Fix shader operator tests' precision expectation es3fShaderOperatorTests.cpp takes the reported precision for lowp and mediump (through glGetShaderPrecisionFormat) and tests that that many bits are actually supported by the type. glGetShaderPrecisionFormat is a legacy function that's not very meaningful on modern hardware (see Vulkan issue #2931), and there is no equivalent for its functionality in Vulkan. This relevant tests are changed such that the test now verifies that _at least_ that many bits are used in lowp and mediump operations, rather than _exactly_. This aligns with the semantics of RelaxedPrecision in SPIR-V. Affected tests: dEQP-GLES3.functional.shaders.operator.* Components: OpenGL ES VK-GL-CTS issue: 3344 Change-Id: I88a38d6ee067de8313f25327578c6666c257dc8b
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 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/
