Reland: Support host decoding with update_color_buffer on minigbm minigbm creates an NV12 image when the guest wanted yuv_420_888. our host decoder outputs yuv_420_888, but this isn't compatible with nv21, and resulted in garbled images when fed to YUVConverter. but gfxstream never created a yuv_420_888 gpu image on the host anyway. All we need to do is explicitly tell YUVConverter to convert from yuv_420_888. Bug: 162770284 Change-Id: I3788183e7c94adfd0d52caafbbe67a1ed0d23c77
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.
CMakeLists.txt: specifies all host-side build targets. This includes all backends along with client/server setups that live only on the host. SomeAndroid.bp: specifies all guest-side build targets for Android:BUILD.gn: specifies all guest-side build targets for Fuchsiabase/: common libraries that are built for both the guest and host. Contains utility code related to synchronization, threading, and suballocation.protocols/: implementations of protocols for various graphics APIs. May contain code generators to make it easy to regen the protocol based on certain things.host-common/: implementations of host-side support code that makes it easier to run the server in a variety of virtual device environments. Contains concrete implementations of auxiliary virtual devices such as Address Space Device and Goldfish Pipe.stream-servers/: implementations of various backends for various graphics APIs that consume protocol. gfxstream-virtio-gpu-renderer.cpp contains a virtio-gpu backend implementation.
