   This package provide a script for install amdgpu: amdgpu-install, and 2 repos: amdgpu.repo and rocm.repo.

The purpose of step 4 and 5 is use a available version by changing baseurl. This article may be outdated, so you may want to open the baseurl (ignore the part from $amdgpudistro) on browser to see which version is available.

4. Edit baseurl in /etc/yum.repos.d/amdgpu*.repo, change $amdgpudistro to 9.4:

   $ sed -i -e "s#\$amdgpudistro#9.4#g" /etc/yum.repos.d/amdgpu*.repo

5. Change rocm repo version to 5.3 if it is 5.2, because version 5.2 doesn't exist anymore:

   $ sudo sed -i -e "s#5\.2#5.3#g" /etc/yum.repos.d/rocm.repo

6. Enable rocm repo

   $ sudo dnf config-manager --enable rocm

7. Install hip and opencl

   $ amdgpu-install --no-dkms --usecase=hip,opencl

8. Done. Now you can open Blender (>= 3.2) to check if HiP is available in Cycle.
