Description Michael.Baumann 2015-12-08 13:55:47 UTC 
I am missing the support to use the SCHED_DEADLINE policy. 
This policy is available in the mainline Kernel since kernel version 3.14. 
To use it we need the sched_setattr() function and struct sched_attr
according to http://man7.org/linux/man-pages/man2/sched_getattr.2.html

Apparently this issue is still open.

As can be seen in [1], only RR and FIFO are defined. However in [2] (Linux kernel), it is in the mainline.

If I can get some support, I can try to integrate it into glibc as well.
