Armin,

No, the flags are only used in the pci_attach_device() function.

Hugh,

many thanks for the info. is there a way to use this flags for e.g. pci_find_device?

Regards

Armin

These flags are to inform the pci-bios-v2 server to either use MSI or MSI-X interrupts rather than the default irqs. If 
a device can use both MSI and MSI-X interrupts and the MSI flag is specified, then only MSI interrupts will be allocated

Hugh,

the flags PCI_USE_MSI and PCI_USE_MSIX are not documented.

What are their semantic?  Does it work with the current version of pci-bois-v2 ?

Best Regards

Here is some sample code to allow you to attach to a PCI device and read
the configuration space. You run the program as 'pci_att 0xVendor
0xDevice' where Vendor and Device are the vendor and device Ids of the
device you are concerned about.

If your FPGA supports bus mastering, then all you need to do is setup the
physical address of the memory buffer in the FPGA and the FPGA will bus
master to/from this address.

As I have said before, I don't know how your FPGA works, so you will have
to contact whoever designed your FPGA.
