Overview
This task is to enable GPU denoising on AMD GPUs. We have a denoising library (https://github.com/GPUOpen-LibrariesAndSDKs/RadeonImageFilter) publically available which operates similarly to OIDN, Optix, etc. We would like to use this to enable faster GPU denoising for users on AMD hardware. It should be noted, this library actually works on other GPUs and CPU (the latter via OIDN) but on Nvidia GPUs, the Optix denoiser will most likely be more optimal.
GPL compliance
We offer the library free under a permissive Apache2 license at the link above. However, it is not open source. A shortly upcoming version of the AMD driver on windows will include this RIF library. Thus we propose to use it similarly as Optix, as a closed source "system device" library exception to the GPL.
Code design
We added a new denoiser type, AMD Radeon Image Filter, with similar options to Optix Denoising to enable usage.
Patch coming soon.

Looking for feedback on licensing approach. But as we see it, this is directly in line with the current usage of Optix Denoising library.

Would this work with existing AMD GPUs, such as the 5000 series?

Hello,
Thank you.

I think we can close this now that there is OpenImageDenoise with HIP support.
