT 50th anniversary edition BIOS in my 5700 and it work fine except that it somehow killed IOMMU support (temp don't go over 73ºC at 1980Mhz). Once OD will work I will be able to increase the power limit.

But I don't need anymore as I did add the card on my custom loop.
amdgpu-pci-0d00
Adapter: PCI adapter
vddgfx: +0.78 V
fan1: 0 RPM (min = 0 RPM, max = 4950 RPM)
edge: +38.0°C (crit = +118.0°C, hyst = +0.0°C)
(emerg = +80000.0°C)
junction: +39.0°C (crit = +80000.0°C, hyst = +0.0°C)
(emerg = +80000.0°C)
mem: +44.0°C (crit = +80000.0°C, hyst = +0.0°C)
(emerg = +80000.0°C)
power1: 31.00 W (cap = 150.00 W)
Next step : overclocking, did not have time to look at it yet.

From that output, it looks like fanctl is failing to write "1" to the fanX_enable file. Are you using the PwmFan controller or the AmdgpuFan config in fanctl?

Is there is another switch I have to enable before?

5700(XT) cards with custom fan curve on linux via kernel patch + fanctl!
Hey everyone, I don't really know where to post this, but I thought it might be quite useful to people around here, and maybe even Michael.
Since the default fan curve on the 5700/5700XT is quite bad on the reference cards, I wanted to get a custom fan curve working. It required both a bugfix patch for the kernel/amdgpu, and writing a simple fan controller.
You can find my kernel patch (should be on amd-staging-drm-next soon) here: https://lists.freedesktop.org/archiv...ly/037735.html. That patch will make the sysfs interface for the fans work.
My fan controller (fanctl), can be found on GitLab here: https://gitlab.com/mcoffin/fanctl.
Here is a config file I'm using for a very aggressive fan curve on my 5700 XT. It's loud, but you won't be hurting your card while benchmarking! : https://gitlab.com/snippets/1881771.
To run the fan controller (as root for proper permissions), use the following command.
Code:fanctl -c /path/to/fanctl.yml
FWIW, I also noticed that to get my card to use the correct power profile mode, I had to do the following:
Code:echo 1 | sudo tee /sys/class/drm/card0/device/pp_power_profile_mode && echo 0 1 | sudo tee /sys/class/drm/card0/device/pp_dpm_sclk
Cheers, and happy hacking,
