Tuxclocker does nothing on my RX Vega

[mauvray]

On a fresh arch install, with the proper config, tuxclocker does not change anything for my GPU, whether it'd be power limit or pstates contrary to LACT. I don't see any error either in journalctl.

What steps exactly lead to this "not working" state? Have you pressed 'Apply changes'?

[mauvray]

Yes, when I click on 'Apply changes', I get the small green highlight, but if I look from sysfs, rocm-smi or lact, nothing changes.

[Lurkki14]

Does cat /sys/class/drm/card*/device/hwmon/hwmon*/power1_cap look different after changing power limit in tuxclocker?

And what about cat /sys/class/drm/card*/device/pp_od_clk_voltage with the pstates?

[mauvray]

Nothing changes, neither for /sys/class/drm/card1/device/hwmon/hwmon1/power1_cap nor /sys/class/drm/card1/device/pp_od_clk_voltage

[Lurkki14]

And what do those files look like normally?

[mauvray]

Those contain values that I can set by hand without tuxclocker or with lact.

[Lurkki14]

By that I mean, can you post the contents of the files here

Hi,

Tuxclocker has no effect on my 6900 XT.

This is on Arch Linux and Tuxclocker has been installed via AUR.

The UI shows as if the value had changed, but no values actually change (as shown my sensors command or looking at the nodes under /sys/class/drm/card1/device/hwmon/hwmon1. I can change power1_cap manually, but not via Tuxclocker.
