Xe needs to align with other drivers on the way that the error states are dumped, avoiding a Xe only error_state solution. The goal is to use devcoredump infrastructure to report error states, since it produces a standardized way by exposing a virtual and temporary /sys/class/devcoredump device. The initial goal is to have the simple_error_state in the devcoredump so we start using the infrastructure. But this is just a start point to start building a useful and organized crash dump, using standard infrastructure. Later this will be changed to have output that can be parsed by tools and used for error replay. Later, when we are in-tree, the goal is to collaborate with devcoredump infrastructure with overall possible improvements, like multiple file support for better organization of the dumps, snapshot support, dmesg extra print, and whatever may make sense and help the overall infrastructure.
