AMD’s Open Source Vulkan Graphics Drivers Now Enable Ray Tracing
|
||||
======
|
||||
*Linux users of RDNA 2 GPUs can use the AMDVLK GPUOpen open source Vulkan driver from AMD.*
|
||||
|
||||
The AMDVLK GPUOpen graphics driver for its Radeon RX 6000 GPUs has improved support for 64-bit ray tracing over the past week. This covers RDNA 2 graphics-enabled APUs as well as desktop/mobility GPUs. Hardware ray tracing is now supported by all AMD Vulkan drivers on all platforms, including Mesa3D RADV, AMDVLK GPUOpen, and AMDGPU-PRO.
|
||||
|
||||
The foundation of the GPURT library is a C++ interface. Depending on its usage and dependencies, the public interface is split up into various header files. Users can learn more on the official GitHub website, which also includes a breakdown of the structure, about the RDNA 2 GPU Ray Tracing Library (GPURT). The most recent AMDVLK GPUOpen v-2022.Q3.4 information is provided below:
|
||||
|
||||
**Updates and new features**
|
||||
|
||||
* Expand Navi2x’s capability for 64-bit ray tracing.
|
||||
* Upgrade Vulkan Headers to version 1.3.225
|
||||
* Game performance optimization, including For Honor and Ashes of the Singularity
|
||||
|
||||
**Issues resolved so far**
|
||||
|
||||
* The dEQP-VK.api.copy and blit..resolve image.whole copy before resolving transfer has a new version CTS failure.
|
||||
* dEQP-VK.pipeline.creation cache control has a CTS warning.
|
||||
* Firefox corruption on Ubuntu 22.04
|
||||
* VulkanInfo crash with pipeline cache deactivated
|
||||
* RGP test kit failure on RX 6800
|
||||
|
||||
The new improvements include the GPU Ray Tracing Library, or GPURT, which will include the construct and sort processing for the Bounding Volume Hierarchy (BVH) seen in ray tracing utilising shaders like HLSL. This library will provide a standard library to improve graphics rendering and introduce more uniformity. DirectX 12 DXR will also work with the new library.
|
||||
|
||||
The description of the GPU Ray Tracing (GPURT) library reads as “a static library (source deliverable) that provides ray tracing-related functionalities for AMD drivers supporting DXR (DirectX 12) and the Vulkan® RT API.” The company’s Platform Abstraction Library is used to build the library (PAL).
|
||||
|
||||
The installation instructions for the most recent AMDVLK GPUOpen v-2022.Q3.4 upgrade are available here for users. Users should back up any relevant data before updating any software, hardware, or drivers in order to avoid losing crucial files. A lot of work has been put into getting the most recent Linux driver ready for AMD, Intel, and NVIDIA technologies, which were all launched in the first quarter of this year.

AMD 的开源图形驱动程序 Vulkan现在支持光线追踪
|
||||
======
|
||||
*RDNA 2 GPU 的 Linux 用户可以使用 AMD 的 AMDVLK GPUOpen 开源 Vulkan 驱动程序。*
|
||||
|
||||
用于 Radeon RX 6000 GPU 的 AMDVLK GPUOpen 图形驱动程序在过去一周改进了对 64 位光线追踪的支持。这涵盖了支持 RDNA 2 图形的 APU 以及桌面/移动 GPU。所有平台上的所有 AMD Vulkan 驱动程序现在都支持硬件光线追踪，包括 Mesa3D RADV、AMDVLK GPUOpen 和 AMDGPU-PRO。
|
||||
|
||||
GPURT 库的基础是 C++ 接口。根据其用法和依赖关系，公共接口被拆分为各种头文件。用户可以在官方 GitHub 网站上了解更多信息，该网站还包括结构细分，关于 RDNA 2 GPU 光线追踪库 (GPURT)。最新的 AMDVLK GPUOpen v-2022.Q3.4 信息如下：
|
||||
|
||||
**更新和新功能**
|
||||
|
||||
- 扩展 Navi2x 的 64 位光线追踪功能。
|
||||
- 将 Vulkan 标头升级到版本 1.3.225
|
||||
- 游戏性能优化，包括《荣耀战魂》和《奇点灰烬》
|
||||
|
||||
**目前解决的问题**
|
||||
|
||||
- 解析传输前的dEQP-VK.api.copy和blit..resolve image.whole copy有新版本CTS失败。
|
||||
- dEQP-VK.pipeline.creation 缓存控件有一个 CTS 警告。
|
||||
- Ubuntu 22.04 上的 Firefox 损坏
|
||||
- VulkanInfo 崩溃，管道缓存已停用
|
||||
- RX 6800 上的 RGP 测试套件故障
|
||||
|
||||
新的改进包括 GPU 光线追踪库或 GPURT，它将包括使用 HLSL 等着色器在光线追踪中看到的边界体积层次 (BVH) 的构造和排序处理。这个库将提供一个标准库来改进图形渲染并引入更多的统一性。DirectX 12 DXR 也将与新库一起使用。
|
||||
|
||||
GPU 光线追踪 (GPURT) 库的描述为“一个静态库（可交付源代码），为支持 DXR (DirectX 12) 和 Vulkan® RT API 的 AMD 驱动程序提供与光线追踪相关的功能。” 该公司的平台抽象库用于构建库（PAL）。

||||
用户可在此处获得最新 AMDVLK GPUOpen v-2022.Q3.4 升级的安装说明。用户在更新任何软件、硬件或驱动程序之前应备份所有相关数据，以免丢失重要文件。为了让最新的 Linux 驱动程序为 AMD、Intel 和 NVIDIA 技术做好准备，已经投入了大量工作，这些技术都是在今年第一季度推出的。
