Hello all, The problem i faced in Registering Interrupt in Xenomai, if my interrupt line is shared with the ethernet irqs.
If we register for the interrupt line which is shared by ethernet irqs we will get the continuous interrupt. According to the Xenomai interrupt handling - we should return RTDM_IRQ_NONE for unhandled interrupt. and RTDM_IRQ_HANDLED for interrupt handled. the problem if I return RTDM_IRQ_NONE, system get hanged with message __XINTIRQ_ No Body cared for IRQ 19 IRQ 19 - same irq sharing with ethernet & my module. If instead of RTDM_IRQ_NONE i will return 0; it will not hang. but i am not sure about the functionality when it wil share with some other irq which is important. what is the meaning of returning 0 from Xenomai ISR?
