That means your hardware or drivers don't support this feature. If you know the hardware does, then the driver is to blame.

It's AMDGPU on RX 580 - how to check whether the support is there or not? Any ideas where to play with stuff to make it work?

amdgpu has no support for this yet: https://gitlab.freedesktop.org/drm/amd/-/issues/476
