Printk won't "print" from probe() ::::A hello world module-pci device

[aladdin]

Good Day,

A very simple hello world kind of module.
It does print message from init and exit routine but from with in probe() function it won't print ant thing.

I suspect probe wont get executed.

#include <linux/module.h>       /* Needed by all modules */
#include <linux/kernel.h>       /* Needed for KERN_INFO */
#include<linux/pci.h>

#define MY_VENDOR_ID  0x109e
#define MY_DEVICE_ID  0x036e

struct pci_device_id my_driver_pci_table[] __devinitdata = {
  {
   MY_VENDOR_ID,
   PCI_ANY_ID,
   MY_DEVICE_ID,
    0,0
  }, {0},
};

static int __devinit  my_driver_probe(struct pci_dev *pdev, const struct pci_device_id *id)
     {
        pci_enable_device(pdev);
        printk("--------------------------------\n");
        printk("message from inside of probe function \n\n");
        printk("--------------------------------\n");

      }


struct pci_driver  my_pci_driver = {
     .name = "mydrv",
     .probe = my_driver_probe,
//   .remove = __devexit_p(my_driver_remove),
     .id_table = my_driver_pci_table,
     };

static int __init my_driver_init(void)
     {
         pci_register_driver(&my_pci_driver);
         printk("--------------------------------\n");
         printk("Msg from init fonction\n\n");
         printk("--------------------------------\n");
         return 0;
     }

static void __exit my_driver_exit(void)
    {
    pci_unregister_driver(&my_pci_driver);
    printk("un registering hello-1\n");
    }


module_init(my_driver_init);
module_exit(my_driver_exit);
MODULE_DEVICE_TABLE(pci,my_driver_pci_table);

output from /var/log/message

Hi,

I am using Fedora 9 -> bought a cd version and installed and i could not find the module.h and kernel.h that contains the necessary interfaces,
printk, init_module(), etc.,

Should i download a new kernel from the kernel tree and recompile ?

In the link below,
Follow the instruction under "kernel source" + "kernel header" and installe kenel source and kernel header.

Personal Fedora 9 Installation Guide


You need to have those 2 in order to build modules.
Fedore doesn't ship kernel source.

Thanks.
