Can't use my Radeon RX 5700 XT with Blender on Linux

Hello.

The title sums up the problem. I tried to install OpenCL and use my RX 5700 XT to make 3D renders with my graphic card, but even though Blender does run well, there's no way I could connect it to my GPU.
Apparently, renders are made using my CPU (not the best way to use it I guess) and that also explains why they're so long to be made.

I saw an article talking about an improved management of AMD GPUs in Blender 3.0, the thing is that now we're at 3.1.2 and I still can't use my GPU, either with HIP or OpenCL.
Any solution ?

Blender has removed OpenCL support. In the future it will support HIP with ROCm but in any case your (and mine) video card only has partial ROCm support. Although criticized, it was a mistake to remove OpenCL.

I read somewhere that HIP is Windows-only and there's no info about it being supported on Linux. Any idea aout that?

It got added in the just released 3.2 version: https://wiki.blender.org/wiki/Reference … _Rendering but it seems there's something missing from the Arch package (I'd assume some build flags/build deps): https://bugs.archlinux.org/task/75011

The Blender package seems like it has been repaired now, but I still got this problem : https://i.imgur.com/d8kZOXw.png

Kinda problematic.

If you use the package from the repos, no it hasn't, try the upstream binary build.

To me (RX 5700XT) with the upstream binary build everything is recognized without problems, but the rendering still works with just the CPU without using the GPU.

Same. Blender still doesn't recognize my graphic card and pretends there's none, stating there is a need for up-to-date AMD drivers blablablah...
I guess I'm gonna wait again.
