AMDVLK is the AMD official open-source Vulkan driver for Linux systems.

• AMDVLK is derived from the same sources as their Windows/Linux proprietary driver but built against the open-source AMDGPU LLVM shader compiler rather than AMDs proprietary shader compiler.

AMDVLK comes with something AMD calls “AMD switchable graphics layer” in the form of a implicit layer library and configuration file in /etc/vulkan/implicit_layer.d/amd_icd64.json.

• This lets you choose what Vulkan driver to use by setting AMD_VULKAN_ICD to AMDVLK or RADV if you choose to install the AMDVLK driver side-by-side with the Mesa RADV Vulkan driver.
