I am working with version 3.14.25-rt22. I have successfully installed the kernel after patching with rt patch of same version. Now the installed kernel also has SCHED_DEADLINE i.e. the EDF scheduling policy. The problem in my hand is to introduce a parameter in the SCHED_DEADLINE policy which will further dynamically change the priority according to the supplied value while the task is submitted. I have already simulated and tested my requirement. I am having problem with understanding the hierarchy of scheduler code. Thanks in advance.
