System initialization file |
|
This file contains the 2 functions needed to initialize the system. |
|
These functions register the following levels: |
|
an EDF (Earliest Deadline First) level |
a RR (Round Robin) level |
a CBS (Costant Bandwidth Server) level |
a Dummy level |
|
It can accept these task models: |
|
HARD_TASK_MODEL (wcet+mit) at level 0 |
SOFT_TASK_MODEL (met, period) at level 1 |
NRT_TASK_MODEL at level 2 |
|
This file is similar to the configuration of kernel/init/hartik3.c |
|
TICK is set to 0 (one-shot timer is used) |
