Hi all,
I am running a 2.6.4 (with preemptible kernel activated). What I did is the following:
1) Compile the sched_test.c program (at the end of the mail):
[root@hermes sched]$ gcc -o sched_test sched_test.c
2) Set the priority of the root shell as the highest:
[root@hermes sched]$ ps
PID TTY TIME CMD
1519 pts/0 00:00:00 bash
2020 pts/0 00:00:00 ps
[root@hermes sched]$ chrt -f -p 99 1519
3) Run sched_test:
[root@hermes sched]$ chrt -f 10 ./sched_test 100
bye now.
Here during the execution of sched_test everything is frozen.
Did I do something wrong ????
