OK ... I have to check this with the manufacturer of the board.

Many thanks for the clarification.

In QNX 6.5.0 pci_attach_device() don't have flags like PCI_USE_MSI or
PCI_USE_MSIX.

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.

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 ..

You don't generate an MSI to the FPGA, the FPGA will generate interrupts
to the processor.

Yes, you are correct FPGA will generate interrupt to the processor.
Before and after generating FPGA interrupt to the processor I need to send
some message to FPGA.

What messages are sent over the PCIe lane is deeply embedded in the 
hardware and you and the OS have no access the PCIe message protocol.
You have to map the assigned shared memories of your PCIe board into 
your memory space.
The FPGA reads/and writes to these shared memory segments ... so you 
have to know from which position which data the FPGA reads and where the 
FPGA is placing its response into the shared memory.
But this can only be answered from your "guy behind the chip scope" ...

BTW I'm doing also some developments with FPGAs ...

Good luck.

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

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 ..

The code is for

Would you please help me...

Just a question about the interrupt number used in

id=InterruptAttach(10,intr_handler,0,0,_NTO_INTR_FLAGS_PROCESS);

is this the same IRQ as reported by pinfo->irq ? Normaly you have to use 
the interrupt number reported by pci_attach_device.
But there is still a bug in pci_attach_device because it returns for 
unknown reasons wrong IRQ numbers.

Please check if pinfo->irq is the IRQ reported by pci -vv or lspci -vv

Would it not make more sense to do the write action

pdw = base_ptr[0];
*pdw = 0x01020304;

after start of the interrupt thread ??

And you are writing in the main prog then to the right place and the 
right pattern ?

Now I have completed some part of my task.
Now I need to send bulk of data with packet for this may be I need to use DMA transactions.
Would u pls help me?

Yes when I send data like 01020304 FPGA creates Interrupts again when I send 05060708 disables the Interrupts.
 Now I need to send bulk of data(1024bytes) with single packet.

OK ... sounds great !

If the PCIe chip has a DMA interface you need at first a DMA buffer.
The proc below allocates one.

// allocate DMA memory
void *dma_malloc(uint32_t len, off_t * paddr)
{
void * vaddr;

vaddr = mmap( 0, len, PROT_READ|PROT_WRITE, 
MAP_PHYS|MAP_ANON|MAP_PRIVATE, NOFD, 0 );
if(vaddr == NULL)
return(NULL);
if(mem_offset( vaddr, NOFD, 1, paddr, NULL ))
return(NULL);
return(vaddr);
}

The physical address of the buffer is located in paddr ... you have to 
use it for feeding your DMA interface.
The returned address is the address of the DMA buffer located in your 
address space.

If DMA isn't supported you have to map different base address registers 
which are referencing plain data memory segments of the board.
