Sorry for the late reply, I had to take an extended sick leave. I will
take care of sending this fix upstream

Yes, but please test it first. It should apply on-top of a 5.9.3 kernel.
If it works I can send a patch and will Cc you as well as a few other
folks.
Alright, so is this going to make it into an upstream-Kernel?

The GPU seems to have broken ATS, or require driver setup to make ATS
work. Anyhow, ATS is unstable for Linux

Thanks. So I guess the GPU needs a quirk to disable ATS on it. Can you
please send

That is expected. IOMMUv2 depends on ATS support.

Hi Jörg,
I am seeing that amdgpu uses amd_iommu_v2 kernel-module.
