Hi
I have a question disturb me very much.
You know linux FIFO policy is common,and also there are many drivers
running in system,so
which level are these drivers running on? If I have a progrom which
priority is FIFO99, does it disturb the driver running?
I want know which level does drivers running on? For example, driver
running on FIFOXX? and how does linux schedule on this
case?

Thanks!
Best Regards!
