Sending of MSI using IRQ routing is an artificial concept and potentially
big number of MSIs (2048 per device) make it also inefficient. This
patch adds an interface to inject MSI messages from userspace to lapic
logic directly. The patch also reduces the maximum number of IRQ routing
entries to 128 since MSIs will no longer go there and 128 entries cover
5 ioapics and this ought to be enough for anybody.
In the future many MSIs will be triggered via irqfds, and those
require irq routing.
Why? My plan is to change irqfd to use the MSI functions.
It's still an "install handle, call handle" interface. Maybe it would
have been better to start off with your new interface, but having both
is too much for too little gain.
