I have maybe stupid question. From QNX I know every each driver acts
as process having threads. Each thread has schedulinng scheme and it's
own priority. How it's in Linux? I mean no user space, but kernel
space. It looks for me like unpredictable bunch of mess. Can I somehow
manage priorities even for the drivers? I'm using Denx's distribution.
Or do I have to use some extensions? It looks like a problem with
porting of already existing applications running on PC down to
embedded slower CPUs. Specially streaming applications.
