37  * DOC: uevents generated by i915 on it's device node
38  *
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.
