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.
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.
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.
