+/**
+ * DOC: Xe Error Signatures (SIGID)
+ *
+ * What SIGID stands for
+ * ---------------------
+ *
+ * SIGID is short for *Signature Identifier*. A SIGID is a small, stable integer
+ * that names one *recognised Xe fault situation* -- nothing more. It is the
+ * primary handle used for triage: a SIGID maps to a human description and a
+ * recommended first action. A coarse first-order action is documented in-tree
+ * per SIGID (see "First-order action" below) so the id is actionable on its
+ * own; published end-user documentation refines it with finer, cross-product
+ * detail. The driver's only job is to emit the right SIGID next to the usual
+ * human-readable text.
+ *
+ * Why this exists
+ * ---------------
+ *
+ * Today the driver reports faults with ad-hoc ``drm_err()`` / ``xe_gt_err()``
+ * strings that have no stable shape. That is fine for a human reading dmesg,
+ * 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?"
+ * A SIGID answers exactly that one question, identically across driver and
+ * firmware versions, and (eventually) across other Intel devices in a node.
+ *
+ * What a SIGID is (and is not)
+ * ----------------------------
+ *
+ * A SIGID names *which situation* is being reported. It deliberately does not
+ * encode the detailed reason or the outcome. Those are carried alongside it::
+ *
+ *   SIGID    -> which recognised situation is being reported
+ *   severity -> how serious this instance is (see below -- not fixed per SIGID)
+ *   errno    -> the failing operation's error, shown with %pe
+ *   message  -> free-form human-readable context
+ *
+ * Severity is independent of the SIGID. The same situation can be reported at
+ * different severities depending on the instance and the recovery taken, so a
+ * SIGID is never tied to one severity; the reporting site chooses it by calling
+ * the matching xe_log_*() helper (see xe_log.h).
+ *
+ * How to pick a SIGID (the uniqueness rule)
+ * -----------------------------------------
+ *
+ * Pick per *report site*, not per incident. Each site emits the single most
+ * specific recognised situation *for that site* -- so the question is never
+ * "classify this whole failure", it is "what does this site detect?", which has
+ * one answer. A single underlying failure therefore legitimately produces a
+ * *chain* of reports from different layers, each with its own SIGID -- e.g. a
+ * GuC communication failure is reported as %XE_SIGID_RUNTIME_FW by the firmware
+ * path, the failed recovery as %XE_SIGID_GT_TDR by the reset path, and an
+ * aborted bind as %XE_SIGID_PROBE by the probe path. That chain lets triage
+ * follow a fault from origin to final effect; it is not a duplicate.
+ *
+ * If a site does not match any defined situation, keep using the ordinary
+ * ``xe_err()`` / ``xe_gt_err()`` logging rather than forcing a SIGID: a wrong
+ * or over-broad classification is harder to retire than a missing one. When a
+ * new situation is genuinely worth triaging, add it to the list below.
+ *
+ * Scope: software-emitted signatures only
+ * ---------------------------------------
+ *
+ * This header enumerates only the situations that the *driver itself* detects
+ * and reports from software: probe abort, wedged, survivability, driver-
+ * detected firmware failures, engine TDR, memory faults and IO/bus faults.
+ * These are the only values the driver assigns.
+ *
+ * Signatures that *originate* in firmware or hardware are a different thing:
+ * they are produced and identified by the firmware or the hardware itself
+ * (e.g. via their own records or error counters), and the driver merely logs
+ * them as they are given to us. They are deliberately *not* enumerated here --
+ * minting a driver-side id for a firmware/hardware-reported error would only
+ * duplicate an identifier the reporting layer already owns. The two
+ * driver-detected firmware situations below (%XE_SIGID_RUNTIME_FW,
+ * %XE_SIGID_DEVICE_FW) are software signatures: they mark that *the driver*
+ * observed a firmware problem, not a signature reported by the firmware.
+ *
+ * Numbering
+ * ---------
+ *
+ * SIGIDs are a single flat list numbered sequentially within the assigned range,
+ * in the order the situations were introduced. Values are stable: once assigned
+ * they are only ever appended, never renumbered or reused.
+ *
+ * A retired situation is deprecated in place, never re-purposed.
+ *
+ * First-order action (resolution buckets)
+ * ---------------------------------------
+ *
+ * So that a SIGID is actionable on its own, each one is tagged with a coarse
+ * *resolution bucket*: the first thing an operator should do on seeing it. The
+ * bucket is a stable, driver-owned hint; external documentation may refine it,
+ * but the in-tree value always stands on its own. Every new SIGID must pick a
+ * bucket, which forces the question "what should someone do about this?" to be
+ * answered up front. The buckets are::
+ *
+ *   COLLECT  -- capture logs and open a bug report
+ *   RETRY    -- transient or already recovered; watch for recurrence
+ *   UPDATE   -- a firmware update / flash is required
+ *   RECOVER  -- an explicit recovery step is needed (rebind, bus reset)
+ *   IGNORE   -- ignore if the SIGID severity is INFORMATIONAL
+ *
+ * The bucket is documentation only -- it is recorded per SIGID in the enum
+ * kernel-doc below and is not printed on the (deliberately lean) dmesg line.
+ *
+ * When to use SIGID logging
+ * -------------------------
+ *
+ * The xe_log_*() helpers are for these recognised fault situations only --
+ * important, operator-relevant faults and events. They are not a replacement
+ * for ``xe_info()`` / ``xe_dbg()`` / tracing, nor for one-off diagnostics;
+ * using them for ordinary logging would dilute the fault stream. Not every
+ * ``xe_err()`` needs to become a SIGID report -- only those that correspond to
+ * a published situation.
+ *
+ * dmesg vs. the machine record
+ * ----------------------------
+ *
+ * The dmesg line stays close to a normal xe error message so it remains
+ * readable for admins; the only stable, machine-matchable token on it is
+ * ``SIGID=<n>`` (``dmesg | grep SIGID=``). dmesg is not an ABI: the surrounding
+ * text may change freely, and lines may be dropped. The durable record for
+ * tooling is the CPER record carrying the same SIGID (generation is a planned
+ * follow-up).
