The kdbus is the low-level, native kernel D-Bus transport and actively developing now. We are trying to replace socket based D-Bus with kdbus based D-Bus on Tizen 3.0 and its products. We have faced many challenges such as compatibility, security, performance, and others. In this presentation, we will share our experience, the current state, the plans, and the benchmark result. We look forward to replacing socket based D-Bus with kdbus based D-Bus for Linux devices, providing better performance transparently.
