Hi, Mark: Sorry to trouble you, I have a question about the interrupt handling of regmap framework; in the regmap_irq_thread(), from the following code, we only handle the unmasked interrupt;
256 data->status_buf[i] &= ~data->mask_buf[i]; but in the following sequence, irq storm will happen; do you think we should do a change here to handle all the interrupt here? thanks very much; 1) interrupt is triggered; 2) a thread disables it(then the mask bit is set); 3) _Then_ the interrupt thread is executed, it _ignore _ and doesn’t handle this interrupt; because the interrupt is not ACKed, the interrupt status is not cleared; 4) in Marvell's PMIC, the interrupt line to SOC is always asserted, then irq storm happens; ------------------------ Yi Zhang -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
