I don't know how irqbalance works, and I'm not sure what you are referring to by BIOS APIC programming, however I would expect these things would not be a problem. The MSI code I'm presenting here doesn't do anything crazy with the interrupts, it allocates and uses them just as any PCI driver would. The only real difference here is that instead of a piece of hardware sending the IRQ TLP, it will be sent through the memory window (which, from the OS's perspective, is just coming from an NTB hardware proxy alias).
