Hi Nguyen, If current PowerPC linux is using the virq to request_irq, you need do the irq_of_parse_and_map(np, 0) to get the virq. like. virq = irq_of_parse_and_map(np, 0) request_irq(virq,...); Hope it can help you. Thanks, Dave

I did try to copy the header file to directory asm-powerpc From MPC8313 datasheet, I have GPIO_IRQ = 74 and I use DEVICE_NAME = "ppc" IRQ_FLAG = IRQF_SHARED // use new flag here my function call request_irq (GPIO_IRQ, ppc_ISR, IRQ_FLAG, DEVICE_NAME, NULL); I'd appreciate any help on this problem. Best Regards, Duy-Kyng
