Hello Jaswinder, > Is it possible to run softirq-threads or IRQs as a non-realtime tasks > in RT kernel. Currently the answer is no. (Unless overruled from userspace) I did not take this requirement into account. So, Is this a serious requirement? Should this be possible? I cannot imagine a purpose in which that is wanted, it would cause unpredictable interrupt handling, and I can imagine that many drivers/devices will not like that. The purpose is usually to spread the threads across several priorities, to create room for some RT-process to become more important than an IRQ that generates large latencies, and each RT-system designer shall divide the priorities different, due to different system requirements.
