Restore the legacy PowerVR SDK 'BasicTnL' OpenGL ES 1.1 sample OpenGL ES 1.1 will be removed from the main branch, but this sample can remain available as basic test of a legacy OpenGL ES 1.1 build. This partially reverts https://swiftshader-review.googlesource.com/c/SwiftShader/+/43190 Bug: b/147516027 Change-Id: I344b5c591e6560317c53cfa2da9f092e948e3cfa Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/45709 Reviewed-by: Nicolas Capens <firstname.lastname@example.org> Tested-by: Nicolas Capens <email@example.com>
SwiftShader is a high-performance CPU-based implementation of the Vulkan and OpenGL ES graphics APIs12. Its goal is to provide hardware independence for advanced 3D graphics.
SwiftShader libraries can be built for Windows, Linux, and Mac OS X.
Android and Chrome (OS) build environments are also supported.
For building the Vulkan ICD library, use Visual Studio 2019 to open the project folder and wait for it to run CMake. Open the CMake Targets View in the Solution Explorer and select the vk_swiftshader project to build it.
cd build cmake .. make --jobs=8 ./vk-unittests
The SwiftShader libraries act as drop-in replacements for graphics drivers.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. 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.

All changes require a Change-ID tag in the commit message. A commit hook may be used to add this tag automatically, and can be found at: https://gerrit-review.googlesource.com/tools/hooks/commit-msg. To clone the repository and install the commit hook in one go:
git clone https://swiftshader.googlesource.com/SwiftShader && (cd SwiftShader && curl -Lo `git rev-parse --git-dir`/hooks/commit-msg https://gerrit-review.googlesource.com/tools/hooks/commit-msg ; chmod +x `git rev-parse --git-dir`/hooks/commit-msg)
Changes are uploaded to Gerrit by executing:
git push origin HEAD:refs/for/master
SwiftShader's OpenGL ES implementation can be tested using the dEQP test suite.
See docs/dEQP.md for details.
The third_party directory contains projects which originated outside of SwiftShader:
subzero contains a fork of the Subzero project. It is part of Google Chrome‘s (Portable) Native Client project. Its authoritative source is at https://chromium.googlesource.com/native_client/pnacl-subzero/. The fork was made using git-subtree to include all of Subzero’s history, and until further notice it should not diverge from the upstream project. Contributions must be tested using the README instructions, reviewed at https://chromium-review.googlesource.com, and then pulled into the SwiftShader repository.
llvm-subzero contains a minimized set of LLVM dependencies of the Subzero project.
googletest contains the Google Test project, as a Git submodule. It is used for running unit tests for Chromium, and Reactor unit tests. Run
git submodule update --init to obtain/update the code. Any contributions should be made upstream.
