Re: [rtl] using fifo in kernel space.

[Robert Kavaler <kavaler@berkeley.innomedia.com>]

You can think of the non-rt kernel as the idle task for the rt kernel. 
 So, you can use all of the rt fifo commands without any problems 
(rtf_put, rtf_get, the posix interface, etc.), you just may get 
preempted by rt kernel since you are the low priority guy.  Note the the 
fifo stuff is designed to handle preemption since it hard disables 
interrupts.  I use fifos in the kernel all the time interfacing to the 
networking code.
