64 * 0.04s = 0.032s.
66 This way the graphics group will have a 0.04s period with a 0.032s run time
67 limit. Now if the audio thread needs to refill the DMA buffer every 0.005s, but
68 needs only about 3% CPU time to do so, it can do with a 0.03 * 0.005s =
69 0.00015s. So this group can be scheduled with a period of 0.005s and a run time
70 of 0.00015s.
