Add input event mouse/touch pointer visualization on the kernel framebuffer
Leon Woestenberg <>


The current kernel framebuffer is an output only interface and relies on higher level libraries for input/output interaction.

For truly minimal systems (such as a Flash player running on the kernel framebuffer) it is very interesting to visualize mouse and touch events from the generic input event layer.

In first instance, this means a mouse pointer drawn on the framebuffer.

Pitfall: this should not become yet another graphics library. Only a mouse pointer to see to visualize mouse or touchscreen input events on the framebuffer.

This should take approx. 3 weeks of development and test effort.
