/**

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

 *

 * I915_L3_PARITY_UEVENT - Generated when the driver receives a parity mismatch

 *	event from the gpu l3 cache. Additional information supplied is ROW,

 *	BANK, SUBBANK, SLICE of the affected cacheline. Userspace should keep

 *	track of these events and if a specific cache-line seems to have a

 *	persistent error remap it with the l3 remapping tool supplied in

 *	intel-gpu-tools.  The value supplied with the event is always 1.

 *

 * I915_ERROR_UEVENT - Generated upon error detection, currently only via

 *	hangcheck. The error detection event is a good indicator of when things

 *	began to go badly. The value supplied with the event is a 1 upon error

 *	detection, and a 0 upon reset completion, signifying no more error

 *	exists. NOTE: Disabling hangcheck or reset via module parameter will

 *	cause the related events to not be seen.

 *

 * I915_RESET_UEVENT - Event is generated just before an attempt to reset the

 *	the GPU. The value supplied with the event is always 1. NOTE: Disable

 *	reset via module parameter will cause this event to not be seen.
