+ /* register interrupt handler */ + err = request_irq(priv->trx_irq, &omapl_rx_can_intr, IRQF_SHARED, + "pru_can_irq", ndev);you're doing a lot of work _in_ the irq handler. Maybe threaded irq?SG -Ok, will doNo, please use NAPI instead.We are using h/w filters, so the number of interrupts coming into the processor are not hogging it. I feel that we may not require an interrupt mitigation.
