Open Source Driver Updater software free downloads. Open Source Driver Updater shareware, freeware, demos: Actual ODBC Driver for Open Source Databases by Actual Technologies LLC, Universal Driver Updater by Universal Driver Updater, Driver-Updater by DRIVER DETAILS etc. Nouveau: Accelerated Open Source driver for nVidia cards. The nouveau project aims to build high-quality, free/libre software drivers for nVidia cards. “Nouveau” nuvo is the French word for “new”.Nouveau is composed of a Linux kernel KMS driver (nouveau), Gallium3D drivers in Mesa, and the Xorg DDX (xf86-video-nouveau). A free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. 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.

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 VkPipeline object are compiled as a single entity using the LLVM-Based Pipeline Compiler (LLPC) library. LLPC builds on LLVM's existing shader compilation infrastructure for AMD GPUs to generate code objects compatible with PAL's pipeline ABI. Notably, AMD's closed-source Vulkan driver currently uses a different pipeline compiler, which is the major difference between AMD's open-source and closed-source Vulkan drivers.

Operating System Support

The AMD Open Source Driver for Vulkan is designed to support following distros on both the AMDGPU upstream driver stack and the AMDGPU Pro driver stack:

  • Ubuntu 18.04 (64-bit version)
  • Ubuntu 16.04.4 (64-bit version)
  • RedHat 7.5 (64-bit version)

The driver has not been tested on other distros. You may try it out on other distros of your choice.

Note: To run the Vulkan driver with AMDGPU upstream driver stack on SI and CI generation GPUs, amdgpu.si_support and amdgpu.cik_support need to be enabled in kernel

Feature Support and Performance

The AMD Open Source Driver for Vulkan is designed to support the following features:

  • Vulkan 1.1
  • More than 30 extensions
  • Radeon™ GPUProfiler tracing
  • Built-in debug and profiling tools
  • Mid-command buffer preemption and SR-IOV virtualization

The following features and improvements are planned in future releases (Please refer to Release Notes for update of each release):

  • Upcoming versions of the Vulkan API
  • Hardware performance counter collection through RenderDoc
  • LLPC optimizations to improve GPU-limited performance and compile time
  • Optimizations to improve CPU-limited performance

Known Issues

  • CTS may hang in VK.synchronization.internally_synchronized_objects.pipeline_cache_compute with Linux kernel versions lower than 4.13
  • The driver can only work with firmware of ME feature version >= 25 (you can check the version with command 'sudo cat /sys/kernel/debug/dri/0/amdgpu_firmware_info'). If you are using upstream stack with GPUs of SI or CI family, you may need to upgrade the kernel to 4.19 or later version and firmware (under /lib/firmware/amdgpu/) to the right version from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu, and then update ramfs (sudo mkinitramfs -o /boot/initrd.img-`uname -r` `uname -r`)

How to Contribute

You are welcome to submit contributions of code to the AMD Open Source Driver for Vulkan.

The driver is built from source code in four repositories: LLVM, XGL, LLPC and PAL.

For changes to LLVM, you should submit contribution to the LLVM trunk. Commits there will be evaluated to merge into the amd-vulkan-master branch periodically.

For changes to XGL, LLPC 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 and PAL, your code should:

  • Match the style of nearby existing code. Your code may be edited to comply with our coding standards when it is merged into the master branch.
  • Avoid adding new dependencies, including dependencies on STL.

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.

Note: Since PAL is a shared component that must support other APIs, other operating systems, and pre-production hardware, you might be asked to revise your PAL change for reasons that may not be obvious from a pure Linux Vulkan driver perspective.

