RX6800 support

Hello,

I am using a RX 6800 GPU under RHEL 8.3 I installed the amdgpu-pro driver and opencl pro (rocm) [--opencl=rocm,legacy], also Vulkan Pro and mesa.

However, mesa is still 20.1 version (think at FEDORA 33 it is actually already 20.3).
Vulkan driver is not recognized when building UnrealEngine (v26) from source - and opengl is no longer supported for Unreal Engine.

Looks, like either the drivers are to old (but it is official amd release) or there is something odd with my system (but it is RHEL 8.3).

Tried the same stuff before with Fedora 33 and opensource drivers for RX 6800, already build in Kernel 5.10.7. New mesa, LVV11 and rocm4.0 worked well with UnrealEngine, Blender, etc. However, the standard GPU driver did not work with Houdini. Here the amdgpu-pro works.

Can't be the only solution, to have dual boot with Fedora and RHEL8???

Any ideas ? -- much appreciated ..

Thanks
Claus
