/**

|
* 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.
