Hello,
I am new to device driver environment. I am writing a character device driver a PCI card in 4.3 FreeBSD. I have used the PCI skeleton given on freeBSD.org documents. For the first stage this skeleton should able to detect the specified card.
As per the flow in /sys/kern , it tries to detect all PCI devices present in the system, but I am getting only 2 pci devices.
1. Intel's 82801BA/BAM AC97 Audio Controller with vendor id 0x8086 and device id is 0x2445
and
2. Matrox' MGA-G200 Millennium/Mystique G200 AGP with vendor id 0x102b and device id 0x0521
The card for which I am writing the driver and realtek's 8139 card (which is present in my system) is also not getting detected.
I have tried with WinDriver tool loading on same system(in NT 4.0), there it detects ten pci devices including my card and also realtek's card.
How can I find my card using this skeleton ?
Can anybody help me into this?
Thanks!
Suvarna
