How to attach to interrupt of bridge RRS feed

  • Question

  • Hi Forum,

    I'm in process of making driver for complex device. This device consist of DMA controller, PCI-to-PCI transparent bridge and Nontransparent bridge attached to transparent one. All that are same ship.

    My problem - to see and use NonTransparent bridge I use standard pci.sys driver from windows and for DMA and Nontransparent bridge I have my driver. Recently I have realized that I have 2 interrupt lines allocated for my device - one for DMA and one for transparent bridge. When interrupts generated by nontransparent bridge they are  coming through transparent bridge interrupt line.

    How can I install interrupt handler to receive interrupt from transparent bridge?

    Thanks,
