Hi Lukas,

Dom0 vGIC will use the same number of interrupt lines as the hardware

While the hardware GIC can support up to 1020 interrupt lines,
the vGIC is only supporting up to 992 interrupt lines.
This means that Xen will not be able to boot on platforms where the
hardware
GIC supports more than 992 interrupt lines.
While it would make sense to increase the limits in the vGICs, this is
not
trivial because of the design choices.
At the moment, only models seem to report the maximum of interrupt lines.
They also do not have any interrupt wired above the 992 limit.
So it should be fine to cap the number of interrupt lines for dom0 to
992 lines.
