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.

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
