     37  * DOC: uevents generated by i915 on it's device node

     39  * I915_L3_PARITY_UEVENT - Generated when the driver receives a parity mismatch
     40  *	event from the gpu l3 cache. Additional information supplied is ROW,
     41  *	BANK, SUBBANK, SLICE of the affected cacheline. Userspace should keep
     42  *	track of these events and if a specific cache-line seems to have a
     43  *	persistent error remap it with the l3 remapping tool supplied in
     44  *	intel-gpu-tools.  The value supplied with the event is always 1.
     45  *
     46  * I915_ERROR_UEVENT - Generated upon error detection, currently only via
     47  *	hangcheck. The error detection event is a good indicator of when things
     48  *	began to go badly. The value supplied with the event is a 1 upon error
     49  *	detection, and a 0 upon reset completion, signifying no more error
     50  *	exists. NOTE: Disabling hangcheck or reset via module parameter will
     51  *	cause the related events to not be seen.
     52  *
     53  * I915_RESET_UEVENT - Event is generated just before an attempt to reset the
     54  *	the GPU. The value supplied with the event is always 1. NOTE: Disable
     55  *	reset via module parameter will cause this event to not be seen.
