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. | |

995 | * the object is still in-flight on the GPU. (The GPU has not yet | |
996 | * signaled completion for all pending requests that reference the | |

998 | * long as no new GPU commands are executed upon it). Due to the | |
999 | * asynchronous nature of the hardware, an object reported | |
1000 | * as busy may become idle before the ioctl is completed. | |
1001 | * | |
1002 | * Furthermore, if the object is busy, which engine is busy is only | |
1003 | * provided as a guide. There are race conditions which prevent the | |
1004 | * report of which engines are busy from being always accurate. | |
1005 | * However, the converse is not true. If the object is idle, the | |
1006 | * result of the ioctl, that all engines are idle, is accurate. | |
1007 | * | |
1008 | * The returned dword is split into two fields to indicate both | |
1009 | * the engines on which the object is being read, and the | |
1010 | * engine on which it is currently being written (if any). | |
1011 | * | |
1012 | * The low word (bits 0:15) indicate if the object is being written | |
1013 | * to by any engine (there can only be one, as the GEM implicit | |
1014 | * synchronisation rules force writes to be serialised). Only the | |
1015 | * engine for the last write is reported. | |
1016 | * | |
1017 | * The high word (bits 16:31) are a bitmask of which engines are | |
1018 | * currently reading from the object. Multiple engines may be | |
1019 | * reading from the object simultaneously. | |
1020 | * | |
1021 | * The value of each engine is the same as specified in the | |
1022 | * EXECBUFFER2 ioctl, i.e. I915_EXEC_RENDER, I915_EXEC_BSD etc. | |
1023 | * Note I915_EXEC_DEFAULT is a symbolic value and is mapped to | |

1026 | * execution engines, e.g. multiple media engines, which are | |
1027 | * mapped to the same identifier in the EXECBUFFER2 ioctl and | |
1028 | * so are not separately reported for busyness. | |
1029 | * | |
1030 | * Caveat emptor: | |
1031 | * Only the boolean result of this query is reliable; that is whether | |
