You cannot fix problem of KVM_IRQ_LINE because anyway with this ioctl on ARM you should OR your value with (1 << 24), so this is actually not plain GSI any more. KVM_IRQ_LINE is never used for triggering MSIs, so i think the easiest thing to do is to just leave it doing what it does. As to irqchip routing of irqfd's, why not? By default all GSIs would be SPIs, then this can be changed by userspace, or reverted back... Who cares? When using direct mapping qemu never calls routing functions, so it's OK.
