[Qemu-devel] [PATCH 0/2] Generic PCIe host bridge legacy interrupts routing support
This patch adds: - Function to determine an irq number from qemu_irq. - Function to determine and route legacy interrupts to a VM.

Can you describe in more detail what this patch series is supposed to do, please? Interrupt routing already works fine, via the interrupt controller... thanks -- PMM

GPEX driver is not registering a callback to route INTx and pci_device_route_intx_to_irq() throws a following warning PCI: Bug - unimplemented PCI INTx routing. It also returns -1 as an interrupt number as well as marking it as a disabled one. Hence to complete the GPEX driver in terms of INTx routing I have added this patch but at the same time routing works without this patchset :) . thanks -- PMM Thanks, Pranav
