I haven't followed the whole discussion, Alexey, is this the per-host bridge source number or the global XIRR (XICS interrupt number) ? Because in the latter case, it can be up to 24 bits... (And yes, MSI data is limited to 16). However maybe we can decide arbitrarily that under qemu/kvm we only support 16-bit XIRRs (it's fine, from a PAPR perspective at least if it keep things simpler). Cheers, Ben.
