Hello,
i have problems to get my Philips ISP1561 PCI USB Hostcontroller functioning
on my PPC 440 GX board. The Host controller Interrupt Pin is connected to
external IRQ 03 of the PPC 440 GX. So Interrupt 26 should be responsible for
the Host controller and PCIX address line 17 is selected for IDSel. I
configured my Board specific File to that conditions:
static inline int
hima_map_irq(struct pci_dev *dev, unsigned char idsel, unsigned char pin)
{
static char pci_irq_table[][4] =
/*
* PCI IDSEL/INTPIN->INTLINE
* A B C D
*/
{
{ 26, 26, 26, 26 }, /* IDSEL 17 - PCI Slot 0 */
{ 25, 25, 25, 25 }, /* IDSEL 18 - PCI Slot 1 */
{ 24, 24, 24, 24 }, /* IDSEL 19 - PCI Slot 2 */
{ 23, 23, 23, 23 }, /* IDSEL 20 - PCI Slot 3 */
};
const long min_idsel = 1, max_idsel = 4, irqs_per_slot = 4;
return PCI_IRQ_TABLE_LOOKUP;
}
At linux boot process (see below) the device is detected properly. And if i
connect a usb keyboard i got an error message that irq 26 nobody cares.
What i did wrong with my configuration or someone has a hint?
Thanks for any help!
Best regards,
David
