 This file contains the 2 functions needed to initialize the system.
33
 
34
 These functions register the following levels:
35
 
36
 an EDF   (Earliest Deadline First) level
37
 a  RR    (Round Robin) level
38
 a  TBS   (Total Bandwidth Server) level 0.1 Us
39
 a  TBS   (Total Bandwidth Server) level 0.3 Us
40
 a  Dummy level
41
 
42
 The TBS bandwidth is TBS_NUM/TBS_DEN
43
 
44
 
45
 It can accept these task models (into () the mandatory fields):
46
 
47
 HARD_TASK_MODEL (wcet+mit) at level 0
48
 NRT_TASK_MODEL  at level 1
49
 SOFT_TASK_MODEL (wcet, periodicity=APERIODIC) at level 2,3
