Reduce FBO rebinding on make current This CL checks if it actually needs to rebind FBO and set up framebuffer attachments when calling initDefaultFBO. glBindFramebuffer seems to crash frequenly on some drivers. Hopefully we could reduce crash rate by reducing the amount of bind framebuffer calls. Bug: 281872037 Change-Id: I622b19be25955a2909c30643a8de0baa872b420c GitOrigin-RevId: 2367fff5432290d6b610552f3ade6aa0f45b36d9
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 the opengl lib is installed. Otherwise, sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev Make sure you are using Clang as your CC
and clang++ as yourCXX
. 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)
Check out the gfxstream-protocols repo at ../../../external/gfxstream-protocols
relative to the root directory of this repo, and run the scripts/generate-vulkan-sources.sh
script in the gfxstream-protocols
root folder.
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.
