Intro
Wayland is the new protocol dedicated to replace X11 windowing system. It's first Linux implementation is called weston. It uses KMS/DRM video drivers direct access, and so needs a recent kernel (4.4+). It currently works well on APF6.
Installation
Use corresponding config (apf6_wayland_defconfig), or activate it in menuconfig:

Launching
- Needs to be done from a graphical/framebuffer console. To activate one: Framebuffer.
- Login to graphical console / tty1
- Do some config the first boot:
# mkdir /tmp/runtime # chmod 0700 /tmp/runtime # export XDG_RUNTIME_DIR=/tmp/runtime
- Start weston
# weston -B drm-backend.so
Tips
- For OpenGL/ES demos, it is necessary to increase Linux kernel allocable video memory at boot:
BIOS> setenv extrabootargs '${extrabootargs} cma=256M'