And make sure following line is NOT included in the section:

Required Settings

On 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 driver

You could download and install pre-built deb package (compatible with Ubuntu 16.04 and 18.04) from https://github.com/GPUOpen-Drivers/AMDVLK/releases for each stable code promotion in master branch:

You could also install the latest driver build from http://repo.radeon.com:

Runtime Settings

The driver exposes many settings that can customize the driver's behavior and facilitate debugging. You can add/edit settings in amdPalSettings.cfg file under one of below paths, formatted with one name,value pair per line:

  • /etc/amd
  • $XDG_CONFIG_HOME
  • $HOME/.config

Some example settings are listed below:

Setting NameValid ValuesComment
ShaderCacheMode0: disable cache
1: runtime cache
2: cache to disk		Runtime cache is the default mode. For 'cache to disk', the cache file is generated under $AMD_SHADER_DISK_CACHE_PATH/AMD/LlpcCache or $XDG_CACHE_HOME/AMD/LlpcCache or $HOME/.cache/AMD/LlpcCache
IFH0: default
1: drop all submits
Infinitely Fast Hardware. Submit calls are dropped before being sent to hardware. Useful for measuring CPU-limited performance.
EnableVmAlwaysValid0: disable
1: default
2: force enable
1 is the default setting which enables the VM-always-valid feature for kernel 4.16 and above. The feature can reduce command buffer submission overhead related to virtual memory management.
IdleAfterSubmitGpuMaskBitmask of GPUs (i.e., bit 0 is GPU0, etc.)Forces the CPU to immediately wait for each GPU submission to complete on the specified set of GPUs.

All available settings can be determined by examining below source files that define them.

  • ../xgl/icd/settings/settings.cfg (API layer settings)
  • ../pal/src/core/settings_core.json (PAL hardware-independent settings)
  • ../pal/src/core/hw/gfxip/gfx6/settings_gfx6.json (PAL GFX6-8 settings)
  • ../pal/src/core/hw/gfxip/gfx9/settings_gfx9.json (PAL GFX9+ settings)

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 ; will be treated as comments.

Enable extensions under development

The 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 Layer

The 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):

Setting NameValueComment
GpuProfilerMode0: disable
1: enable with sqtt off
2: enable with sqtt for thread trace
3: enable with sqtt for RGP		Enables and sets the SQTT mode for the GPU performance profiler layer. Actual capture of performance data must be specified via frame number with GpuProfilerConfig_StartFrame or by pressing shift-F11.
GpuProfilerConfig.LogDirectory<directory-path>The directory path is relative to $AMD_DEBUG_DIR or $TMPDIR or /var/tmp/, default value is 'amdpal/'. Your application must have write permissions to the directory. The profiling logs are output to a subdirectory that is named in the format like <AppName><yyyy-MM-dd><HH:mm:ss>.
GpuProfilerConfig.Granularity0: per-draw
1: per-cmdbuf		Defines what is measured/profiled. Per-draw times individual commands (such as draw, dispatch, etc.) inside command buffers, while per-cmdbuf only profiles entire command buffers in aggregate.
GpuProfilerConfig.StartFramePositive integerFirst frame to capture data for. If StartFrame and FrameCount are not set, all frames will be profiled.
GpuProfilerConfig.FrameCountPositive integerNumber of frames to capture data for.
GpuProfilerConfig.RecordPipelineStats0, 1Gathers pipeline statistic query data per entry if enabled.

You can use the script timingReport.py to analyze the profiling log:

Dump Pipelines and Shaders

The 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<Type>_<Compiler_Hash>.pipe. For example, the above top 1 pipeline is dumped to PipelineVsFs_0xD91D15E42D62DCBB.pipe. The shaders referenced by each pipeline are also dumped to .spv files.

PAL Debug Overlay

PAL'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.

Setting NameValueComment
DebugOverlayEnabled0, 1Enables the debug overlay.
DebugOverlayConfig.DebugOverlayLocation0: top-left
1: top-right
2: bottom-left
3: bottom-right		Determines where the overlay text should be displayed. Can be used to avoid collision with important rendering by the application.
DebugOverlayConfig.PrintFrameNumber0, 1Reports the current frame number. Useful when determining a good frame range for profiling with the GpuProfiler layer.
DebugOverlayConfig.TimeGraphEnable0, 1Enables rendering of a graph of recent CPU and GPU frame times.
