Jungo 8.11 + 3 PLDA ARRIAGX Boards + DMA + IT

Hello,

First :

Do you know if somebody has already inserted three X4 PCIex board in a PC ?

Second:

We perform three parallel DMA transferts (PC memory to PCIex board). At the end of DMA transferts three parallel INTA interruptions are sent.

Do you know if the Jungo driver is able to manage three DMA transferts and interrupt simultaneously ?

Thanks,

Fredlac

info :

Boards = PLDA XPRESSAGX (FPGA ALTERA ARRIAGX)

System = Windows XP

IP PCIex = PLDA (X4, Pcie 1.0)

    Interrupt is generated using a single interrupt line INTA. So, jungo will provide a call to your interrupt service routine(ISR) when there is an interrupt and it is up to your ISR on how to clear and service those three interrupts.
