Example PCI driver in DDK???

OSR_Community_User · February 14, 2003, 5:24pm

Hello,

I am looking for an example PCI function driver in DDK to no avail. I am using Pci* functions as a way to search. Below a PCI function driver is the PCI bus driver, yes?

Regards, Vasili

Sure is … and when your AddDevice is called you get a PDO to the PCI bus driver below you.

Gary,
Did you see other question? In DDK, were is source code for PCI function driver?
Thanks and regards, Vasili

You don’t have a PCI driver sample in DDK. Where as the toaster sample is
very helpful. But you have a PCI driver from OSR in its resources section.

There is no *need* for a specific sample of a PCI driver. It’s like
looking at an example of a door with an knob on the right and saying,
“yes, but my door has the knob on the left, so how do I open *it*?” The
beauty of the PnP model is that every driver works basically the same
until you get to the device-specific configuration stuff that you do
during IRP_MN_START_DEVICE.

Well actually there is a lot of generic code in a pci driver. Answers to questions like the infamous “are my
BARs ordered in the resources” could be illustrated in code. Busmaster DMA using scattergather lists is
generic up to the actual point where you program the DMA registers on the PCI device. Accessing the config
space is entirely generic. And the answer the the doorknob question question might also be generic (turn
counter-clockwise to open, or turn to the inside to open.

I think it is rather silly that the hardware examples in the DDK are almost without exception ISA (or is
that LPC these days?) devices. A complete example of a MODERN hardware device driver is not too much to ask
for.

Well, okay. I exaggerated to make a point. I’m not sure if it was the
same guy asking the same question in another forum, but I pointed
somebody to the PCI42 and PKTDMA samples in my book, which are for real
PCI hardware.
