I am trying to list of the pci devices of type storage, for which I have following code,
the code does not find any device. I was expecting to see hard disk and/or drives. What am I doing
wrong.
struct pci_dev *disk=NULL;
while (1)
{
if ((disk = pci_find_class(PCI_BASE_CLASS_STORAGE, disk)) == NULL)
{
printk("End of storage devices\n");
break;
}
else
{
pci_read_config_word(disk, PCI_VENDOR_ID, &vid);
pci_read_config_word(disk, PCI_DEVICE_ID, &did);
printk("Vendor id = %d, Device id = %x\n", vid, did);
printk("Class = %d\n", disk->class);
}
}
