Description

Every year, many users and developers adopt AMD dGPU and APU devices; sometimes, they face issues that they need to know if it is a display issue. In this presentation, I want to equip users and developers with debug techniques (for AMD drivers) to help them determine if an issue is really a display problem by sharing some ways to interpret debug logs. I will also show how to narrow issues down to some parts of the source code. At the end of the presentation, I hope the listener can use some of the AMD debugs and test tools and know where to check more about display documentation.

Summary of the topics:

  • Display code overview.
  • Check if an issue is a display problem or not.
  • Provide details about AMD logs (Dmesg, DTN, and UMR registers).
  • Some specific issues (hard hang, MPO, Power issues).
  • IGT.
  • Report bugs and how to contribute.
