Hello all,
I have written a pci driver for a simple device. It only read and
write from a I/O ports region. (It works)
My structure is: pci_driver and a cdev to create the device file.
And the probe function is: (approximately)
SCLink_probe(struct pci_dev *my_pci_dev, ...)
{
dev_t dev;
pci_enable_device(my_pci_dev);
result = alloc_chrdev_region(&dev, 0, 1, "SCLink");
SCLink_major = MAJOR(dev);
cdev_init(&char_dev, &fops);
char_dev.owner = THIS_MODULE;
char_dev.ops = &SCLink_fops; //file_operations
err = cdev_add(&char_dev, dev, 1);
pci_request_regions(my_pci_dev, "SCLink");
}
//static int __init SCLink_init(void)
// return pci_register_driver(&SCLink_driver);
Is this structure acceptable?
Can I create a char device for each BAR?
Any suggestion?
Thanks in advance ;-)
