With the "Sienna Cichlid" and "Navy Flounder" open-source driver support as what appear to be the first "Navi 2" GPUs and the first of the "GFX10.3" generation on the graphics engine side there is the initial kernel support with Linux 5.9 and the initial Mesa support for 20.2. That Mesa support has been focused on RadeonSI as the official OpenGL driver as well as Mesa's RADV driver as the Radeon Vulkan driver in-tree but not officially supported by AMD. That RADV support is currently un-tested. Both drivers currently depend upon the "AMDGPU" back-end found in the forthcoming LLVM 11.0 with its initial GFX10.3 support. But now on the RADV driver side there is preliminary GFX10.3 bits landing for the popular "ACO" back-end...

Switching from the "Radeon" to "AMDGPU" kernel driver on Linux is possible for Radeon GCN 1.0/1.1 era graphics cards and doing so can mean slight performance benefits, the ability to run the AMDVLK or RADV Vulkan drivers, and simply making use of this better maintained driver. But having these original GCN graphics cards default to the modern AMDGPU driver appears held up by the lack of analog video output support with that driver...

The Linux kernel work for making use of the x86_64 FSGSBASE instruction since Intel Ivy Bridge and since then AMD CPUs also is set to finally land with the in-development Linux 5.9 kernel. The FSGSBASE support has the possibility of helping Intel/AMD CPU performance especially in areas like context switching that had been hurt badly by Spectre/Meltdown and other CPU vulnerability mitigations largely on the Intel side...
