AMD has updated their Linux Open Source Driver for Vulkan.

v-2022.Q3.5: 2022-9-30 update

The AMD Open Source Driver for Vulkan is an open-source Vulkan driver for Radeon graphics adapters on Linux. 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. Leveraging PAL can help provide a consistent experience across platforms, including support for recently released GPUs and compatibility with AMD developer tools.

Shaders that compose a particular VkPipeline object are compiled as a single entity using the LLVM-Based Pipeline Compiler (LLPC) library. LLPC builds on LLVM's existing shader compilation infrastructure for AMD GPUs to generate code objects compatible with PAL's pipeline ABI. 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.

New feature and improvement

• Update Khronos Vulkan Headers to 1.3.228
• Support extension VK_EXT_depth_clamp_zero_one

• Enable acquire-release barrier
• Enable MSAA decompress with compute engine

Issue fix

• CTS random crash in dEQP-VK.pipeline.pipeline_library.stencil.*.comp_always
• New version CTS failure in dEQP-VK.amd_ray_query.stress
• Corruption in game Control, Detroit:Become Human and SOTR
• Black line corruption in Metal gear Solid The Phantom Pain
• Can’t share pipeline cache among processes
• Corruption with unaligned memory to image copy
• Dota2 crash in game launch
