The driver can only work with firmware of ME feature version >= 25 (you can check the version with command "sudo cat /sys/kernel/debug/dri/0/amdgpu_firmware_info").CTS may hang in VK.synchronization.internally_synchronized_objects.pipeline_cache_compute with Linux kernel versions lower than 4.13.Optimizations to improve CPU-limited performance.LLPC optimizations to improve GPU-limited performance and compile time.
Hardware performance counter collection through RenderDoc. 
The following features and improvements are planned in future releases (Please refer to Release Notes for update of each release):
Mid-command buffer preemption and SR-IOV virtualization. The AMD Open Source Driver for Vulkan is designed to support the following features: To run the Vulkan driver with AMDGPU upstream driver stack on SI and CI generation GPUs, amdgpu.si_support and amdgpu.cik_support need to be enabled in kernel Feature Support and Performance You may try it out on other distros and versions of your choice. The driver has not been well tested on other distros and versions. The AMD Open Source Driver for Vulkan is designed to support following distros and versions on both the AMDGPU upstream driver stack and the AMDGPU Pro driver stack: The AMD Open Source Driver for Vulkan is designed to support the following AMD GPUs: Notably, AMD's closed-source Vulkan driver currently uses a different pipeline compiler, which is the major difference between AMD's open-source and closed-source Vulkan drivers. LLPC builds on LLVM's existing shader compilation infrastructure for AMD GPUs to generate code objects compatible with PAL's pipeline ABI. Shaders that compose a particular VkPipeline object are compiled as a single entity using the LLVM-Based Pipeline Compiler (LLPC) library. 
Leveraging PAL can help provide a consistent experience across platforms, including support for recently released GPUs and compatibility with AMD developer tools. It is built on top of AMD's Platform Abstraction Library (PAL), a shared component that is designed to encapsulate certain hardware and OS-specific programming details for many of AMD's 3D and compute drivers. The AMD Open Source Driver for Vulkan® is an open-source Vulkan driver for Radeon™ graphics adapters on Linux®.
