Hi all,
I'm working on a new kernel driver for a mesanet anything i/o board.
(http://mesanet.com/parallelcardinfo.html - the 4I68 FPGA based
PC104-PLUS Anything I/O card)
I've read the "Linux device drivers" book - the must read but I'm having
some trouble whit the pci_register_driver() function. Let me paste the
code since that would make things more clear then I can tell.
#ifndef PCI_VENDOR_ID_ANYIO
#define PCI_VENDOR_ID_ANYIO 0x14F1 // cx8800
#endif
#ifndef PCI_DEVICE_ID_ANYIO
#define PCI_DEVICE_ID_ANYIO 0x8800 //cx800
#endif
#define DRIVER_VERSION "0.01"
static int cards_found=0;
static struct pci_device_id anyio_pci_tbl[] = {
{
.vendor = PCI_VENDOR_ID_ANYIO,
.device = PCI_DEVICE_ID_ANYIO,
.subvendor = PCI_ANY_ID,
.subdevice = PCI_ANY_ID,
},
{0,},
};
static struct pci_driver anyio_driver = {
.name = "anyio",
.id_table = anyio_pci_tbl,
.probe = anyio_probe_one,
.remove = anyio_remove_one,
};
static int __devinit anyio_probe_one(struct pci_dev *dev, const struct
pci_device_id *id)
{
printk(KERN_ALERT "Inside the anyio_probe_one function!!\n");
// more code
}
static int __init anyio_init(void)
{
printk(KERN_ALERT "Hello, world\n");
pci_register_driver(&anyio_driver);
printk(KERN_ALERT "pci_register_driver called\n");
return 0;
}
More code is there but this is the most relevant part (I think) - the
hello world stuff makes its way to the log files as does the
pci_register_driver called stuff, but the inside anyio_probe_one stuff
does not. It seems to me that the probe function never gets executed.
The must logical reason for this is - i tink that it cant find the board
itself with the corresponding ID's however - the printk function should
be executed no?
A small not - the PCI_VENDOR_ID and such are borrowed from the cx88xx
modules (tv card) since this card is in my machine and I don't use it -
I thought i might use it for testing. (the boards itself are at the
university - and its still vacation :D) .
Any ideas? - thx in advance,
