<div>Hi Scott,</div>
<div> </div>
<div> I try to request an IRQ (IRQ2 and IRQ3 which are ineterrupt no 20 and 21 in mpc8247)in my driver . The</div>
<div>Call fails in setup_irq in Manage.c at /kernel/irq. </div>
<div> </div>
<div>Setup _irq returns -ENOSYS</div>
<div> </div>
<div><font color="red">if (desc->irq_data.chip == &no_irq_chip)</font></div>
<div><font color="red"> return -ENOSYS;</font></div>
<div><font color="red"> </font></div>
<div>I just want to know why it fails. Below is the call to request irq in my driver. </div>
<div> </div>
<div> </div>
<div>#define CPLD1_INTERRUPT 20</div>
<div>if <b>(request_irq(CPLD1_INTERRUPT,cpld_irq_handler, 0, GPIO_CHAR_PATH, NULL</b>))</div>
<div> {</div>
<div> printk(KERN_ERR "gpio_init: Could not grab IRQ line for CPLD\n");</div>
<div> goto err1;</div>
<div> }</div>
<div> </div>
<div>Regards,</div>
