43 | * I915_L3_PARITY_UEVENT - Generated when the driver receives a parity mismatch | |

35a85ac6 BW |
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. | |
cce723ed BW |
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. | |

858 | * signaled completion for all pending requests that reference the | |
1255501d CW |
859 | * object.) An object is guaranteed to become idle eventually (so |
860 | * long as no new GPU commands are executed upon it). Due to the | |
861 | * asynchronous nature of the hardware, an object reported | |
862 | * as busy may become idle before the ioctl is completed. | |
863 | * | |
864 | * Furthermore, if the object is busy, which engine is busy is only | |
865 | * provided as a guide. There are race conditions which prevent the | |
866 | * report of which engines are busy from being always accurate. | |
867 | * However, the converse is not true. If the object is idle, the | |
868 | * result of the ioctl, that all engines are idle, is accurate. | |
426960be CW |
869 | * |
870 | * The returned dword is split into two fields to indicate both | |
871 | * the engines on which the object is being read, and the | |
872 | * engine on which it is currently being written (if any). | |
873 | * | |
874 | * The low word (bits 0:15) indicate if the object is being written | |
875 | * to by any engine (there can only be one, as the GEM implicit | |
876 | * synchronisation rules force writes to be serialised). Only the | |
877 | * engine for the last write is reported. | |
878 | * | |
879 | * The high word (bits 16:31) are a bitmask of which engines are | |
880 | * currently reading from the object. Multiple engines may be | |
881 | * reading from the object simultaneously. | |
882 | * | |
883 | * The value of each engine is the same as specified in the | |
884 | * EXECBUFFER2 ioctl, i.e. I915_EXEC_RENDER, I915_EXEC_BSD etc. | |
885 | * Note I915_EXEC_DEFAULT is a symbolic value and is mapped to | |
886 | * the I915_EXEC_RENDER engine for execution, and so it is never | |
887 | * reported as active itself. Some hardware may have parallel | |
888 | * execution engines, e.g. multiple media engines, which are | |
889 | * mapped to the same identifier in the EXECBUFFER2 ioctl and | |
890 | * so are not separately reported for busyness. | |
1255501d CW |
891 | * |
892 | * Caveat emptor: | |
893 | * Only the boolean result of this query is reliable; that is whether | |
894 | * the object is idle or busy. The report of which engines are busy | |
895 | * should be only used as a heuristic. | |
