41  * DOC: uevents generated by i915 on it's device node
42  *
43  * I915_L3_PARITY_UEVENT - Generated when the driver receives a parity mismatch
44  *	event from the gpu l3 cache. Additional information supplied is ROW,
45  *	BANK, SUBBANK, SLICE of the affected cacheline. Userspace should keep
46  *	track of these events and if a specific cache-line seems to have a
47  *	persistent error remap it with the l3 remapping tool supplied in
48  *	intel-gpu-tools.  The value supplied with the event is always 1.
49  *
50  * I915_ERROR_UEVENT - Generated upon error detection, currently only via
51  *	hangcheck. The error detection event is a good indicator of when things
52  *	began to go badly. The value supplied with the event is a 1 upon error
53  *	detection, and a 0 upon reset completion, signifying no more error
54  *	exists. NOTE: Disabling hangcheck or reset via module parameter will
55  *	cause the related events to not be seen.
56  *
57  * I915_RESET_UEVENT - Event is generated just before an attempt to reset the
58  *	the GPU. The value supplied with the event is always 1. NOTE: Disable
59  *	reset via module parameter will cause this event to not be seen.
