Today the driver reports faults with ad-hoc drm_err()/xe_gt_err() strings that have no stable shape. That is readable for a human, but it gives fleet tooling nothing durable to match on: the wording changes between releases, lines can be rate-limited or dropped under an error storm, and there is no consistent way to ask "which recognised fault just happened?". Introduce a signature identifier (SIGID): a small, stable integer that names one recognised Xe fault site and serves as the primary handle for triage. A SIGID maps, through published end-user documentation, to a description and a recommended action; the driver only has to emit the right SIGID next to the usual human-readable text.
