Debug issues related to display can be a challenge due to the complexity around this topic and different source of information might help in this process. We already have support for tracepoints inside the display component, i.e., we have the basic functionalities available and we just need to expand it in order to make it more valuable for debugging. For this reason, this patchset reworks part of the current tracepoint options and add different sets of tracing inside amdgpu_dm, display core, and DCN10. The first patch of this series just rework part of the current tracepoints and the last set of patches introduces new tracepoints.
This first patchset version is functional. Please, let me know what I can improve in the current version but also let me know what kind of tracepoint I can add for the next version.
Finally, I want to highlight that this work is based on a set of patches originally made by Nicholas Kazlauskas.
