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

Make sure you are using Clang as your CC and CXX. Then

mkdir build
cd build
cmake . ../
make -j24

TODO: guest build makefiles (Android.bp)

Structure

  • CMakeLists.txt: specifies all host-side build targets. This includes all backends along with client/server setups that live only on the host. Some
    • Backend implementations
    • Implementations of the host side of various transports
    • Frontends used for host-side testing with a mock implementation of guest graphics stack (mainly Android)
    • Frontends that result in actual Linux/macOS/Windows gles/vk libraries (isolation / fault tolerance use case)
  • Android.bp: specifies all guest-side build targets for Android:
    • Implementations of the guest side of various transports (above the kernel)
    • Frontends
  • BUILD.gn: specifies all guest-side build targets for Fuchsia
    • Implementations of the guest side of various transports (above the kernel)
    • Frontends
  • base/: 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. APIs that consume protocol.
  • stream-servers/: implementations of various backends for various graphics APIs that consume protocol. gfxstream-virtio-gpu-renderer.cpp contains a virtio-gpu backend implementation.
