Hi all,
I am running the Linux kernel 2.6.28.7 on my PPC8347 BRD.
I have another problem.
I use many external Interrupts.
one of them ,I setup
local...@f0000000 { //WDT,SW etc.k
reg = <0xf0000000 0x20>;
pci_i...@2{
interrupt-parent = <&ipic>;
interrupts = <17 0x8>;
};
};
on dts file.
And I programmed
struct device_node *np;
struct resource irq_res;
int ret;
char *irqs[]={
"pci_inta",
NULL};
for(i=0;;i++){
if(irqs[i]==NULL){
break;
}
np = of_find_node_by_name(NULL, irqs[i]);
if (np == NULL) {
printk("No %s in DTB. Has it been eaten by wild
dogs?\n",irqs[i]);
return -ENODEV;
}
if (!of_device_is_available(np)){
printk("No %s in DTB.
of_device_is_availables?\n",irqs[i]);
return -ENODEV;
}
ret = of_irq_to_resource(np, 0, &irq_res);
if (ret == NO_IRQ)
irq_res.start = irq_res.end = 0;
else
irq_res.flags = 0;
printk("********************************* %s
irq_res.start=%d,irq_res.end=%d\n",irqs[i],irq_res.start,irq_res.end);
}
printk result is
********************************* pci_inta irq_res.start=19,irq_res.end=19
I set the Interrupt ID number 17.
But kernel gives the Interrupt ID number 19.
I wont to know the reasen.
Please tell me.
