AMDGPU- change Pixel Format, Color Depth, HDMI Link Assurance

[DerCaveman]

Hello!

Is it possible to change these options running Linux?

If I change these settings with AMD Radeon Software Adrenalin Edition are they saved permanently?

TIA,
Heiko.

Does not help nor answer my questions.
I want to change settings relating to the hdmi hardware link.

Nice.
Someone else?

There is a kms attribute to adjust the bit depth in newer kernels, but knobs to change the others are not currently exposed on Linux. The driver selects the optimal settings based on the available bandwidth of the link. If you need this functionality, please consider submitting patches.

Thank you!
Can you explain to me- or give me some links about- how this hardware link negotiation works in AMD graphics cards?

The code in question is in drivers/gpu/drm/amd/display in the kernel.
