How to tame a Panthor

GPU drivers are probably among the most complicated drivers I have had a chance to work on. Some coding god[ess] might find it fairly trivial, but for the rest of us, mere mortals, it is often too much of a mountain to climb.

In this talk, I will try to demystify what GPU drivers are doing and how, by taking Panthor/PanVK (the kernel+userspace drivers for Mali GPUs) as a case study. I will also go through some of the components provided by the DRM subsystem that makes writing of modern kernel GPU drivers slightly easier.
