Added initial set of tests for the cl_khr_semaphore extension (#1428) * Added initial set of tests for the cl_khr_semaphore extension * Fixes to address first round of reviews for cl_khr_semaphore tests
This it the OpenCL CTS for all versions of the Khronos OpenCL standard.
The CTS supports Linux, Windows, macOS, and Android platforms. In particular, GitHub Actions CI builds against Ubuntu 20.04, Windows-latest, and macos-latest.
Compiling the CTS requires the following CMake configuration options to be set:
CL_INCLUDE_DIRPoints to the unified OpenCL-Headers.
CL_LIB_DIRDirectory containing the OpenCL library to build against.
OPENCL_LIBRARIESName of the OpenCL library to link.
It is advised that the OpenCL ICD-Loader is used as the OpenCL library to build against. Where
CL_LIB_DIR points to a build of the ICD loader and
OPENCL_LIBRARIES is “OpenCL”.
Steps on a Linux platform to clone dependencies from GitHub sources, configure a build, and compile.
git clone https://github.com/KhronosGroup/OpenCL-CTS.git git clone https://github.com/KhronosGroup/OpenCL-Headers.git git clone https://github.com/KhronosGroup/OpenCL-ICD-Loader.git mkdir OpenCL-ICD-Loader/build cmake -S OpenCL-ICD-Loader -B OpenCL-ICD-Loader/build \ -DOPENCL_ICD_LOADER_HEADERS_DIR=$PWD/OpenCL-Headers cmake --build ./OpenCL-ICD-Loader/build --config Release mkdir OpenCL-CTS/build cmake -S OpenCL-CTS -B OpenCL-CTS/build \ -DCL_INCLUDE_DIR=$PWD/OpenCL-Headers \ -DCL_LIB_DIR=$PWD/OpenCL-ICD-Loader/build \ -DOPENCL_LIBRARIES=OpenCL cmake --build OpenCL-CTS/build --config Release
A build of the CTS contains multiple executables representing the directories in the
test_conformance folder. Each of these executables contains sub-tests, and possibly smaller granularities of testing within the sub-tests.
--help output on each executable for the list of sub-tests available, as well as other options for configuring execution.
If the OpenCL library built against is the ICD Loader, and the vendor library to be tested is not registered in the default ICD Loader location then the OCL_ICD_FILENAMES environment variable will need to be set for the ICD Loader to detect the OpenCL library to use at runtime. For example, to run the basic tests on a Linux platform:
Testing OpenCL drivers which do not have a runtime compiler can be done by using additional command line arguments provided by the test harness for tests which require compilation, these are:
--compilation-mode Selects if OpenCL-C source code should be compiled using an external tool before being passed on to the OpenCL driver in that form for testing. Online is the default mode, but also accepts the values
--compilation-cache-mode Controls how the compiled OpenCL-C source code should be cached on disk.
--compilation-cache-path Accepts a path to a directory where the compiled binary cache should be stored on disk.
--compilation-program Accepts a path to an executable (default: cl_offline_compiler) invoked by the test harness to perform offline compilation of OpenCL-C source code. This executable must match the interface description.
The Khronos Conformance Process Document details the steps required for a conformance submissions. In this repository opencl_conformance_tests_full.csv defines the full list of tests which must be run for conformance. The output log of which must be included alongside a filled in submission details template.
Utility script run_conformance.py can be used to help generating the submission log, although it is not required.
Git tags are used to define the version of the repository conformance submissions are made against.
Contributions are welcome to the project from Khronos members and non-members alike via GitHub Pull Requests (PR). Alternatively, if you've found a bug or have a questions please file an issue in the GitHub project. First time contributors will be required to sign the Khronos Contributor License Agreement (CLA) before their PR can be merged.
PRs to the repository are required to be
clang-format clean to pass CI. Developers can either use the
git-clang-format tool locally to verify this before contributing, or update their PR based on the diff provided by a failing CI job.
