Properly enable Sample Shading in Fragment Shading Rate tests Vulkan spec states: > Sample shading is enabled for a graphics pipeline: > > * If the interface of the fragment shader entry point of the graphics > pipeline includes an input variable decorated with SampleId or > SamplePosition. In this case minSampleShadingFactor takes the value > 1.0. > * Else if the sampleShadingEnable member of the > VkPipelineMultisampleStateCreateInfo structure specified when > creating the graphics pipeline is set to VK_TRUE. In this case > minSampleShadingFactor takes the value of > VkPipelineMultisampleStateCreateInfo::minSampleShading. > > Otherwise, sample shading is considered disabled. This change ensures that sample shading is properly enabled in the Fragment Shading Rate tests relying on it by using gl_SampleId. Components: Vulkan Affects: dEQP-VK.fragment_shading_rate.sampleshadinginput.* VK-GL-CTS Issue: 2966 Change-Id: I7fad0ed7694a2d26ef7db9ea268fa5d6f93264a6
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 *.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-v8a cp ../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/
