> I was reading an article about plan9's realtime scheduler edf (http://doc.cat-v.org/plan_9/real_time/real_time_in_a_real_operating_system/real_time_in_a_real_operating_system.pdf, page 7), and they mentioned using /dev/realtime to create realtime processes, but /dev/realtime doesn't exist on my machine (I am using 9front). I found a post here from 07 saying something about removing it a long time ago, but it got no answers.
> In proc(3) they mention some commands for configuring realtime processes but I don't know if that is to configure an already made realtime process or to make one from a regular. How do i make realtime processes in these days?
it's the bits you found in /proc; there are no (longer?)
any special real time processes; any process can become
real time by setting up deadlines at any point.
/dev/realtime isn't needed any more.
unfortunately, I'm not aware of any programs using it.
(that may be a good question for the list: where was the
real time scheduler used, and does any code using it
