[Xenomai-help] RTDM : Obtaining PCI base address

[Ramon <ramoncostacastello@domain.hid>]

Hi,

In order to introduce myself to RTDM and driver development in Xenomai, 
I'm trying to develop a simple "driver"
for an advantech PCI-1711 card.

First thing I need to do is obtaining the PCI base address of the card. 
To do this I used an old code I already have :

struct pci_dev *pcidev;

printk("PCI-1711 DETECT PCI \n");
pcidev=NULL;
pcidev =pci_get_device (PCI_VENDOR_, PCI_DEVICE_, pcidev );
if (pcidev==NULL){
	printk("PCI-1711 CANNOT BE FOUND \n");
}
else{
     printk("PCI-1711 LOCATED \n");
     if (pci_enable_device(pcidev)){
       printk("PCI-1711 NOT ENABLED \n");
       return(-EIO);
     }
     else{
         printk("PCI-1711 ENABLED \n");
	}
     PCI_BASE_ADRESS_1711= pci_resource_start(pcidev, 1)&    PCI_BASE_ADDRESS_MEM_MASK;
     printk("PCI-1711 DETECT PCI %x \n",PCI_BASE_ADRESS_1711);
}



Unfortunatelly PCI_BASE_ADRESS_1711 always takes de 0 value.

Is this type of code already valid in current linux kernels ?
Could anyone point me to a similar code ?

Thank you in advance
Ramon
