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!
