* \brief Used to return info to PPE on which jobs are completed.
45
* When each SPE is initalized, it is passed EA pointers to two of
46
* these structures. The SPE uses these to communicate which jobs
47
* that it has worked on are complete. The SPE notifies the PPE by
48
* sending an OP_JOBS_DONE message (see gc_mbox.h) with an argument of
49
* 0 or 1, indicating which of the two comp_info's to examine. The
50
* SPE sets the in_use flag to 1 before DMA'ing to the PPE. When the
51
* PPE is done with the structure, it must clear the in_use field to
52
* let the SPE know it can begin using it again.
