Do you send me any sample code for generating MSI in QNX(to Master FPGA)?

Please realize that only the PCI Express board can send MSI interrupt messages to the Intel chipset.

That means: PCIe chip ---->>> sends Message Signaled Interrupt (MSI) ---->>> chip set ---> CPU
There is NO way to do it in the reverse direction. That's the way the hardware has been designed ....

SP1 is the "Service Pack 1 of QNX 6.5.0" ... it fixes several issues. 
You can download it from the QNX homepage.
Or ask your distributor for the related CDs ..

Armin,

These functions are part of the pci_attach_device() function call. In the
flags section you either add PCI_USE_MSI or PCI_USE_MSIX depending on
which interrupt type you want to use. If you use these flags and the
device doesn't support MSI or MSIX, the PCI server will default to IRQ
interrupts.

Hugh.
