Ok the IRQ allocation works then, the difference is when the mapping is called, original patch series moves the IRQ allocation to device probe time (that's why IRQ does not show up, there is no matching driver in the kernel for the PCI device above), with the additional patch the IRQ allocation is done when the PCI device is added. It is a user visible change, not sure though if that's a real issue, that's exactly the reason why I posted this series, to find out and converge. Thanks ! Lorenzo
