Is there any plan to formally add the gicv3 colorglass4> support to vmm library? Thanks. We at UNSW currently building a new VMM library for the microkit. Right now, it's a port of the existing VMM, and is available in alpha-test state at https://github.com/Ivan-Velickovic/libvmm We're targeting the Odroid C4 at the moment, which has a GIC-400 (GIC v3). The gic-v3 works as a basic GIC, but I'm really hoping that for good performance we'll be able to use some of the IRQ direct injection and other virtualisation features; right now there's noone working on it though. We'd love to review pull requests from anyone else who's working in this area.
