RT-Linux源码 一个实时操作系统源码

This example show how the work done inside the scheduler can be monitorized.
The scheduler used (and patched to send scheduling info) is the 
rt_monotonic_sched.o, it is a modification of the original 
scheduler (rt_prio_sche.o).

All you have to do is to change variable RTLINUX in the Makefile to
point in you rtlinux2.0.29 directory.

Rate-monotonic scheduler treats tasks with shorter period as tasks with higher
priority.

rt_monotonic_sched:
	Does monotonic scheduling and generate debug information 
	(if you want).
	
rt_process:
	Creates few RT tasks with varing execution time.

app:
	reads FIFO (DEBUG_FIFO)  and writes it to the stdout, in the a special
format than can be displayed by the procam crono.
 
To run the example type:
# make
# make start ( Load modules ).
(wait some time while system is logging the info 1 or 2 seconds)
# crono/crono data.out &
# make stop  ( Remove modules )

Or :
# insmod ${YOUR_MODULES_DIR}/rt_fifo_new.o
# insmod rt_monotonic_sched.o
# app > data.out&
# insmod rt_process.o
