An implementation of the popular Earliest Deadline First (EDF) scheduling algorithm or the Linux kernel. It is still experimental code, and it is still continuously being improved, but it already is a fully-working solution for supporting typical real-time applications in GNU/Linux environments.
hello Juri,
i have successfully booted from the sched-deadline enabled kernel. Please help me ansower the following questions:
Can you please tell me how to to figure out that I have the sched_deadline scheduling class in my kernel.
I tried rt-app, it works for FIFO but not for deadline. The error is as follows:
Error
[rt-app] [0] Using SCHED_DEADLINE policy:
[rt-app] [0] starting thread with period: 10000, exec: 1000,deadline: 8000, priority: 10
[rt-app] [0] Locking pages in memory
[rt-app] [0] setting cpu affinity to CPU(s) [ 0, 1 ]
[rt-app] [0] sched_setscheduler2 returned -1
I would like to test periodic execution of tasks and task groups using cgroups. Is there a special parameter configuration on the cgroups?

am doing my thesis on similar areas,
thank you,
