Through the attached file I am sending the output of pci -vvv.
My project board contains both Intel chip and FPGA chip on same board.
through PCI express slot we are connecting Xilinx board. Through PCIe we are
communicating with each other. And the result is checking at FPGA side by
Chipscope software.

Ok ... and this is a board from Xilinx with the vendor ID  10EEh ??

This board seems to be completely disabled ...
No I/O memory, no memory, no connection to an interrupt line.
Also the memory of 128 bytes referenced by BAR[0] is disabled !

Please see the marks at the printouts of the "pci" command:

Vendor ID      = 10eeh, Xilinx Corporation
Device ID      = 7h, Unknown Unknown
PCI index      = 0h

And the previous which you have sent to me is not working because
pci_dev_info predefined structure doesn't contain members like HeaderType,
CpuBmstrTranslation, CpuIsaTranslation, CpuMemTranslation, NumIrq,
info.MsiDefs[i].count

The example code previously posted by Hugh Brown is for QNX 6.5.
Are you working with QNX 6.4.x ??

How to recognize interrupts coming from FPGA through PCI?

is this a board with a PCI interface together with separate FPGA chip??
Or is the PCI interface realized as a core of the FPGA?

Could you post the output of "pci -vvv" ?



Please provide me
document or code regarding this.
