HI all, I have the following problem: I have a device driver using mq's for incoming / outgoing data (under interrupt) Afaik mq functions (rt1.1 style from semaphores/rt_ipc.c) can only be called from rttasks and not from kernelspace (and fifo handlers run in kernelspace correct?!) Hence I need to create a a rttask (thread) which reads data for me from this mq. In the meanwhile I want / need the fifo handler to wait untill this task is done. So this gives me a few questions: -Is it correct that I can only call mq functions from semaphores/rt_ipc.c from rttasks and not from kernelspace? -What happens when I create a task which actually finishes i.o.w it returns is this safe, and equal to just deleting it? -How can I lett my kernelspace fifo handler wait? should i just use sleep_uninterruptable in a loop and check some kinda done flag? or is there a better way?
