28 | System initialization file |
||
29 | |||
30 | This file contains the 2 functions needed to initialize the system. |
||
31 | |||
32 | These functions register the following levels: |
||
33 | |||
34 | an EDF (Earliest Deadline First) level |
||
35 | a RR (Round Robin) level |
||
36 | a CBS (Costant Bandwidth Server) level |
||
37 | a Dummy level |
||
38 | |||
39 | It can accept these task models: |
||
40 | |||
41 | HARD_TASK_MODEL (wcet+mit) at level 0 |
||
42 | SOFT_TASK_MODEL (met, period) at level 1 |
||
43 | NRT_TASK_MODEL at level 2 |
||
44 | |||
45 | This file is similar to the configuration of kernel/init/hartik3.c |
||
46 | |||
47 | TICK is set to 0 (one-shot timer is used) |
