gl: Support ColorBuffers of A2B10G10R10 format. There's no equivalent internal formats to Vulkan A2B10G10R10 format in GL, which makes it hard to create a color buffer with such format. In this change, we introduce an enum GL_BGR10_A2_ANGLEX to represent A2B10G10R10 formats and translate the format to corresponding format/type when calling glTexImage2D to create textures.

Graphics Streaming Kit is a code generator that makes it easier to serialize and forward graphics API calls from one place to another:
Make sure the latest CMake is installed. Make sure you are using Clang as your CC
and CXX
. Then
mkdir build cd build cmake . ../ make -j24
Unit tests:
make test
Make sure the latest CMake is installed. Make sure Visual Studio 2019 is installed on your system along with all the Clang C++ toolchain components. Then
mkdir build cd build cmake . ../ -A x64 -T ClangCL
A solution file should be generated. Then open the solution file in Visual studio and build the gfxstream_backend
target.
Be in the Android build system. Then
m libgfxstream_backend
It then ends up in out/host
This also builds for Android on-device.
libgfxstream_backend.(dll|so|dylib)
scripts/generate-vulkan-sources.sh
If you're in an AOSP checkout, this will also modify contents of the guest Vulkan encoder in ../goldfish-opengl
.
First, build build/gfxstream-generic-apigen
. Then run
scripts/generate-apigen-source.sh
There are a bunch of test executables generated. They require libEGL.so
and libGLESv2.so
and libvulkan.so
to be available, possibly from your GPU vendor or ANGLE, in the $LD_LIBRARY_PATH
.
There are a bunch of test executables generated. They require libEGL.dll
and libGLESv2.dll
and vulkan-1.dll
to be available, possibly from your GPU vendor or ANGLE, in the %PATH%
.
These are currently not built due to the dependency on system libEGL/libvulkan to run correctly.
