23 /* This SPE API basically provides 3 ways to run and control a program
24 * on the SPE:
25 * - Start and stop the program (keepalive=0).
26 * SPE_Start() will implicitly boot up the program, create a thread and run
27 * the context.
28 * SPE_Stop() will join the (terminated) thread (may block) and return.
29 * - Boot the program and run it (keepalive=0).
30 * SPE_Boot() will create a context and load the program and finally start
31 * the context with SPE_Start().
32 * SPE_Stop() will savely end the program.
33 * - Boot, Run and send messages to the program (keepalive=1).
34 * Start the program by using one of the methods described above. When
35 * received the READY-message the program is in its infinite loop waiting
36 * for new messages.
37 * Every time you run the program, send SPU_START and the address of the
38 * according struct using SPE_SendMsg().
39 * SPE_WaitForMsg() will than wait for SPU_FIN and is blocking.
40 * SPE_Shutdown() sends SPU_EXIT and finally stops the program.
41 *
42 * Therefor the SPE program
43 * - either runs once and returns
44 * - or runs in an infinite loop and is controlled by messages.
