Khronos Vulkan, OpenGL, and OpenGL ES Conformance Tests
This repository contains Khronos Conformance Testing Suite called VK-GL-CTS
which originated from dEQP (drawElements Quality Program).
VK-GL-CTS contains tests for several graphics APIs, including
OpenGL, OpenGL ES, EGL, Vulkan, and Vulkan SC.
Up-to-date documentation for VK-GL-CTS is available at:
The .qpa logs generated by the conformance tests may contain embedded PNG images of the results.
These can be viewed with scripts/qpa_image_viewer.html, by opening the file
with a web browser and following its instructions, or using the
Cherry
tool.
This repository includes Khronos Vulkan CTS under external/vulkancts directory.
For more information see Vulkan CTS README.
This repository includes Khronos OpenGL / OpenGL ES CTS under external/openglcts directory.
For more information see OpenGL / OpenGL ES CTS README.
When configuring the source code of VK-GL-CTS for running either Vulkan
Conformance Tests or OpenGL(ES) Conformance Tests as described above, CMake will
generate build files that, by default on desktop platforms, will build every
possible project binary. This may be undesirable due the amount of time and disk
space needed to perform the build.
One way of selecting only a subset of the targets to be built is using CMake’s
target selection mechanism. For example, the following command will only builddeqp-vk, the main Vulkan Conformance Tests binary:
cmake --build BUILD_DIRECTORY --target deqp-vk
When building only a subset of targets is the preferred default behavior for a
given working copy or build directory, there’s a second target selection
mechanism that can be used to avoid passing the --target option every time:
the SELECTED_BUILD_TARGETS CMake option. If set to a non-empty value, only the
targets listed in that configuration option, separated by spaces, will be built.
For example, passing -DSELECTED_BUILD_TARGETS="deqp-vk deqp-vksc" when
configuring the project will make cmake --build BUILD_DIRECTORY act as if it
had been passed --target deqp-vk --target deqp-vksc as additional arguments.
IMPORTANT: Target subset selection may not have been thoroughly tested in
all enviroments and situations, and it does not replace the instructions given
for the purposes of creating a conformance submission.
ANGLE can be built for Android by following the instructions
here.
The resulting ANGLE shared object libraries can be linked against and embedded into dEQP.apk with
the --angle-path option. This will cause dEQP.apk to use the ANGLE libraries for OpenGL ES
calls, rather than the native drivers.
An ABI must be specified and the directory structure containing the ANGLE shared objects must match
it so the build system can find the correct *.so files.
Assuming ANGLE shared objects are generated into ~/chromium/src/out/Release/ and dEQP.apk will
be generated with --abis arm64-v8a, issue the following commands:
cd ~/chromium/src/out/Release/mkdir arm64-v8a && cd arm64-v8acp ../lib*_angle.so .
The --angle-path ~/chromium/src/out/Release/ option can then be used to link against and embed the
ANGLE shared object files. The full command would be:
python scripts/android/build_apk.py --sdk <path to Android SDK> --ndk <path to Android NDK> --abis arm64-v8a --angle-path ~/chromium/src/out/Release/
In order to run the vulkan video decode test suite, you’ll need to run the script external/fetch_video_decode_samples.py
prior building and running any test suite such as dEQP-VK.video.decode.*. It will download the video clips in external/vulkancts/data/vulkan/video.
To run the vulkan video encode test suite, you’ll need to run the script external/fetch_video_encode_samples.py
prior building and running any test suite such as dEQP-VK.video.encode.*. It will download the video clips in external/vulkancts/data/vulkan/video.
