This page describes close source drivers for AMD GPUs.
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.
For proprietary OpenGL implementation, installAUR and optionally AUR for 32 bit applications support.
For available OpenCL implementations see GPGPU#AMD/ATI.
For proprietary Vulkan implementation, installAUR and optionally AUR for 32 bit applications support.
For Advanced Media Framework implementation, installAUR
For OBS to work with it useAUR
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, for example:
$ vk_pro vkmark
See Vulkan#Selecting via AMD Vulkan Prefixes for more information.
Using Advanced Multimedia Framework
See FFmpeg#AMD AMF
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.
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 a virtual console (with e.g.
Ctrl+Alt+F2), login and run:
# pacman -R $(pacman -Qg Radeon_Software_for_Linux | cut -f2 -d" "
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:
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.
