Cyclic Scheduling for linux
Hi there,
I am working on providing a cyclic scheduling policy to the current non real time version of the linux to support hard real time tasks as part of one of my projects. This policy should be able to support aperiodic, periodic and sporadic tasks too. Could any one pour some light on how to go about achieving it?.
Any Helpful tips, project reports, links or advices are greatly appreciated.
Thanks and Regards,
LQ

Instead of kernel changes, you might want to consider a user monitor task running at high rt priority which changes the priority of the tasks you want to use the new policy. You could write an intercept routine for the scheduleset* calls and pass the new policy to the monitor. More thought would be needed to make it inherit across a fork..
