/**
+ * DOC: Xe Device Wedging
+ *
+ * Xe driver uses drm device wedged uevent as documented in Documentation/gpu/drm-uapi.rst.
+ * When device is in wedged state, every IOCTL will be blocked and GT cannot be
+ * used. Certain critical errors like gt reset failure, firmware failures can cause
+ * the device to be wedged. The default recovery method for a wedged state
+ * is rebind/bus-reset.
