Add inter-process communcation to shader cache This change allows running several instances of CTS which share a single shader cache. std::map which was used to hold the cache index was replaced by a simple binary search tree implementation in order to play nice in a pre-allocated buffer. Benchmarking gives approximately same performance or better in random cases. Worst case behavior is terrible, but did not occur while testing after integrating with CTS. By default the size of the index is 1M entries, taking 16M of memory. This memory pool is not resized dynamically, and will assert if over 1M unique shaders are inserted to the cache. Additional small improvement to the shader cache behavior avoids re-hashing the cache key at cache miss. For platforms that do not support IPC, the IPC code can be compiled out using a predefined macro DISABLE_SHADERCACHE_IPC. The IPC behavior is disabled by default, leading to old behavior, except for the std::map to bst change and no re-hashing.

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 dEQP 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.
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/
