+
+@table @code
+@item info spu event
+@kindex info spu
+Display SPU event facility status.  Shows current event mask

+Display SPU signal notification facility status.  Shows pending
+signal-control word and signal notification mode of both signal
+notification channels.

+in order of processing, in each of the SPU Write Outbound,
+SPU Write Outbound Interrupt, and SPU Read Inbound mailboxes.

+@item info spu dma
+Display MFC DMA status.  Shows all pending commands in the MFC
+DMA queue.  For each entry, opcode, tag, class IDs, effective
+and local store addresses and transfer size are shown.
