I'm trying to learn more about PCI for device driver programming. I'd like to know if the Dragon Board comes with code to build a PCI Configuration Space as specified by PCI-SIG.


Also, I would also like to implement an Ehternet Card using the FPGA...I don't want an entire IP Core in the FPGA, but I would like to have some type of DMA so I could transfer packets from the OS to the wire, mainly sk_buffs (Linux).


Last question, I swear ... I'd also like to know how to generate interrupts so that my device driver would know when to do something.

Thanks

1. Yes. The code shows how to create a minimum configuration space that you can build on.
2. The board comes with demo code to send/receive UDP packets. You can improve it for more protocols.
3. The provided PCI code doesn't use interrupts but that should be relatively easy to add.

Hi!

> .... interrupts should be relatively easy to add.

That would be very interesting to me, any news to this point ?
(Or an update on PCI-Interface-Project planned? )

Thanks.

No, I don't plan to add that right now, it's been a while since I did WDM development.

Wow, thanks for the fast reply

I mean, presupposed access to Windriver-like tools,
any pitfalls to implement an interrupt on the FPGA-side ?
(To tell windows a time critical data-change has happened, or so)

Any comments like "Read the PCI project -Doc´s" are o.k ...

I used Microsoft DDK, no 3rd party tools. Probably even easier with WinDriver. But I didn't do it so I can't really comment.
