このページでは AMD GPU 用のクローズドソースドライバーについて説明します。

ヒント: ほとんどのユーザはこれらのプロプライエタリドライバは必要ありません。

Purpose of proprietary components

AMD releases their open source drivers via standard distribution channels. And they also periodically do releases of their Radeon Software for Linux suite, which includes both open and proprietary components. Open source components are not needed from there, and proprietary components are repacked from the latest ubuntu lts version. They are published in AUR in the amdgpu-pro-installer package base.

Comment by the AMD explaining why they still package close source drivers:

These days our packaged drivers are mostly intended for:
* customers using slower moving enterprise/LTS distros which do not automatically pick up the latest graphics drivers - we offer them both open source and proprietary/workstation options
* customers using workstation apps who need the extra performance/certification from a workstation-oriented driver (although Marek has done a lot of great work over the last year to improve Mesa performance on workstation apps)
* The third target audience is customers looking for ready-to-go OpenCL, either for use with the packaged open/closed drivers or with the upstream-based stack in a recent distro.

There are several proprietary components: OpenGL, OpenCL, Vulkan and AMF. Sometimes you may want to use these components due to specific features that open source components may lack.

AMDGPU PRO OpenGL is a proprietary, binary userland driver, which works on top of the open-source amdgpu kernel driver. From Radeon Software 18.50 vs Mesa 19 benchmarks article: When it comes to OpenGL games, the RadeonSI Gallium3D driver simply dominates the proprietary AMD OpenGL driver. Users of graphic cards other than Radeon Pro are advised to use the amdgpu graphics stack. Mostly used because of lacking compatibility layers that some software relies on. See gentoo wiki linked below.

AMDGPU PRO Vulkan - currently the only implementation that has ray tracing (however, reported by users as glitchy). Also it is required dependency for AMF.

AMDGPU PRO OpenCL - used because Mesa OpenCL is not fully complete. Proprietary component only for Polaris GPUs. The onward GPUs use the open ROCm OpenCL.

AMDGPU AMF - used for gpu encoding/decoding.

インストール

プロプライエタリな OpenGL 実装は amdgpu-pro-libgl^AUR をインストールしてください。オプションで 32 ビットアプリケーションのサポート用の lib32-amdgpu-pro-libgl^AUR もインストールしてください。

利用可能な OpenCL の実装については GPGPU#AMD/ATI を見てください。

プロプライエタリな Vulkan 実装は vulkan-amdgpu-pro^AUR をインストールしてください。オプションで 32 ビットアプリケーションのサポート用の lib32-vulkan-amdgpu-pro^AUR もインストールしてください。

Advanced Media Framework の実装は amf-amdgpu-pro^AUR をインストールしてください。

Usage

Using proprietary OpenGL

Launch your application with progl prefix, for example:

$ progl glmark2

How to ensure you are using AMDGPU-PRO driver

Run the following command:

$ glxinfo | grep "OpenGL vendor string" | cut -f2 -d":" | xargs

If it returns AMD, then you are running open source driver. If it returns Advanced Micro Devices, Inc., then you are running proprietary driver.

Alternatively, run glmark2. When using open driver, in OpenGL Information you will see:

   GL_VENDOR:     AMD
   GL_RENDERER:   Radeon RX 580 Series (POLARIS10, DRM 3.40.0, 5.10.7-arch1-1, LLVM 11.0.1)
   GL_VERSION:    4.6 (Compatibility Profile) Mesa 20.3.3

But when using closed driver, you will see:

   GL_VENDOR:     ATI Technologies Inc.
   GL_RENDERER:   Radeon RX 580 Series
   GL_VERSION:    4.6.14756 Compatibility Profile Context

Using proprietary Vulkan

Launch your application with vk_pro prefix, for example:

$ vk_pro vkmark

See Vulkan#Selecting via AMD Vulkan Prefixes for more information.

Using Advanced Multimedia Framework

See FFmpeg#AMD AMF

Troubleshooting

Intel + AMD hybrid graphics

For Users of a hybrid setup with both an Intel GPU and an AMD GPU, usage of the proprietary AMDGPU Pro Workstation Driver might not work as expected due to different MESA implementations. The symptom is the following: when you boot your machine, you get a black screen, but with your mouse cursor is moving normally. Unfortunately, Reverse PRIME is not a solution. See this developer response.

Uninstalling packages

If you are in trouble, for example, you cannot login to your system due to black screen, you can revert all back by uninstalling all packages related to amdgpu pro. Switch to the tty2 (ctrl+alt+f2), login to the system and run pacman -R $(pacman -Qg Radeon_Software_for_Linux | cut -f2 -d" ") and reboot.

Southern Islands (SI) or Sea Islands (CIK) GPUs

If using Southern Islands (SI) or Sea Islands (CIK) GPU, when running clinfo, you get:

amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x.

then ensure you are using amdgpu driver, but not radeon. Check which driver is currently in use with lspci -k:

03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Opal XT [Radeon R7 M265/M365X/M465]
        Subsystem: Acer Incorporated [ALI] Aspire V5 Radeon R7 M265
        Kernel driver in use: radeon
        Kernel modules: radeon, amdgpu

See AMDGPU#Enable Southern Islands (SI) and Sea Islands (CIK) support for more information.
