Graphics Streaming Kit (formerly: Vulkan Cereal)

Graphics Streaming Kit is a code generator that makes it easier to serialize and forward graphics API calls from one place to another:

From a virtual machine guest to host for virtualized graphics
From one process to another for IPC graphics
From one computer to another via network sockets

Build

Run ./build-host.sh, or:

mkdir build
cd build
cmake . ../ -DCMAKE_TOOLCHAIN_FILE=../toolchain/toolchain-linux-x86_64.cmake
# Or toolchain-darwin, or toolchain-windows_msvc depending on host platform
make -j24

Project layout and overall evolution plan

For fast iteration, to start with, this project will reference code from the following projects:

device/generic/goldfish-opengl # master branch
platform/external/qemu/ # emu-master-dev branch

Once the minimum set of code dependencies is determined, they will be extracted out to this project. We'll also use those to get the initial version of the code working on both Cuttlefish and Goldfish.

After this extraction and verification step, all the needed code for gfx streaming kit will be contained in this project, but the toolchain prebuilts for host side still need to be included as other projects. Therefore, we‘re looking at creating a new repo branch that encompasses this project and the toolchain prebuilts (or any other relevant projects). Thus it’s a good chance to rename this project to something more appropriate like device/generic/gfxstream.

Then, we add a new go/ab target that builds + runs any relevant tests.
