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。
{{Tip|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 [https://aur.archlinux.org/pkgbase/amdgpu-pro-installer amdgpu-pro-installer] package base.

[https://www.phoronix.com/forums/forum/phoronix/latest-phoronix-articles/1316628-radeon-software-for-linux-22-10-driver-being-prepared-for-release?p=1316713#post1316713 Comment] by the AMD explaining why they still package close source drivers:
{{Text art|<nowiki>
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 [https://www.phoronix.com/vr.php?view=27266 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 [https://www.amd.com/en/support/kb/release-notes/amdgpu-installation 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 {{AUR|amdgpu-pro-libgl}} 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 {{AUR|lib32-amdgpu-pro-libgl}} 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 {{AUR|vulkan-amdgpu-pro}} 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 {{AUR|lib32-vulkan-amdgpu-pro}} もインストールしてください。

Advanced Media Framework の実装は {{AUR|amf-amdgpu-pro}} 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 {{ic|AMD}}, then you are running open source driver. If it returns {{ic|Advanced Micro Devices, Inc.}}, then you are running proprietary driver.

Alternatively, run [[Benchmarking#glmark2|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, [[PRIME#Reverse PRIME|Reverse PRIME]] is not a solution. See [https://gitlab.freedesktop.org/drm/amd/-/issues/985#note_359417 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 {{ic|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 {{ic|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 {{ic|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.
