Run Wayland in QEMU

This repository helps you run wayland in qemu. For now it juts runs the tizen image, but this will hopefully change soon.

To run, you will need internet connectivity, then:

./build_qemu
./run_wayland

How it works (in progress)

Seems VIGS is the emulated video hardware, and this can have a GL command stream, which gets rendered by the YaGL part - no idea what the acronyms stand for yet.

On the device side for Wayland, you need

• the modified libdrm with VIGS support (link below)
• a kernel with the VIGS DRM driver
• all the bits in emulator-yagl.git except the xf86 drivers
  • GBM plugin
  • hacked wayland-drm
  • hacked wayland-egl
  • GLES/EGL libaries

I think this works much the same as the GL transport in the google emulator, marshalling the GL calls and then demarshalling on the host and rendering in a sort of GLES(1/2) emulator.

Some useful reading to get a handle on how this works:
