Fix invocation count verification The shaders in these tests track the number of invocations executed and verify that against the expected number of invocations for the test. The spec only guarentees that each fragment is executed at least once. So an implementation is free to execute each fragment multiple times if required (for example, an implementation might required a shader to be run at sample rate). Change this verification to only check against the minmum number of invocations. Affects: dEQP-VK.fragment_operations.early_fragment.samplemask_* Components: Vulkan VK-GL-CTS issue: 3278 Change-Id: I93f1aa42dd6a13486bed044e361671e5a2f2cb07 (cherry picked from commit 72cf9dc888972c4dc8ed95358f0f56c6a40e072e)
This repository contains a GPU testing suite called dEQP (drawElements Quality Program). dEQP contains tests for several graphics APIs, including OpenGL ES, EGL, and Vulkan.
Up-to-date documentation for the dEQP is available at Android Open Source Project site.
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.
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
Assuming ANGLE shared objects are generated into
dEQP.apk will be generated with
--abis arm64-v8a, issue the following commands:
cd ~/chromium/src/out/Release/ mkdir arm64-v8a && cd arm64-v8a cp ../lib*_angle.so .
--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/
