Hi, Why is Linux kernel considered a (hard) realtime OS? I already understand the basic reason is that the linux kernel does not guarantee that a task will be completed on time. But I would appreciate answers in terms of more of kernel jargons. What stops us from classifying kernel as hard RTOS? Is it because at times the kernel is non-preemptive (for e.g. while holding spinlocks)? Has it got something to do with interrupt latency / scheduling latency etc? Is the behaviour of the kernel (when it is preemptive) similar to hard real time OS ??
