AMD has updated their Linux Open Source Driver for Vulkan.

v-2022.Q3.3: 2022-8-18 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 1.3.223
* Add the support for IB2 dump to PAL command dumper
* Performance tuning for Rage2, Rainbow Six: Extraction/Siege and Totalwar: WarhammerIII

Issue fix

* Robustness issue for VK_EXT_private_data
