My AMD Radeon RX 6700 XT is not being used by Wayland or any applications.
My main goal is to run Davinci Resolve (OpenCL) using an eGPU on my thunderbolt laptop, and I’m currently using Minecraft as a “test application” alongside command line tools such as lspci and glxinfo to determine if my GPU is working at all.
After weeks of trying other guides, the furthest I got was with AMDGPU drivers, the kernel args “radeon.cik_support=0 amdgpu.cik_support=1”, and importing secure boot keys for DKMS by running mokutil --import /root/mok.der. I was able to open Resolve and it saw my GPU, but pictures and videos wouldn’t render. Minecraft used the GPU seemingly without issue. Minecraft no longer used and Resolve no longer detected my GPU after a reboot, and I had many DKMS problems.
My setup
OS: Fedora 37
Kernel: 6.0.12-300.fc37.x86_64
Kernel args: ro rootflags=subvol=root rd.luks.uuid=luks-x-x-x-x-x rhgb quiet module_blacklist=hid_sensor_hub nvme.noacpi=1
Window manager: Wayland
Device: Framework Laptop 12th gen (thunderbolt 4)
Secure boot: Enabled
eGPU: Akitio Node Titan (thunderbolt 3)
GPU: Gigabyte (AMD) Radeon RX 6700 XT
I’ve tried every guide I could find over the past few weeks, but to no avail. Any ideas or suggestions would be really appreciated. Please find below some of my troubleshooting:

Test A2 analysis
It is interesting that when using “Test procedure 2” where I connect my eGPU at the Gnome lockscreen instead of before booting, clinfo is able to detect 1 device (my AMD GPU), where as when using “Test procedure 1”, clinfo does not detect any devices.
