our hardware guys are designing an pci/ide controller which has
interrupt wrapper such that the ide & bus master interrupts are
packaged & delivered together.

All the SFF8038i/D1510 style devices have a single interrupt line for
IDE and for bus mastering interrupts. If your device behaves in
accordance to D1510 the default code ought to work.

thanks alan. i will have look into it.

one more question - we are planning two channel bus-mastering design. whether linux ide sub-system will support simultaneous dma kick sequences?
