List-Id: "Xenomai life and development \(bug reports, patches, discussions\)" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Xenomai-core@domain.hid Hi all, using an oscilloscope I found that the AT91RM9200 spends up to 300=B5s in= the interrupt handler for ethernet controller. Now I wonder if this interrupt handler will be preempted by Xenomai if th= ere is a high priority, periodic real time task? Thus will the duration of th= e ethernet interrupt handler add the the worst case latency? Thanks. --=20 Steven
