Porting Linux to new ARM based application processors has recently become easier than ever: the kernel gained many new frameworks like common-clock, oftree and pinmux. However, things get complicated when it comes to high end embedded graphics units.Those graphics systems tend to be composed of a multitude of on-SoC functional blocks that can operate on shared graphics buffers and video signals, as well as off-SoC encoder/converter chips that can be mixed and matched with any SoC.The old framebuffer is certainly not enough for today's hardware any more, while modern frameworks like KMS and DRM have their own hassles on non-PC style graphics systems.The talk outlines issues we found while working on graphics and video support for the MX53 and MX6 CPUs and gives suggestions for possible future improvements.This presentation is aimed at developers interested in the linux graphics stack. ... https://www.youtube.com/watch?v=NRJR8vqDGBI
