There is a bunch of entirely FOSS drivers for AMD Radeon cards:
Kernel drivers:
radeon: for older cards before GCN1.2 (kernel/drivers/gpu/drm/radeon)
amdgpu: for the new cards since GCN1.2 (kernel/drivers/gpu/drm/amd/amdgpu)
Userspace drivers:
radeonsi: for almost all cards in the last decade
(mesa/src/gallium/drivers/radeonsi)
r600: for the ones before (mesa/src/gallium/drivers/r600)
Vulkan drivers:
RADV: written by the community (RedHat etc.), because AMD initially didn't make
their Vulkan
userspace FOSS (mesa/src/amd/vulkan)
AMDVLK: AMDs Vulkan driver released as FOSS
(https://github.com/GPUOpen-Drivers/AMDVLK)
So your FOSS driver would consist of amdgpu + radeonsi + radv and is in almost
all cases the
best choice (performance, stability etc).
Then there was always a propriatary driver by AMD nowadays it's called "Radeon
Software for Linux",
which bundles also free software like AMDVLK and ROCm. Other names before were
"AMDGPU-PRO",
"AMD Catalyst" and "fglrx"...
I hope it's now less confusing then before :P
