An inconvenient part of GPU driver development is the fact that GPUs can crash and hang for various reasons, just like CPUs. Really, this can happen on any operating system to GPUs from any manufacturer. We’ve seen many such issues on the open source Linux driver stack for AMD GPUs. We’ve been tackling many bugs that lead to GPU hangs. We need to deal with the fact that hangs can happen and when they happen, we need to make sure that the system can recover and the user can keep using their Linux desktop. The purpose of this blog post is to give an overview of what the problem is and what steps we are taking to improve it.
