Re: [Xen-devel] xen/arm: Query - vgic nr_spis value for domU

domU should get configurable nr_lpi in the same way Julien has done for
spi. Unless it is possible to make nr_lpi dynamic based on the guests
actual usage patterns (i.e. alloc on demand), that would be ok too.

You have to expose the number of LPI's used in GICD_TYPER.
So unless we decide to use hardware value for the guest, we would have to
set a static one at domain creation.
