Amd open source driver linux và nvidia
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 Product SupportThe AMD Open Source Driver for Vulkan is designed to support the following AMD GPUs:
Operating System SupportThe AMD Open Source Driver for Vulkan is designed to support following distros and versions on both the AMDGPU upstream driver stack and the AMDGPU Pro driver stack:
The driver has not been well tested on other distros and versions. You may try it out on other distros and versions of your choice.
Feature Support and PerformanceThe AMD Open Source Driver for Vulkan is designed to support the following features:
The following features and improvements are planned in future releases (Please refer to Release Notes for update of each release):
Known Issues
How to ContributeYou are welcome to submit contributions of code to the AMD Open Source Driver for Vulkan. The driver is built from source code in five repositories: LLVM, XGL, LLPC, GPURT and PAL. For changes to LLVM, you should submit contribution to the LLVM trunk. Commits there will be evaluated to merge into the amd-gfx-gpuopen-master branch periodically. For changes to XGL, LLPC, GPURT and PAL, please create a pull request against the dev branch. After your change is reviewed and if it is accepted, it will be evaluated to merge into the master branch in a subsequent regular promotion. IMPORTANT: By creating a pull request, you agree to allow your contribution to be licensed by the project owners under the terms of the MIT License. When contributing to XGL, LLPC, GPURT and PAL, your code should:
Please make each contribution reasonably small. If you would like to make a big contribution, like a new feature or extension, please raise an issue first to allow planning to evaluate and review your work.

Turn on DRI3 and disable modesetting X driverAdd following lines in /usr/share/X11/xorg.conf.d/10-amdgpu.conf:
And make sure following line is NOT included in the section: Required SettingsOn the AMDGPU upstream driver stack with libdrm version lower than 2.4.92, the max number of IB per submission MUST be limited to 4 (the default setting in AMD Open Source driver for Vulkan is 16). This can be accomplished via the Runtime Settings mechanism by adding the following line to amdPalSettings.cfg:
Install with pre-built driverYou could generate the installation package with below command while building driver: Ubuntu
RedHat
You could also download pre-built package from https://github.com/GPUOpen-Drivers/AMDVLK/releases for each code promotion in master branch. Below is the installation instruction: Ubuntu 20.04, 22.04
RedHat 8.6, 9.0
For Ubuntu, you could also install the latest driver build from https://repo.radeon.com:
Runtime SettingsThe driver exposes many settings that can customize the driver's behavior and facilitate debugging. You can add/edit settings in amdVulkanSettings.cfg or amdPalSettings.cfg file under one of below paths, formatted with one
Some example settings are listed below:
All available settings can be determined by examining below source files that define them.
Runtime settings are
only read at device initialization, and cannot be changed without restarting the application. If running on a system with multiple GPUs, the same settings will apply to all of them. Lines in the settings file that start with Enable extensions under developmentThe extensions under development are not enabled by default in driver. You can enable them through environment variable:
or
The extension name is case-insensitive. PAL GpuProfiler LayerThe GpuProfiler is an optional layer that is designed to intercept the PAL interface to provide basic GPU profiling support. Currently, this layer is controlled exclusively through runtime settings and outputs its results to file. You can use the following Runtime Settings to generate .csv files with GPU timings of work performed during the designated frames of an application (one file for each frame):
You can use the script timingReport.py to analyze the profiling log:
Dump Pipelines and ShadersThe output of timeReport.py includes the information of top pipelines like below:
You can add the following settings to amdPalSettings.cfg to dump the information of each pipeline:
PipelineDumpDir is a sub-path relative to $AMD_DEBUG_DIR or $TMPDIR or /var/tmp/, default value is "spvPipeline/". The pipeline dump file is named in the format like Pipeline PAL Debug OverlayPAL's debug overlay can be enabled to display real time statistics and information on top of a running application. This includes a rolling FPS average, CPU and GPU frame times, and a ledger tracking how much video memory has been allocated from each available heap. Benchmarking (i.e., "Benchmark (F11)") is currently unsupported.
