Darm-vgic-its.txt1 ARM Virtual Interrupt Translation Service (ITS)
7 The ITS allows MSI(-X) interrupts to be injected into guests. This extension is
8 optional. Creating a virtual ITS controller also requires a host GICv3 (see
9 arm-vgic-v3.txt), but does not depend on having physical ITS controllers.
11 There can be multiple ITS controllers per guest, each of them has to have
