![]() The SwiftShader project is licensed under the Apache License Version 2.0. Any contributions should be made upstream. Run git submodule update -init to obtain/update the code. It is used for running unit tests for Chromium, and Reactor unit tests. Googletest contains the Google Test project, as a Git submodule. PowerVR_SDK contains a subset of the PowerVR Graphics Native SDK for running several sample applications. Llvm-subzero contains a minimized set of LLVM dependencies of the Subzero project. The fork was made using git-subtree to include all of Subzero’s history. It originates from Google Chrome‘s (Portable) Native Client project. Subzero contains a fork of the Subzero project. The third_party directory contains projects which originated outside of SwiftShader: SwiftShader's Vulkan implementation can be tested using the dEQP test suite. Most IDEs come with clang-format support, but may require upgrading/downgrading to the clang-format version 11.0.0 release version (notably Chromium's buildtools has a clang-format binary which can be an in-between revision which produces different formatting results). ![]() Notably, presubmit.sh verifies the change has been formatted using clang-format 11.0.1. Some tests will automatically be run against the change. When ready, add a project owner as a reviewer on your change. On Windows, this command line requires using the Git Bash Shell.Ĭhanges are uploaded to Gerrit by executing: git push origin HEAD:refs/for/master You can execute git clone and manually place the commit hook in SwiftShader/.git/hooks/, or to clone the repository and install the commit hook in one go: git clone & (cd SwiftShader & git submodule update -init -recursive third_party/git-hooks &. A commit hook may be used to add this tag automatically, and can be found at. Next, authenticate your account here: (use the same e-mail address as the one configured as the Git commit author).Īll changes require a Change-ID tag in the commit message. You must sign in to this site with a Google Account before changes can be uploaded. Īll changes must be reviewed and approved in the Gerrit review tool at. The canonical repository for SwiftShader is hosted at. See CONTRIBUTING.txt for important contributing requirements. To learn more about how Vulkan loading works, read the official documentation here. Alternatively, you can set the VK_ICD_FILENAMES environment variable to the path to vk_swiftshader_icd.json file that is generated under the build directory (e.g.\SwiftShader\build\Windows\vk_swiftshader_icd.json). SwiftShader's ICD is named libvk_swiftshader.dll, but it can be renamed to vulkan-1.dll to be loaded directly by the application. This ‘loader’ library then redirects API calls to the actual Installable Client Driver (ICD). In general, Vulkan applications look for a shared library named vulkan-1.dll on Windows ( vulkan-1.so on Linux). On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first. On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. The SwiftShader libraries act as drop-in replacements for graphics drivers. Open the CMake Targets View in the Solution Explorer and select the vk_swiftshader project to build it. To build the Vulkan ICD library, use Visual Studio 2019 to open the project folder and wait for it to run CMake. Tip: Set the CMAKE_BUILD_PARALLEL_LEVEL environment variable to control the level of parallelism. Install CMake for Linux, macOS, or Windows and use either the GUI or run the following terminal commands: cd build SwiftShader libraries can be built for Windows, Linux, and macOS.Īndroid and Chrome (OS) build environments are also supported. NOTE: The ANGLE project can be used to achieve a layered implementation of OpenGL ES 3.1 (aka. Its goal is to provide hardware independence for advanced 3D graphics. SwiftShader is a high-performance CPU-based implementation of the Vulkan 1.3 graphics API.
