Automotive Linux Summit 2014

Panasonic presents “issues and solutions for applying Window System (Wayland/Weston) to Infotainment Unit Development”. In Infotainment Unit Development, lightweight Window System is required, which can accept client rendering by using OpenGL ES and composite Multi-Window. Panasonic evaluated whether Wayland/Weston met system requirements of Infotainment Unit. Infotainment Unit requires “simultaneous operation of high frame rate video and HMI animation” and “stable video camera playing for ensuring safety”. But in the evaluation result, because of high GPU load caused by layer composition, these requirements couldn’t be met. Our solution to this problem is to cooperate with BSP offer origin, improve Wayland/Weston to support “multi hardware layer” and “compositor by 2D-GPU”. The improved Wayland/Weston is expected to meet the system requirements of Infotainment Unit.
